THE Sheehan Group has invested in upgrading its CDE Global wet processing plant to produce higher quality recycled sand.
The recycling and sustainable construction company made the significant investment in adding another wash to the system to produce higher quality sharp sand. The Sheehan Group is one of the first companies in the UK to introduce the new technology.
CDE integrated its patented Counter Flow Classification Unit which is used for density separation to the existing system. This enabled the removal of fine organics, lightweights (0.063mm to 5mm) and the maximum amount of silt from the coarse and fine sand. The process improved the quality of the recycled sands produced.
Tara Sheehan, finance director at the Sheehan Group, said: “We are always looking at how new technology and innovations can help us be more sustainable and offer more environmentally-friendly recycled products onto the market.
“By working closely with CDE we have been able to add an additional wash to the wet processing plant which means we can produce an additional high-quality sharp sand for contractors to purchase in bulk. Our investment further supports sustainable construction and the Circular Driven Economy in Oxfordshire which is crucial to our environment.”
Sean Kerr, chief operating officer at CDE Global, said: “CDE were delighted to work with our repeat and valued customer, the Sheehan Group, on further improving the quality of their recycled sands. Being the innovators the Sheehan Group are, they wished to explore technology which hadn’t been used in this application previously. We were able to integrate our patented CFCU technology to increase density separation.
“The improved-quality sand that is now being produced has a wide range of high-value applications in the construction trade. The Sheehan group use these sands in their own products and are true champions of the Circular Driven Economy.”
The Sheehan Group has operated its CDE Global wet processing plant for seven years at its site at Dix Pit, Stanton Harcourt, Oxfordshire. The water treatment facility is used to wash construction and demolition waste, destined for landfill, turning it into reusable aggregate. The process reduces demand on the environment for natural resources, by re-creating high-quality secondary aggregate and sand from waste. In this period, it has saved 775,000 tonnes of construction and demolition (C&D) waste from landfill, by reprocessing it into recycled aggregates. The 775,000 tonnes saved is the equivalent of 1,700 Boeing 747 planes at maximum take-off weight.
