Recycling of waste tires in the light of binding law in Poland
PublikacjaA risings of large quantities of used rubber products, especially used tires has been increasing every year in Poland, in 2006 it was 160 thousand. The waste management and recycling of used tires become a major environmental problem. Well known methods of utilization of used tires are presented in this article. The main problem is ignorance of the law by tyre manufactures and users. In Poland first act on waste introduces ban...

Microwave treatment in waste rubber recycling – recent advances and limitations
PublikacjaEnvironmentally-friendly microwave heating is increasingly used in polymer chemistry and technology. The selectivity and highly efficiency in the heat transfer present a huge advantage in systems based on recycling, improving their productivity and economic competitiveness. In case of the industrial recycling of waste rubbers, especially end-of-life tires, microwave-induced devulcanization and pyrolysis are nowadays considered...

Pilot- scale plant for material recycling of whole waste tires
PublikacjaContinously growing demad for all kinds of vehicles and general tendency to regular exchange of tires are causing growth of scrap tires which need management. A risings of large quantities of used rubber products, especially used tires has been increasing every year in Poland, in 2006 it was 160 thousand. The waste management and recycling of used tires become a major environmental problem. It is worth noticing that tires which...

Pyrolysis Process of Whole Waste Tires as a Biomass Energy Recycling
PublikacjaThe article is devoted to the description of material recycling of whole waste tires, including a new method of pyrolysis process, resulting in the final products: technically oil fractions (rubber plasticizer of rubber compounds) or diesel fuels (light, medium and heavy), activated carbon, gas fuel and steel scrap. Operational and performance tests of the first version of the pilot plant, consisting of three contributions cooperating...

CURRENT TRENDS IN RECYCLING OF PHOTOVOLTAIC SOLAR CELLS AND MODULES WASTE
PublikacjaIn comparison to other energy producing techniques, photovoltaics (PV) is one of the most promising options: no emission of any matter into the environment during operation; extremely long operation period (estimated average: 25 years), minimum maintenance, robust technique, aesthetic aspects. The use of photovoltaics is rapidly increasing, and the respective market is developing accordingly. Although PV manufacturing equipment...

Thermoplastic polyurethanes with glycolysate intermediates from polyurethane waste recycling
PublikacjaThe polyol is a major component in polyurethane formulations and therefore introducing to the formulation recycled polyol (obtained during decomposition process) allows decreasing the usage of pure petrochemical components. In this work, thermoplastic polyurethanes were prepared using various mixtures of a petrochemical macrodiol poly(ethylene-butylene adipate)diol (PEBA) and a recycled glycolysate intermediate, called glycolysate...

Recycling of Waste Rubber by Thermo-Mechanical Treatment in a Twin-Screw Extruder
PublikacjaRecycling of waste tires is a significant issue considering both environmental and economic aspects. One of the leading recycling routes is the shredding of tires resulting in the generation of ground tire rubber. This material can be easily introduced into various polymer matrices as a filler, reducing the use of conventionally applied petroleum-based materials. In such cases, it is essential to ensure sufficient interfacial compatibility,...

Structural Assessment of Reinforced Concrete Beams Incorporating Waste Plastic Straws
PublikacjaThe behavior of reinforced concrete beams containing fibers made of waste plastic straws (WPSs) under the three point bending test is examined. The effect of WPS fiber addition on the compressive and split tensile strength is reported. Four concrete mixes were prepared. The control mix PS-0 had a proportion of 1 cement: 1 sand: 2 coarse aggregate and a water cement ratio of 0.4. In the other three mixes PS-0.5, PS-1.5 and PS-3,...
