The Biomal Concept

 

The conventional way of handling animal by-products is to crush, sterilise, dry and pulverise it after separation of the animal fat. The separated fat can be combusted in regular oil burners and are today used in for example heat and power plants as a substitute for oil. The meat and bone meal (MBM) is widely used in Europe for energy generation, cement manufacture and the produced ash for road building. Processing the raw material into fat and MBM is very energy consuming and unnecessary complicated and expensive since the animal waste any how have to be incinerated.

 

An easier, cheaper, more energy effective and environmentally favourable concept was hence developed by the companies Konvex and S.E.P. Scandinavian Energy Project. The concept is called the Biomal™ concept. Compared to the conventional rendering process the Biomal™ concept has several advantages which will move the state-of-the art forward.

 

The Biomal concept is less complicated while the energy demanding processing of the raw material into fat and MBM is removed. The raw material is just crushed and grinded and then pumped to a fluidised bed boiler where it is co-combusted together with a base fuel such as wood chips, peat or municipal wate. Energy is recovered from the animal by-products by producing renewable heat and electricity and the net outcome of energy is considerably increased.
