Erbil, Janin, Rebecca and Giorgos
BISC-E Challenge 2018
Innovation
Azolla, a novel sustainable crop which can be grown
independent of Haber-Bosch fertilizer
PhD Thesis Paul Brouwer, 2017
Haber-Bosch Reaction
Erisman et al., 2018
Global Problems
• 80% of nitrogen in our body is Haber-Bosch nitrogen
• 2% of the world’s total energy production
• Environmental problems and threat to water life biodiversity
Dreschel, 2017
Bio-Utilization of Symbiont
Nostoc azollae fixes atmospheric nitrogen into organic nitrogen
Azolla pinnata
600 – 1000 kg nitrogen ha-1 y-1
Glycine max
60 – 200 kg nitrogen ha-1 y-1
Hamdi, 1982; Ayanaba and Dart, 1977
Enormous Growth
⅔ of pool harvested every week
Azolla filiculoides
30 – 45 tonnes DW ha-1 y-1
Glycine max
2-5 tonnes DW ha-1 y-1
Brouwer et al., 2018
PhD Thesis Paul Brouwer, 2017
Technical Feasibility
Growth on 2.5% ADSW
Azolla takes up all nitrogen and phosphorus
1.2 million pigs in The Netherlands
12.4 million tonnes swine manure
40 tonnes Azolla DW ha-1 y-1
6 tonnes manure ha-1 y-1
10 tonnes protein ha-1 y-1
Muradov et al., 2014; Wageningen UR Livestock Research
Summary
Reduce:
• Global problems caused by the Haber-Bosch reaction
• The manure problem in The Netherlands
• CO2-emission caused by large distribution routes
Increase local production of goods such as:
• Bio-fertilizer, animal feed and protein
• Residual plant matter (bio-plastics and peat substitution)
