Bioenergy
Reject removal from organic substrate Pre-treatment of household waste with efficient removal of plastics and grit.
Our solution
For the bioenergy industry, Cellwood offers solutions for pre-treatment of organic waste – transforming it into a slurry. 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.
HC-pulper
Dissolving of the waste is made in a pulper. This is the first step in Cellwood’s system concept for pre-treatment of organic waste.

Reject separator
Screening of the substrate is made in a reject separator. This step removes plastics and metals, and can be implemented together with a pulper or with a wet hammer mill.

High density cleaner
Removal of grit is made in a high density cleaner. This step separates particles such as sand and glass from the substrate, and prevents sedimentation in digesters and tanks.

Deflaker
Disintegration is made in a deflaker. The grinding of the organic material enables more gas potential, resulting in an increased biogas yield.
