A big idea for energy efficient pyrolysis of 'waste' for regrowth circular bioeconomy

  • Microwave Assisted Pyrolysis (MAP): Transistor eg. GaN->Amplifier (@2.45 GHz) ->Tuned power output (with digital granularity) for the optimised dielectric loss tangent interaction->Machine Learning (ML) of unique feedstocks eg. Different categories of granulated plastic, dewatered sewage, solar/process heat dried biomass 'waste' residue, granulated car tyres etc. + co-generation of pyrolysis heat for Stirling engine eg.free piston-> (bio)electricity to self-power the electronics with a biochar/Carbon based supercap to start the process, excess bioelectricity for Redox flow eg.Fe/Redox Flow Desalination (RFD) battery storage + byproducts eg. Plastic monomers for virgin plastic and bio-oil for 'Ultra Low Sulfur Diesel (ULSD), Microalgae biochar (electrodes/electrolyte Carbon feedstock for supercaps, like the one used in this system) and more + Carbon Dioxide Removal (CDR) credits bought on a Carbon Removal Marketplace (CRM) platform

  • first pyrolysis unit optimisation: tuned for the 'Microalgae biorefinery' (see previous blog).
  • Most microalgae (e.g., Chlorella, Nannochloropsis, Scenedesmus) have cell walls composed mainly of polysaccharides (cellulose‑like β‑glucans, hemicelluloses, sulfated polysaccharides) and sometimes proteins and algaenan, but they lack the lignocellulosic triad of cellulose–hemicellulose–lignin that defines terrestrial biomass (https://www.intechopen.com/chapters/73244)
  • a VERY competitive space. Great work is been done in Canada for 'plastic waste'. Many great biochar kilns now commercially available around the Planet at all scales of feedstock 'waste' availability and feedstock characteristics which influence the kiln 'best fit' as well as co-generation requirements
  • I believe GaN transistors in GaN amplifiers could be the future for MAP - and energy efficient MAP the future of many 'waste to wealth' scenarios. How to access GaN MAP tech, pioneered by 'Scanship'?
  • alternatively, is there a 'better' transistor chemistry that is available via a commercial license - or even better - an 'open source' license?

  • failing that - 'flame cap' or 'TLUD' 'Appropriate Carbon Removal Technology' (ACRT) (see page on this site)
