Severn Trent Green Power purchased Agrivert's operating facilities in 2018, and thus significantly increased our network of facilities. We are now the largest combined food waste recycler and composting businesses in the UK.
We have recently opened our latest AD facility in Derby and we are thrilled to see our other 7 AD facilities recycling record levels of food waste and producing renewable energy in equal measure.
Our growth and success has been exponential over our 22 year lifespan. This is largely thanks to our customer-focused and technically competent team, our forward thinking attitude and tailored approach to all endeavours.
