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 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 Ben Speirs Mark Feltrin 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

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

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

6 Inoculating Biochar 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 If composted returns CO 2 to atmosphere in 3-5 yrs. Biochar sequesters 30-40% of C for thousands of years. Charcoal pores: Tilling it in is “urban renewal, with quality public housing”

7 Compost Recycling BIOCHAR Site Bush regeneration Events Fund raising Food For All Seed savers Nursery Chooks Sustainability Alternate tech Research Workshops Education Promotions Children Mullumbimbi Community Garden “Growing to Share & Sharing to Grow” Design Compost loo Cob oven & BBQ area

8 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 Sugarcane Farming Tweed Valley - Robert Quirk 50kg N/ha 250kg K/ha 6kg P/ha


10 Ap ply 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 CH 4 & N 2 O High sulphate soils High N 2 0 with normal cultivation Preliminary results indicate reduction in emissions of N 2 O with applications of 10t/ha green-waste biochar No agronomic benefit found to char Trails continuing with reduced N

11 Biochar field site – Tweed Valley NSW Lab tests at DPI show up to 95% reduction in N 2 0 emissions

12 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

13 Ballina Shire Population 40,000 Waste Management Centre No green waste to landfills + fees: $80 /ton on weigh bridge $40 / ton C arbon P ollution R eduction S cheme 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 Food Links Project: Build resilience against climate change & peak oil

14 Thank you From the Project 540 Team
