Following the installation of the DMax grit recovery and recycling plant at the Coleshill Seeage treatment works in Birmingham, England there has been a video produced by CDEnviro to demonstrate the efficiency of the plant in reducing waste to landfill volumes.

As previously reported the Dmax plant has helped Severn Trent to reduce their waste to landfill volumes arising from a variety of waste streams through effective material processing and classification of the constituent materials. Within the various wastes being processed by the DMax plant there are a number of them which can be re-used following the effective washing and classification steps that they are subjected to.

The primary material being treated by the DMax installation at Coleshill Sewage Treatment Works is inlet works grit. After being passed through the DMax system a variety of materials are available to Severn Trent.

Firstly, and in the largest quantity is the -5mm grit, sand and small gravels which has been washed and dewatered to such an extent that Severn Trent are able to use the material on their own civils projects in applications such as non-structural fill or pipe bedding. This provides a suitable further use for material that was previously all being disposed of in landfill.

In addition to this there is also a quantity of larger mineral material that once classified is being moved on to the construction and demolition waste recycling market where it is being further classified. Once again, this material was previously all destined for landfill.

Meanwhile the waste water from the processed material is returned to the treatment plant for further processing while the rag and organics are the only materials now destibed for landfill - these typcically represent around 10% of the total volume of material processed.
