Hereford Quarries recycles 100% of inert waste with CDE wet processing plant
In 2015, Wye Valley Group, Herefordshire's leading trade waste recycling business, established Hereford Quarries Ltd. Based at its new 10-acre Lugg Bridge site north-east of Hereford, its aim is to maximise local resources to reduce the county’s reliance on imported virgin primary aggregates.
The operation began with a mobile jaw crusher and screener to process construction waste into basic crusher run and hardcore materials, suitable for use as low-grade sub-base material.
Hereford Quarries Commercial Manager, David Ambrose said, “The rudimentary crusher runs and hardcore products we started with allowed us to recycle inert construction waste
materials and subsequently helped us in meeting our sustainability objectives by processing material that was destined for landfill. However, the processed product was the minimum technical standard that could be accepted into the marketplace and, as such, would only command a price reflective of its quality.”
One year into its operation, Hereford Quarries partnered with CDE, the industry-leading wet processing equipment manufacturer, who was commissioned to provide a bespoke solution to recover quality-assured construction aggregates that complied with European specifications.
The objective of the CDE wet processing plant was to support Hereford Quarries in maximising the value of its feed material by producing washed and graded recycled sand and aggregates including drainage stone, MOT Type 1 and 65F.
David said, “The CDE wash plant is adding significant commercial and technical value to our operations. We are now recovering recycled aggregates back to their highest potential added value and to a technical and quality standard that can compete directly with primary aggregates.”
David went on to explain that the custom-built CDE wet processing plant can also process more challenging
material.
“We are able to process much higher volumes and more challenging materials with the CDE plant
compared to that which was possible with a mobile crusher and screen. The plant’s
high capacity provides the opportunity to up-scale our operations and
throughput as the market grows, whilst maintaining the high
product quality.
