A multimedia CD will be launched in Feb/06 introducing brick-makers & buyers to the significant benefits of using recycled glass as a fluxing agent. From Bottles to Bricks gives an overview of the practical & technical benefits of using the material to supplement traditional clay materials, such as Etruria Marl & Carboniferous Shale. The new CD has been produced by WRAP. Available to download from www.wrap.org.uk it reports the results of successful independent trials, involving testing to industry standards, conducted over the last 3 years by CERAM Building Technology. Results have shown that by adding between 5-10% glass powder, produced from recycled container glass, to the clay mixture, a range of benefits can be achieved. Depending on clay & kiln type, these benefits include reduced firing temperatures, increased throughput & lower emissions. Product improvements can also be achieved, such as greater compressive strength and enhanced frost resistance, in addition to the conservation of natural resources achieved by using a higher recycled content.
