RECYCLING & WASTE MANAGEMENT
WEEE WASTE PLASTIC AND SRF RECOVERY To assist with material decontamination of the waste electrical and electronic equipment (WEEE) material processed at Enva’s plastic recycling and recovery facility in Lincolnshire, UK. Enva employed the services of Impact Air Systems to provide a material separation solution that would remove contamination, improve current capacity, and enable operations to continue to grow. Enva recycles and recovers a large percentage of small domestic WEEE material generated annually in the UK. Its facilities around the UK and Ireland recycle and recover materials ranging from plastics, metals, wood, oil, glass aggregates for re-use in manufacturing and for energy conversion. Enva’s sink float system, used for the processing of plastics, was being compromised with heavy contamination from the material passing through it, so a density separation system was required to remove the light fibres, dust, and other residue from the rigid plastic material stream. The contaminated material was sent to Impact’s test facility for a trial run through the Zigzag Air Classifier (ZAC), a tried and tested solution, popular in the recycling and resource recovery industry for its effective ability to utilise air technology and density separation to clean valuable materials from contaminants. Impact’s test facility provided outstanding results, with the input material being cleaned to an exceptional level, which ultimately resulted in the sale of a ZAC800. For the plastic processing company, the ZAC800 handles up to 14 tonnes per hour at a bulk density of 350kg/m³, however as the ZAC is also available in a 1200mm wide version, compared to the 800mm, and is therefore capable of processing material at an even higher throughput.
