Biffa’s Aggregate Treatment offers an innovative two-step process that 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, which minimises 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.
