Anaerobic digestion is a biotechnology that can be used to convert various biodegradable organic materials into methane-rich biogas fuel. The anaerobic digestion of municipal solid waste and sewage sludge is a process that has become a promising technology in waste management throughout the world .Digestion occurs in a four-step process: hydrolysis, acidogenesis, acetogenesis and methanogenesis...

Methods to treat kinetic data for the biodegradation of different plastic materials are comparatively discussed. Different samples commercial formulates were tested aerobic in compost, following standard ISO14855. Starting from raw data, conversion vs. time entries elaborated using relatively simple models, such as integrated equations zero, first and second order, through Wilkinson model, or a...

This study investigated effects of mature compost on gaseous emissions during composting using pig manure amended with corn stalks. Apart from a control treatment, three treatments were conducted with the addition of 5% (wet weight of raw materials) of mature compost: (a) mixing raw materials with mature compost at the beginning of composting; (b) covering raw materials with mature compost thro...
