Through the production of fruit and vegetables at a lower cost than the supermarkets, Sustain also has a part to play in both alleviating food shortages and addressing the cost-of-living crisis, while also providing affordable heat and power to make this possible.
Each year, the current landfill site at Brinkworth Road in Royal Wootton Bassett, produces up to 2.6 million cubic meters of methane gas.
This is burnt off using a flare system to prevent a build-up of gas within the commercial and industrial waste landfill cells. This is the equivalent to 3,800 tonnes of CO2 being released into the atmosphere each year.
By using this gas to power engines and generate electricity, CO2 that is produced can be fed into the inflatable growing domes.
A lagoon and reed bed will be added to enhance wildlife. This will be used to balance runoff.
Water capture will also be used in the growing domes, and artificial wetlands will be utilised to both store water and enhance biodiversity.
An extensive bund will be added around the site to shield it from Wootton Bassett, the motorway and the railway. This will be planted with native varieties of trees which will link the existing woodland to form a green corridor of indigenous woodland, further enhancing biodiversity on site.
Leachate from landfill can be harvested. This is high in phosphates and can be refined into fertiliser, providing a sustainable fertiliser alternative.
Spare energy from the methane gas engines, alongside electricity generated by the energy from waste plant, will be provided to support green industrial development and recycling.
