Periodic Reporting for period 1 - TyRec process (TyRec process: Whole Tyre Recycling within 30 Minutes with Molten Zinc – towards a circular economy)
Reporting period: 2015-06-01 to 2015-11-30
As a 40,000 t/y plant is economic, a full scale plant may be build. Subsequently measures to upgrade the P-oil and rCB may be put in place to further increase the profitability of the plant. Hence upgrades can be assessed on materials actually produced by the real plant, rather than materials obtained from relatively controlled, small scale laboratory or pilot plants reducing the risk of any upgrade proposals for an operator.
The process uses molten zinc to recycle whole tyres within 30 minutes (no shredding or any other pre-treatment). The steel sinks in the zinc whereas the rCB floats on it. The rCB is removed with the pyrolysis gases from the chamber. The pilot plant testing and analysis of the products (P-oil, rCB and steel) showed that the product qualities are within expectations.
The main risk is the continuous operation of the plant – an operation, which can only be shown on a demonstration scale unit; minimised by pilot plant testing. The main objective of the study, establishing the technical, environmental and the economic feasibility of the TyRec process is achieved.
Social impact: The impacts of the commercial implementation of TyRec in the EU on employment, solid waste reduction and potentially CO2 reduction are major societal benefits. Local communities will appreciate new employment opportunities, both at labourer level and for engineers and plant operators (33 operating personnel per plant).
The main economic benefit of the TyRec technology is that it is an economic tyre pyrolysis process with an IRR estimated to be 29% for a 40,000t/y plant with larger throughputs resulting in even higher IRRs. As a result the unique selling points of the TyRec technology are:
• Economic, IRR ~29% greatly exceeding the user requirement of 15% IRR for new technologies. Other unique selling points backing up the IRR of 29% are:
o Ability to treat whole tyres eliminating the costly operations: shredding, granulating, steel removal.
o Highly efficient treatment due to direct heat transfer with molten zinc (20 min rather than 2-4 hours).
o Availability of accessible markets for all the products from a TyRec process.
