The Street Works Waste Classification (SWUK), launching in October 2025, is set to overhaul how waste from road and utility excavations is managed in the UK. For local authorities, contractors, and sustainability leaders, SWUK means clearer rules, digital records, and a powerful mandate to advance the circular economy in construction.
Every year, UK street works generate over 20 million tonnes of excavation waste. So, where does it all come from? The lion’s share is produced by utility companies during infrastructure upgrades, followed closely by local authorities and highways agencies.
It’s not just mud and rubble. This waste stream is a complex mix of:
Historically, most of this has been sent to landfill or used in low value backfill. SWUK is designed to change that by standardising classification and mandating digital tracking to encourage high-value reuse.
Construction, demolition, and excavation (CD&E) waste makes up a staggering 62% of all UK waste (DEFRA, 2022). Yet, a frustratingly small fraction of street works material is returned to high-value use.
SWUK’s digital-first approach makes it far easier to:
Of course, simply wanting to recycle more isn’t enough. Contractors on the ground face real challenges that often make landfill the default option. Here’s how Nexus ReGen helps solve them:
The Problem: The Clock is Ticking. On tight schedules, tipping waste at the nearest landfill is often the fastest choice.
