The company announced this week that the Environment Agency confirmed in November 2012 that papermaking ash produced by Aylesford Newsprint Ltd meets the End of Waste test and can now be supplied to block manufacturing customers as a raw material product rather than as a waste to replace cement.
Aylesford Newsprint recycles recovered fibre used newspapers and magazines – to manufacture Renaissance Newsprint.
Fibrous
In the papermaking process a paper crumble is produced which is a light fibrous material made up of paper fibres, clays and other materials washed out from the pulping process.
The paper crumble is burnt in an on-site combustor to generate both energy and papermaking ash. The papermaking ash is rich in calcium oxide and can be used to partially replace lime or cement in other manufacturing processes.
A statement from Aylesford explained that the benefits of the change in status from waste to product for papermaking ash customers, include the ability to accept ash without the need to have a waste permit or needing to consign the ash as a waste.
And, it added: As papermaking ash makes a good partial replacement for cement, Aylesford Newsprint has regularly supplied a number of customers with this material since 1995 and the new product status of the ash now makes it more accessible to others.
