The worldwide production of waste tires (so called "end of life tires" - ELT) grows every year. The same situation is in the Czech Republic and in the countries of the European Union, but also in the world. Every year about 3.4 million tonnes of used tyres (part worn + end of life tyres) are generated in Europe, of which 3 million tonnes are either recycled or recovered. This amounts to approximately 300 million units. The composition and energy characteristics of tires are a signif-icant source of material, energy and also raw material. Calorific value tires ranges from approximately 25 to approximately 32 MJ • kg-1. The calorific value is comparable with conventional fossil fuels, which is due to the high proportion of hydrocarbons (over 75%). For these reasons, an alternative tire conventional fuels. The aim of the research is focused on the second part of product life cycle - the tire at the end of lifetime. The main possibilities of utilization of used up tires after end of their life are as follows: retreading, recycling (production of granulate), energy and material utilization in a cement factory, pyrolysis (production of pyrolytic products) and formerly used waste storing. Another objective of ...
The development of recycling - reusing resources used to build vehicles, machines and equipment is presently forced by increasingly rigorous environment protection requirements. Recycling is becoming a new branch of economy protecting the natural environment, but it can also bring considerable economical profits, develop the technical infrastructure of boroughs and counties and also create new work places.The development of recycling leads to the emergence of a number of complex problem of technical, economical, social and legal nature forcing resourcefulness and creativity in decision making. These problems are of great importance in the scope of vehicle and household hardware due to the fact they are the most produced and used by the people. The article presents the problems of vehicle, machines and equipment recycling in Poland concentrating especially on the problem of plastic recycling. Aforementioned problem is especially important in Poland due to the fact of the existence of large quantities of scrapped plastic, it's long natural neutralization process and the lack of citizen awareness (creating illegal dumps in forest and rivers, emitting dangerous and toxic substances by burning plastic in household fires etc.). ...
