New Publication - Greenhouse gas emissions from organic waste composting. A review.

Greenhouse gases (GHG) such as carbon dioxide, methane and nitrous oxide from compost are of special relevance for global warming. Composting is inherently a process generating gaseous emissions.

This article reviews the emission of GHG from composting gases, from detection and measurement to minimisation and abatement. Special emphasis is given to the measurement of GHG to obtain reliable emission factors for the different composting technologies. These factors will help to compare different waste treatment options based on overall analysis tools such as life cycle assessment.

This work has been performed in collaboration of several research groups and institutions such as GENOCOV, GICOM from UAB, CRA-RPS from CRA and CSIC. GENOCOV has mostly participated in the abatement possibilities of such GHG.
