Sweeping up cost savings

Q: What is your product?

The CDEnviro system for recycling road sweepings and gully waste.

Q: How does it work?

It is a dual-stage washing and recycling system for solid-liquid mixtures that need to be classified or dewatered. It can reclassify waste, moving it from ‘non-hazardous’ to ‘inert’ for disposal. This provides significant savings in landfill tax and often reuse.

Q: Where would it ideally be used?

The system is available in a variety of configurations, from portable units designed to handle smaller capacities up to fixed plant installations for central recycling facilities.

Q: How is it different?

It can be tailored to suit the specific requirements of each recycling operation. The system uses a combination of attrition, upward flow classification, effective dewatering, multiple product separation and full water treatment.

Q: What are the benefits?

It has the potential to reduce waste to landfill by up to 85%. Washed grit is suitable as a non-structural fill secondary aggregate. A mobile plant option can offer processing at a number of sites, and the return on investment is typically within two years.

Q: Where has it been used?

We have provided solutions for a number of waste management companies. A high proportion of road sweepings from across the Midlands are now recycled rather than sent to landfill following the installation of a plant at Sita UK’s Neachells Lane facility, Wolverhampton.

Q Any savings?

Ninety-eight per cent of the road sweepings that pass through the Neachells plant will be recycled, and 300,000 tonnes will be diverted from landfill as a result of the installation. This will deliver savings of £10m over seven years, with recycling rates of the participating councils being boosted by around 3%.

Q: What about maintenance?

A dedicated team provides customers with an assigned account manager, operator training, regular plant audits and a recommended spares list to have in stock to avoid downtime.

There are also service contracts available, tailored to customer requirements from preventive maintenance contracts to fixed cost asset care programmes.

Q: What is its life span?

Fifteen years and longer.

Q: How is it future-proofed?

The modular design of the system enables future items of equipment to be added with ease.

Q: Any future applications?

The system can also be installed at a MRF to recycle trommel fines.
