CZ109-TH-Compost_biochar/COMP

The biochar addition effect to change the properties of compost

Description

Composting process (intensification of organic matter decomposition) by addition of biochar.

Sector

A1.6Support activities to agriculture and post-harvest crop activities

Needs/ Problem statement

Increasing the composting rate, especially when processing bulky materials (urban green waste, sludge), which are increasingly produced by society.

Objective

Increasing the composting rate and improving the physico-chemical and chemical properties of the final composts and the composting process by the addition of biochar. This is mainly to increase nutrient and moisture retention, immobilise heavy toxic metals and reduce nitrogen losses.
