ZeroWastePilot

Biowaste2Gas develops their gasifier technology for use in the circular bio-economics of the future by optimizing the possibilities for utilizing both the energy content and the fertilizer value of 2 products in the residual segment – sludge from wastewater plants and the used fiber fraction from biogas plants. The gasifier process is a 3 step process:

1. The gasifiers pyrolysis section gasifies a number of xenophobic pollutions – microplast, certain heavy metals and pesticide together with the volatile components from the infeed

2. After the gentle gasification of the volatile components, the gas production is optimized by a water-gas-shift of the biochar

3. The gasifier gas is quickly heated to 900-1100 degC to break the tar otherwise present

During this project a 100 kWgas pilot gasifier is build based on the ground breaking work of Dan Christiansens (CTO in Biowaste2Gas) gasifier design, the pilot system is submitted to a number of lifetime tests and is fed with used fiber fraction with different pre-treatments. In parallel, experiments are conducted by AU to document the possibilities for bacterial upgrade of the gas to biomethane (or Renewable Natural Gas - RNG). A number or work packages analyses and document the business potential in deploying the gasifier within wastewater treatment plants and biogas systems.
