====== Drum Composter ======

//Drum composter: drum-shaped compost container with good mixing of the
biomass for rapid composting of biowaste//

**Bio-waste becomes valuable fertilizer**

During composting, organic materials such as fruit and vegetable residues, egg shells and
coffee grounds or garden waste are decomposed and converted into nutrient-rich humus,
which can then be used as fertiliser in raised beds. There are many different types of
compost containers. The material and the size of the compost container is important.

They are made of wood, metal or plastic. It is important that the compost is always well
aerated so that the organisms (bacteria, fungi, worms, insects, etc.) that are responsible for
the composting process are always supplied with air and water. In the drum composter the
mixing is very easy, it was built by students of the university in Kleve within the scope of a
student project.
