“Compost is organic matter that has been decomposed and recycled as a fertilizer and soil amendment…… Modern, methodical composting is a multi-step, closely monitored process with measured inputs of water, air, and carbon- and nitrogen-rich materials. The decomposition process is aided by shredding the plant matter, adding water and ensuring proper aeration by regularly turning the mixture. Worms and fungi further break up the material. Aerobic bacteria and fungi manage the chemical process by converting the inputs into heat, carbon dioxide and ammonium.”

EnviCare® Engineering GmbH successfully uses this process as a part of the mechanical-biological waste treatment for environmental friendly processing of organic waste, such as Sewage sludge.
Used for small, simple and cost-efficient systems
Especially in smaller scale, composting is a cost-effective and in the case of simple and small systems, such as triangular windrows, also an energy-efficient method today.
