A Radical Rethink
of how we use landfill sites for good
Based on the concept of the ancient midden where waste would provide heat, material to burn and composted biomass, the Sustain Super-Midden is designed to turn landfill sites into energy, heat, food, and fertiliser generating centres for the benefit of the local community.
Sustain Wiltshire was founded by
Recycling & Landfill Centre

Super-Midden Project
Paving the way for
LOCAL FOOD & POWER PRODUCTION
Combined with heat extracted from the landfill site, and power from the on-site energy from waste plant, the positively pressured, inflatable growing domes will be kept at a perfect growing temperature for horticulture throughout the seasons. Read more >>
Through a series of wells placed within the landfill, gases from waste decomposition are collected and piped to a central location where it is cleaned and used to fuel a Combined Heat and Power Gas Engine. Read more >>
Using the landfill as a distribution hub, just-in-time food will be delivered daily, reducing food miles and removing the need for large storage and warehousing operations. This approach enables cheaper and more sustainable food. Read more >>
Leachate from landfill can be harvested and is high in phosphates which can be refined into fertiliser, providing a sustainable alternative. Read more >>
Huge CO2 savings

*Estimated kg of CO2 we could have saved since submitting our planning application in July 2024
Specifically designed to be biosecure and fully encapsulated, our flexible growing domes will be located on securely sealed landfill cells. Methane gas produced from within these cells will be used to produce sustainable energy and heat, helping to maintain the perfect growing temperature for horticulture throughout the seasons.

That means taking the good with the bad, and occasionally the downright ugly. Over a year on and nothing could be truer. Sadly, positive news on the planning front remains thin. So, instead I’ll share exciting news about the growing dome. The Good Despite the failure of […]

Shooting for the stars!
Late on 01 April – 10:35 GMT, to be precise, NASA’s Moon rocket Artemis II launched carrying astronauts to the Moon for the first time in almost 54 years, closely followed by the attention of the world’s media. Having orbited the Earth, its translunar injection burn ignited and the craft, carrying its crew of four, broke free from the Earth’s orbit on its 240,000-mile journey to the Moon. This was the third launch attempt by NASA since February. […]
