The Confederation of Paper Industries has rejected media reports that it sees a link between commingled collections and low quality.
In a statement the organisation said: Recovered paper and board from commingled collection systems can and does meet the quality requirement for the global paper and board industry when run through materials recycling facilities that have clear systems to manage the communication, inputs and sorting processes.
Good quality material is necessary to avoid economic and carbon inefficiency, the CPI said. This need for high material standards meant that poor quality paper would be the first to suffer in a buyers market, according to the CPI.
MRF quality was discussed at a recent stakeholder meeting organised by the Waste & Resources Action Programme.
Commenting on the debate, MRF operator Greenstar UK chief executive Ian Wakelin said: If you process material through an excellent process, you will get high quality product that can be sold anywhere in the world.
A CPI spokesman said: CPIs position is clear. We support any method of collection and processing that meets these quality aims - it is all about quality and competitiveness.
But a suggested link between low quality material and commingled collections has been highlighted by the Campaign for Real Recycling. In recent letters to English and Welsh Environment Ministers Jane Kennedy and Jane Davidson, the campaign warned against turning to single stream collections during the tough economic climate.
