Environmental

The environment was one of the main driving forces behind the idea to construct our MBT facility. We recognise that landfill is not a sustainable disposal method for waste, and that in a lot of cases, items once considered waste can be treated and turned into a resource.

Renewable energy is a growing sector around the world, with governments and businesses realising that using finite fossil fuels for power is not sustainable. Our MBT facility produces renewable energy from waste, utilising the methane (which is a greenhouse gas 25 times more potent than carbon dioxide) to produce heat and electricity.

Reusing nutrients is a concept linked with a circular economy i.e. an economy based on keeping resources in use for as long as possible. The food waste is broken down by bacteria during anaerobic digestion. A by-product of this is a compost-like output; a nutrient rich soil enhancer that recirculates the micro and macro nutrients back into the ground.”  

The building itself was developed with the environment in mind at every stage:

  • Rainwater is collected from the building and utilised in the process, reducing our fresh (mains water) usage.
  • Solar panels have been installed on our visitor centre, helping to reduce the amount of non-renewable energy consumed by the facility.
  • The building materials selected are recognised as having a low environmental impact over their life including extraction, processing, and manufacture and recycling.

Odour control is a very important part of the design and management of the MBT facility. Buildings are kept at a slightly lower pressure than outside to ensure fresh air enters when the doors are opened, rather than allowing odourous air to escape. We have three odour treatment stages to remove contamination from our emissions. The first one is a chemical scrubber that utilises chemical reactions to remove key parts of the odour; the next is a biological system that eats away all of the smelly material; and finally an active carbon bed to remove any remaining contamination.
