Introduction: Countries around the world are looking for an appropriate, stable, and affordable replacement for the natural energies. Therefore, the waste is considered as an available resource to produce energy, which by controlling, its effects on the environment could be minimized. Materials and Methods: To conduct this review article, the scientific data related to the topic were gathered ...
Application of the Triangular Model in quantifying landfill gas emission from municipal solid wastes
Municipal solid waste landfills are significant parts of anthropogenic greenhouse gas emissions. The emission of significant amount of landfill gas has generated considerable interest in quantifying such emissions. The chemical composition of the organic constituents and potential amount of landfill gas that can be derived from the waste were determined. The chemical formulae for the rapidly bi...
A preliminary study of the manufacture of dyes and pigments was conducted to determine if process waste streams might contain hazardous material. The study first identifies the dyes and pigments that belong to the major segments of the industry, the amounts produced, and the known U.S. producers. The chemistry of these dyes and pigments is discussed as well as the overall production process and...
This paper presents a forecasting study of municipal solid waste generation (MSWG) rate and potential of its recyclable components in Kuala Lumpur, the capital city of Malaysia. The generation rates and composition of solid wastes of various classes such as street cleansing, landscape & garden, industrial & constructional, institutional, residential and commercial are analyzed. The past and pre...
Beach waste and litter composition and evolution on popular urban (located in the main nucleus of the municipality) and urbanized (located in residential areas outside the main nucleus) beaches of the Costa Brava (Catalan coast) were assessed during the bathing season. Waste and litter production (amount and composition) were affected by urbanization and varied during the summer. Urban beaches ...
Anaerobic digestion (AD) is a widespread microbial technology used to treat organic waste and recover energy in the form of methane ("biogas"). While most AD systems have been designed to treat a single input, mixtures of digester sludge and solid organic waste are emerging as a means to improve efficiency and methane yield. We examined laboratory anaerobic cultures of AD sludge from two source...
13 Abstract Reactive waste dumps with sulfide minerals pro14 mote acid mine drainage (AMD), which results in water and 15 soil contamination by metals and metalloids. In these systems, 16 contamination is regulated by many factors, such as mineral17 ogical composition of soil and the presence of sorption sites 18 on specific mineral phases. So, the present study dedicates 19 itself to understan...
