To ask the Scottish Executive whether it plans to promote energy from waste by means of the integration of waste management with combined heat and power or district heating systems.
Scotland''s Zero Waste Plan is currently being finalised and will be published this summer. Implementing zero waste policies will encourage better resource utilisation through promotion of waste prevention; minimisation; re-use and recycling, and recovery where waste prevention, re-use or recycling is not feasible.
Consequently, waste recovery, including making use of thermal energy from waste processes, forms part of an integrated Zero Waste Strategy. Where energy from waste is used, it is important that it is used efficiently and to do so will invariably involve use of both heat and power generated from the plant.
SEPA has produced environmental permitting guidance to be considered by applicants who propose energy-from-waste plants. This makes it clear that new thermal treatment facilities should not impede recycling or waste prevention opportunities, and that they maximise the recovery of energy.
The practical implications of the guidance are that plants should only treat residual waste after all reasonable efforts have been made to extract recyclable materials, and that they should recover and use the energy derived from waste efficiently, including utilising heat in industrial applications and/or district heating systems.
