This paper provides guidance on the overall development of landfill sites, encompassing landfill design, construction and operational practice. The guidance is set in the context of the Government's commitment to sustainable development and the developing strategy for sustainable waste management. The guidance emphasizes an engineering approach to landfill design and construction based on site-specific risk assessment, underpinned by quality management and good operational practice, to achieve a high standard of implementation and environmental protection. A fold out user guide is provided to assist the reader through the stages of landfill design and operational practice, together with a full index listing for individual topic areas.
