When most people think of landfill, they picture overflowing sites and missed recycling opportunities. But at Flame UK, we believe even the most challenging waste can have a purpose. While our top priority is always to reduce, reuse, and recycle, some non-recyclable materials can be repurposed in a positive, sustainable way—such as being used as landfill cover.

In this blog, we explore how landfill cover works, what materials can be used, and why it plays an important role in environmentally responsible waste management.

What Is Landfill Cover?

Landfill cover is a protective layer placed over waste at the end of each working day to:

Prevent odours escaping
Deter pests and vermin
Minimise wind-blown litter
Reduce the risk of fires
Control moisture and greenhouse gas emissions

Under UK regulations and environmental permits, daily and intermediate landfill cover is a legal requirement. Traditionally, this involved using virgin soil or aggregate. However, waste-derived materials are increasingly being used instead—supporting a more sustainable and resource-efficient approach.u.

Why Waste-Derived Landfill Cover Is a Greener Choice

Using low-value, non-recyclable waste as landfill cover helps to:

✅ Conserve Natural Resources

By substituting soil or quarried aggregate with approved waste materials, we reduce the need to extract and transport virgin materials—cutting carbon emissions in the process.

✅ Improve Site Safety and Environmental Compliance

Effective landfill cover helps maintain operational safety and environmental compliance by controlling dust, odours, and gases. It also enhances site stability and supports engineered containment systems.

✅ Support Circular Economy Goals Repurposing waste as landfill cover aligns with the waste hierarchy by ensuring all materials are reviewed for recycling and recovery first. Only residual, non-recyclable materials are considered for cover use—ensuring nothing valuable is lost unnecessarily.

What Waste Materials Can Be Used for Landfill Cover?

Waste materials must meet strict criteria before they can be approved for use as landfill cover. Permitted materials may include:

Non-hazardous fines (from mechanical waste treatment)
Low-grade construction and demolition waste
Processed residuals from materials recovery facilities

Each material must be assessed for environmental safety and approved under site-specific landfill permits and Environment Agency guidance.

A Circular Approach to the End of the Line

At Flame UK, we see waste differently. We don’t just collect and dispose—we assess, recover, and repurpose wherever possible. Using low-value, non-recyclable materials as landfill cover is just one way we’re helping businesses close the loop on waste, supporting compliance and sustainability at every stage.

It’s not landfill as usual. It’s landfill with intent.
