How Energy-from-Waste reduces landfill and supports the UK's circular economy transition

With 16.8 million tonnes of residual household waste produced each year, the UK faces a significant and growing infrastructure challenge in how it manages waste that cannot be recycled.

At the same time, the policy environment is also evolving. With recycling reforms, rising cost pressures and stronger environmental targets, the question is no longer whether change is needed, but how residual waste can be managed in a way that supports both sustainability and energy resilience. This is where Energy-from-Waste plays a critical role.

At Encyclis, we recognise the opportunity for the sector and we are helping to drive this transition by converting non-recyclable waste into electricity, heat, and reusable materials, keeping it within a productive system and out of landfill. As a leading Energy-from-Waste business, we provide a consistent, compliant solution that manages residual waste at scale while supporting the UK’s transition towards a more circular economy.

Moving to modern residual waste management

Landfill is no longer just environmentally undesirable, it’s becoming fundamentally unworkable.

What was once the system’s default option for residual waste management is now being squeezed from every angle: policy, cost and public tolerance.

Over the last 20 years, the share of waste going to landfill has fallen steadily and the latest increase in landfill tax this April has reinforced the government’s intent to continue push waste further up the hierarchy. At the same time, capacity constraints are no longer a distant concern. With fewer active sites and tighter controls, the idea of landfill as a reliable fallback is quickly eroding.

But these pressures don’t just disappear, they resurface elsewhere. We’re seeing that play out in the rise of illegal dumping and unlicensed waste activity. Enforcement activity is increasing with DEFRA having recently published a new Waste Crime Action plan backed with greater enforcement powers, a dedicated intelligence unit and additional £45 million for the Environment Agency spend on waste crime enforcement. However high-profile incidents like that of Kidlington, Oxfordshire continue to showcase the scale of environmental damage and community disruption these sites can cause, underlining that while government is taking this issue seriously, there is also a clear role for industry in supporting compliant, long-term waste solutions.

Overall, the policy direction is clear: a decisive move away from landfill. The challenge now is to ensure that this shift is matched by the development and support of reliable alternatives, capable of managing residual waste responsibly while advancing broader circular economy ambitions.

The Circular Economy aims to maximise the utility of existing resources

How Energy from Waste Supports the Circular Economy Transition

Even with ambitious recycling targets, residual waste remains unavoidable. Complex packaging, contaminated materials, and non-recyclable products cannot yet be eliminated entirely.

As one of the UK’s leading Energy from Waste operators, Encyclis ensures this material is managed responsibly and productively, contributing to society rather than creating long term environmental liabilities.

Through our network of state-of-the-art energy recovery facilities, we transform residual waste into:

  • Electricity, helping power homes and businesses while providing reliable baseload energy to the grid
  • Heat, supporting local, low-carbon energy networks and reducing reliance on gas
  • Recovered metals, including aluminium and steel, returned to manufacturing supply chains
  • Construction materials, with around a fifth of the waste we process becoming aggregate used in roads and infrastructure

Materials that would otherwise sit in landfill for decades are instead converted into energy within hours, with the remaining outputs recovered and reused.

Increasing energy security and recovering resources

The impact of Energy-from-Waste is visible in people’s everyday lives.

Across our operations, we divert over 1.8 million tonnes of waste from landfill each year. To put that into context, that’s the equivalent to more than 1,000 Olympic-sized swimming pools of waste that would otherwise be buried in the ground.

At the same time, we generate enough electricity to power hundreds of thousands of homes, providing stable, local energy that supports both the UK’s energy security and its transition to a lower-carbon system. Across the UK as a whole, energy recovery now produces over 10,000 GWh of electricity annually, enough for around 3 million homes.

There is also a significant materials story. The UK recovers over 40,000 tonnes of aluminium each year from energy recovery processes, while around 2 million tonnes of aggregate are produced annually from bottom ash. These materials would otherwise be lost. Instead, they are returned to use in construction, manufacturing, and infrastructure, extending their value well beyond their original lifecycle.

The value of Energy from Waste

The UK will continue to produce residual waste. The real question is what we choose to do with it. Energy-from-Waste has a vital role in residual waste management.

At Encyclis, we focus on making sure that residual waste delivers value, not liability. By turning it into energy and reusable materials, we help keep it within a controlled, productive system and out of landfill or illegal routes.
