Tunnel composting technique

GICOM is one of the first companies in the world which applied the tunnel composting techniques for composting Garden Fruit and Vegetables waste. Besides composting Garden Fruit and Vegetables waste the concept is also applied worldwide for composting the following types of waste: sludge, commercial waste, animal waste, digested residu, manure, municipal waste, green waste and other organic waste products.

GICOM tunnels are build in a modular system where different tunnel sizes are used. The sizes can vary from 15 till 50 meters in length and from 4 till 8,5 meters width. These results of filling capacities between 60 and 600 tonnes per tunnel. Each facility holds a different number of tunnels. In practice this varies between 3 until more than 50 tunnels per facility. As a result tunnelfacilities can handle between 4.000 and 400.000 tonnes of material per year.
GICOM facilities that have reasonable clean input waste streams, produce compost that can be used as a soil improver for agriculture, horticultural or soil improvement. This way of recycling creates a circle for organic based material which is extremely important for a good structure of the ground. It keeps minerals and organic fractions where they belong.
GICOM tunnels are renown for high aeration fold. The oxygen, temperature, moisture and ammonia are distributed very well, as a result of this. Therefore the organic fraction is composted extremely efficient in GICOM tunnels. Depending on the input material and the requested compost output the composting process in tunnels takes between 2 and 4 weeks. After this period the material finishes the composting process on a GICOM aerated floor. Gicom delivers tunnels that can be filled using a front end loader or an automatic filling system. Also for emptying tunnels GICOM supplies automatic systems. The GICOM tunnel system can be defined as a system with a low demand on labour per ton of waste input material.
