Grays Recycling Services purchases a New HAAS TYRON following supply of Kiverco Plants Grays Recycling Services is a family-run business providing waste services across Fochabers, in the Scottish Highlands. Starting out as a metal recycling business in 2004, GRS has since expanded their service offerings to include skip hire and commercial trade waste services. GRS uses a range of processes to recycle and extract value from their incoming waste streams. A large percentage of their waste is generated through their skip hire and commercial waste services. This waste contains various valuable materials that can be reclaimed through their picking station leaving a clean aggregate product. Late 2017, GRS contacted CRJ Services for a solution that would clean up their trommel fine material, removing any metal, and any other material that would negatively affect the ‘Loss of Ignition’ (LOI)* testing results. After taking GRS personnel to various sites in London, along with Kiverco personnel, to showcase the Kiverco Stand Alone Fines Processing Systems, GRS bought such a system from CRJ Services which was installed in June 2018. This system comprises of a Hopper which -40mm Trommel Fines is fed into, an incline belt and over band magnet (removing ferrous material), a Spaleck single deck Flip Flow screen, removing -10mm material. The <10mm fraction is sent to landfill with a 6 – 8 percent LOI, qualifying it for the lower rate of tax. The 10 – 40mm light fraction is sent as an RDF material to a waste to energy plant, with the heavy fraction being sold as a recycled aggregate product. The 10 – 40mm heavy material is made up of aggregates which are further processed onsite. Following the successful commissioning of their fines clean up plant, GRS returned to CRJ Services in 2019, looking to replace their existing diesel, mobile trommel with an electric static solution. This transition to an electric trommel forms part of GRS’ wider agenda of making their processes more sustainable and environmentally friendly. CRJ Services suggested the Kiverco 615 Trommel with integrated Hopper design, which is robust enough to deal with their abrasive commercial and skip waste. The static trommel was incorporated

into their existing plant; a Bruce 5 bay double sided Picking Station with over band magnet in August 2019. The Kiverco Trommel screens out the <40mm product, which is ejected from the building, allowing for easy transfer to their Kiverco fines clean up plant. The >40mm oversize material is then fed onto their existing Bruce picking station for the removal of commodities and metals Having built a great relationship across two successful projects, GRS once again returned to CRJ Services for a third time in 2021, requiring a versatile mobile shredder to replace their aging Powerscreen Powershredder 1800. “It has been a pleasure to deal with Grays Recycling over the years. Having worked with them for over 6 years, it has been great to witness their growth, and to be able to supply quality equipment to meet their requirements. I look forward to working with them again in the future.” said Damian Casey – Area Sales Manager at CRJ Services.
