During the biomass densification can be recognized various technological variables and also material parameters which significantly influences the final solid biofuels quality. The paper deals with the experimental research of the relationship between technological variables and material parameters during densification of acacia wood sawdust. The main goal of presented experimental research is to determine the relationship between compression pressure, pressing temperature and raw material moisture content and par...

This contribution describes developments in the area of plastic recycling aimed at the reuse of waste materials for the manufacture of a useful product. Throughout development of the concept пїЅmodular flood barrier structureпїЅ, the recovery of plastic materials was assessed, primarily, plastic waste from automobiles and industry. The investigators filed a utility model application, no. SK 5847 Y12, entitled пїЅModular flood barrier structureпїЅ. Terms of the type and composition of source material, polypropylene...

Processing the waste paper produces huge amounts of waste - papermaking sludge. This kind of waste includes around 50 % of inorganic material and high proportion of water. Its current economic recovery is very limited, which affects the overall efficiency of recycling paper. However, the elementary and chemical composition has a high potential for wider and more economically efficient use in various industrial fields. The object of this paper is research of composition and physical properties of such sludge from o...
