Waste Management (Grit, Screening and Iron Sludge

The procurement of Waste Management for Grit, Screening and Iron Sludge as per below:

AWS has elected to split the existing waste stream of Grit, Screenings and Iron Sludge into

three separate lots:

1. Grit (Lot 1)
2. Screenings (Lot 2)
3. Iron Sludge (Lot 3)

The above three lots are key areas where a significant tonnage is output from AWS'

operational sites each year. By splitting these lots, AWS is attempting to identify innovative

alternatives to disposal via landfill which are available within the market.

Lot 1:

The Waste Management partner is required to provide skips or containers to collect the Grit

as it is output from the waste recycling process. Following this, the Waste Management

partner provides haulage services to transport the waste to AWS grit hubs for recycling by

AWS.

Lot 2:

The Waste Management partner is required to provide skips or containers to collect the

screenings as it is output from the waste recycling process. Following this, the Waste

Management partner provides collection and haulage services to transport the waste off site

to a disposal site. Currently, this is landfill sites, however this does not align with Anglian

Water's sustainability goals or Circular Economy Strategy therefore a disposal option higher

on the waste hierarchy would be preferable.

Lot 3:

The Waste Management partner is required to provide skips or containers to collect the iron

sludge as it is output from the water treatment works process. Following this, the Waste

Management partner provides collection and haulage services to transport the waste off site

to a disposal site.
