- Converting household waste to energy

What is Renescience and how does it benefit us?

If you think about how much the population is increasing and how much waste each of us produces, it´s clear we need new and innovative solutions for managing waste. Much of our rubbish could be recycled, in fact up to 84% of a typical average household

The answer is not to dump it in landfills or to burn it. The answer must be to use innovative technologies to recycle more of the waste we produce. To turn our waste into something we can re-use.
That is exactly what Renescience technology does.
Using enzymes, mechanical sorting, recycled water and anaerobic digestion, Renescience separates household waste into recyclables. Then it liquifies the organics from the waste and turns it into green energy.
Waste management has seen tremendous growth in recent years and EU policies are increasingly supportive of using alternative waste management technologies.

Recycles more

Using Renescience technology, there is no requirement for shredding, compared to source separation or incineration. This allows for a high capture rate of the biomass and recycling of materials. Furthermore, it complements dry source separation by households to push up recycling rates further.

Makes life easier

Renescience is a simpler and more efficient process than traditional waste management options. It makes our lives easier. It extracts as much of the useful waste as possible and deals with it in the most appropriate manner.

Saves money

The collection system for Renescience is simpler than those for organic source separation systems so cost savings can be achieved. Additionally, Biogas is often incentivised by government schemes enabling even higher margins or reductions of gate-fees when competing in waste tenders.

Creates jobs

Renescience Northwich, a world first full-scale bio plant, has employed up to 150 local people in its construction and will create approx. 25 full-time jobs once it's operational.

Creates valuable resources

Bioliquid used in the Renescience process is highly suitable for biogas production and a host of other chemical products. Metals and other high-grade plastics are also recycled

Reduces air pollution

Renescience reduces the need for incineration and therefore helps cut air pollution significantly. Under EU regulation, biomass is considered CO2-neutral.

The world’s first full scale Renescience plant was commissioned in 2020, and we are exploring further project.

Northwich Renescience plant

  • Treats up to 80,000 tons of waste per year equivalent to waste from approximately 70,000 UK homes.

  • 3 MW of baseload electricity generation

  • Creates clean recyclable material (plastic and metals), that can be used to make new plastic and metal based products

  • Clean inerts/gravel will be produced for use e.g. road construction

  • A by-product of the process – called digestate - can be used for land restoration (from mining).

  • The non-recyclable parts such as shoes, pieces of wood, textiles, foils with no recycling interest etc. will become fuel material for cement kilns and/or incineration plants elsewhere.

Renescience technology as a service 

Renescience can act as a” stand-alone” or” front-end” solution to various projects.

It can be used in combination with pre-sorting in households to achieve a much higher recycling rate, or it can be used instead of source sorting where more relevant.

Investment in technologies like Renescience help to achieve long-term profitable growth opportunities and value for communities.

Climate-friendly biomass

Our biomass is primarily wood pellets and wood chips derived from wood residues from sustainable forestry
