In the 1990s, waste problems became social and secondary pollution occurred during incineration and landfill treatment, which led to an increasing interest in food waste and sludge, which are the most problematic of the waste properties. Most of them are classified as organic wastes because they contain many organic substances that can be decomposed by microorganisms. The problem factor in the treatment of these organic wastes is high moisture content, which shows food waste around 80-85% and sludge 75-80%. This high water content lowers the calorific value at the time of incineration, increasing the amount of auxiliary fuel used, and in some cases incomplete combustion. In addition, it is an increase factor of leachate in the landfill stage, and organic matter is rapidly decomposed at high moisture content, which may cause odor. Due to these problems, the landfill control movement occurred in the 90's, and induces imports while suppressing moisture as much as possible, but still causes many problems.

After the problem of organic waste such as food waste occurs and research into resource recycling of the organic waste is progressing, the recyclable material in the waste management and treatment system is classified by separate collection and mechanical screening. Remaining organic matter is how to re-resource these organic matters has emerged as an important key, and the ultimate alternative to the recycling method is the composting by aerobic microorganisms.
