Screenings from Wastewater processes Recycling/ Disposal

Tender description

As a Water and Wastewater service provider, United Utilities produces circa 13,000 tonnes of Screenings from its Wastewater Treatment works that requires disposal. Screenings are the bulky solids mechanically removed from wastewater (sewage) flows during the preliminary stage of treatment. They are made up primarily of sanitary products and their packaging, applicators, wet wipes and cotton buds and also includes some plastics, paper and wood and a small organic fraction which comes from leaves branches etc that enter into sewer systems. The EWC code for screenings is 19 08 01. Screenings are removed at two stages preliminary treatment where most sites screen down to 6mm in two directions, (there are some sites now screening flows down to 3mm) and before sludge treatment, we differentiate by describing these as sludge screenings, they are under the same EWC. The Company are seeking alternate routes in the recycling/ disposal of its screenings and would like to speak with suppliers who could have a potential solution for this waste. The Company has carried out various trials and routes for disposal / recycling of screenings in the past which can be found within the attached ‘Screenings additional information’ document
