Resumo: A construção civil é um setor que utiliza uma boa parte dos recursos naturais disponíveis, como, por exemplo, os produtos de extração mineral. Em contrapartida, está atrelada aos elevados índices de impactos ambientais negativos, como pela produção desenfreada de Resíduos de Construção Civil (RCCs). Estes resíduos, quando não possuem uma destinação adequada, podem trazer consequências permanentes para o meio ambiente, sendo necessário investigar a qualidade e abrangência dos serviços de gestão e de gerenciamento de resíduos sólidos gerados nas obras civis. Logo, este estudo tem por objetivo realizar uma revisão bibliográfica da literatura quanto o impacto ambiental e o gerenciamento de resíduos sólidos gerados na construção civil. Trata-se de uma revisão integrativa da literatura, de abordagem qualitativa, com procedimento técnico de pesquisa bibliográfica sobre impacto ambiental e gerenciamento de resíduos sólidos na construção civil. Foram aplicadas na base de dados da Scientific Eletronic Library Online (SCIELO) as palavras-chave “Construção civil” AND “Impacto ambiental” OR “Reciclagem de resíduos” OR “recursos ambientais”, para identificar todos os artigos publicados no eixo temático proposto, publicados entre 2011 e 2021, em inglês ou português. Dentre os tipos de resíduos gerados pelas atividades da construção civil, os mais desperdiçados, segundo alguns autores, são gesso e argamassa. Também são referenciados materiais cerâmicos, argamassa, bem como seus componentes, compreendendo assim 90% dos resíduos que são gerados em obras. Contudo, mediante a produção excessiva destes materiais, é recorrente a identificação de que a demanda foi superior à necessidade, implicando, assim em descarte dos resíduos, gerando, ainda, prejuízo financeiro. Quanto ao gerenciamento de resíduos sólidos na construção civil, foi possível identificar que este setor é um dos que mais geram resíduos sólidos, evidenciando uma urgência de adoção de medidas que possam mitigar os impactos negativos provenientes da produção de materiais que são descartados no meio ambiente.

Body Of Knowledge

The organic fraction is usually the predominant fraction in municipal solid waste, so its recycling is a potential alternative to disposal in landfill sites, as well as helping to reach targets included in the European Circular Economy Package. The existing body of knowledge in this research field is very large, so a comprehensive review of the existing scientific literature has been considered of interest to provide researchers and professionals with a detailed understanding of the status quo and predict the dynamic directions of this field. A systematic literature review and bibliometric analysis have been performed to provide objective criteria for evaluating the work carried out by researchers and a macroscopic overview of the existing body of knowledge in this field. The analysis of 452 scientific articles published from 1980 to 2019 has shown that the application of composting technologies is relevant, especially since 2014, when policies aimed at reducing emissions to the atmosphere were increased and focused on the use of this waste fraction to produce biogas. Nevertheless, the scientific field is still evolving to impose a model of a circular economy; in fact, emerging studies are being conducted on the production of biomethane, contributing to the decarbonised energy system.

The Commonwealth of Virginia has mandated a recycling goal of 10% of municipal solid waste (MSW) by 1991, 15% by 1993, and 25% by 1995. Yardwaste (leaves, grass clippings, shrub and tree prunings) comprises 15% to 20% of MSW going to landfills daily. Yardwaste can be recycled by collecting material, piling it into large windrows, and allowing it to decompose by comporting. The finished product can be used as a soil amendment by nurseries, landscapers, farmers, local/state government projects, and homeowners.The Virginia Co-op. Ext. Service at VPI&SU was authorized to perform a feasibility study on implementing a statewide yardwaste comporting program. The methods included a literature review, site visits in other states to assess technologies, and surveys to determine potential uses and users of composted yardwaste in Virginia.The study was presented to the Virginia Dept. of Waste Mgmt. in November 1989, and as House Document No. 34 to the Virginia General Assembly. Three bills and one joint resolution are pending.

The waste management strategy is expected to minimize the negative impact on the environment. In the capital city of Dili, the waste management strategy can be categorized as very concerned. Based on the data from the Ministry of State Administration shows that in 2020, people in the capital of Dili produce waste 250 tons per day. The reality of solid waste in the capital city of Dili shows a severe problem in the waste management process and strategy. This study aims to examine problems in waste management strategies and their impact in the capital city of Dili. Through a literature review approach, a scientific study will be carried out on several scientific articles related to the waste management system and the reality of solid waste in capital city of Dili. The results show that people in the capital of Dili, still use the classical system in managing solid waste. Weak government system and local regulations regarding to solid waste management, and the lack of the waste management industry based on R3 (reduce, reuse, recycle) are the main factors for the community still using the classical system. This reality harms the environment and people in the capital of Dili.

This paper takes on the current R&D on the use of biomass from coffee for electric power. This comprehensive literature review aims to synthesize, organize and structure on topics related to the use of solid waste, such as coffee pulp and husk for boilers for power plants. Initial available literature shows new technologies being implemented to transform and improve processes to obtain and generate this type of renewable energy. Using a systematic review, such coffee solid waste is presented as a bioenergy alternative to the sustainability of coffee processing plants. The results show the strengths and weaknesses of its use for energy, which may have significant impact on coffee producing countries, as it is one of the most booming industries of the countries from the equatorial tropics. Despite a wide range of applications of such coffee waste, we have identified few studies on the application of pyrolysis from such biomass power generation. This first review of literature on the subject has both practical implications about the current trend of coffee biomass as a means for generating energy, as well as it can be a basis for the scope for future research on the implementation and sustainability in coffee producing regions.

In the light of one of the most common waste management issues in urban areas, namely the elimination of municipal solid waste (MSW; about 486 kg of the waste per capita were generated in the EU in 2017), this study discusses one technique as an outlet in the construction industry for the by-product of the waste’s incineration in energy recovery facilities (i.e., MSW incinerator bottom ash—MIBA). There have been some investigations on the use of MIBA as partial replacement of cement to be used in cementitious composites, such as concrete and mortars. However, the waste’s incorporation ratio is limited since further products of hydration may not be produced after a given replacement level and can lead to an unsustainable decline in performance. In order to maximize the incorporation of MIBA, some research studies have been conducted on the alkali activation of the waste as precursor. Thus, this study presents an extensive literature review of the most relevant investigations on the matter to understand the material’s applicability in construction. It analyses the performance of the alkali-activated MIBA as paste, mortar, and concrete from different perspectives. This literature review was made using search engines of several databases. In each database, the same search options were repeated using combinations of various representative keywords. Furthermore, several boundaries were made to find the most relevant studies for further inspection. The main findings of this review have shown that the chemical composition and reactivity of MIBA vary considerably, which may compromise performance comparison, standardization and commercialization. There are several factors that affect the performance of the material that need to be considered, e.g., type and content of precursor, alkaline activator, curing temperature and time, liquid to solid ratio, among others. MIBA-based alkali-activated materials (AAM) can be produced with a very wide range of compressive strength (0.3–160 MPa). The main factor affecting the performance of this precursor is the existence of metallic aluminum (Al), which leads to damaging expansive reactions and an increase in porosity due to hydrogen gas generation stemming from the reaction with the alkaline activator. Several approaches have been proposed to eliminate this issue. The most effective solution was found to be the removal of Al by means of eddy current electromagnetic separation.
