Fertilizers are essential inputs for the agribusiness chain—they increase the productivity on available arable land and help to avoid changes in land use. Currently, Brazil is one of the largest consumers of fertilizers in the world but its imports of NPK fertilizers, as a percentage of its total consumption, have risen from 32% in 1988 to 77% in 2018. Biofuels are relevant in the transport sector and the Brazilian government, after the Paris Agreement, created the National Biofuels Policy (Renovabio), which has as one of its goals to raise the participation of biofuels in the transport sector to 28.6% by 2028. Soy, corn, and sugarcane (biofuels raw material) currently account for more than 70% of the consumption of NPK fertilizers in the country. Due to several reasons, in the last 10 years many local projects designed to fill the supply gap for fertilizers in Brazil have not been successful. The recent COVID-19 pandemic has raised questions about the reliability of fertilizer supply in global value chains. In this context, is Brazil’s long-term biofuel market at risk after COVID-19? A total of 38 experts were consulted and four reference scenarios were developed. The article concluded that the Brazilian fertilizer industry must be prepared for a scenario of limited increase in demand on a global scale—strategic alliances may be forged to maintain existing installed capacity. Should the Brazilian government fail to provide any stimulus for the country’s fertilizer industry, it is likely that by 2035, Brazil’s biofuel industry sector would be overexposed to price volatility and availability on the global fertilizer market.

The first Green Chemistry ACS Student Chapter has been founded in Brazil at the Federal University of Rio de Janeiro (UFRJ) so as to support outreach activities in Green Chemistry education such as experiments and didactic initiatives to secondary and undergraduate levels associated with sustainable agriculture and socio-environmental technologies. However, there is a lack of

Founded at the Federal University of Rio de Janeiro (Brazil), the ACS UFRJ Student Chapter is a volunteer college association dedicated to integrating both industrial and everyday life Green Chemistry perspectives within chemical education. Since 2017, the group has been conducting didactic initiatives and discussions focused on school communities and university engagement.

A publicação do novo marco legal do saneamento básico no Brasil – LEI Nº 14.026, de 15 de julho de 2020 definiu novos prazos iminentes para encerramento dos 3326 “lixões” e aterros controlados no território nacional. A importância do fim das atividades ou s adequação das áreas de disposição irregular de RSU é primordial para a eliminação/redução da contaminação dos compartimentos ambientais. Com as dificuldades financeiras e índices de avaliação de qualidade de áreas de disposição subjetivos – IQR (CETESB) e IQDR (INEA) pouco foi feito pelos gestores municipais nessas áreas. A fim de superar a subjetividade na utilização desses índices e direcionar ações efetivas, este trabalho propõe um novo Índice de Qualidade de Áreas de Disposição Irregular de RSU (IQUADI), baseada na Análise Hierárquica de Processo (AHP), definindo-se intervalos específicos para os critérios selecionados a partir de levantamento bibliográfico e documental. Os resultados finais mostram aos responsáveis pelos passivos ambientais se as atividades na área serão encerradas ou continuarão e quais medidas a serem adotadas. Verificaram-se divergências legais nos limites usualmente utilizados e novos limites foram propostos para os critérios componentes do IQUADI. A aplicação comparativa (estudo de caso) do IQUADI e do IQR no aterro controlado de Volta Redonda permitiu concluir que o IQR apresenta 58% de subjetividade para a seleção dos pesos de cada critério, ao contrário do IQUADI que apresentou valores específicos para cada intervalo selecionado integrante dos critérios. Subjectivity reduction in the MSW disposal areas classification through a new index applying Hierarchical Process Analysis: Quality Index of Irregular MSW Disposal Areas – IQUADIA B S T R A C TThe new legal framework publication for basic sanitation in Brazil in July 2020 defined new imminent deadlines for the closure of the 3326 “dumps” and controlled landfills in the national territory. The importance of the end of activities or the adequacy of MSW irregular disposal areas is essential for the elimination / reduction of contamination of environmental compartments. With the financial difficulties and the subjectivity of the quality assessment indexes of disposal areas - IQR (CETESB) and IQDR (INEA), little has been accomplished by municipal managers in these areas. In order to overcome the subjectivity in the use of these indices and direct effective actions, this work proposes a new Quality Index for MSW Irregular Disposal Areas (IQUADI), based on the Analytic Hierarchy Process (AHP), defining specific intervals for the selected criteria from a bibliographic and documentary survey. The final results show those responsible for environmental liabilities whether activities in the area will be closed or will continue and what measures must be performed. Legal differences have been identified in the limits usually used and new values were proposed for the criteria that compose IQUADI. The comparative application (case study) of IQUADI and IQR in the controlled landfill of Volta Redonda allowed us to conclude that the IQR presents 58% subjectivity for the selection of the weights of each criterion, in contrast to the IQUADI which presented specific values for each interval selected integral to the criterion.Keywords: municipal solid waste, closure, quality index, analytical hierarchy process.
