Trommel answer to landfill space


UP TO 70 per cent of material excavated from an old landfill has been converted into reusable or saleable material thanks to a new Powerscreen Trommel 615.

The materials had previously been dumped untreated into the 20-acre site owned by Derry-based City Industrial Waste.

But with landfill fees rising and strict limits on new sites the company decided to sort the waste to extend the site's volume and working life.

The Trommel has been used to process up to 115 tonnes of material per hour in dry conditions (90 tonnes in the wet), using a 20 mm screen aperture.

Of the materials that are recovered, 60 per cent is topsoil,30 per cent hardcore and 10 per cent lights.

As well as freeing up more landfill space there is the chance of onward processing and sale.
