Description
In general 50-60 thousand tons of waste-tire accumulates annually in Hungary. Industrial and communal waste-rubber is discarded in even larger quantities. Due to their low efficiency and polluting effects, methods applied for handling rubber-waste cannot be considered long-term solutions. Pirolisis, a process based on thermal decomposition, is one of the methods for the treatment of waste-tires. Hungarian innovators and researchers worked out an original, novel technology, which can exploit waste-rubber effectively and in an environment-friendly way by decomposing it and making the components adaptable for the industry. Gas, formed during the process and recycling waste-heat keep the energy needs of the system low compared to the size of the plant. Important to highlight that Hungarian innovators and researchers have worked out an original, novel technology, protected by Hungarian, EU and partly international patent, which they have been testing in industrial scale for six years at the Industrial Park of Balatonfűzfő. With the implementation of this project the Project Promoter would like to increase the system capacity of the current technology. With the investment – by August 2016, prospectively – the capacity of the plant at Balatonfűzfő will quadruple, increasing to 5,000 tons/year and will be suitable for the production of high-quality oil and carbon products.
Summary of project results
Pyrolysis, a process based on thermal decomposition, is one of the methods for the treatment of waste-tires. Hungarian researchers worked out an original, novel technology, protected by Hungarian, EU and partly international patent, which they have been testing in industrial scale for six years at the Industrial Park of Balatonfűzfő. The technology is presently utilized by Pannon Tyre Recycling Ltd. The technology can exploit waste-rubber effectively and in an environment-friendly way by decomposing it and making the components adaptable for the industry, chemical industry, cosmetics or pharmaceutical industry, or recycling them into tire manufacturing. If necessary, the end products can be used for energy needs. Gas, formed during the process and recycling waste-heat keep the energy needs of the system low compared to the size of the plant. Main characteristics and competitive advantages of the technology: • This novel technology has valid permits • It is a basic technology protected by extensive patents • It has proven to work in industrial scale (1,200 tons/year) with a well-documented experimental operation • The technology can process any kind of waste-rubbers or waste-tires • Only slight chopping is necessary: raw material is shredded into palmful pieces • Heat-transfer is highly efficient and consistent; thus, the power-consumption is low • The system is static, waste is not mixed in the reactor and there are no rotating parts • Waste-heat and pyro-gas are recycled • Quasi constant operation (periodically continuous operation) • A 330-workday, 24-hour, three-shift operation is maintainable • Decomposition processes can be controlled • The system has a robust structure with few moving parts (slight maintenance and reliable operation) • Largely automated, cost-efficient operation. Presently, three fractions are formed during the process: 1. The solid fraction is very fine carbon (carbon black) 2. The fluid fraction is carbureted-hydrogen pyrolysis-condensate (pyro-oil), which can be widely used in the chemical industry or for energetic purposes. 3. The third – gas fraction, which will be used to provide heat for the system itself after the development. 4. In case of processing steel-wire inserted tires–good-quality, recyclable waste-steel can also be retrieved.
Summary of bilateral results
The Project Partner is also responsible for quality assurance and control. This applies to the planning, implementation and reporting. The cost of the Donor Partner was financed by the Project Promoter.
