The Quality Protocol for the Production of Processed Cullet from Waste Flat Glass

6th December 2016

This quality protocol, which only applies in England and Wales, should make it easier to recycle the 6.6 million domestic windows that are replaced every year, into products such as filtration media and new windows.

Key points
Re-melting cullet uses 25% less energy than making glass from raw materials
Each tonne of cullet also saves 1.2 tonnes of raw materials from being extracted

Overview

Overview

Produced in consultation with the UK glass industry and other key stakeholders, this QP will provide collectors, recyclers and processors with a clear set of practices and standards designed to increase both the volume and quality of flat glass cullet being sold to manufacturers.

As part of this guidance, WRAP provides a report on good practice and specifications for flat glass recycling, as well as detailing the benefits of good practice in flat glass recycling.

Flat glass specification

This specification is for flat glass cullet which is delivered to the glass manufacturer for use in the manufacture of new flat glass.

The purpose of the specification is to provide cullet processors with guidance on the quality of cullet required by the glass manufacturer.

It is for guidance only as each manufacturer may have their own requirements depending on site equipment and the final product.
