Waste management company Severnside Recycling has teamed up with organic waste management specialist Envar to find a solution to Severnside’s de-inked paper sludge produced at sister company St Regis’ Hollins Mill in Darwen, Blackburn.
Envar will take 26,000 tonnes of paper sludge from the paper mill each year. This will then be used as animal bedding, land restoration and agricultural fertiliser.
Severnside, which is owned by parent company DS Smith and includes St Regis, has a no-landfill ethos. Before working with Envar, the waste from Hollins Mill was spread on farmland as an organic fertiliser, but Envar will now be able to go to a wider range of uses.
Severnside commercial director Mathew Prosser said: “Envar is able to offer some interesting solutions which are seeing the waste from our companies’ mills being put to excellent reuse. With our own clients, we pride ourselves on developing innovative solutions to avoid landfill, so working with Envar means we can ensure that our own waste practices are just as sustainable.”
Envar development director Andrew Urquhart added: “De-inked paper sludge offers a number of recycling options. The paper crumb from the mills is ideal as a bedding product because it has low moisture content and no odour, 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.”
