In the UK, waste management company Severnside Recycling and Envar, a specialist in the recycling of organic wastes, are co-operating to develop alternative outlets for waste produced during the paper making process. Severnside and its parent company DS Smith, which includes St Regis, have a no-landfill ethos.
The partnership will see de-inked paper sludge from St Regis’ Hollins Mill in Darwen, being used for a range of applications including animal bedding, land restoration and agricultural fertiliser. Envar will handle around 26,000 tonnes/year of paper sludge from the Hollins Mill.
“De-inked paper sludge offers a number of different recycling options,” says Andrew Urquhart, Development Director at Envar. “The paper crumb from the mills is ideal as a bedding product, offering farmers a cost-effective and sustainable alternative to intensively farmed hay and straw. Furthermore, paper sludge contains excellent organic matter, provides plant nutrients and can be used in restoration projects as an ingredient in manufactured soil helping to grow new trees and providing a complete closed loop when the trees are harvested to produce paper.”
Before working with Envar, the waste from the Hollins Mill was spread on farm land as an organic fertiliser, but the partnership with Envar means that the waste can go to a wider range of uses. The paper sludge from St Regis and DS Smith’s other mills continues to be used on local farm land.
