Recycling aggregates is not the only answer

It is suggested that the recycling of aggregates is not always the most sustainable or practical solution for a project. Britain has led the way in aggregate recycling with recycled and secondary aggregates making up 25 per cent of the aggregate market in 2007. When considering whole life costs, however, carbon footprint, material quality and availability make the picture less clear. Recycled aggregates are not always available at the right time in the right place and may potentially add to the carbon footprint of a project. The WRAP (Waste & Resources Action Programme ) Quality Protocol will set stricter standards for the proportion of 'other materials' which are acceptable within re-used demolition waste, Further, under new government proposals, a waste permit may be required to crush and screen demolition waste and operate a recycling facility. The cost of this may deter such activities at small scale sites and encourage haulage to larger operations, again increasing the carbon footprint.
