COMPOST: PRODUCTION, USE AND IMPACT ON CARBON AND NITROGEN CYCLES

摘要

The importance of composting in countries of the European Union has been enhanced by recent European legislation, which has forced a switch from the landfill of organic wastes to their recycling and transformation. This should promote the concept that composting is a way of obtaining useful and valuable products from waste materials, rather than just a method to dispose of them. Different official institutions from several countries have set limits of certain non-desirable components in compost, as well as the quality parameters to define compost use, but an international standardisation is required.
