If effective management of this waste is not feasible, it can compromise the modern lifestyle, with the potential to contaminate the soil and groundwater, becoming harmful to public health (Ribeiro; Morelli, 2009). The uncontrolled growth of population consumption also generates an increase in waste. During 2016, 78.3 million tons of waste were collected in Brazil (Abrelpe, 2016). Considering this scenario, a viable possibility for mitigating the unfavorable results of the increasing amounts of waste to the ecosystem and public health is to implement Reverse Logistics (RL), ensuring the reduction of waste in the environment. The term Reverse Logistics was promoted in the early 1980s and spread clearly in academic, public and business environments (Pereira et al. , 2012). It was accepted in REVISTA OBSERVATORIO DE LA ECONOMIA LATINOAMERICANA ISSN: 1696-8352 Page 4 REVISTA OBSERVATORIO DE LA ECONOMIA LATINOAMERICANA, Curitiba, v.23, n.3, p. 01-45. 2025. the area of business disposal and began to be responsible for flow controls and logistical procedures related to the return of raw materials to their new production cycle (Adlmaier; Sellitto, 2007). It is possible to observe RL in almost all market sectors. The return of goods occurs every day and for incalculable reasons such as mishaps with raw materials, wrong orders and used products that are returned for their correct recycling (Sabbadini; Pedro; Barbosa, 2005). RL emerged as a tool to contribute to the mitigation – and, if possible, the total eradication – of waste. In 2010, the National Solid Waste Policy (PNRS) was created, the first step of which was to designate shared responsibility among all. This made the entire community, the private sector and the government responsible for the environmental management of solid waste (Sinir, 2012). Since then, legal provisions have increasingly encouraged the design of Reverse Logistics Systems in accordance with the most diverse products, with the aim of covering all of them. Data from the National Information System on Solid Waste Management (SINIR) show that, in force during the time frame of this research (2015/2016), considering nationwide initiatives, Brazil employed four Reverse Logistics Systems implemented prior to Law No. 12,305/2010, through other legal instruments (Unusable tires; Agrochemical packaging; Used or contaminated lubricating oil - Oluc; Batteries) and five Systems created after the PNRS was approved: Plastic packaging for lubricating oils; Sodium and mercury vapor fluorescent lamps and mixed light; Packaging in general; Electronic products and their components; Medicines. Clearly, the achievement of the desired benefits with the implementation of these Reverse Logistics Systems derives from the level of efficiency achieved by them. In this context, this research had the following scope: to gather information regarding the nine Systems mentioned, considering the time frame of 2015/2016, with emphasis on Reverse Flows; Intended Objectives and Goals; Number of collection points and Quantities of products to be returned by the Systems; Create indicators that can be used comprehensively by all the systems addressed, as well as use the AHP method (Analytical Hierarchical Process) to measure the performance of these Systems, in order to classify them considering the established criteria. REVISTA OBSERVATORIO DE LA ECONOMIA LATINOAMERICANA ISSN: 1696-8352 Page 5 REVISTA OBSERVATORIO DE LA ECONOMIA LATINOAMERICANA, Curitiba, v.23, n.3, p. 01-45. 2025. The aim of this research is to substantiate performance foundations for the improvement of the Reverse Logistics Systems studied, as well as to list analyses and considerations that contribute to the topic at hand. To achieve this result, an analysis was made of the nine reverse logistics systems implemented in Brazil - considering the time frame of 2015/2016 - using as a basis a tool constructed - and presented step by step - through the AHP methodology. 2 THEORETICAL FRAMEWORK This topic presents topics related to Reverse Logistics, such as the National Solid Waste Policy, Sectoral Agreements and what Solid Waste is. A brief summary of the nine Reverse Logistics Systems - with national expression - in force in Brazil in the time frame of 2015/2016 - and the research points of the work. 2.1 SOLID WASTE The so-called solid waste includes waste in semi-solid and solid states, coming from sources such as: industries, homes, shops, plantations and hospitals. Also included are sludges that come from the treatment of water and other liquids that cannot return to water bodies or public sewage systems (Abnt, 2004; Schwarzer; Rocha; Seleme, 2021 ). The hazardousness of products can be used to categorize them, and they are then divided into three classes: Class I , which are those wastes established as hazardous , referring to corrosive, flammable, reactive, pathogenic or toxic; Class II , non-inert wastes , such as fuels; and Class III , inert wastes , which do not denote any risk to the environment or health (Abnt, 2004). According to the Brazilian Association of Technical Standards (ABNT), solid waste can also be categorized according to its particularities, such as: Plastics : bags, soda containers, sacks, latex, water and milk containers, raffia bags, cleaning product containers. Chemical contaminants : light bulbs, photographic film, batteries, glues with paints, nail polish, carbon paper, motor oil and chemical product packaging. Biological REVISTA OBSERVATORIO DE LA ECONOMIA LATINOAMERICANA ISSN: 1696-8352 Page 6 REVISTA OBSERVATORIO DE LA ECONOMIA LATINOAMERICANA, Curitiba, v.23, n.3, p. 01-45. 2025. contaminants : hair, razor blades, bandages, gauze, disposable diapers, syringes, bloody cloths, hair, toilet paper and cotton swab (Abnt, 2004; Schwarzer; Rocha; Seleme, 2021). The collection and final disposal of waste is the responsibility of the urban solid waste administration and municipal public administration. Waste that is not collected may end up being disposed of in inappropriate places, commonly being disposed of in vacant lots, streams and rivers, tending to cause clogged drains, bad odors, thus increasing the chances of proliferation of cockroaches, flies and rats, which can spread diseases in the area where the waste is located (Jacobi; Besen, 2011; Schwarzer; Rocha; Seleme, 2021 ). The population of Brazil increased by 0.8% between 2015 and 2016, and waste generation decreased by 3% in the same period, as did total waste generation, which decreased by 2%, reaching 214,405 tons/day of solid waste in the country. However, approximately seven million tons of Urban Solid Waste were not collected during 2016, suggesting inappropriate disposal (Abrelpe, 2016). 2.2 NATIONAL SOLID WASTE POLICY In Brazil, prior to the advent of the Solid Waste Policy, there was no national regulation on the management of solid waste, nor were there any institutions defined to provide guidance on the commitments and obligations of participants in the life cycle of products. However, there were some legal instruments that addressed discipline and spacing of areas (Souza, 2012; Schwarzer; Rocha; Seleme, 2021). Law No. 12,305, of August 2, 2010, published – in December of the same year – the National Solid Waste Policy (PNRS). This law applies to all those who have a direct or indirect relationship with the generation of solid waste (Brasil, 2010; Schwarzer; Rocha; Seleme, 2021). Some of the PNRS's assessments involve protection, caution and sustainable development. All those involved in the production, consumption and disposal of products are leaders of this policy (Brasil, 2010; Schwarzer; Rocha; Seleme, 2021). Recycling and reuse are some of the guidelines of the National Solid Waste Policy. In its seventh article, it defines the following objectives: to protect the characteristics of REVISTA OBSERVATORIO DE LA ECONOMIA LATINOAMERICANA ISSN: 1696-8352 Page 7 REVISTA OBSERVATORIO DE LA ECONOMIA LATINOAMERICANA, Curitiba, v.23, n.3, p. 01-45. 2025. the place and the environment in which one lives, to reduce waste generation if it is not feasible to not generate any, to reuse or recycle everything possible, to encourage consumers to purchase sustainable products and to improve the use of clean technologies (Brasil, 2010; Schwarzer; Rocha; Seleme, 2021). In this sense, LR is one of the tools that corroborates the conception of these precepts, in terms of compiling waste. 2.3 REVERSE LOGISTICS Reverse Logistics (RL) is the part responsible for transporting waste to a suitable location after being used, it is outlined by the National Solid Waste Policy. Reverse logistics involves all merchandise that for some reason is returned to the manufacturer, whether due to product returns, legal issues, excess stock, returned packaging, imperfections, failure to meet expectations, or discontinued products. Packaging and manipulated products also return to the factory to find their proper final destination. It is due to a reverse movement that these products can return to their origins, in the sense of completing their life cycles (Chaves; Alcantara; Assumpção, 2008). Although it does not yet have the ideal infrastructure for the best performance in waste management, LR has, however, been developing and becoming a major differentiator for organizations (Moreira; Bonfim, 2013; Schwarzer; Rocha; Seleme, 2021). LR is linked to the design of the product life cycle, which can be broken down into four steps: Launch , when the product reaches the market, there is little demand and some adaptations are needed in the product; Growth , when the product gains fame in the market and starts to be sold in greater quantities and becomes competitive; Maturation , when the product is already known to customers and its competitors have already formulated a similar product; Decline , when the product becomes obsolete (Wille, 2012) There are two paths for returning products to the company, post-sales and postconsumption; post-sales is the segment responsible for the reverse logistics of products that are not used or used very much, which are redirected to the company for various REVISTA OBSERVATORIO DE LA ECONOMIA LATINOAMERICANA ISSN: 1696-8352 Page 8 REVISTA OBSERVATORIO DE LA ECONOMIA LATINOAMERICANA, Curitiba, v.23, n.3, p. 01-45. 2025. reasons, such as: errors when ordering products, expired expiration dates, inventory problems, lapses and product warranty (Pereira et al., 2012; Schwarzer; Rocha; Seleme, 2021). The distribution path of post-consumer reverse logistics involves greater complexity, being classified into three categories, showing the time elapsed from its original conception to the moment it is first discarded: Durable products , whose average useful phase lasts from years to decades (such as automobiles and electronic devices); Semi-durable products , which have an average productive phase of months - never exceeding 24 months (such as car and cell phone batteries, lubricating oils); Disposable products , with an estimated useful life of less than six months (such as surgical articles, toys, packaging and batteries for electronic equipment) (Pereira et al. , 2012; Schwarzer; Rocha; Seleme, 2021). The product no longer used and reintroduced into the production cycle characterizes reverse logistics; considering its disposal only as a last resort, when it is no longer possible to reuse this waste (Silva et al. , 2006; Schwarzer; Rocha; Seleme, 2021). LR allows companies to be responsible for the final disposal of their solid waste, whether packaging or products, thus preventing them from being rejected erroneously by their consumers. It also helps to reduce the risk of inappropriate disposal of products that are classified as causing risks to the environment, such as lamps, batteries and pesticide packaging (Andrade; Ferreira; Santos, 2009). 2.3.1 Reverse logistics systems implemented in Brazil Considering temporally systems with national scope in force in the years 2015/2016, this topic was divided into two subtopics, covering actions prior to and after the PNRS. 2.3.2 Reverse logistics systems implemented before the national solid waste policy The nationwide systems implemented before the PNRS involve four distinct types REVISTA OBSERVATORIO DE LA ECONOMIA LATINOAMERICANA ISSN: 1696-8352 Page 9 REVISTA OBSERVATORIO DE LA ECONOMIA LATINOAMERICANA, Curitiba, v.23, n.3, p. 01-45. 2025. of waste: agrochemical packaging, unusable tires, used or contaminated lubricating oil (Oluc) and batteries. Specific legislation supported the creation of each of these systems. 2.3.2.1 Pesticide packaging Pesticide residues remain present in the packaging and when these are abandoned in the environment or incorrectly disposed of in landfills or landfills, the toxic elements can contaminate groundwater (Cempre, 2000). Many people, due to lack of information, reuse pesticide packaging in their daily lives, in household tasks, thus aggravating public health problems related to the ingestion of toxic products (Barreira; Junior, 2002). The production and use of packaging and labels, research, transportation, storage, advertising, product use, import and export are defined by Law 7802/89 (Sinir, 2018a). The Law in use for this system is 9,974, of June 6, 2000, which modifies Law 7,802, of July 11, 1989 (Brazil, 2000). The National Environmental Council – CONAMA (2014) states that environmental and health damage occurs when there is an inappropriate use of pesticide and similar packaging. Farmers are responsible for triple washing the packaging and transporting it to collection points offered by retailers (Inpev, 2017a; Conama, 2014; Sinir 2018a). inpEV – National Institute for Processing Empty Packaging – was launched in 2001, with the aim of competently coordinating the final destination of this waste, curbing its inappropriate disposal (Inpev, 2016). 2.3.2.2 Waste tires Due to the number of tires used and disposed of irregularly and the risk this poses to health and the environment, it is necessary to ensure that tires are preferably reused, recycled or refurbished prior to their correct subsequent disposal (Conama, 2009). Resolution No. 416, of September 30, 2009, sets out guidelines on the final destination of tires and on the need to take care of the environmental degradation that REVISTA OBSERVATORIO DE LA ECONOMIA LATINOAMERICANA ISSN: 1696-8352 Page 16 REVISTA OBSERVATORIO DE LA ECONOMIA LATINOAMERICANA, Curitiba, v.23, n.3, p. 01-45. 2025. the time frame covered by this study.

Source: Based on the Play Fair Program, 2013; Sinir, 2015; MMA, 2013b; MMA, 2013c; Antt, 2004; Conama, 2005; Conama, 2009 and Inpev, 2016. The OLUC sector agreement provided for its termination by the year 2016. Due to this, considering the time frame covered by this research (years 2015/2016), the quantities were forwarded through the Product Movement Information System. ( SIMP), which received the waste and was responsible for this system (ANP, 2017). 2.4.3 Number of collection points Due to its peculiarities, each System adopted a way of defining the number of collection points (Play Clean Program, 2013; Sinir, 2015; MMA, 2013b; MMA, 2013c; Antt, 2004; Conama, 2005; Conama, 2009 and Inpev, 2016). Each system has its own requirements when it comes to receiving waste. For example, it is worth highlighting the collection points for lubricating oil packaging, which only accept packaging up to one liter (Sinir, 2012). Batteries and batteries receive up to 30 kg; for unusable tires, they receive 2,000 units of passenger tires and 300 units of truck tires. Table 4 presents a summary of the information available about each System, in the time period covered by this study. REVISTA OBSERVATORIO DE LA ECONOMIA LATINOAMERICANA ISSN: 1696-8352 Page 17 REVISTA OBSERVATORIO DE LA ECONOMIA LATINOAMERICANA, Curitiba, v.23, n.3, p. 01-45. 2025. Table 4.

The definition of collection points for medicines and electronics - at the time - was similar, taking into account the number of households in the municipality, the amount of medicines/electronics entering the market, the annual discard rate, the number of individuals and population density (MMA, 2013b, 2013c). The light bulb delivery network also takes into account some city data. The municipality must have at least 250 inhabitants/km²; for municipalities with a population greater than 25,000 inhabitants, with an average interval of 4 km between each monitored residence, there is a fixed collection point (Sinir, 2018d). The OLUC system used the SIMP system for monthly collection. Companies sent products to the program (Simp, 2017). In 2014, Lubricating Oil Packaging had collection points in 2,300 municipalities and the goal was to reach 100% of the municipalities in the Southeast, South and Northeast regions (except Piauí and Maranhão) by 2016 (Sinir, 2012; Sindicom, 2014). 2.4.4 Quantities to be returned Each system has a different way of accounting for the amounts it expects to receive and how much was actually collected. This is because each one has peculiarities that need to be considered (Play Clean Program, 2013; Sinir, 2015; MMA, 2013b; MMA, 2013c; Antt, 2004; Conama, 2005; Conama, 2009 and Inpev, 2016). Table 5 presents a summary of the information available about each System, in REVISTA OBSERVATORIO DE LA ECONOMIA LATINOAMERICANA ISSN: 1696-8352 Page 18 REVISTA OBSERVATORIO DE LA ECONOMIA LATINOAMERICANA, Curitiba, v.23, n.3, p. 01-45. 2025. the time period covered by this study.

The estimate for electronic products would only be established after the signing of the sectoral agreement. The General Packaging system had the goal of reducing 22% of packaging in landfills by 2018 (Sinir, 2015). OLUC collectors needed to collect at least 30% of the volume placed on the market within a year (Conama, 2005). The target for lubricating oil packaging was to collect 4,400 tons by 2016 (Sinir, 2012). For lamps, the sectoral agreement envisaged a collection of 20% of the lamps placed on the market five years after the signing of the agreement (Sinir, 2018d). 2.5 AHP – ANALYTICAL HIERARCHICAL PROCESS The AHP (Analytic Hierarchy Process) tool was developed by Tomas L. Saaty in the 1980s. It is a method used for decision-making. It is the best-known multicriteria methodology used in business conflicts and problems with multiple criteria (Marins; Souza; Barros, 2009). When a decision is made, it is expected to have chosen the option that presents the greatest performance and the best option among those presented (Marins; Souza; Barros, REVISTA OBSERVATORIO DE LA ECONOMIA LATINOAMERICANA ISSN: 1696-8352 Page 19 REVISTA OBSERVATORIO DE LA ECONOMIA LATINOAMERICANA, Curitiba, v.23, n.3, p. 01-45. 2025. 2009). Its main aspect is to guide the intuitive processes of choosing options, in order to make the correct decision. This tool characterizes, classifies and prioritizes the information necessary to reach the best final solution (Oliveira; Belderrain, 2008). According to Costa (2002), Favretto and Nottar (2016), the AHP method is based on three analytical stages, namely: Construction of the hierarchy; Definition of priorities and Assessment of consistency. Hierarchical construction begins when there is a problem that needs to be solved, which is then located in the first line of the hierarchical tree. To solve this problem, some criteria are defined that are relevant when choosing the best options for solving the problem. If the problem is very complicated, sub-criteria can be used to obtain an even more precise solution (Costa, 2002). Figure 1 illustrates a basic hierarchical structure. Figure 1. Basic hierarchical structure Source: Adapted from Marins, Souza and Barros, 2009. When defining priorities, the elements are compared equally and it is at this moment that the person judging the elements must perceive the similarity between the objects studied, in order to then assemble the AHP comparison matrix. For this, the numerical scale developed by Saaty is used, which helps when characterizing the elements (Marins; Souza; Barros, 2009). Table 6 presents the scale developed by Saaty. REVISTA OBSERVATORIO DE LA ECONOMIA LATINOAMERICANA ISSN: 1696-8352 Page 20 REVISTA OBSERVATORIO DE LA ECONOMIA LATINOAMERICANA, Curitiba, v.23, n.3, p. 01-45. 2025. Table 6. Numerical scale developed by Saaty NUMERICA L SCALE CONCEPTUAL SCALE DESCRIPTION 1 Equal Both elements contribute equally to the objective 3 Moderate The compared element is slightly important in relation to the other 5 Strong Experience and judgment strongly favor one element over the other 7 Very strong The compared element is much stronger in relation to the other, and such importance can be observed in practice 9 Absolute The compared element presents the highest possible level of evidence in its favor 2, 4, 6, 8 Intermediate values between two judgments, used when the decision maker finds it difficult to choose between two adjacent degrees of importance Source: Based on Ribeiro and Alves, 2016. To define the AHP matrix, it is necessary to meet the following conditions: Table 7. Conditions for Assembling the AHP Matrix CONDITIONS FOR ASSEMBLY OF THE AHP MATRIX (i) Condense information - in the time frame of 2015/2016 - referring to the nine Reverse Logistics Systems addressed (Unusable tires; Agrochemical packaging; Used or contaminated lubricating oil; Batteries; Plastic packaging for lubricating oils; Sodium and mercury vapor fluorescent lamps and mixed light; Packaging in general; Electronic products and their components; Medicines), regarding four analysis topics (Reverse flows practiced; Intended objectives and goals; Number of collection points; Quantities of products to be returned by the systems); (ii) Suggest performance indicators for each of the four topics analyzed; (iii) Using an analytical hierarchical process (AHP) tool, designate a way of assessing the performance of these systems, in order to classify them considering the established criteria.

CR = CI 𝑅𝐼 (1) where : CR = Degree of Consistency CI = Consistency Index RI = Random Consistency Index The Random Consistency Index is tabulated by Saaty, as shown in Table 8. REVISTA OBSERVATORIO DE LA ECONOMIA LATINOAMERICANA ISSN: 1696-8352 Page 21 REVISTA OBSERVATORIO DE LA ECONOMIA LATINOAMERICANA, Curitiba, v.23, n.3, p. 01-45. 2025. Table 8 .

The Consistency Index is calculated using Formula 2 (Trevizano; Freitas, 2005). CI = λ max − 𝑛 𝑛−1 (2) where : CI = Consistency Index λ max = Largest eigenvalue of the judgment matrix n = Number of items that are compared In this research, the AHP method was used to hierarchize the Reverse Logistics Systems, considering, for this purpose, performance indicators related to each of the four analysis points initially presented in topic 2.4 of this article. 3 METHODOLOGY This work was structured based on the ontological approach of the theme, which was established through data collection in periodicals, websites and books. Three main objectives were established to carry out this research: (i) Condense information - in the time frame of 2015/2016 - referring to the nine Reverse Logistics Systems addressed (Unusable tires; Agrochemical packaging; Used or contaminated lubricating oil - Oluc; Batteries; Plastic packaging of lubricating oils; Sodium and mercury vapor fluorescent lamps and mixed light; Packaging in general; Electronic products and their components; Medicines), regarding four analysis topics (Reverse Flows practiced; Intended Objectives and REVISTA OBSERVATORIO DE LA ECONOMIA LATINOAMERICANA ISSN: 1696-8352 Page 22 REVISTA OBSERVATORIO DE LA ECONOMIA LATINOAMERICANA, Curitiba, v.23, n.3, p. 01-45. 2025. Goals; Number of collection points; Quantities of products to be returned by the Systems); (ii) Suggest performance indicators for each of the four topics analyzed; (iii) Using an analytical hierarchical process tool (AHP - Analytic Hierarchy Process ), designate a way of assessing the performance of these Systems, in order to classify them considering the established criteria. To meet the proposed objectives, the sequence of actions was as shown in Table 9. Table 9.

After the bibliographic survey involving the nine Brazilian Reverse Logistics Systems with national coverage - in the 2015/2016 time frame - focusing on the four topics of interest of the research (Reverse flows, Objectives and goals, Number of collection points and Quantities of products to be returned by the Systems), the fundamentals of the AHP method were presented, in order to support the structuring for the intended comparison. To achieve this objective, it was necessary to establish an indicator that would represent, in a relevant way, each of the topics of interest addressed, which would be suitable as a parameter for comparison between the Systems. Thus, an AHP Hierarchical Tree was created, composed of the nine Reverse Logistics Systems researched and the four representative indicators for the analysis (Number of collection points, 2015/2016 Goals, Number of stages and Quantities REVISTA OBSERVATORIO DE LA ECONOMIA LATINOAMERICANA ISSN: 1696-8352 Page 23 REVISTA OBSERVATORIO DE LA ECONOMIA LATINOAMERICANA, Curitiba, v.23, n.3, p. 01-45. 2025. returned), which are presented below. The time frame of this research between the years 2015/2016 implies considerations regarding each of the nine Reverse Logistics Systems at the time, as shown in Table 10. Table 10. 2015/2016 time frame of the five post-PNRS sectoral agreements considered in this research Reverse Logistics Systems Implementation stage of each Sectoral Agreement in the 2015/2016 time frame Plastic Lubricating Oil Packaging Sectoral Agreement signed on December 19, 2012 and published on February 7, 2013 Lamps Sectoral Agreement signed on 27 November 2014 and published on 12 March 2015 Electronics Ten proposals for Sectoral Agreements received by June 2013, four of which were considered valid for negotiation.

In this context, considerations should be given to the proposed Reverse Logistics Systems for Electronic Devices and Medicines (both with Sector Agreements still under negotiation in the 2015/2016 time frame): in general, Sector Agreements began to be discussed after the National Solid Waste Policy, but not all of them had proposals presented immediately. The programs presented - in Table 10 - under negotiation are those that had proposals launched late and, because of this, took a long time to be put into practice (Sinir, 2018d). The justification for the time frame of 2015/2016 is to bring to the reader's attention some intermediate phases that today's consolidated Reverse Logistics Systems needed to meet in order to obtain their Sector Agreements; and, at the same time, to attest to the reader about the possibility of applying the AHP method - as proposed in this article - in the comparison of Systems with different degrees of maturity and performance.

The following is an explanation of how the indicators were measured: Number of Collection Points: to decide the number of collection points spread throughout the country, the medicine, electronics and light bulb systems use the number of inhabitants as a parameter, that is, they set a maximum number of inhabitants for each REVISTA OBSERVATORIO DE LA ECONOMIA LATINOAMERICANA ISSN: 1696-8352 Page 25 REVISTA OBSERVATORIO DE LA ECONOMIA LATINOAMERICANA, Curitiba, v.23, n.3, p. 01-45. 2025. collection point. Due to this, the number of inhabitants in Brazil in 2016 was used to create this indicator. The number of collection points for each system in 2016 was used and divided by the number of inhabitants in the country, forming the collection points indicator. The territorial extension of Brazil was not used, as there are many uninhabited regions and with these values the indicator would not be relevant. Formula 3 shows the data used to create the indicator. PC = NPC HAB (3) where : PC = Collection Point Indicator NPC = Number of Collection Points HAB = Number of Inhabitants in Brazil 2015 and 2016 targets: when the sectoral agreements are signed, collection targets are defined for all systems. The systems have a period of time with targets, which are then reviewed and reformulated. To measure these targets, an indicator was formulated, dividing the 2015 targets by the 2016 targets. The relevance of this indicator is to highlight how the targets were developed. Some of these, as can be seen in Table 3, decreased instead of increasing. This occurred due to some problems encountered during the course of the projects. The following is formula 4, which was used to develop the indicator. IM = M2015 M2016 (4) where : IM = Target Indicator M2015 = Goals for the Year 2015 M2016 = Goals for the Year 2016 REVISTA OBSERVATORIO DE LA ECONOMIA LATINOAMERICANA ISSN: 1696-8352 Page 32 REVISTA OBSERVATORIO DE LA ECONOMIA LATINOAMERICANA, Curitiba, v.23, n.3, p. 01-45. 2025.

To compare the best system, the weight of the indicator criteria was used and multiplied by the normalized autovector. After that, each line was added together, and the best overall system was obtained.

Initiatives from everyone are needed so that Reverse Logistics of materials can be further developed, and so that these materials are no longer discarded in inappropriate places. There are sectoral policies and agreements that govern the progress of these programs and what should or should not be done in each case. The companies that supply these inputs are responsible for their collection, and may be fined if they do not do so. Because of this, a large part of these materials are being disposed of correctly and thus causing less harm to the environment. The collaboration of consumers of these materials is also necessary, because after use they must be sent to collection points where they will be collected by the responsible companies. Comparing all systems under the indicator Number of collection points , it was found that: the Agrochemical Packaging system had a poor performance in relation to the number of collection points, which was expected, since there were not many collection points for this waste; the Waste Tire system had a low number of collection points, leaving its performance lacking in this indicator. Batteries and Accumulators had a large number of collection points, this happened due to initiatives of companies that placed collection points for batteries and accumulators in their local businesses, thus increasing the number of collection points of this system. OLUC was the least favored system under this indicator, due to the few legalized and recognized collection points. Plastic Packaging of Lubricating Oil was the system that had the largest number of collection points, since gas stations are available to collect this waste; when there is an oil change at the gas station, the packaging is redirected to the correct location. Packaging in general had a high performance in relation to the number of collection points, since these are commonly used materials and many already recycle and separate them before removing this waste from their homes. The Lamps and Electronics systems were relatively new in the time frame of this research and did not yet have many collection points spread throughout the country, as well as the Medication system , which had the support of pharmacy chains that collected discarded medications.

Based on the data obtained by the AHP matrix and with the consistency index demonstrating that the data are acceptable, it was possible to assemble Figure 9, showing the ranking of the systems in relation to the indicator of the number of collection points. Figure 9 . Best System in Relation to Number of Collection Points Source: Own authorship. Regarding the 2015/2016 Targets indicator , Pesticide Packaging and Waste Tires were the systems that performed best in defining targets from one year to the next, demonstrating an increase in objectives. Medications , General Packaging , Light Bulbs and Batteries demonstrated low performance, each presenting only 2.54% of the total, which shows that these systems did not define more ambitious targets when establishing the systems. When assembling the indicator, the value zero was used for systems that did not have targets , this was done to demonstrate that systems that do not define targets are disadvantaged in relation to the others.

Figure 10 . Best System Regarding Goals 2015/2016 Source: Own authorship. Regarding the Returned Amounts indicator , the system that collected the most waste in 2016 was OLUC , even with the small number of collection points. This occurred because this system managed to exceed the target set for 2016, thus being the best system in this comparison criterion. General Packaging and Electronics demonstrated good results, but were unable to reach the targets, but came very close to the expected result, as shown in Figure 11. 27,62% 21,64% 6,56% 2,54% 22,25% 2,54% 2,54% 11,76% 2,54% EMBALAGENS DE AGROTÓXICOS PNEUS INSERVÍVEIS OLUC PILHAS E BATERIAS EMBALAGENS PLÁSTICAS DE ÓLEO LUBRIFICANTE LÂMPADAS EMBALAGENS EM GERAL ELETROELETRÔNICOS MEDICAMENTOS Goals 2015/2016 REVISTA OBSERVATORIO DE LA ECONOMIA LATINOAMERICANA ISSN: 1696-8352 Page 36 REVISTA OBSERVATORIO DE LA ECONOMIA LATINOAMERICANA, Curitiba, v.23, n.3, p. 01-45. 2025. Figure 11 . Best System Regarding the Amount of Waste Returned Source: Own authorship. The Medicines , Lamps , Batteries and Plastic Packaging for Lubricating Oil systems had a very low performance in this indicator, this occurred due to the fact that they were unable to achieve the goals established for the year 2016 and, in the case of the first three systems mentioned, they were relatively new systems in the time frame of this research, which did not have defined goals yet and, in the assembly of the indicators, the systems without goals were defined as inferior systems when compared to others. Number of steps indicator, Pesticide Packaging showed growth in relation to the other systems, being the second best system in relation to this indicator. The best system in this indicator was the General Packaging system , as it has simpler disposal and fewer steps when returning the waste. In the case of the Plastic Lubricating Oil Packaging System , its number of steps was high, for its correct recycling several steps would be necessary, due to the need to decontaminate the packaging. Light bulbs and Batteries were the least favored in this indicator, this happened because this waste is composed of several components and needs to be separated and destined for the correct destination, not being possible to recycle this waste completely. Medications also showed a low performance evaluation, because at the time of its reverse logistics, it would need to separate the tablets from the ointments and syrups, making the process more complex. The performance of the systems is shown in Figure 12. 6,96% 3,02% 36,05% 3,02% 3,02% 3,02% 20,94% 20,94% 3,02% EMBALAGENS DE AGROTÓXICOS PNEUS INSERVÍVEIS OLUC PILHAS E BATERIAS EMBALAGENS PLÁSTICAS DE ÓLEO LUBRIFICANTE LÂMPADAS EMBALAGENS EM GERAL ELETROELETRÔNICOS MEDICAMENTOS Quantity of Waste Returned REVISTA OBSERVATORIO DE LA ECONOMIA LATINOAMERICANA ISSN: 1696-8352 Page 37 REVISTA OBSERVATORIO DE LA ECONOMIA LATINOAMERICANA, Curitiba, v.23, n.3, p. 01-45. 2025. Figure 12 . Best System Regarding Number of Steps Source: Own authorship. The comparisons made it possible to rank all the systems in general. In this case, the General Packaging plan stood out the most, and was the system that performed best in relation to the listed indicators. Of the four indicators used, it performed well in three of them, but only in the target category did it perform poorly. The project can still be improved by providing more collection points and raising awareness among the entire population about the importance of separating waste in their daily lives. With everyone separating waste, waste collection becomes much easier and more waste will be disposed of correctly.

The systems that were in operation in the country at the time were: Agrochemical Packaging, Unusable Tires, OLUC, Batteries, Plastic Packaging for Lubricating Oil, Lamps, Packaging in General, Electronics and Medicines, the first four being implemented before the National Solid Waste Policy. The purpose of this comparison was to rank the systems in general, according to suggested performance criteria, comparing all indicators and also how each system would be developing in each topic. These results provide support for redoubling efforts in specific topics, in order to improve the Reverse Logistics Systems currently implemented. The Packaging in general system was ranked as the best overall system, because among all the Reverse Logistics Systems examined, it suggests less complexity in its operation, since Packaging in general is used in everyone's daily lives and the consumer population is increasingly aware of the need to separate this waste from organic waste, which ends up facilitating the correct return of this waste.

Despite some difficulties, this system stood out among the other systems, but there are still points for improvement, such as increasing the targets for the return of waste; it was the only indicator in which it did not show a better performance. Regarding the number of collection points, at the time of the data research, it was already possible to predict this impact, as the number of collection points for plastic packaging of lubricating oils was much higher than those of other systems. Thus, there was a performance of 37% in this indicator. The best system was the one with the fewest steps, showing that materials can be disposed of more quickly. The Packaging system in general stood out in this indicator, because when this material was sent to collection points, it was already separated in most cases, thus reducing the number of steps for the subsequent disposal of this waste. The systems with the least satisfaction were Light Bulbs and Batteries, this was due to the fact that these are materials that contain compounds that are harmful to the environment and must be separated. The number of items returned took into account the goals for 2016 and the amount returned in that same year, showing which system achieved the expected results and how much more waste was collected. OLUC collected the largest amount of used and contaminated lubricating oil, with a performance of 36%. Of all the indexes, this is considered the most important, as it allows us to learn a little more about the return of waste, showing which ones reached the target, which ones did not, and which ones exceeded it. If some systems were managing to exceed the target for returned items, it suggested that they were working well. Even though there were few collection stations at the time, many gas stations volunteered to join this system, reserving this oil in a suitable location. The 2015/2016 Goals indicator was determined with the aim of demonstrating the goals set for the progress of the project. The goals should always be higher than those of previous years, to demonstrate that the system was continually improving. The system that demonstrated the best development was Plastic Packaging for Lubricating Oil, with its 2016 goal being much higher than that of 2015, showing that good performance was REVISTA OBSERVATORIO DE LA ECONOMIA LATINOAMERICANA ISSN: 1696-8352 Page 40 REVISTA OBSERVATORIO DE LA ECONOMIA LATINOAMERICANA, Curitiba, v.23, n.3, p. 01-45. 2025. expected from the system. The systems that were harmed were the most recent ones, which did not have goals for 2015. Therefore, this research achieved its objectives by providing support for improvements in the Reverse Logistics systems implemented in Brazil during the period considered, suggesting points of attention for analyzing the performance of these systems. The justification for the time frame of 2015/2016 is to bring to the reader's attention some intermediate phases that today's consolidated Reverse Logistics Systems needed to meet in order to obtain their Sector Agreements; and, at the same time, to attest to the reader about the possibility of applying the AHP method - as proposed in this article - in the comparison of Systems with different degrees of maturity and performance. By presenting step by step the entire methodology used, including the composition of the proposed indicators, this research aims to encourage future work involving the development of new indicators to aid decision-making, to improve the performance of Reverse Logistics Systems.
