For the bioenergy industry, Cellwood offers solutions for pre-treatment of organic waste – transforming it into a substrate. The organic material comes from the food and agricultural industries, or from household waste collected by municipalities. After pre-treatment, the substrate can be digested into biogas – which is converted into electricity or used as fuel for vehicles.

Our solution can take care of incoming waste that includes packaging material and other non-organic contaminants – such as plastics, metals, sand and glass. The reject is efficiently removed, resulting in the cleanest substrate on the market. Our concept is based on four different treatment steps: dissolving, screening, separation and disintegration. They can be combined into a full process or installed as stand-alone upgrades in existing plants.

• Advantages with the Cellwood pre-treatment concept:
• Municipal handling of organic household waste can be sorted into plastic bags, as our process removes the plastics efficiently.
• Supermarket waste including high amounts of packaging material is efficiently cleaned.
• Sand and glass is separated from the substrate and prevented from accumulating in tanks and digesters.
• A disintegrated material increases the gas potential.
• As the substrate from our process has a low reject content, the digestate fulfills law requirements for use as agricultural fertilizer.
