Environmental Aspects Of Home Composting Of Organic Household Waste

Research output: Chapter in Book/Report/Conference proceedingArticle in proceedingsResearchpeer-review

Abstract

Six composting units were monitored during a two-year long experimental campaign. Data regarding chemical compositions of waste inputs and outputs, gaseous emissions and leachate productions were collected, organized in mass balances and assessed by means of LCA. The management of the home composting unit was very relevant for the environmental performance of home composting, as the turning frequency influence the emissions of CH4 which is the main responsible for potential impacts on global warming. Results showed that overall home composting has low environmental impacts (between -2 and 16 mPE Mg-1ww for the non-toxic categories and between -0.9 and 28 mPE Mg-1ww for the toxic categories) and has similar or even better environmental profile that incineration and landfilling in some of the impact categories.
