AbstractIn this study a new generation of plate-type laboratory air treatment biofilter is applied for the removal of gaseous contaminantsfrom air. The packing material for the biofilter consists of porous plates arranged vertically one after the other to produce acapillary humidification effect. The porous plate is made of polymer to secure the stiffness of the plate. Birch fibre granulesthermally treated in a steam explosion reactor are fixed on both sides of the polymer board. The granules ar...

AbstractEnd-of-life tires are waste materials that pollute landscapes when they are disposed of in tire dumps. However, its life cycle is notfinished when they are scrapped. The rubber of end-of-life tires could be used for new purposes as construction material in roadrehabilitation. A gap-graded mix characterization was carried out in this work by means of laboratory and field performancetests. The mixture has a high content of crumb rubber (CR) by weight of bitumen. Crumb Rubber was added to t...

Abstract Extensive use of plastics leads to the increase of non biodegradable wastes that have to be recycled due to both dramatically decrease of natural resources to producing them and to their increasing need as well as due to environmental issues. Most of goods made by materials based on wastes have to be commonly used by people. Antibacterial character of those is necessary to avoid epidemics. This paper deals with determination of antimicrobial character of materials based on polymeric...
