“…Segundo Kaza et al (2018), 2,01 bilhões de toneladas de RSU foram geradas globalmente em 2016 e, até 2050, esse valor será ampliado para 3,40 bilhões por ano. Os resíduos orgânicos corresponderam a 32-56% dos RSU, e as maiores frações remetem preponderantemente aos países de economia emergente (KAZA et al, 2018;FEHR et al, 2015;FEHR, 2014). A Figura 1 apresenta a geração de RSU e de resíduo orgânico em alguns países.…”

RESUMO Os resíduos orgânicos representam fração considerável dos resíduos sólidos urbanos gerados mundialmente. A compostagem é uma das formas de tratamento desse resíduo, tendo como vantagens requerer baixos investimentos e ser simples nas operações. Entretanto, para sua gestão eficiente é crucial a segregação na fonte, com ampla participação da população. Nesse sentido, compreender os motivos que levam ou não ao comportamento de separação, bem como o papel da gestão pública na condução do processo, é de suma importância na continuidade e na melhoria dos sistemas de tratamento desses resíduos. Assim, o objetivo deste trabalho foi identificar os fatores que influenciam no comportamento da segregação de resíduos orgânicos na fonte geradora, para fins de tratamento em sistemas de compostagem. A revisão sistemática foi realizada pelo método de pesquisa em arquivo. Verificou-se que os fatores influenciadores de segregação da matéria orgânica são: infraestrutura física e conveniência, educação, dados sociodemográficos, fatores econômicos, norma e influência social, feedback, hábito, comportamento pró-ambiental, confiança no sistema e fatores associados à Teoria do Comportamento Planejado. Conclui-se que não há consenso quanto à intensidade e ao aspecto (positivo ou negativo) de influência dos fatores, pois eles dependem das particularidades locais. Uma vez que existe relação de interdependência, um conjunto de fatores deve ser considerado para garantir adequado planejamento. Em sistemas de compostagem, a avaliação de eficiência da separação pode ser realizada de forma indireta, centrada na percepção do indivíduo e no autorrelato do comportamento; ou direta, com medições gravimétricas e de composição. Recomenda-se adotar ambas as formas, de modo complementar.

“…Biodegradable waste is an important topic worldwide because its potential to be used for producing energy [1][2][3] but also because, when non optimised, this stream of waste causes important impacts: when put in a landfill, even a sanitary landfill, fugitive emissions of biogas have a high impact as the contained methane is a greenhouse gas (GHG) [4][5][6]. The attention to this problem is different from Country to Country and can significantly change depending on the way of collecting waste [7][8][9].…”

One of the problems of food waste management is the acceptability of the treatment plants at local level because of the risk of odours. Anaerobic digestion as first step before composting has contributed to solve this problem, but, in the sector, it remains an opposition to large plants. That affects also food waste anaerobic digestion: people's perception is that the stream coming at the gate of the plant is not theirs. The present paper shows an alternative to the conventional approach. The aim is to reduce the scale of the intervention giving a solution also to small municipalities or to an aggregation of small municipalities. The basic idea is suitable for adaptations depending on the local availability of manure and other plants specialised on wastewater. The integrability of these plants allows reducing the costs for treating secondary streams to be managed, as discussed in the article. The extreme technological scenario is based on an anaerobic digester with unconventional pre-treatment of food waste and energy recovery, on a hydro-thermal carbonisation reactor for manure, on an ammonia separator for product recovery (by stripping), on a CO 2 separator (from off-gases), on a hydro-biochar flusher for opening to land application and on mechanised small-scale composters for small communities. The principles of the circular economy are adopted, but the economic balance is affected by the transport costs of the products. The suitability of this approach to medium income countries is discussed too.

“…Organic waste constitutes approximately 30%-50% of municipal solid waste streams in developed countries (Ponsá et al 2008;Fehr and Arantes 2015;Recyc-Québec 2015). Where conventional waste management is practiced, much of this organic waste is buried in landfills, incinerated (with the ash sent to landfill), or stabilized and used as landfill cover (Tsai 2008;Senthilkumar et al 2014;Metson and Bennett 2015a;Zabaleta and Rodic 2015).…”

The role of management instruments in the diversion of organic municipal solid waste and phosphorus recycling

Organic waste, which contains essential plant nutrients such as phosphorus, constitutes 30%–50% of municipal solid waste in developed countries. Unfortunately, much of this resource is buried in landfills or incinerated. Many jurisdictions have, therefore, adopted the diversion of organic waste and the recycling of nutrients as policy goals. We used data sets from Europe and Ontario, Canada, to explore the impact of socio-economic and management factors on the rates of organic waste diversion and examined the effect of this diversion on phosphorus recycling. Organic diversion rates were highly correlated with income in Europe and with infrastructure, such as source-separated organic waste collection, in Ontario. Significant correlations were also observed between diversion rates and the use of policy instruments such as economic incentives, legislative organic waste bans, and curbside bag limits. We estimated that 39%–63% of the phosphorus in diverted organics is returned to arable land. Ultimately, we found that although socio-economic factors influence the success of organic waste diversion, policies, accessible infrastructure, economic incentives, and legislative requirements can be leveraged to improve the recycling rate of organic waste and the nutrients they contain.
