Cambridgeshire Waste PFI

Amey has a long-term partnership with Cambridgeshire County Council, delivering its £731million, 28-year waste processing and recycling contract. This long-term contract was let as a Private Finance Initiative (PFI) project.

Through the contract we operate a number of waste technologies to deal with residents’ household waste, including a Mechanical Biological Treatment (MBT) plant and in-vessel composting facility, as well as operating three waste transfer stations at Waterbeach, Alconbury and March and managing the operations of nine Household Recycling Centres in Cambridgeshire.

To reduce waste going to landfill all of Cambridgeshire's 'black bag' household waste is taken to the MBT facility, where items can be extracted by our machines for recycling and other uses, before the remainder is made into a compost-like material. This significantly reduces greenhouse gas emissions compared to sending the waste straight to landfill and saves money as landfill is becoming more and more expensive.

The county's kitchen and garden waste is taken to Waterbeach to be composted. The in-vessel composting process allows us to compost garden trimmings, fruit, vegetable, meat and fish waste, which is shredded and put into 'vessels' where it reaches a temperature of 60°C (which kills off disease-causing organisms so that it conforms to European Animal By-Products Regulations). Within six to eight weeks soil conditioner is produced that is used by local farmers. This soil conditioner can be collected in bulk (free of charge) from the Waterbeach site or purchased for £2.50 a bag at the Household Recycling Centres (apart from Milton).
