Recycling company Unimetals, which has dozens of sites across the UK, has filed for liquidation.
The company's head office is in Stratford-upon-Avon, and has sites scattered around the country, including London, Halesowen, Staffordshire, Greater Manchester and Devon.
It is unclear when the firm will go into liquidation, and how many jobs are at risk.
"We have worked tirelessly to explore every possible option to secure new financing for Unimetals Recycling (UK) Ltd, with the aim of meeting our financial obligations and safeguarding the future of the business," a spokesperson said on Monday.
