RSRL Integrated Waste Strategy - Issue 5- Oct 2012.pdf

NOT PROTECTIVELY MARKED321. A forward programme has been prepared for utilisation of the route used by Harwell andit is envisaged that the first shipment of waste from Winfrith will take place by January 2013.Whilst RSRL already has an EA permit to dispose of HV-VLLW (material with an activity of4Bq/g) to the landfill. An application for arevision to the existing permit has been drafted and is due to be submitted in the early partof 2013.7.1.3.5 LLW Organic Sludges322. Organic sludge arisings comprise mainly of sewage sludges from the Active LiquidEffluent System (ALES), which are used to treat active foul water arisings prior to seadischarge. These wastes are currently segregated, dewatered and packaged prior toincineration at an off-site facility. There is an ongoing generation of these wastes.323. The relatively small volumes of active sludge wastes from the ALES plant means thatthere is currently no practicable viable alternative to the existing strategy of incineration.Given the close geographical location of the currently utilised incineration facility and thehigh levels of abatement fitted to the incinerator, use of an on-site incinerator (permanent ormobile plant) as an alternative would offer no benefits.324.
