D&E Roberts Ltd is a Leatherhead-based waste management company.
Their core business is processing skip waste to create refined materials for re-sale.
Their source materials include hard-core, metal, cardboard and wood.
D&E Roberts recently called in WRT Waste Recycling Technologies Ltd because they wanted help in improving the financial return from their Trommel screening and fines separation.
One key aim here was to reduce the amount of fines going to landfill.
Recent changes in legislation include enhanced emissions regulations, which require UK recycling providers to determine if the fines they’re making are active or non-active.
In terms of disposal, there is a substantial difference in tax allowance per tonne, between the two.
New additions to their existing recycling system from WRT gave D&E Roberts a secondary screening process which includes fines collection from under the existing SWT.
Before the upgrade, the Trommel drum was fitted with 30mm screens however, now with the interdiction of a Bivitec screen at 10mm, this client has seen 40% less fines to landfill at the cheaper rate.
After testing, the results showed that Loss of Ignition requirements in the fines had been achieved on average 5.5% treated; meaning significant savings in disposal costs.
Currently D&E Roberts Ltd processes around 200 tonne per week and with a saving of around £87 per tonne, this will add up significantly over a 12 month period.
Heavy (and light) metal
WRT also helped this client extend the benefit from their metal recycling.
To support this we installed an Overband magnet to pull out ferrous metals and these +10/50mm materials include nails, screws and other smaller metal items.
Materials then pass under a Screenpod 1200 AirVac unit which sucks off any lighter residue which is then discharged via steel ducting into the existing lights bay.
The lighter materials at this point include plastics, polystyrene, wood and cloth; all of which are used to make a fuel for burning.
Any remaining materials at the end of this now fully comprehensive process, are used as hard-core. This is then processed into a 6F5 material and sold.
By reducing the small particles in the hardcore this process has also led to a reduction in labour in the cleaning up of the final product.
The only material therefore now going to landfill is highly refined fines.
With significant landfill reductions, reduced costs and improved re-sale options, the result for WRT, was a very happy client.
You may be able to benefit
If you run any type of screening and recycling process it is likely that you’ll be able to extract additional financial benefit from your input materials.
