New Glass Specification From Wrap Aims To Develop Secondary End Markets
WRAP (the Waste & Resources Action Programme) and BSI have published the Publicly Available Specification 102 (PAS 102) to provide guidance for processed glass for use in selected secondary end markets.
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 colour, 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
WRAP has also published a new report to be read in conjunction with PAS 101 - ‘Recovered container glass: Development of test methods and inorganic contamination limits'. At the time PAS 101 was originally prepared, there was insufficient data available to determine the limits on inorganic contamination for recovered container glass and a statement was included that any inorganic contamination limits would be ‘subject to agreement between processor & collector’.
This issue has been addressed with this latest research, undertaken by Glass Technology Services (GTS), which looks at establishing a suitable test method and setting potential limits on inorganic contamination for recovered container glass.
