Production and use of biochar
Production and use of biochar Montag, 25. März 13 Why we are interested in biochar ? • Terra Preta shows that biochar is very stable in soil • Soils with biochar a very fertile and do not need fertilizer any more • There are a lot of possibilities to develop different products from biochar Montag, 25. März 13 Experimental results of Sonnenerde (since 2008): • 10% biochar additive: Measurable benefits • C-and N-losses are reduced • By fermentation (Effective Microorganisms), no additional benefit • By combining 10% stone powder + 20% biochar: convergence of microbiology at TP • By reducing the pH - no benefits Montag, 25. März 13 All tests are carried out in practice adequate yardstick Montag, 25. März 13 To compare the microbiology a genetic fingerprint of each sample was created Terra Preta 20% biochar 10% biochar Without biochar Evaluation of taxonomic profiles of pseudomonads in composts, compared with an original Terra Preta Montag, 25. März 13 Construction and operation of a Pyreg-plant • because it can be produced a very high quality of biochar • because the emissions are very low • because the facility was one of the most developed one • Interesting scale, affordable Montag, 25. März 13 Feedstock paper fiber sludge grain husks green wastes Montag, 25. März 13 The new biochar-plant produce 1-1,5 tons biochar per day Montag, 25. März 13 In the dryingbox we use the excess energy of the pyrolysisprocess Montag, 25. März 13 The loading is large enough for the daily requirement of fuel Montag, 25. März 13 The charring is a pyreg reactor In the background is the exhaust heat exchanger Montag, 25. März 13 I am happy with my biochar Montag, 25. März 13 Experiences after one year of operation • Big step from prototype to continuous operation • 6500 hours per year are realistic (75%) • 300 to biochar per year • 150 kW heat output • Ash amount must be reduced Montag, 25. März 13 Duration of the Pyreg plant as a percentage of total hours 80 60 40 20 0 Montag, 25. März 13 Jän Feb März April Mai Juni Juli Aug Sep Okt Nov Dez Use of biochar: • Producing a high fertility Black soil • Developing a soil-activator • fixing Nitrogen (preparing manure) • feeding animals Montag, 25. März 13 Practical tests in raised beds Serie „E“ Montag, 25. März 13 Serie „G“ Practical tests with potatos in raised beds Montag, 25.

März 13 The aim of the soilactivator: • initiate a kind of Terra Preta effect (increasing carbon content itself) • stabilize a higher humus level • stabilize / increase harvest Montag, 25. März 13 How you get a soilactivator from biochar • Enrichment with nitrogen • Enrichment with Mo, Se, Co • Enrichment with humus-building microorg. • Enrichment with N-binding microorganisms Montag, 25. März 13 Addition of trace elements to develop a soil-activator Montag, 25. März 13 Mixing biochar, compost, nitrogen and trace elements with our oldest (and best) converting machine Montag, 25. März 13 Summary • Our biochar plant works continiously • We can produce different kinds of biochar • We try to develop different products from and with biochar • There is a big market for biochar products Montag, 25.
