RaCBio concept and how can it work

  1. 1. September 2020 Presented Horst Unterlechner 1
  2. 2. Renewable energy why? • Direction world is moving • Decentralisation of supply system • Electricity storage developments • Carbon tax & global pressure to reduce GHG • Anti-coal lobby • Utility challenges & escalating cost • Growing customer demand • Alternative fuel options • Self reliance & independence • Waste challenge 2
  3. 3. Biomass or Waste to Energy • Waste and sewage management growing challenge • Becoming an environmental treat • Large volumes biomass available - opportunity • Technology makes it possible to compete with grid power • Biogas – green solution to produce : • Domestic fuels – cooking & refrigeration • Renewable biofuels - green transportation fuel • Decentralised own generation – tri generation • IBERT has been involved in bio waste to energy technology solutions for past 10 year 3
  4. 4. iBert Largest biogas company in SA Build 7 tradition AD plants to date in SA +- 160 Europe piggeries, dairies, Napier grass, abattoir waste, food waste sewerage plant 7 year biogas & 30 years renewable energy experience Solutions for: • Commercial plants – ibert 20 to 350kW - SA 🇦🇹 🇿🇦 • Industrial (RaCBio ) – rapid cellulose bioreactor (second generation technology) 30 - 1,2MW 🇿🇦 • LVS Botswana - electrical & control specialist + MV & HV interconnection 🇧🇼 • KTS - Gas storage & cleaning technology for sewage gas 🇩🇪 • RuSiTec - Biological partner for RaCBio technology 🇩🇪 Partners : iRCB+LVS+KTS+RuSiTec4

  13. 13. Second Generation Bio-chemistry Nature has the answers J.W. Czerkawski •Copy natures process and convert all cellulose and hemicellulose material into biogas •Split traditional biogas process •Reduce retention time & plant size •Large selection feedstock •Much more controllable biological process Output •Protein rich substrate •Sulphurs free biogas •Nutrients rich water 13
  14. 14. Containerised modular plant • Retention time reduce to 72 hrs compared with 21 – 55 days via traditional AD • Modular design can process from 500kg up to 22 ton per day • Produce between 13 to 350m3 biogas per hour can be used as: • domestic fuel, transportation fuel or electricity generation • 500m3 of biogas for each ton of celluloses and or hemi-celluloses feedstock • Produce sulphur free biogas • By-product from system is: • proteins extracted from the feedstock and can be pelletised separately as animal feed • nutrient rich 100% organic liquid fertilizer containing phosphor, potassium, calcium and magnesium 14
  15. 15. RaCBio OUTPUT per ton of feedstock Input Output 1 000 kg cellulose feedstock DM>60% (maize, corm, wheat grass silage, etc) · +- 500 kg protein rich animal feed pellets with 15 – 40% pure protein per volume · 500m3 biogas; 52% CH4 = 22MJ/m3 energy from this it is possible to produce: · 1 700 kWh - electricity (at 35% conversion efficiency) or · 240 litres equivalent of diesel or petrol ( at 36Mj/litre) or · 180kg of equivalent LPG gas (at 49Mj/kg) · 500 litre of nutrient water (+- 80% of total volume) containing phosphor, potassium, calcium and magnesium this can be used as is or filtered into drink water · GHG saved 5,27 ton CO2e 15
