London building materials supplier S Walsh has signed a long-term supply deal enabling it to provide construction companies with recycled aggregate.
The deal is with Imerys Minerals Ltd (IML), a china clay producer in Cornwall that generates millions of tonnes of by-product annually, much of which can be processed into secondary aggregates, also known as stent.
“It has always been our long term vision to secure a sustainable resource to build a greener London,” said S Walsh commercial director Westley Pickup. “We have undertaken extensive research and know that these products can be used more widely for infrastructure, residential, commercial, education and health construction projects.
“Secondary aggregate from china clay waste meets the requirements of sustainable building in the UK. There is a huge lack of understanding of availability and potential for this ‘secondary’ resource and we expect that through our commercial relationships we can share what the possibilities are.”
Plans have been drawn up for both rail and sea terminals to reduce lorry movements. S Walsh also plans new manufacturing facilities for sustainable construction products.
“This will represent a major investment in state of the art low carbon production plants which will be the most advanced in Europe whilst providing a new major sustainable employer in manufacturing within the in the region,” Mr Pickup said.
