This article aims to identify and comprehend the challenges and strengths behind public policies on integrating waste pickers (WPs) within waste management systems in Colombia and Brazil. In both, WPs started to come together and found organisations and external agents such as NGOs began to support organised groups of WPs. After 10 years of judicial court actions in Colombia, WPs organisations were finally recognised in legislation, while in Brazil, they were recognised in 2007 in one of the national policies through lobby. Today, there are almost 700 WPs organisations formalised in Colombia and 1700 in Brazil. Their public policies’ main achievements and challenges are exposed to supply knowledge to other countries interested in this theme. A Roadmap for the organisation and formalisation of WPs within waste management systems was created. This constitutes a source of information for policymakers in other emerging economies to address this in their territories.

Resumo O objetivo do trabalho consistiu em analisar o comprometimento ambiental na Faculdade de Engenharia Civil, Arquitetura e Urbanismo (FEC), através da separação de recicláveis. Para identificar o fluxo de materiais recicláveis gerados na FEC foi realizada uma visita à Diretoria de Limpeza Urbana (DLU), responsável pela gestão de resíduos sólidos dentro do Campus da Unicamp. A caracterização dos materiais recicláveis foi feita através do estudo da composição gravimétrica dos mesmos. Os resultados mostram a presença de uma grande parcela de rejeitos e materiais orgânicos misturados com os materiais recicláveis, apresentando uma falta de comprometimento de estudantes e colaboradores com a segregação dos resíduos gerados.

Currently, countries worldwide are debating their strategies to achieve net-zero emissions by 2050. The International Energy Agency (IEA) has called energy efficiency (EE) the “first fuel,” the most cost-effective way to reverse this unprecedented challenge and provide significant benefits to society. In this sense, a proposal for the Brazilian Ten Years Energy Efficiency Plan (PDEf) was launched in 2020, which brings actions and goals for the year 2030 on EE at federal government level, aiming to generate lower energy intensities in the country. Looking to establish a further disaggregation level of the energy conservation policies portfolio, this paper intends to go to the state government level, taking the state of São Paulo as a case study. The aim is to make projections of electricity and fuel savings in relevant sectors for the year 2030 and propose adjustments in public policies. As results, electricity savings of 11,171.46 GWh and fuel savings of 7,486.74 ktoe are expected by 2030. These values represent 5,1% of the electric energy consumption and 11% of the fuel consumption projected for São Paulo in 2030.
