Food waste implementation at Sussex Community

Organisation: Sussex Community NHS Foundation Trust
Location: Arundel, Bognor, Crawley, Horsham and the Kleinwort Centre

Circular Economy

What's the idea?

It is estimated that roughly one in every six meals are wasted in the healthcare sector, which is a global environmental issue.

When food waste ends up in landfill, it releases methane gas as it breaks down and decomposes. Methane is 25 times more harmful than carbon dioxide when it comes to climate change.

Since 1st April 2024 all bedded units within SCFT now segregate food waste into its own waste stream for collection. This is processed via anaerobic digestion to stop it from entering land fill.

Food taken for anaerobic digestion:

 

  • Is placed in a sealed container for 30 days with no oxygen. As bacteria is produced it breaks down the waste, turning it into biogas, which is a cleaner gas.

 

  • Biogas is a renewable energy source that can generate electricity and heat for the waste plant and surrounding community.

 

  • Any leftover material is then used as farm fertilizer.

 

SCFT will next explore the introduction of food waste into the larger non-bedded sites

Impact of the project

Reducing waste

The anaerobic digestion process is considered recycling, thus reducing waste

Reducing pollution from methane

The segregation of food waste from general waste reduces any methane pollution created and helps tackle climate change.
