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 old paper recycling. The work analyzes the possibilities of the sludge material recovery and aims to develop a new product for the construction industry - building plates with different physical properties and their areas of application. Realized experimental research has shown high potential of material recovery of this waste. Research results show that the new product developed on the basis of the papermaking sludge achieves excellent mechanical properties. Thanks to this way, the material recovery of sludge from old paper recycling obtains not only economically efficient new product but also environmental benefits.
