Increase in energy efficiency of tunnel composting by bio leaching and biogas production

Abstract

Bio waste treatment can be done by composting or by digestion. Both ways of treatment have their advantages and disadvantages. The increase in energy efficiency of tunnel composting approached by a bio leaching system and bio gas production is one part of the EnBV research project. The reduction of organic matter by bio leaching and the enrichment of carbons in the leachate water can be used for increasing the energy efficiency.
