Complete Utilities Beat Blue-chip Companies to Win National Award with DUO Wash Plant.

30/11/11

National Joint Utilities Group (NJUG), the UK's only Trade Association for street works issues, have held their annual awards ceremony in House of Commons Members Dining Room, hosted by Louise Ellman MP (Chair of the Transport Select Committee). The awards were designed to recognise, promote and reward instances of best practice within the street works industry, with all winning entries to be used as examples of best practice and distributed throughout the industry.

Complete Utilities were one of four companies shortlisted for the NJUG Sustainability Award. The award recognises the company's work in maximizing the sustainable use of materials with its recycling wash plant which was supplied by DUO Equipment.

The Gloucestershire based firm, who provide excavation, backfilling and reinstatement services to the
utilities industry, made the decision to begin washing having previously dry screened their material. The driving force behind this decision was that the required standard of product is only available for six months of the year due to the weather when dry screening and even then the quality could not be guaranteed.

The Recycling Wash Plant
The two main components of the installation are the Powerscreen Aggwash , which is an award winner in its own right having picked up the Series Innovation Category Award at the 2010 World Demolition Awards, and the DUO Mobile Water Treatment Plant. The Aggwash provides for the first time rinsing, screening, scrubbing and sand washing capabilities on a single transportable chassis. Complete Utilities are running the Aggwash at 50-60 tph to process their material for backfilling and remediation purposes. DUO's mobile water treatment solution perfectly complements the Aggwash, eliminating silt and water being dispatched to a lagoon. The system, which is based on a centrifuge, is of compact size relative to its production levels which was a necessity in the design of the installation due to space restrictions on-site. This closed circuit system produces a very manageable material, the low moisture content of which is vital to Complete Utilities in ensuring it is workable for blending as clean soils as well as any surplus being transportable to, and accepted by, landfill and tipping sites.

Winning Washers
Complete Utilities, who were shortlisted alongside Balfour Beatty Utility Solutions, Laing O'Rourke and North London Gas Alliance, won the award with their wash plant which delivers a recycling rate of almost 100%. The benefits of this project, which were the backbone of the win, are financial, legislative and environmental.
Taking into consideration landfill costs, the cost of replacement primary aggregate for trench backfill and including the high capital investment of the new plant system, the company can still match the landfill and replacement aggregate costs when recycling trench spoil back into a high quality aggregate product.

Regarding legislation, the recycling operations exceeds the targets of ‘Halving Waste to Landfill by 2012' and also can realistically achieve Zero Waste to Landfill.
From an environmental perspective, the operation mean less landfilling of trenching spoil, less demand for primary aggregate and a reduction in carbon emissions as haulage distances are reduced; the carbon savings on the type 1 alone in the first 6 months would be in the region of 6 tons.

Speaking after receiving the award Steve said "It is great to get national recognition for the work we do - we're committed to environmental issues, minimising our waste and recycling as much as possible. This award shows how the hard work of my team and how our recycling plant makes a real difference. I'm delighted particularly given how tough the competition was. The investment in the Aggwash has definitely taken our business to the next level."

Lucy Binnie of Land and Mineral Management who advise Complete Utilities on environmental matters commented after the award was announced "This is testimony to the way that Complete Utilities have consistently striven to be the best in their field and do so in a way that is friendly to the environment. Steve and the team are real professionals who care for the environment and thoroughly deserve to be recognized in this manner."

DUO Sales Manager - Luke Talbot, who worked on the project added "It's great that the efforts of Steve and the rest of the Complete Utilities team have been recognized. We're pleased to be associated with their success and look forward to helping other customers achieve similar success in the future."
