Biffa's Aggregate Treatment offers an innovative two-step process which sifts and then washes street sweepings and gulley suckings, recovering 99% of all material taken to our facilities. Highly efficient and very cost effective, it improves local authority recycling figures and minimises the amount of waste going to landfill - minimising landfill tax.

Recovered materials include secondary aggregates (sharp sand and stone), which are sold on site for reuse in non-structural applications, and glass, metals and green waste (twigs) which are sent for further recycling.
