What happens to construction and demolition waste?

When buildings, extensions or structures are destroyed, a huge amount of waste is left behind. Concrete, hardcore, wood, metal and plasterboard are just some of the materials that homeowners and project managers alike have to dispose of.

In the UK, construction and demolition waste makes up over half of all waste produced, and it’s becoming an issue that affects us all.

At SRC Group, we look at waste differently, in fact we see it as a valuable resource than can be given a new lease of life. So, what exactly happens to construction and demolition waste? Here’s how SRC deals with it:

Muck away and demolition waste collection

Once excavation or demolition begins, SRC Group can step in to offer muck away services. This involves removing inert material like soil, hardcore or rock as well as non-inert waste, like contaminated soil. Our team makes sure that waste is dealt with responsibly from the start. With the biggest fleet of tipper and grab lorries in the South East, SRC makes quick work of even large-scale projects.

We also ensure that the waste is classified before removal, with our rapid in-house soil testing. Thorough testing will clarify whether hydrocarbons, heavy metals, or asbestos is present in the waste. Harmful waste can then be identified and handled correctly, ensuring that you avoid any potential health or environmental issues.

Demolition waste and material recovery

At SRC we don’t just take away rubble, we offer full a full range of demolition and material recovery services. This means that all materials suitable for processing and crushing on-site are then available to reuse straight away. Anything leftover that cannot be processed is brought directly to our own on-site recycling centres.

Owning this process end-to-end is a huge part of our circular economy, which ensures that waste is processed properly, and reused wherever possible.

Recycle

We crush, screen, wash and test all waste that we process before turning these materials into:

  • Aggregates: Our high-quality aggregates can be used in a huge range of construction projects. These are also delivered via our extensive fleet of GPS-tracked vehicles, ensuring that you stay on track throughout the project. Our flexibility makes us one of the leading aggregates suppliers in the country.
  • ECO‑BLOC® blocks: Concrete blocks made with recycled fine and coarse aggregate plus cement. They can be used for cavity and load-bearing walls, block and beam floors, as well as below ground applications.
  • Low-carbon ready mixed concrete: Offering five mixes, including cement-free options; our mixes help to reduce CO₂ without compromising performance. In addition, four of which are suitable for use in all ST and GEN mix applications and are compliant with BS8500-2 and NHBC specs.

Reuse with SRC Build

Here’s where the full circular economy magic happens; SRC Build. SRC Group’s construction arm uses these recycled products in hundreds of projects on a daily basis. Demolition debris becomes aggregates which becomes blocks and concrete; forming the very base of new buildings and structures. No landfill shortcuts, no lost value, just an efficient and environmentally-friendly closed-loop system.

Land restoration

Sometimes the leftover materials can’t be used to create new buildings via recycling, however, at SRC we never throw anything out carelessly. Instead, we use this final-fill in restoration projects, bringing new life to old quarries and damaged land.

This regenerates biodiversity and creates new agricultural spaces. In 2024, our first year of reinvigorating unused spaces, we turned 20 acres of old quarry into arable land, using materials that would otherwise have been wasted.

Recycling hazardous waste

Some demolition projects involve asbestos, solvents, pesticides, or contaminated soil. SRC’s team is fully licensed to handle hazardous and non-hazardous muck-away. We offer onsite treatment and bespoke disposal planning, meaning even complex waste streams are handled safely and legally.

Domestic and small-scale demolition

It’s not just large construction firms that generate waste; small demolition jobs like extensions, garage removals, or shed clearances also produce huge volumes of bricks, timber, concrete and soil that need to go somewhere.

At SRC Group, we work with local builders and homeowners to collect and process construction and demolition waste on domestic projects. Whether it’s a single load from a driveway renovation or multiple skips for a home extension; our team ensures that material is collected efficiently and put back into the circular economy.

We apply the same WRAP-compliant recycling processes to domestic waste as we do for commercial sites, meaning nothing gets overlooked, and your project stays compliant with environmental guidelines.

For example:

  • Concrete and brick rubble is crushed and reused as sub-base in new builds or roads.
  • Timber is separated and either recycled or sent for biomass energy recovery.
  • Spoil from garden or groundworks can be cleaned and reused in land restoration.

Even on the smaller end of the scale, the principles of the circular economy hold true: reuse what you can, reduce what you waste, and make sure as little as possible goes to landfill.

Whether you’re a homeowner doing a renovation or a small contractor managing multiple jobs, SRC offers:

  • Flexible collection services
  • Clear documentation and waste transfer notes
  • Access to high-quality recycled aggregates for your next job

The benefits

Environmental gains

SRC has diverted 30 million tonnes of construction and demolition waste from landfill; cutting pollution, preserving raw materials, and reducing greenhouse gas emissions. Using recycled materials helps our clients to meet sustainability benchmarks like BREEAM or ESOS, which are particularly important for public-sector or green-certified bids.

Cost efficiency

Recycling on-site and using locally sourced recycled aggregates can reduce transport and disposal costs. Plus, avoiding landfill fees and the Aggregates Levy can add to the cost savings.
