Production of biomass-plastic composites is one of the interesting recovery possibilities for waste biomass and HDPE material. The big issue in this research area is to produce the composites with acceptable and competitive level of quality which is determined through the final mechanical properties of composites. Meaning of this paper is to present the research finding for determination of the mechanical properties of waste raw materials based biomass-plastic composites. Raw material variables influence, especial...

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...
