Making the most efficient use of all resources is an objective for the sector and an issue of increasing significance for customers and clients. The use of recycled and secondary materials in the aggregates sector has increased to an estimated market share of 28 per cent compared with ten per cent 20 years ago. The volume of supply has fallen as construction and aggregates markets have declined in the recession - less development means less demolition and a reduced supply of hard construction and demolition waste for recycling.
The industry has continued to work on the development of waste protocols with WRAP and the Environment Agency to ensure that materials are not prevented from being used in construction markets as an unintended consequence of waste regulations.
The cement industry has a strong record in this area and uses 94 times more waste and by-products than it generates, 1.3 million tonnes compared with 14,000 tonnes. The increasing use of biomass and waste derived fuels continues to provide substantial markets for waste materials, and in 2010 accounted for 38 per cent of all cement kiln fuels burned.
MPA recognises that Resource Efficiency is an issue of increasing importance to policy makers in the UK and Europe and is participating in a number of initiatives in this area. The minerals industry has substantial experience in Resource Efficiency issues and the related issue of Resource Security.
