Composting of EFB and POME Using a Step-feeding Strategy in a Rotary Drum Reactor: The Effect of Active Aeration and Mixing Ratio on Composting Performance

New Ecological Composter Powered by Solar Panels without Battery to Produce Organic Fertilizers

“…Space consumption, leachate production, groundwater pollution, as well as greenhouse gas emissions are major problems that push the state to pay additional costs each year 2884.5MDH (about 297 Million Dollar) [6] [7].…”

“…Composting is an aerobic biological process that transforms organic matter into a homogeneous product called compost via micro-organisms, bacteria and fungi that live in specific conditions of temperature, oxygen and humidity, keeping an optimal temperature between 55C° and 65° as well as humidity between 40% and 65%, carbon/nitrogen ratio and particle size [10] [11] [12]. There are several composting technologies known internationally, including open, closed or reactor-based composting, the latter gives vermicompost-type fertilizer which is characterized by the elimination of odors and accelerates the treatment process as well as it provides a favorable environment for the growth biodegradation of organic material [13] [14].…”
