Construction giants hail zero waste ‘game-changer’

Tarmac has joined forces with Morgan Sindall to develop trench recycling technology that claims to eliminate waste sent to landfill and cut reinstatement costs by almost a third.

The TrenchFSMR technology recycles utility trench arisings by creating a flowable structural material for reinstatement by using 100% of the material that comes from utility trench excavations.

Produced in accordance with the WRAP Quality Protocol, the system avoids utility arisings being sent to landfill, and cuts carbon by reusing materials and reducing the need to manufacture and transport reinstatement materials from off site.

With only two operatives required to produce it, Tarmac says the system streamlines the reinstatement process and significantly cuts labour costs compared to traditional utility trench reinstatement.

A three-month trial has demonstrated that the system can also eradicate compaction issues that often lead to reinstatement failure. By recycling and reusing materials, the technology can also be used to support CEEQUAL project accreditation.

Tarmac account manager Hannah Bettison who helped pioneer the technology said it was successfully trialled on utility works in Worcestershire undertaken by the West Midlands Gas Alliance a partnership between Morgan Sindall and National Grid.

“The system helped to support National Grid’s commitment to reducing volumes of utility trench arisings sent to landfill,” she said.

Tarmac national business development manager Geoff Fawkes added: “TrenchFSMR is the next step in providing contractors and utility clients with a quick, cost-effective recycling system that can immediately reprocess trench arisings to provide a material that can be used on the same site.”

Morgan Sindall said it was now using the technology in Nottingham before rolling it out across the Midlands.
