Abstract from: UAB Divulga

 

Anaerobic digestion (AD) technology is used commercially around the world, especially in Europe, which has set some challenging targets to diversify its energy mix with more renewable energy. AD is not a new technology. It was already known in the 17th century, but it was only in the 1980s that it started to be used more widely for treating industrial and municipal wastewater, sewage sludge or municipal solid waste. As it is now a mature technology, it could be key to reducing organic waste, recovering the energy contained in biomass, and generating biofuels and energy.

“Science for Environmental Policy” echoes an article from our Research Group

In its issue 411, the free weekly News Alert from the European Commission, Science for Environmental Policy highlighted our paper published in Resources, Conservation and Recycling

Colón, J., Cadena, E., Belen Colazo, A.B., Quiros, R., Sanchez, A., Font, X. & Artola, A. (2015). Toward the implementation of new regional biowaste management plans: Environmental assessment of different waste management scenarios in Catalonia. Resources, Conservation and Recycling. 95: 143–155. DOI:10.1016/j.resconrec.2 014.12.012.

Science for Environmental Policy emphasized:

“Researchers have designed and proposed a new organic waste management plan for Catalonia, Spain, and presented it in a recent study. They say that the plan would reduce a number of environmental impacts that arise from landfilling biodegradable waste, including natural resource depletion, acidification, and eutrophication.”

Parameters affecting the composting process

In order to control and optimize the biokinetics of the composting process to produce a compost of desired quality, it is important to understand the factors that inÀuence the process. A composting matrix is an ecosystem of interdependent interactions between biotic and abiotic factors that cause degradation of organic matter. The abiotic and biotic factors playing key role in the composting process (Pietronave et al. 2004; Gajalakshmi and Abbasi 2008) are described next.

The composting process: an overview

Although there is no universally accepted definition of composting, Haug (1993) uses a practical definition of the process, which provides all the main points to obtain a successful process: “Composting is the biological decomposition and stabilization of organic substrates, under conditions that allow development of thermophilic temperatures as a result of biologically produced heat, to produce a final product that is stable, free of pathogens and plant seeds, and can be beneficially applied to land.”
