Energy use of biodegradable municipal waste at cement plants
Original language description
In the Czech Republic, the obligation of municipalities to ensure their residents separated collection of biodegradable municipal waste (BDW) was enacted, nevertheless the issue of further management of thus collected waste has not been satisfactorily solved so far. Material recovery of bio-waste is difficult as capacity of biogas stations and composting plants is not relevantly adequate for processing such a huge amount of material. Also the disposal of final products (compost substrate, etc.) is relatively low and their sales do not cover operating costs. Due to this and other reasons (strict legislative requirements regarding management of kitchen waste and application of composts and purified biological sludge to arable land), most bio-waste is still being deposited at landfills. Since BDW has certain energy potential, it is more than desirable to seek possibilities for its thermal processing. The physical and chemical qualities of the material imply that it contains a considerable amount of moisture which could be a limiting factor. On the other hand, results of laboratory analyses proved that it contains only a limited number of toxic substances. During clinker manufacture at cement kilns, it is necessary to reach extremely high temperatures which requires incineration of huge amounts of suitable and high-calorific fuels which, in addition, have to contain certain necessary elements (carbon, iron). Adversely, chlorine content is completely undesirable. Thus cement plants seek ways how expensive fuels could be replaced by various types of alternative fuels.
