“…Insufficient management, associated with a set of other factors, becomes one of the most significant problems faced by the environmental sector (Aguiar, Ribeiro, Viana, & Pontes, 2021). Since the lack of control over urban growth has been perceived, discussions and debates related to solid waste management have become increasingly common.…”

The construction industry plays a fundamental role in the economy of a developing country, representing, in most of them, approximately 3.7% to 10.5% of its Gross Domestic Product. However, it is extremely important to search for sustainable alternatives in this sector, aiming to reduce the environmental impacts generated by the production of inputs, waste generation, in addition to the inappropriate disposal of this activity in the environment. Therefore, the work aimed to evaluate the technical and economic feasibility of the incorporation of residues (Marble and Granite Cutting Waste—MW and Construction and Demolition Waste—CDW) in the production of soil cement bricks (SCB). For the development of the present work, physical and mechanical characterization of the soil, residues (CDW and MW), composites (Control, MW15%, MW25%, MW50%, MW100%, MW30%CDW70%) were performed. After manufacturing the bricks, the characterizations mentioned were carried out at 7, 28 and 60 days, in addition to the evaluation of the geometric characteristics, water absorption and strength of the bricks and microscopic analysis of the post-rupture fragments. Additionally, a cost analysis of the use of SCB was performed compared to two different construction systems (ceramic brick and concrete block). From the results of physical characterization, soil was classified as clayey-silty sand (SC-SM), while the CDW was well-graded sand and MW as sandy clay. Soil and composite plasticity characteristics ranged from weakly plastic (MW15% and MW30%CDW70%) to highly plastic (MW100%). In the compaction tests, composites with the addition of MW presented increasing values in terms of optimal moisture. The compressive strength test performed showed satisfactory results for all composites, especially for MW25%, which obtained the most significant result with 13.777 kPa at 28 days. Thus, it is concluded that the incorporation of CDW and MW for the production of SCB represents a sustainable application for civil construction.

“…Quando dispostos de maneira irregular os resíduos tendem a provocar impactos negativos aos ecossistemas terrestres e aquáticos, tornando-os um sério obstáculo para alcançar a sustentabilidade (FELISARDO;SANTOS, 2021). Associado a geração exacerbada dos mais diversos resíduos sólidos está a má gestão desses materiais é agravada ainda mais pela pandemia causada pelo vírus SARS-CoV-2 (AGUIAR et al, 2021;FELISARDO;SANTOS, 2021).…”

Com a alta demanda na produção de alimentos, a agropecuária e a agroindústria têm produzido grandes quantidades de resíduos. Os sistemas de criação da maricultura (comercial ou de bancos naturais) e avicultura comercial também são um dos responsáveis por esta alta demanda. Destarte o objetivo deste artigo foi realizar caracterização química e física de resíduos de conchas de ostras (RCOs), conchas de mexilhão (RCM) e cascas de ovos de galinha (COv). Os resíduos foram coletados em três municípios da Ilha do Maranhão que, após lavagem e secagem, foram submetidos a três ensaios analíticos: potencial hidrogeniônico (pH), verificação de carbonato de cálcio e quantificação do CaCO3 e Ca. Dentre os resíduos analisados, RCOs obtiveram valor médio superior de pH (9,5), com RCOv (9,18) e RCM (9,04) sucessivamente. RCOs apresentou maior porcentagem de cálcio e carbonato de cálcio dentre todos os resíduos investigados. Os resíduos apresentaram bandas que os caracterizam junto a aragonita e calcita. As análises realizadas indicam forte possibilidades dos resíduos serem utilizados como promotores de correção em solos naturalmente ácidos ou acidificados pelo uso de fertilizantes sintéticos, contudo mais pesquisas necessitam ser realizadas.

“…Com o advento da revolução industrial, a composição dos resíduos alterou significativamente e, com isso, foi ampliada a necessidade em pensar as estratégias que atenuassem os gargalos que seriam ocasionados pelos variados tipos de resíduos e rejeitos gerados (GOUVEIA, 2012;DEUS;BATTISTELLE;SILVA, 2015;PINHEIRO;MOCHEL, 2018;AGUIAR;.…”

The inadequate disposal of solid waste can be a practice that maximizes environmental degradation. Given the above, the present work aimed to analyze the final disposal of urban solid waste in the municipalities that are part of the Território de Identidade Costa do Descobrimento, in Bahia. The first step was the research on specialized official platforms and websites and the literature review of scientific articles. In the second stage, the Municipalities were contacted. With the exception of the Municipalities of Belmonte and Porto Seguro, the works analyzed showed a predominance of the use of open dumps. It was possible to notice a variation in the use of some terminologies. The city halls of the municipalities did not return contact, which made it impossible to access information that was not found on the platforms and in the analyzed scientific literature. It is recommended that city halls fill in the official platforms, thus avoiding the information gap, as well as studying the feasibility of creating consortiums among those who are interested in disposing of waste as recommended by the PNRS, thus preventing the impacts negative environmental influences continue to exert influences in the municipalities studied.
