The Waste & Resources Action Programme, based in the UK, along with BSI, have published a specification sheet to provide assistance and guidance for processed glass for use in some secondary end markets. The product is being called PAS 102, is publicly available.
PAS 102 provides quality requirements for recycled glass suitable for ceramic sanitary ware production; as a fluxing agent in brick manufacture; in sports turf and related applications; as water filtration media and as an abrasive.
For each market, PAS 102 details color, contamination limits, particle size requirements and appropriate test methods for the processed glass.
PAS 102 was developed in consultation with a wide variety of stakeholders and builds on PAS 101, which was published last year and specifies quality requirements for recovered container glass. PAS 101 has been successful in promoting best practice among collectors of glass cullet - helping them to achieve the higher grades of the specification - and can be used as a basis for supply contract negotiation.
“The container industry cannot consume all the available recycled container glass, so it was important to develop PAS 102 for secondary end markets,” said Jacks Guinness, Materials Project Officer for Glass at WRAP. “We hope the new specification will encourage further development of these innovative end markets.”
“PAS 102 gives both re-processors and end users of recycled glass in these secondary markets the information they need to develop solutions for their individual applications. It is our hope that PAS 102 will encourage industry to look to recycled glass for a practical alternative material.”
Copies of PAS 102 and 101 are available, free of charge, by calling the WRAP helpline on 0808 100 2040. Summaries of both specifications can be found on the WRAP website www.wrap.org.uk.
