Forty hectares of greenhouses, heated by the burning of rubbish, are acceptable to beryllium built successful Essex - making it the largest low-carbon horticulture tract successful Europe.
These greenhouses volition beryllium the archetypal of their benignant and could supply astir 6% of the tomatoes consumed successful the UK.
It should statesman operating successful 2027, erstwhile astir each the county's household rubbish volition travel to the Rivenhall site, wherever it volition past beryllium burnt successful an incinerator.
Gareth Jones works for discarded institution Indaver, which is gathering the facility.
He said: "The boiler produces steam and immoderate of that steam we'll divert to our caller vigor exchange, and that volition nutrient the blistery h2o that we'll beryllium sending implicit to our greenhouses.
"The remainder of the steam goes to the turbine, truthful it produces energy from the substation, and immoderate of the energy volition spell straight to the greenhouses."
Currently, Essex's household discarded goes to landfill wherever it gives disconnected greenhouse gasses, peculiarly methane.
Indaver claims that the CO2 emitted astatine the Rivenhall tract is 20% little than if the rubbish had gone to landfill, and determination are further biology benefits.
According to Defra, astir fractional of the UK's caller vegetables are imported.
Tomatoes often travel from Morocco, Spain and the Netherlands. But determination is increasing interest astir the immense fig of integrative polytunnels successful the southbound of Spain.
Almeria's 'Sea of Greenhouses' are adjacent disposable from space, and determination are regular droughts successful the area.
Trucks past bring the nutrient each the mode to the UK, releasing thousands of tonnes of CO2 en route.
Rivenhall Greenhouse task manager Ed Moorhouse says the UK's reliance connected importing effect and veg is not sustainable.
"Water porosity successful northbound Africa and successful confederate Spain is simply a cardinal issue, extremes of somesthesia and the effects of clime change," helium said.
"What we're seeking to bash is, if it was tomatoes, to reshore 6-8% of herb imports by increasing successful Essex."

Consequently, companies whitethorn person to bargain other onshore to offset biodiversity impacts, which would impact akin investments crossed the country.
A Defra spokesperson said: "We are moving intimately with the assemblage to marque Biodiversity Net Gain enactment much effectively, whilst investing £5 cardinal into farming, the largest ever fund for sustainable nutrient accumulation to bolster our nutrient security."
