Denby is a household name. It has been making pottery in Derbyshire for over 200 years and has moved on from the production of the salt-glazed pottery of its early days to the easily recognisable kitchen and tableware which we are familiar with today. Recently, the company has developed a challenging zero waste to landfill policy to improve its sustainability. Nottinghamshire Recycling Ltd offers a range of waste sorting and recycling services from its site in Worksop. Construction waste provides products for aggregates markets, while the company’s on-site (MRF) facilitates the recycling of 80 per cent of material. Once recyclables have been removed, remaining waste is treated to manufacture a refused-derived fuel.
Denby had explored a recycling solution for its large quantities of ceramic waste, but due to the variety of materials involved and the sharp nature of some of the waste, it had been unsuccessful.
NISP Network Involvement
NISP Network and Denby first met at an event in Derby, during which NISP was made aware of the problematic nature of the company’s ceramic waste, which was being landfilled at substantial cost since Denby had been unable to find a more sustainable provider willing to accept it. After consulting its bank of members and industry contacts, NISP made enquiries among potential synergy partners and had compiled a list of four interested companies within less than a month.
NISP Network proposed four potential service providers to collect and recycle the ceramics waste. Denby chose a local company, Nottinghamshire Recycling Ltd, which recycles the ceramic waste into aggregates for the construction market and was able to use its on-site materials recovery facility (MRF) to sort additional waste materials such as cardboard and plastics. The resulting partnership with Nottinghamshire Recycling Ltd proved even more beneficial than expected, since the company was also able to offer a service for Denby’s additional materials. The synergy has been fundamental in Denby achieving its zero-waste-to-landfill policy.
• Cost savings totalled £10,000, with additional sales of £110,000
• The synergy resulted in a landfill diversion saving of 3936 tonnes – 3880 tonnes of ceramics and 56 tonnes of general waste
• CO2 reduction of 596 tonnes.
“My experience of working with NISP has been very positive. They are extremely helpful and supportive and the resulting agreement has successfully diverted all of our process waste away from landfill.”
