Abstract

In this paper the study of recycling technology for production of refuse derived fuel (RDF) is described. Various types of wastes (wood, carton, paper, plastic and textile) were pro­cessed by two-shaft and single-shaft shredders to obtain the output product (1–2 mm), which is suitable for briquetting process. For samples manufacturing the briquetting equipment developed at Slovak University of Technology in Bratislava was used. Technological test showed that by briquet­ting of the municipal waste higher pressing temperature and compacting pressure should be applied. For quality evaluation of the manufactured briquettes the density and strength properties were determined. The mechanical strength of briquettes from RDF increased after mixing it with wood and paper wastes. The influence of different parameters (fraction size, moisture content, compacting pressure and temperature) to briquette quality was studied. To determine the calorific value of the briquetting stock the tests in the chemical laboratory of the Department of Thermal Engineering of TUT were performed.

Keywords

recycling, municipal wastes, refuse derived fuels, briquetting technology.
