Fruit And Veg Self-Sufficiency Ahead Thanks To Heat From Sewage Farms

This headline caught my eye on an article in today’s Times.

This is the introductory paragraph.

Britain will become far more self-sufficient in tomatoes, cucumbers, peppers and other produce under plans to tap heat from sewage farms and pipe it to giant greenhouses.

The idea of using waste heat to grow fruit and vegetables is not new.

The technique is used at Drax power station and at various Scottish distilleries.

Low Carbon Farming just intend to do it with heat from sewage works.

  • They have identified 41 sites in the UK.
  • The greenhouses will be larger than the O2.
  • The first two sites are in East Anglia and are being built near two of Anglian Water’s sewage works.
  • Fully developed, they could make the UK self-sufficient in tomatoes, cucumbers and peppers and for most of the year.
  • It would be a £2.67 billion investment, that would create 8,000 jobs.

Intriguingly, if they need more heat, they’ll use a fossil-fuel combined heat and power unit. The carbon dioxide produced will be fed directly to the fruit and veg, as it makes them grow faster.

Another Source Of Heat

In Exciting Renewable Energy Project for Spennymoor, I wrote about a Durham University project to use the waste heat in old coal mines to heat housing.

Could this heat be used to grow fruit and veg?

  1. This sounds really a good, worthwhile project. Neil has an allotment, and grows most of our veg and some of our fruit organically. And items like tomatoes and strawberries I buy organic ones when he doesn’t have ready. I got some strawberries from my last Ocado shop and they were really delicious. But had come from Spain.
