A tyre-shredder that allegedly couldn't shred is at the centre of a bitter legal battle between two Cornwall-based recycling firms.
Tyre recycler ReTyre has claimed six figure damages against CHS Engineering for breach of contract.
ReTyre claims that CHS's sister company Advanced Recycling Solutions sold it a shredding machine that didn't work.
The manufacturer claims that ReTyre owes it outstanding costs and the repayment of a loan, which the tyre recycler denies.
CHS also alleges that ReTyre prevented prospective Advanced Recycling Solutions customers from viewing the shredder.
ReTyre's solicitors said that the company strenuously denied this claim because "they were never asked" by CHS Engineering to let people view the machine.
The case is due to be heard in Penzance County Court in September.
