THE CHALLENGE
SUEZ UK is a recycling and resource management company who are known for providing innovative solutions throughout the UK and in 2010 it managed more than eight million tonnes of waste through a network of recycling, composting and landfill facilities.
Prior to the installation of the CDE recycling solution, all of the material which currently passes through the facility was taken directly to landfill.
THE SOLUTION
The 15 tonne-per hour road sweepings and gully waste recycling system provided to SUEZ UK includes a G:MAX, AquaCycle™ full water treatment system and a filter press.
Following extensive material testing there were several new pieces of equipment developed including a bespoke material specific feed hopper arrangement, along with a AggMax™ logwasher specifically designed to handle heavily contaminated material.
SUEZ UK also invested in CDE Preventative Maintenance programme through which assessments are carried out to ensure that all aspects of the plant are performing to optimum levels. CustomCare Manager at CDE, Martin Jackson comments, “Through a close working relationship, it was identified that further efficiencies could be achieved by replacing the Filter Press with a Centrifuge . The introduction of the Centrifuge allows the plant to more efficiently deal with the higher silt contents and cope with the variability in the feed material”.
In addition to the centrifuge, CDE has also successfully installed their new CO:FLO™ unit at the SUEZ UK Neatchells Lane site. The CO:FLO™ has been designed to improve water cleanliness and reduce chemical contaminants found in the clean water stream at recycling plants.
The CO:FLO™ is a multi-staged process which incorporates both mechanical and chemical treatments, ensuring the optimum water clarity is maintained
THE RESULTS
Through this recycling process, SUEZ UK are helping their clients to achieve their recycling targets while also reducing their requirement for virgin aggregate and increases composting volumes.
Up to 98% of the road sweepings that passes through the plant is recycled for use in various elements including sand, washed aggregate and compostable material which will be recovered from the incoming road sweeping waste using the latest technology.
This facility processes more than 40,000 tonnes of road sweepings each year which would have previously been landfilled.
