Esher 7 November 2017: Keltbray Environmental, which is part of Keltbray Group, and is dedicated to the recovery, treatment and reuse of construction materials, has won a Green Apple Gold Award. The award was presented at the Houses of Parliament and was won in the Building & Construction Waste Management category for work Keltbray carried out as part of the London Bridge Station redevelopment to divert waste from landfill.

Keltbray has been working on the award-winning redesign programme at London Bridge since 2012, to help facilitate new platforms and a new concourse, and was presented with the award for its treatment of multiple waste types from the major redevelopment site. These included soils, track ballast and concrete, which was treated and recovered; and so diverting it from landfill and allowing it to be used at restoration sites.

“We were able to treat more than 22,000 tonnes of material from London Bridge just in 2016, including all hazardous and non-hazardous soils and track ballast, which we barged to suitable restoration sites following treatment. We also ensured 1,000 tonnes of concrete from the site was crushed at our treatment facility and suitable for reuse in new developments. This diverted waste from landfill, and using the barges also saved more than 1,000 lorry journeys and reduced the carbon footprint of this contract considerably.

“Barges produce 64% less CO2 and 15% less NOx than a fully loaded EURO 3 compliant 8 wheel tipper truck. They are also safer and less noisy than lorries and allow us to transport much more material per movement,” explained Managing Director for Keltbray Environmental, Dr Cliff Burton.

“This contract was a particular challenge as the redevelopment site had minimal space for onsite stockpiling of material. We also had to work to very tight deadlines to meet requirements on site. It was a major aim to pre-classify as much of the soil and waste types as possible, so the waste could leave site quickly. This required a rigorous sampling programme that was implemented to allow for individual analysis of each of the railway arches on site, as these all had unique contamination profiles. It also meant we had to take extra care to manage the material waste and ensure it was correctly classified, as the mis-classification would have had significant environmental and financial consequences,” Cliff concluded.

The Green Apple Environment Awards were launched in 1994 by The Green Organisation to recognise, reward and promote environmental best practice around the world. They are presented by The Green Organisation, which is an international, independent, non-profit, non-political, non-activist environment group, to recognise, reward and promote environmental best practice by companies, organisations and Governments around the world.
