BIOSTOP PROCESS

Ziel

The project aims to demonstrate a method for drying and storing municipal wastes during the summer months for eventual combustion in winter when demand for thermal heat is at its peak.
The process BIOSTOP could not been proven conclusively since problems of MSW auto-ignition hindered the operation of the plant. Auto-ignition of MSW can result in fire and possibly explosion. However, the advantages of storing MSW during the summer months to be incinerated during the winter when heat demand is high were demonstrated.
A municipal waste incineration plant will be constructed providing heat to a district heating network. Waste entering the plant is shredded and automatically conveyed into two separate waste storage units, one feeding a factory incinerator; the other for long-term storage. During the summer, waste is incinerated, and electricity is generated for use in the plant. The hot incineration air is fed over the waste contained in the other (Biostop) waste storage unit, reducing its moisture content and thereby preventing fermentation processes and the generation of polluting effluents and odours.
In winter when demand for thermal and electrical energy is highest the dry waste within the 'Biostop' unit is combusted. The thermal energy provided by the 'Biostop' waste is used for a district heating network resulting in a natural gas saving of 3.5 GWh/y and a domestic fuel saving of 3.3 GWh/y. The project is innovatory because it allows wastes to be stored for long periods without the generation of obnoxious effluents and odours. It also allows energy production from waste combustion to be matched with the seasonal fluctuations in demand for energy.
