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 Services over the years. Having worked with them for over 4 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.”

As GRS is located in a remote part of the UK, they must ensure their lorries are at maximum weight in order to efficiently transfer their waste to waste to energy plants.


To reach the maximum weight in their lorries, the material must be shredded down to allow for a more compact load. This reduces the number of miles driven and in turn reduces their carbon footprint.


As GRS is a multi-waste processor, the required shredder needed to be able to produce a consistent particle size across various materials to meet the required specification of the waste to energy plants. CRJ Services suggested the HAAS TYRON and brought the TYRON 2000XL 2.0 to site for a demonstration.


“We have been delighted with the service received from CRJ Services. We received a demonstration of the HAAS TYRON shredder before we purchased, and this certainly helped us make up our mind.  The machine was delivered on time and CRJ provided in-depth training and demonstration which was very much appreciated.”

The HAAS TYRON has four shredding programs: wood, green waste, general waste and a fourth customisable setting. This, coupled with the ease of maintenance provided by the TYRON, makes it the ideal machine for GRS.


“We are very pleased with the performance of the HAAS TYRON. It has performed all tasks well and to requirement so far; a very reliable machine.”

“The relationship with GRS has been built on trust. We understand their processes and requirements, and they trust us to provide them with the best solutions in the market. It is great to see a family-run business such as GRS going from strength to strength, and it’s a privilege to be able to support them with our services.”
