Viridor has invested in some of the most advanced processing equipment in the recycling industry in the UK. It has made a major contribution to the environment by helping its customers recycle more, and significantly reduce ‘waste to landfill’.
The Viridor site in Sheffield is one of the most advanced glass recycling plants in the UK, producing a high quality glass product ready for re-manufacture. The facility processes over 3000 tonnes of glass from household and commercial glass collection points each week.
Whilst Viridor’s high performance primary separation and sorting processes at the Sheffield recycling facility ensure the bulk of unwanted contaminants (including plastics, metal, wood and paper) are removed early in the process, smaller metal fragments often remained in the glass until the end of the process. These metal fragments – in particular wired glass – were causing problems at the glass re-processors during the melting process.
To solve the problem, Eclipse Magnetics specified an Artemis tunnel metal detector. This was placed “in-process” after the primary sorting and crushing processes. As material passes through the detection tunnel, an electromagnetic field identifies metal fragments, triggering a reject device which diverts the metal out of the process and into a metal recycling area. The metal detector can identify fragments as small as 1.4mm in size.
Terry Ashton, Process Engineer at Viridor commented; “We have been delighted with the Eclipse Metal Detector. Whilst we have invested heavily in a highly efficient process at our Sheffield glass recycling facility, we are always striving for continuous improvements to maximise recyclate quality. The installation of the metal detector into our process has eradicated the issue of metal contamination in the final product, ensuring that Viridor’s customers receive a high-quality product which is as good as virgin glass”
