Açaí seed ash (ASA) is a waste product from processing the açaí fruit and burning seeds for cogeneration purposes. The present study evaluated use of ASA Brazilian Amazon as partial Portland cement replacement in self-leveling mortars (SLM) social-interest buildings. fresh hardened state properties were accessed with 5% 10% content, life cycle assessment was performed to evaluate greenhouse gas (GHG) emissions. maximum transport distance enable building material determined by sensitivity...
Mining is an activity that generates inputs to different production chains, making it essential for any country’s development. However, causes environmental, economic, and social impacts must be considered. The Law provides guidelines, through laws regulations, so the can carried out in environmentally, economically, socially sustainable way. In this paper, analysis was conducted of application some peculiar characteristics Brazilian (locational rigidity, priority granting, among others)...
This study analyzed the crushed stone mining sector and its recent evolution. The research was conducted through a bibliometric analysis in CAPES Portal from 2007 to 2017. period with highest concentration of publications 2013 2016, countries most substantial number are USA China. advancement technology shows how improvement equipment reflects efficiency production. Through an overview market, it observed that European production presented stability last five years, while American increased...
The management of the açai palm, a species Euterpe genus, has grown in recent years mainly for extraction palm heart and pulp fruit called açai. After the' pulp, there is significant generation residues, as discarded seeds account approximately 85% fruit. Therefore, this research aims to characterize seed after processing, well evaluate potential thermally processed use soil-cement bricks. morpho-anatomy tests were performed, including moisture content, loss ignition, ash thermogravimetry,...
Companies that manufacture poles generate several negative environmental impacts, whose extent needs to be assessed find ways mitigate them. In this research, Life Cycle Assessment (LCA) was used as a methodology measure the potential impacts throughout poles' life cycle. Primary data (amount of cement, gravel, sand, steel rebars, energy, water) were collected from industries located in Teresina, Piauí, Brazil, and information Ecoinvent 3.7.1 database (transport, solid waste, liquid...
Abstract The upholstery remanufacturing service is an activity that provides for the sale of products contain reused items, extending their lifespan. objective this study to propose a simple and feasible Environmental Management System (EMS) small businesses, particularly, company sector. implementation existing EMS standards hampered by lack elements in companies. Thus, still far from reality these enterprises. Visits were made twenty-eight companies Teresina, Piauí, Brazil, get know sector...
A crescente demanda por produtos industrializados acarreta aumento na extração de recursos naturais, especialmente, minerais. atividade minerária gera impactos ambientais, cujos efeitos podem se prolongar muitos anos. Os resíduos e rejeitos descartados são importantes fontes impacto da mineração. Fatores ordem econômica, social ambiental apontam para a insustentabilidade desse modelo linear economia. Entre as soluções apresentadas, estão o economia circular logística reversa. O objetivo...
