Novozymes to Supply Enzymes to DONG Energy’s REnescience Plant in UK : Ding DONG Deal for World First Full-Scale Enzyme Enabled Waste Treatment Plant
Danish biotech firm Novozymes has signed an agreement with DONG Energy to deliver enzymes for the REnescience plant in Northwich, UK - the first full-scale plant in the world to use enzymes to maximise material recycling and biogas generation from household waste.
DONG explained that with REnescience technology ordinary unsorted household waste is mixed with water and enzymes in a large reactor.
The chemical process then begins and the enzymes dissolve all food waste, labels and similar types of organic waste and turns it into a liquid that can be used for biogas. At the Northwich facility, the biogas will be used to generate around 5 MW of electricity.
The remaining part of the waste is said to be plastic and metals, which can be recycled, and the remainder converted into fuel.
Novozymes and DONG Energy have also agreed to further develop the enzymes for the technology together.
"The further development of the enzymes will help us to continuously optimize the process and, at the same time, extract even more valuable products from the waste,” commented Thomas Dalsgaard, executive vice president at DONG Energy.
“This is both good for the environment and useful in terms of reducing the costs of waste management,” he added.
The REnescience plant in Northwich is expected to be operational in early 2017. It is expected to sort 15 tonnes of waste per hour or 120,000 tonnes per year.
DONG Energy said that it will finance, build and operate the plant in the North West of England and will also look into the possibilities for building similar plants in other places around the world.
The enzyme supply agreement is a long-term non-exclusive agreement.
