A COMPOSTING METHOD, COMPOSTING APPARATUS AND METHOD AND APPARATUS FOR DELIVERING MICROWAVE ENERGY TO LAYERED MATERIAL

摘要

A composting method in which decomposable material, such as industrial waste, night soil and kitchen waste, is converted in a bed to mull in a mold-producing process with the aid of microorganisms. The method is mainly characterized in that the bed of decomposable material is heated, when necessary, by means of microwave energy in order to adjust the working temperature of the bed as a stage in controlling the mold-producing process so as to obtain a desired mold-producing rate and/or a desired final product. The invention also relates to a composting plant and to a method and an arrangement for delivering microwave energy to layered composting material.
