Phase 1     Feedstock Management

The materials for conversion are sourced from both the commercial and residential sectors. A broad range of sources and collection methods can be supported.  Source separation offers the greatest probability of being able to produce high value, marketable products such as biogas and compost. 

Step 1:  Feedstock Receipt  

There are no specific ratios for waste sources that is required with the BTA® Process. Due to the inherent flexibility in the design, we are able to configure the plant to meet the biological profile of the incoming feedstock. The fluctuations and profile changes that will definitely be experienced when processing organic wastes are managed.


Source Separated Organics (SSO) Scenario : The generator has separated the materials and the reality is there will be inert contamination such as packaging, glass, plastics, metals and fine grit. It will be removed by loading the material directly to the BTA hydromechanical pre-treatment system, typically via a hopper filled using a loader.

Mixed Waste (MW) Scenario : A dry pre-treatment front end is designed using commercially available equipment that matches the inert profile for this feedstock. The use of trommel screens, and / or metals separators and /or sort stations (a MRF concept) can be used to capture recyclable resources and create a material (<80mm) that is then fed to the BTA hydromechanical pre-treatment system to remove the remaining fine contamination.

Rejects Fraction: Specific and obvious items not suitable for processing are segregated for collection and disposal or reuse.
