Project background

Avon Material Supplies (AMS) recently supported an innovative renewable energy project in collaboration with ECO Sustainable Solutions. The development involved the construction of circular concrete bases and a surrounding catchment area to house new food waste digester tanks at ECO’s site in Parley, Dorset.

The digester tanks form part of ECO’s wider commitment to generating sustainable energy from food waste, an environmentally focused process that converts organic waste into biogas through anaerobic digestion. The project required high-specification, watertight concrete solutions to ensure the long-term integrity and environmental safety of the system.

AMS involvement

AMS was contracted to supply all concrete for the various stages of the build, including:

  • Watertight concrete for the digester tank bases
  • Standard concrete for the ground slabs
  • Concrete for the surrounding spillage catchment walls

Materials and volumes

To date, AMS has delivered 820 cubic metres (m³) of concrete to the site. The watertight mix, in particular, required close attention to detail to ensure compliance with project requirements and environmental regulations.

Overcoming challenges

A key technical challenge was maintaining consistent quality and performance of the watertight concrete. To achieve this, the AMS team worked in close coordination with the watertight chemical supplier, ensuring the correct formulation was maintained throughout the supply period.

This collaborative approach was crucial in meeting the project’s tight specifications and ensuring long-term durability of the digester bases.

Feedback

AMS received positive feedback from Mildren Construction, the main contractor overseeing the build. They were impressed with both the reliability of the service and the quality of the concrete supplied.

Further feedback may be added from ECO Sustainable Solutions in due course.

“We’re proud to be involved in this project, supporting another local business in a forward-thinking, environmentally positive initiative. It’s a fantastic example of how the construction and waste sectors can work together to create sustainable energy solutions.”
