Plans by an aggregate recycling company to more than double its capacity are causing concern over potential noise and disruption for people living nearby.
Ballast Phoenix, based at the former Union Carbide site at Beeley Wood, has applied to Sheffield Council for permission to process 135,000 tonnes of materials each year, up from 60,000.
There have been 16 objections from people living around Middlewood Road nearby.
Residents say they are unhappy about noise, dust and traffic.
Objectors said they would prefer hours of operation to be restricted to 8am to 6pm Mondays to Fridays – or for the site to be used as housing or light industry instead.

A meeting of Sheffield Council’s planning board chaired by Coun Alan Law will make a decision about the proposals on Tuesday.
