Provision of a delivery point and treatment service for street sweepings

Conwy County Borough Council (the “Council”) is procuring a service to recycle and treat street sweepings and gully waste collected by mechanical sweepers and gully tankers within the Conwy County area. The overall recycling and treatment requirement is anticipated to be around 2,800 tonnes of street sweepings and gully waste per annum (but no guaranteed minimum tonnage will apply). Tenderers should note that the quantities are indicative only. Actual waste inputs are dependent upon seasonal fluctuations and weather patterns that will effect street sweeping frequency. * The Council proposes to enter into contract for a period of 2 years with the option to extend for a further 12 months with the successful contractor. The anticipated contract commencement date is 01/12/2021. Street sweepings and gully waste collected from across the Conwy County area is collected by a fleet of authority sweepers and is tipped at the Council’s Materials Recycling Facility (MRF) at Bron y Nant Road, Mochdre. The material is then drained on site to reduce the overall water content in the material before it is transferred to the treatment facility. The waste is then loaded into 40 cubic yard skips each containing an average of 13 tonnes per skip, for onward transfer to the treatment facility. The Council is responsible for haulage transfer of the material to and from the treatment facility. The contractor will provide a service for the acceptance, processing, recycling, treatment and disposal of street sweeping waste and gully waste at a suitably licensed and permitted waste treatment facility. The method of treatment and disposal for waste is not prescribed and could involve various treatment methods such as mechanical separation, screening, silt treatment, Energy From Waste (EFW) incineration, anaerobic digestion, aerobic / In-vessel composting etc.. This is not an exhaustive list of treatment options. The contractor will be responsible for arranging outlets for the reuse, reprocessing, treatment or disposal of all material fractions arising from the waste, including any potential onward haulage costs. Currently all street sweepings and gully emptying’s collected by County Councils have the non-hazardous waste code: 20 03 03. The treatment service provided by the contractor must be compliant with the latest Natural Resources Wales guidance relating to the recovery of Street Sweepings and Gully Waste.
