In 2001, Argentina suffered an economic collapse that almost wiped out the middle-class, leaving thousands homeless. This resulted in the growth of the informal settlements and informal sectors of employment in and around the formal city of Buenos Aires, the “Capital Federal.” The urgency for survival led to the rise of many waste-pickers or, as they became known the cartoneros. Today they are the primary recycling program in the city with many cooperatives helping their movement. The city has enforced a ‘zero waste’ policy for 2020 in dealing with their serious trash problem and the cartoneros will play a large role in this transformation. This thesis aims to address two complex social issues (disparity and waste) with a long-term architectural initiative which hopes to ultimately blur the social boundaries that exist in the “Paris of the South” via the cartoneros.

The generation of solid waste is a natural consequence of human life. Its rate has increase rapidly along the years, mostly due to the population growth, urbanization process coupled to industrialization and economic development. The uncontrolled disposal of solid waste in unsuitable sites, dump sites, has poses a threat to public health and the environment. In this regard Global efforts has been made to rethink municipal solid waste management toward sustainability. Middle- and low-income countries, such as Brazil, should seize the opportunity and centre efforts in the development and strengthen of an inclusive municipal solid waste management, supported by an innovative public policy where all government levels are integrated and focused on resource recovery and recycling through the organization and strengthening of waste pickers, in order to act directly in the income improvement of a marginalized portion of society as a result of the revenue generated by recovered and recycled materials sales, as well as reduce the CO2eq emissions consequent from the disposal of solid waste, among others, hence moving these countries towards the achievement of the SDG goals. In this regard, a well managed inclusive municipal solid waste system requires a reliable data source to support decision makers in the design of public policies with effective actions in the field, otherwise innovative and modern public policies will be filled with fruitless actions, thus, wasting the aptitude of the municipal solid waste management system in help middle- and low-income countries to successfully carry out the SDGs goals. Nevertheless, the estimation methods are a valuable tool for decision makers in middle- and low income countries to outrun the lack of solid waste information and doing so, increase the effectiveness of public polices towards a sustainable and inclusive municipal solid waste system, focused on mitigate negative impacts in the environmental sphere and potentiate the positive outcomes in the public health and human development sphere in these countries. This research proposed an estimate method based on the nominal income which is able to provide a reliable estimate of the residential solid waste generation, as well as its spatial distribution in the municipal level and within the municipal boundaries. The proposed approach has the ability to differentiate spatial distribution of the residential solid waste generation, weighting not just the number of people living in a determined space, but also the purchase power of those people, providing a more accurate view of the issue, which benefits decision makers to design and plan their polices and actions. / Graduate

Garantir tratamento e disposição final adequada para os resíduos sólidos urbanos é um desafio para as administrações municipais, principalmente porque a geração de resíduos tem aumentado à taxa maior do que a de aumento da população e as grandes áreas para construção de aterros sanitários são escassas nas grandes cidades. Assim, desde o final da década de 1980, no Brasil, alguns municípios têm implementado programas de coleta seletiva de resíduos sólidos urbanos em parceria com organizações de catadores, que desviam resíduos da disposição em aterros sanitários, aumentando sua vida útil. Torna-se importante olhar para os programas de coleta seletiva como parte de políticas públicas, enfatizando sua continuidade administrativa e seus objetivos. Nesse sentido, buscou-se estudar o programa de coleta seletiva de Santo André SP, entre os anos de 1998 e 2011. O objetivo é estudar como se deram a elaboração e a implementação do programa de coleta seletiva do município de Santo André, em 1998, e como vem sendo feito seu monitoramento e avaliação nos anos posteriores, até o ano de 2011. Para isso foi utilizada a abordagem de policy cycle, que considera a política pública como um ciclo deliberativo, constituído por vários estágios, formando um processo dinâmico e de aprendizagem. Foi realizada pesquisa bibliográfica e documental, bem como entrevistas qualitativas semi-estruturadas com: representantes do Serviço Municipal de Saneamento Ambiental de Santo André (Semasa); os coordenadores administrativos das duas cooperativas parceiras do programa (Coopcicla e Coop Cidade Limpa) e uma amostra randômica de seis cooperados de cada uma das cooperativas parceiras do programa. Após as entrevistas, houve aplicação de questionários a todos os catadores da Coopcicla e Coop Cidade Limpa, totalizando 79 cooperados. Além disso, foram realizadas visitas técnicas com registros escritos e fotográficos aos equipamentos públicos: estação de coleta, usina de triagem e reciclagem de papel, centrais de triagem de materiais recicláveis, usina de reciclagem de madeira. Foi possível constatar que o programa de coleta seletiva foi elaborado com objetivo de atender toda a população urbana do município; em seguida, foi implementado, colocando-se em prática as ações planejadas, mas até o momento não há ações de monitoramento e avaliação do programa, que poderiam produzir aprendizagem administrativa. Em relação às cooperativas, a parceria com o Semasa é instável, o número de catadores vem diminuindo e não há ações para enfrentar coletas paralelas de materiais recicláveis. Por outro lado, as cooperativas garantem aos catadores renda maior que em suas ocupações anteriores, estabilidade e inclusão. Como conclusão, não pode ser considerado satisfatório que um programa municipal de coleta seletiva que existe há mais de 10 anos, dispõe de coleta porta a porta em 100% de sua área urbana, pontos de entrega voluntária, estações de coleta seletiva consiga desviar menos de 3% dos resíduos sólidos urbanos do aterro sanitário. Nesse sentido, faz-se necessário mudar o paradigma: ter coleta seletiva não significa só oferecer o serviço; é necessário coletar seletivamente, com a participação dos munícipes. / Guaranteeing treatment and appropriate disposal to municipal solid waste is a challenge to municipal administrations, mainly because waste generation has increased more than population and big areas to landfills are few in big cities. Thus, since last 1980, in Brazil, a few cities have implemented municipal programs of selective waste collection in partnership with waste pickers organizations, that remove waste from landfills, increasing your lifetime. It is important to look at programs of selective waste collection as part of policy, emphasizing your administrative continuity and objectives. Therein it was sought to study Santo Andrés program of selective waste collection, between 1998 and 2011. The objective is to study how were formulation and implementation of Santo Andrés program of selective waste collection, in 1998, and how it has been making your monitoring and evaluation in the following years, until 1998. For this reason it was used policy cycle approach, that considers policy as a deliberative cycle, formed by several steps, constituting a dynamic and learning process. It was made bibliographical and documental research, such as qualitative semi-structured interviews with: managers of Serviço Municipal de Saneamento Ambiental de Santo André (Semasa); managers of two partner cooperatives of program (Coopcicla and Coop Cidade Limpa) and a random sample of six members of each cooperative. After the interviews, it was made questionnaire application to all waste pickers of Coopcicla and Coop Cidade Limpa, totalizing 79 members. In addiction, it was made technical visits with written and photographic records to public equipment: collect station, paper selection and recycling plant, recyclables selection centers, wood recycling plant. It was possible to notice that program of selective waste collection was formulated with the objective to cover all urban population; it was implemented, putting planned actions into practice, but there are not monitoring and evaluation, that would produce administrative learning. Concerning cooperatives, the partnership with Semasa is not steady, members of cooperatives number has decreased and there are not actions to face parallels recyclables collects. In the other hand, the cooperatives guarantee to your members bigger income than in former occupations, stability and inclusion. As a conclusion, it is not satisfactory that a municipal program of selective waste collection that exists for more than 10 years, has door to door selective waste collection in 100% of urban area, collect stations is able to remove less than 3% of municipal solid waste from landfill. Therein it is necessary to change the paradigm: selective collection does not mean to offer the service; it is necessary to collect in a selective way, with people participation.

This project is a study of the wastescape - a network of waste - of Bhubaneswar and Cuttack in Odisha, India.  The study incorporates key locations, e.g. landfills, urban wastelands and waste warehouses; major actors in the formal and informal waste sector; and flows of waste through economic and social systems. Drawing from the studies, multiple interventions within the wastescape are proposed for improvement of the economic, ecologic and social situation. An important aspect of the project is the development of an approach for how to, as architects, work with big, complex, contingent networks; how to map and understand such a system; and how to determine where to intervene. To improve the existing wastescape, interventions must consciously and holistically address multiple scales; levels of formal-informal; and phases within the waste cycle. The study includes a vast amount of possible interventions. Some of the interventions are further detailed to show feasibility; impact on the wastescape; and synergies with other interventions within the wastescape. / Projektet “Wastescape of Bhubaneswar & Cuttack” är en studie av ett nätverk av skräpflöden genom Bhubaneswar och Cuttack i Odisha, Indien. Studien inkorporerar viktiga platser, t.ex. deponier, urbana ödemarker och lokaler för skräphandel; stora aktörer i den formella och informella skräpsektorn; och flöden av skräp genom ekonomiska och sociala system. Utifrån dessa studier, ett flertal interventioner i “the wastescape” föreslås för att förbättra den ekonomiska, ekologiska och sociala situationen. En viktig aspekt av arbetet är utvecklingen av ett sätt att, som arkitekt, arbeta med storskaliga, komplexa och inter-beroende nätverk; hur sådana system kan kartläggas och förstås; samt hur det går att avgöra vart och hur interventioner passar in i “the wastescape”. För att förbättra “the wastescape”, interventioner måste medvetet och holistiskt adressera multipla skalor; nivåer av formell-informell; och faser i skräpets kretslopp. Studien innehåller ett stort nummer av möjliga interventioner. Några av dessa interventioner är ytterligare detaljerade för att visa på genomförbarhet; påverkan på “the wastescape”; och synergier gentemot andra interventioner i “the wastescape”.
