Representatives from a Rotherham recycling company are due to appear in court today charged with corporate manslaughter over an explosion which killed an employee.
Father-of-three, Michael Whinfrey, aged 42, from Wickersley, was fatally injured in the blast at Sterecycle on Sheffield Road, Rotherham, on 11 January 2011.
His friend and co-worker Peter Davis, from Barnsley, was seriously injured in the blast but survived.
Sterecycle is charged with corporate manslaughter.
Three senior members of staff, maintenance manger Kevin Goss, operations director Paul Greenwell, and operations manager Steven Weaver are charged with health and safety breaches.
Goss is also charged with perverting the course of justice.
They will appear at Sheffield Crown Court this afternoon.
The plant, which used to treat up to 130,000 tonnes of waste a year, closed in 2012.
