CDEnviro improves Recycling Plant efficiency at SITA UK

Posted: Tuesday 21st April 2015

SITA UK has recently upgraded the CDEnviro recycling plant at their Wolverhampton facility by introducing a centrifuge to increase the volume of silt that can be processed by the plant. The introduction of this technology has enabled SITA UK to help their clients achieve their recycling targets.

Since its installation in 2012, SITA UK have been processing road sweepings and gully waste recycling at Neatchells Lane, Wolverhampton through the CDEnviro system. The 15 TPH road sweepings plant includes a bespoke feed hopper arrangement and a high attrition system designed specifically to handle this heavily contaminated material. Through this recycling process, SITA UK can help their clients to achieve their recycling targets while also reducing their requirement for virgin aggregate and increases CLO (Compost Like Output) composting volumes.

SITA UK also invested in CDEnviro 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 CDEnviro, Fergal Campbell 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, CDEnviro has also successfully installed their new CO:FLO unit at the SITA 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

Following a trial period, the CO:FLO has proven to improve water cleanliness on this type of waste stream by 300-400% in comparison to the previous system. This design is currently pending patent.

Commenting on this system improvement Martin Bladon, Project Development Manager at SITA UK said “We continue to work with CDEnviro to improve our processes and take on board their advice as the experts in recycling technology”
