“…S2). This growth is equivalent to a 1.4 to 2.8% average annual growth from 2020 to 2050, consistent with the World Bank's projected global average annual growth of 2.4% (19). Considering the uncertainty in modeling GHG emissions, we applied an ensemble forecasting technique using an artificial neural network coupled with Bayesian hyperparameter optimization (20).…”

No global analysis has considered the warming that could be averted through improved solid waste management and how much that could contribute to meeting the Paris Agreement’s 1.5° and 2°C pathway goals or the terms of the Global Methane Pledge. With our estimated global solid waste generation of 2.56 to 3.33 billion tonnes by 2050, implementing abrupt technical and behavioral changes could result in a net-zero warming solid waste system relative to 2020, leading to 11 to 27 billion tonnes of carbon dioxide warming–equivalent emissions under the temperature limits. These changes, however, require accelerated adoption within 9 to 17 years (by 2033 to 2041) to align with the Global Methane Pledge. Rapidly reducing methane, carbon dioxide, and nitrous oxide emissions is necessary to maximize the short-term climate benefits and stop the ongoing temperature rise.

“…A taxa de geração da FORSU varia em razão de fatores culturais, nível de desenvolvimento econômico e hábitos de consumo. As taxas de geração per capita nos países ditos 'desenvolvidos' é muito maior do que nos países economicamente menos prósperos (KAZA et al, 2021). No mais, enquanto a FORSU representa em média 30% dos RSU gerados nos países de maior renda, sendo superada pela geração de resíduos como papel e plástico, nos países de menor renda a FORSU representa de 50% a 60% do total gerado (WILSON et al, 2015;KAZA et al, 2018), conforme verificado na Tabela 2.…”

Factors such as urbanization contribute to the constant increase in the generation of municipal solid waste, of which the organic fraction is the most significant. Composting is a versatile and scalable alternative for managing organic waste, and European countries have been intensifying the adoption of this strategy, both centrally and decentrally. On the other hand, the management of the Organic Fraction of Municipal Solid Waste (OFMSW) in Brazil, with the exception of unsuccessful experiments with centralized composting systems, is limited to disposal in landfills or dumps, rendering recoverable organic material useless and generating significant emissions of methane, one of the main greenhouse gases. Studies addressing decentralized composting as a strategy to improve waste management are still infrequent in Brazil. In this context, this article aimed to outline an overview of the generation of OFMSW in the world and in Brazil, as well as initiatives for its proper management. Based on a literature review, it compares the management of OFMSW in Europe and Brazil, and points out perspectives from the current Brazilian regulatory framework. Then, it discusses the potential benefits and challenges in implementing and operating decentralized systems. Decentralized composting (community or domestic) is a low-cost alternative for the management of OFMSW, but requires citizen engagement, in addition to attention to the quality of the final products. Future studies should address the positive impacts and possible restrictions of this alternative in Brazilian contexts, contributing to enable its integration into the management models currently adopted in the country.

“…According to the most recent World Bank report, waste generation is estimated to grow from 2.24 billion tons in 2020 to 3.88 billion tons in 2050 [1] given the relation between economic growth and waste production. In the European Union (EU), between 2010 and 2020, waste generation decreased slightly, with the total annual waste generation per capita reducing from 5.0 to 4.8 tons/capita.…”

The environmental Kuznets curve has received widespread attention from scholars for its ability to vividly capture the dynamics between economic growth and waste generation. The so-called waste Kuznets curve (KWC) has been used in different fields (e.g., municipal waste, e-waste, construction waste, tourism waste, etc.); nonetheless, WKC studies into agricultural waste remain relatively scarce. Due to the impact of agriculture on socio-economic development and environmental protection, this study applied KWC to the Italian agricultural sector. The aim was to investigate whether a “decoupling effect” exists between agricultural production and waste generation and assess the effects of certain socio-economic variables. The analysis was based on a panel dataset, including geographical observations at a regional level and a time series of 14 years (2002–2015). Empirical results show that the delinking point has not yet been reached, but can be reached if specific policy instruments are applied. Our evidence suggests that public expenditure for environmental protection or the promotion of organic farming could help to achieve this goal. Future studies are recommended to further validate the waste Kuznets curve for agriculture using a wider set of economies and longer panel data.
