Skip Waste Valuable Material Recovery Success

Posted on: 8 August 2022

Northwest Recycling Ltd, Carlisle, recently invested in the ZAC800 material recovery system by waste separation specialists, Impact Air Systems.

The waste management company operates Brampton Skip Hire, the largest skip hire company in the North West region with over 2000 skips and a 16-acre recycling facility. The responsible disposal of waste and recovery of valuable materials from the waste stream is high on the agenda for Rick Allan, Northwest Recycling’s managing director and he appreciates the importance in investing in the right specialist equipment to assist in his efforts.

Material description: Glass
Particle size (mm): >40mm
Requested hourly throughput (t/h): 14 metric tons per hour
Mixed bulk density (kg/m3): 1000kgs/cubic meter
Heavy material description: Glass and ceramics
Light material description: Plastics, film and fibre

Mr Allan commented “We process around 75,000 tons of construction and demolition waste and using the ZAC800 we are able to process the sub 40mm fraction and very effectively achieve a mix of clean glass, stone and ceramic that can be used in our recycled aggregate facility. Investing in Impact’s ZAC800 was an easy decision for me, Impact carried out a detailed trial on our material and the results that were promised have now come to fruition. It has the ability to process waste streams at a high hourly throughput with material recovery results that are very impressive. The value in the cleaned glass and stone stream and Solid Recovered Fuel (SRF) stream will pay for the machine within the first 6 months of operation.”


Impact’s Zigzag Air Classifier (ZAC) has been designed to separate a vast range of applications, and is widely popular, not only for its impressive recovery results, but also for its durability and resistance to abrasive materials and less moving parts resulting in minimal downtime.

Nick Ball, managing director of Impact Air Systems said “The ZAC never fails to impress with its separation ability. We carry out material trials every week which mostly result in a sale. The fast ROI really is the icing on the cake and is the reason the ZAC can be found in a fast-growing number of waste facilities all over the world. We invite anyone to bring a sample of their material along and see the results for themselves!”
