New uses fordiscarded resources.

Paper, metals, organic material and hard-to-recycle waste need different approaches. We aim to connect appropriate technologies with practical uses, developing projects that keep resources in circulation.

Match the approach to the material

Look beyond collection.

  1. Paper and metalsSeparationMaterials
  2. Suitable organic feedstockAnaerobic digestionGas
  3. Hard-to-recycle wasteEnergy recoveryPower & heat

Prevent waste first. Prioritise reuse and recycling, then assess suitable recovery options.

Four areas. A connected resource system.

Separate materials, recover energy, digest organic feedstock and connect recovered resources with their next use. These are proposed business approaches, not descriptions of operating company facilities.

Waste Management & Processing

Recovering value from municipal, commercial, industrial and organic waste.

We aim to develop practical infrastructure for collecting, separating and processing waste. Material recovery, recycling and the treatment of legacy waste can help turn discarded streams into useful resources and energy feedstocks.

Feedstocks and areas of focus

  • Municipal solid waste
  • Wet and dry waste
  • Organic waste
  • Legacy waste and biomining
  • Material recovery and recycling
  • Refuse-derived fuel (RDF)

What matters for a viable project

Sorting quality shapes what can be recovered. We consider material quality and the requirements of potential users.

Waste-to-Energy

Recovering energy from suitable waste that cannot be recycled.

Appropriate energy-recovery technologies can complement recycling. Our focus includes RDF-based recovery, biomass, biogas, syngas and thermal conversion, with technology choices assessed against the characteristics of each waste stream.

Feedstocks and areas of focus

  • RDF-based energy recovery
  • Biomass energy
  • Biogas and syngas
  • Thermal conversion
  • Power and heat recovery

What matters for a viable project

Where will the recovered heat or electricity be used? Reliable demand and operating conditions matter alongside the equipment.

Biomethanation & Bio-CNG

Converting biodegradable materials into renewable gas.

Anaerobic digestion uses microorganisms to produce biogas from suitable organic waste. Biogas can supply heat and electricity, or be upgraded and compressed into Bio-CNG. We consider feedstock availability, technology, fuel demand and the handling of digestate together when assessing a project.

Feedstocks and areas of focus

  • Municipal organic waste
  • Food and market waste
  • Agricultural residues
  • Industrial organic waste
  • Suitable biodegradable biomass

    Upgrading and compression to Bio-CNG

What matters for a viable project

Bio-CNG is fuel made by removing carbon dioxide and other impurities from biogas, increasing its methane content and compressing it. The required quality depends on its intended use.

Circular Economy

Keeping materials and resources in productive use for longer.

Our approach links recovery, reuse, recycling and regeneration. It considers how materials, energy and organic resources can be recovered together rather than treating each waste stream as a disposal problem.

Feedstocks and areas of focus

  • Materials → recycling
  • Organic waste → biogas
  • Biogas → Bio-CNG
  • Suitable residual waste → RDF / energy
  • Digestate → nutrient and organic resource recovery

What matters for a viable project

Keeping resources in use depends on quality and demand as well as quantity. We consider local use and wider regional cooperation where needed.
