RECOVERY OF ORGANIC WASTE THROUGH COMPOSTING PROCESS

Waste treatment involves all chemical, physical and biological processes that have the role of modifying certain characteristics of the waste in order to reduce their volume and hazardousness, thus facilitating their recovery. Among the available technologies, composting is presented as one of the most promising options for recycling the organic fraction into a valuable organic fertilizer called compost.
