Recycling contaminated planings using ULTIFOAM




Sheffield City Council wanted a sustainable solution to contaminated (tar bound road arisings) produced during highways maintenance. Contaminated material needed to be securely removed and transported for processing. We were able to offer the council our ULTIFOAM solution which is a closed-loop recycling technology allows up to 95 percent of all road arisings to be reused, including tar bound materials.

A mobile plant was established in a depot at Armthorpe Doncaster which is approximately 20 miles East of Sheffield. The plant equipment includes crushing, screening, bitumen and lime/cement storage and cold mixing plant. Contaminated materials produced by the replacement and maintenance of roads are sent to the site for investigation to determine material constituents. The road arisings are transported by registered waste carriers to the Armthorpe facility for recycling into products that meet the EA requirements in Regulatory Position Statement 075 and the Armthorpe facility can accept up to 2000 tonnes per day from the Sheffield contract.

By establishing the plant within one mile of the contract resulted in less traffic movements and lorries delivering planings to the plant also took a return load of ULTIFOAM to site. The laying operation had complete control of deliveries, even break times were coordinated between the site and mixing plant to ensure maximum efficiency. As the material is mixed cold overlaying the material can be carried out immediately after final compaction. In addition to its energy saving and recycling benefits ULTIFOAM is also an Environment Agency approved method for recycling tar-contaminated planings.
