Saica Paper UK Limited (2012)
The energy recovery boiler plant at the SAICA PM11 site in Partington (near Manchester, UK) serves to provide the thermal treatment of waste from the cardboard manufacturing process and is designed in accordance with the requirements of the Waste Incineration Directive. The fuels concern rejects from stock preparation and sludge (fibrous sludge and bio sludge) from the effluent water treatment plant, as well as natural gas and bio gas for the start-up and back-up burners. The heat recovery boiler generates steam, which is used in the cardboard drying process. The plant is able to save up to 17,000,000 m³ of natural gas per year through the energy recovery of waste resources from the paper mills.
