IN Brief:
- MPA UK Concrete has published a circular economy action plan covering concrete’s full design, construction, use, and recovery lifecycle.
- Manufacturing waste sent to landfill had fallen to 0.3kg per tonne by 2023, with zero waste targeted by 2030.
- The plan expands measurement into packaging, surplus concrete, take-back schemes, design for adaptability, and higher-value recovery.
MPA UK Concrete has launched a sector-wide circular economy action plan intended to keep concrete, its constituent materials, and associated packaging at their highest practical value throughout construction, use, demolition, recovery, and reuse.
The plan brings together manufacturers, designers, developers, contractors, demolition specialists, regulators, and policymakers around a common set of actions and measurements. Rather than concentrating only on factory waste, it extends circularity across the full building lifecycle, from material specification and structural design to deconstruction and the treatment of recovered concrete.
Concrete manufacturing waste sent to landfill had fallen to 0.3kg per tonne by 2023, according to the sector body, which is targeting zero manufacturing waste to landfill by 2030. Waste-derived materials also supplied 54.1% of the fuel used by the domestic cement sector in 2023.
Those improvements provide the starting point for a broader programme covering recyclable packaging, producer take-back schemes, reduction of surplus ready-mixed concrete, better collection of site waste, and stronger markets for recovered products. The plan also seeks more consistent data so progress can be measured beyond individual projects or manufacturers.
Design decisions sit near the centre of the strategy because the useful life of concrete is often determined long before demolition begins. Adaptable structural grids, accessible connections, accurate material records, and realistic allowances for future change can keep frames and components in service when a building is refurbished or repurposed.
Where retention is not possible, the plan favours deconstruction and higher-value recovery over indiscriminate demolition. Reclaimed elements can potentially be reused, while processed concrete can supply aggregates or other materials, provided quality, certification, logistics, and demand are established early enough to support commercial use.
The action plan builds on resource-efficiency programmes pursued by the sector since 2014, but its wider scope reflects growing pressure to address embodied carbon and material consumption alongside operational energy. Concrete remains fundamental to housing, commercial buildings, transport, water, energy, and public infrastructure, so relatively small improvements across high volumes can produce substantial aggregate gains.
Achieving those gains will require procurement models that reward retained value rather than simply paying for removal. Demolition contractors frequently work within short programmes and constrained sites, while reused materials need surveys, testing, storage, handling, and a confirmed destination. Without those conditions, crushing material for lower-value applications remains the fastest and least risky route.
Accurate building information can reduce that uncertainty. Material passports, verified product data, and digital records of reinforcement, strength, exposure, and previous alterations can help future teams assess whether a structure or component is suitable for retention. Much of the existing building stock lacks that information, leaving intrusive surveys and conservative assumptions to fill the gap.
New projects offer a clearer opportunity to create those records from the outset. Designers can also simplify future separation by avoiding unnecessary composite assemblies, inaccessible fixings, and connections that make components impossible to remove without damage, although those choices must still satisfy structural, fire, acoustic, durability, and cost requirements.
Material innovation is developing in parallel with circular design. The use of calcined-clay concrete at Brent Cross Town has shown how lower-clinker mixes can move from trials into live structural applications, while other projects are testing recovered aggregates, alternative binders, and carbon-cured products.
Circularity and carbon reduction are related but not interchangeable. A product containing recycled material may still carry high processing or transport emissions, while retaining an existing concrete frame can avoid far more embodied carbon than substituting a small proportion of aggregate in a replacement structure. Project teams will need whole-life assessments that compare credible options rather than relying on a single recycled-content figure.
Standards and liability remain significant constraints. Structural products require dependable performance, and engineers, insurers, warranty providers, and building-control bodies need evidence that reused or recovered materials meet the required specification. Developing accepted testing and certification routes will be essential if circular products are to progress beyond isolated demonstration schemes.
Local supply chains will also shape what can be achieved. Heavy materials lose environmental and commercial value when transported over long distances, so reuse works best where demolition, processing, storage, and new demand can be coordinated within the same region. Urban regeneration programmes and long-term infrastructure pipelines provide opportunities to plan those flows across several projects rather than treating each site separately.
Ready-mixed concrete presents a different challenge because production is closely tied to daily site demand and material cannot be held indefinitely. Better ordering, real-time communication, pour planning, and take-back arrangements can reduce surplus, but the greatest savings depend on programme certainty and accurate volume forecasting across contractors, suppliers, and placing teams.
Packaging, pallets, protective materials, and delivery systems form a smaller part of concrete’s overall footprint, yet they offer practical improvements that can be introduced quickly. Reusable systems and producer collection schemes are easier to scale where specifications are standardised and return logistics are built into supply agreements.
Public procurement could accelerate adoption by setting measurable requirements for retention, design for adaptability, material recovery, and verified secondary content. Those requirements must remain proportionate, however, because poorly defined targets can encourage superficial compliance while adding documentation that does little to change design or site practice.
The sector’s action plan establishes a common direction, but delivery will depend on decisions made in briefs, designs, contracts, logistics plans, and demolition strategies. Reducing factory waste has already removed much of the easiest material loss; the next stage requires clients and project teams to preserve value across organisational boundaries and over the much longer life of the built asset.
