Using recycled glass as pipe embedment material
Tests and trials have been conducted to assess the suitability of glass fines as a replacement for virgin sand in some construction applications, with the results presented in the report and fact sheet below.
The glass fines were tested against a number of environmental guidelines to assess the presence of contaminants. The low levels of metals and organic material met the engineering specifications of the Water Services Association of Australia.
Following these tests, glass fines were used in field trials on two construction sites as an alternative to natural sand in the embedment of water mains and residential sewerage pipes. Workers using the material reported that it handled as easily as natural sand and posed no greater problems of odour, skin contact or dust than natural sand. The EPA has issued a resource recovery order (PDF 75KB) and exemption (PDF 56KB) to enable the lawful land application of recovered glass.
The report examines potential safety issues in detail and includes quality control procedures and a sample material safety data sheet for glass fines.
