1 Production and use of biochar

2 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

3 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

4 All tests are carried out in practice adequate yardstick

5 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

6 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

7 Feedstock paper fiber sludge grain husks green wastes

8 The new biochar-plant produce 1-1,5 tons biochar per day

9 In the dryingbox we use the excess energy of the pyrolysisprocess

10 The loading is large enough for the daily requirement of fuel

11 The charring is a pyreg reactor In the background is the exhaust heat exchanger

12 I am happy with my biochar

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

14 Duration of the Pyreg plant as a percentage of total hours Jän Feb März April Mai Juni Juli Aug Sep Okt Nov Dez

15 Use of biochar: Producing a high fertility Black soil Developing a soil-activator fixing Nitrogen (preparing manure) feeding animals

27 Plot trials with biochar-composts

28 Plot trials with biochar-composts

29 The aim of the soilactivator: initiate a kind of Terra Preta effect (increasing carbon content itself) stabilize a higher humus level stabilize / increase harvest

30 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

31 Addition of trace elements to develop a soil-activator

32 Mixing biochar, compost, nitrogen and trace elements with our oldest (and best) converting machine

33 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

34 Thanks for your attention
