This project was initiated in 2006 to identify ways that excavated
ground works material, resulting from jointing, maintenance and new
construction could be recycled. With increasing pressures on landfill
use, the project investigated and implemented changes in the
management and reuse of excavated materials by UKPN to reduce tonnage of material sent to landfill each year.
A second phase of the project concentrated on sustainable working
practices. By taking a holistic view of streetworks activities Phase 2
delivered a tool that determines the most sustainable approach to the
Phase 1 of this project demonstrated that excavated materials could
be recycled at one of several recycling facilities in the UK to meet
Highways Authority requirements. The recycled materials can be
classed as replacement type 1 material and can be used to backfill
The Carbon Calculator developed in Phase 2 delivered a tool based
on the PAS 2050 standard and it can be used to take a holistic view
of planned work. The tool aims to determine the most sustainable
method of work on a job by job basis, and has the aims of
implementing sustainable working and overall reduction in
greenhouse gas emissions.
