  1. Northern Rivers & Tweed Valley •RIC •PROJECT 540 •B&B •SUGAR MILL GARDEN• WASTE FACILITY •

  2. “The Project 540 Kiln has the specific intent to sequester atmospheric CO2, in many small localities, and to make soil good to the seventh generation.” Geoff Moxham www.bodgershovel.com Constraints and goals • Accessible sensors • Validate simple visual tests • Cheap low-emission designs • Household uses of process heat Finessing efficient solutions including • Vortex flow induced in chimney stacks • Pre-heated and controlled air to tuyeres • Multiple purpose dampers & vents Building and testing prototype kilns • Catenary and sprung-arch trolley kilns • Side-loading carriages • Quenching and inoculating tanks Educational outreach • Community kiln-building projects • Market and show presentations Phoenix Kiln series • 20 L • 60L • 3 cu m, small farm

  3. Phoenix Rising • Human scaled for 1 person • Output must justify the input _________________________________________________ • Compact method producing usable amount of char. • Metal shell of washing machine makes smoke proof shell. • Lined with fire brick • Contains and store the heat • Worked well no need to top up fuel during burn Ben Speirs www.absorberroof.com Mark Feltrin www.gasificationaustralia.com

  4. Inside the kiln Simple parts Lifting the lid Double drum retort

  5. Future steps - Using the heat Creating independence • Heat for clothes drying • Hot water • Home heating • Refrigeration • Micro-gasification • Electricity generation Thermoelectric Organic Rankine Cycle Ben Speirs www.absorberroof.com Mark Feltrin www.gasificationaustralia.com

  6. Inoculating Biochar Charcoal pores: Tilling it in is “urban renewal, with quality public housing” If composted returns CO2 to atmosphere in 3-5 yrs. Biochar sequesters 30-40% of C for thousands of years. • Charring the weeds • Lantana vines • Camphor Laurel trees • Bamboo • Crush finely smaller than ¼ in, while wet • worms can transport the fines • Course meat grinder • Garbage disposal grinder, drip on inoculant • heavy drum roller • lawn mower over wet char in a bay • Inoculate with: • Urine, worm juice, compost percolation • Sea minerals, brewed crop specific teas • Biodynamic compost & soil • Application: 4t/ac = 2 lb/sy. Improves to 1lb/sf • Animals • Chickens, cows, ducks, pigs, pets, humans Hyphae: Microbial C reef

  8. Sugarcane Farming Tweed Valley - Robert Quirk Mulching with green cane tops returns C to soil rather than going up in smoke Nitrogen added, 2lb/ac facilitates break down of machine harvested trash Legumes planted directly into trash in fallow period Legumes add nitrogen Add lime at 2t/ac then scrapes top 8 inch into mounds giving equivalent 4t/ac of lime in the mounds Plant cane  into the  mounds improves aeration on land subject to flooding Traffic controlled to inter-rows & reduced cultivation minimizing soil damage, maximize soil life Lime & cultivate only once every 6 yrs 50kg N/ha 250kg K/ha 6kg P/ha

  9. Apply char at rate 2-4 ton/ac in 15 plots with some having no char Test for crop yield, leaching of nutrients, nitrogen cycling, emissions of CH4 & N2O Preliminary results indicate reduction in emissions of N2O with applications of 10t/ha green-waste biochar High sulphate soils No agronomic benefit found to char Trails continuing with reduced N High N20 with normal cultivation

  10. Biochar field site – Tweed Valley NSW Lab tests at DPI show up to 95% reduction in N20 emissions

  11. 30 MW cogeneration plant fueled by remnants from sugar production Saves 400,000 tons of greenhouse gases per year $220 million capital cost Future potential for biochar production. On farm collection of cane trash and use for biochar production requires proof of agronomic or climate benefit. There is interest in small scale production for return to fields as trials

  12. No green waste to landfills + fees: $80 /ton on weigh bridge $40 / ton Carbon Pollution Reduction Scheme Self hauled green waste = 6000 t/yr Bio solids = 2000 ton/yr Pickup green waste & kitchen = 4000t/yr Total = 12000 ton/yr Row compost for 6 to 8 weeks Sieve to separate: Fines for compost = 5000 t/yr Chips for mulch = 4000 t/yr Pyrolyze - biochar = 3000 t/yr Send back to community Residential gardens Community gardens Broad acre application on farms Small horticultural farms Macadamia, avocado, bananas Ballina Shire Population 40,000 Food Links Project: Build resilience against climate change & peak oil Waste Management Centre
