Rural areas are often neglected with respect to solid waste management, and if some kind of management is in place it inadequate, causing harm the rural population environment, especially when open burning dumping practiced. These practices performed areas/isolated communities worldwide. In today's scenario, any actions taken by cities generally do not focus on implementing a circular economy, that is, closing loops resource recovery, which important increase quality life populations. this...

Implementation of resource recovery technologies is becoming increasingly important, as humans are exhausting the world's natural resources. Recovering nutrients and water from wastewater treatment systems will play an important role in changing current trends towards a circular economy. However, guidance still needed to determine most appropriate way do this. In this study two decision-support tools, sanitation planning software (Santiago) life cycle assessment (LCA), were applied identify...

Life cycle assessment (LCA) is a commonly used method for assessing environmental impacts of systems, but cannot produce absolute values, i.e. comparison with existing calculated which represents limits what can be emitted into the environment. Therefore, sustainability assessments have been developed to assess against planetary boundaries (PBs) safe operating space humanity. Since PB-LCAs are novel, it useful analyze both results from this and conventional LCAs, something has not done...

Biosolids are generated at Wastewater Treatment Plants (WWTPs) and they enable closing the loop of valuable resources that beneficial to soil-plant system, however, legal aspects viability principles circular economy must be considered. Studies evaluate chemical properties tropical soils subjected long-term applications biosolids scarce, especially with regards Emerging Organic Micropollutants (EOPs), which makes present work original. Thus, study aimed statistically through Tukey test...

RESUMO Diante da tendência mundial de crescimento população e consequente geração resíduos sólidos urbanos, surge a necessidade utilização ferramentas para avaliação sustentabilidade dos sistemas gerenciamento, visando à tomada decisão mais consciente. A chegada do conceito economia circular, assim como promulgação Política Nacional Resíduos Sólidos, consistiu em substancial quebra paradigmas que despertou discussões maior preocupação com o ciclo vida produtos redução resíduos. Sendo assim,...

Adequate treatment of organic manures and digestates from livestock production should reduce environmental impacts provide well-defined attractive biofertlisers for a crop market, which can promote the closure nutrient cycle in agriculture. In this sense, survey was conducted during autumn 2021 to investigate Swedish farmers' perspectives on fertilisers use. The consisted an online questionnaire, distributed broadly social media, homepages, different types networks at course events order...

Seeking to use wastes disposed in the environment by incorporating them into low environmental impact materials, study aimed analyze effect of using sugarcane bagasse ash and leather dust generated tanneries soil–cement brick mixtures. The experiment involved characterization used soil mixtures various ratios, molding, analysis performance parameters after an assessment material microstructure heavy metal leaching (chromium). comprehensive strength against compression decreased with...

Quilombolas are descendants from black slaves who founded isolated communities, the Quilombos. Many of these communities have considerable needs, especially because most located in rural areas, including waste management, which affects their health and requires studies area. Based on this, this paper shows current conditions management two quilombola urban rural, through site visits, questionnaires gravimetric analyses. Therefore, it was possible to notice that community has better than...

Diferentes alternativas para o reúso de esgoto doméstico tratado têm sido estudadas forma extensiva, buscando principalmente tecnologias tratamento com melhor desempenho na remoção patógenos. As soluções baseadas natureza se destacado pela sua capacidade poluentes, processos ecológicos, simples e robustos, entretanto, necessitam maiores estudos relacionados aos riscos que envolvem água a partir do tratado. Sendo assim, objetivo deste estudo foi quantificar os à saúde humana no fins...

No atual cenário de limitação recursos naturais, o desenvolvimento sistemas integrados e sustentáveis tratamento esgoto implica em uma mudança estrutural da visão acerca função estação esgoto: simples condicionadora para a disposição final mais segura recuperação aproveitamento dos subprodutos do esgoto. Para acompanhar essa mudança, é preciso garantir segurança desde geração até aplicação gerados. O objetivo desta nota técnica introduzir manual Plano Segurança Saneamento Organização Mundial...

Como escolher a alternativa de esgotamento sanitário mais sustentável? Técnicos e tomadores decisão da área saneamento normalmente encontram dificuldades na escolha dos critérios serem avaliados para sistemas sanitário. Para guiar este processo, esta Nota Técnica, com base em pesquisa bibliográfica, apresenta cinco dimensões sustentabilidade (ambiental, econômica, social, técnica institucional) os indicadores/critérios utilizados cada dimensão. Também são elencadas as principais ferramentas...
