The cement industry has outlined how concrete recycling can be increased and is pushing for an ultimate goal of ‘zero landfill’ for the product.
In its report the Cement Sustainability Initiative (CSI), an 18-strong association of cement producers and part of the World Business Council for Sustainable Development, says more must be done to recycle concrete, which, at 30 billion tonnes a year, is the world’s second most consumed material after water.
In some countries, such as the Netherlands and Finland, full recovery of concrete is achieved, but in most parts of the world - especially in Africa but also in developed countries including Spain and Portugal - efforts to recycle construction and demolition waste are minimal.
The CSI recommends that governments and stakeholders publicize data on construction and demolition waste and develop reliable statistics, that they develop economic incentives and legislation to promote concrete recycling, and that they set targets for the use of recycled concrete in the road construction and building industries.
The CSI, whose members include Holcim and Italcementi, accounts for 30 per cent of the world’s cement production. About 95 per cent of manufactured cement is used for concrete manufacture.
