Aflasafe Pilot Plant Objectives

Demonstration-scale plant to be used as a model to:

• Optimize and adapt the manufacturing process

• Reduce aflasafe manufacturing cost

• Produce axenic Bio pesticide

• Model turn-key facility for replication in other countries

• Demonstrate commercial viability for mass production

of Aflasafe and recruit commercial partners.

Scaling Up

Lab & manufacturing Plant core processes:

Production of the inoculum

Production of the substrate/carrier

Inoculation/Coating

Packaging (weighing, sealing and labelling)

Current (Lab) production process 1.2 t/wk (300kg/day)

Manufacturing Plant:

• Mechanise Lab Production

• Scaled up to 5t/hr

• Simplify production

o Cleaning

o Sterilisation – dry process and cost reduction

o Inoculation – coating

o Packaging – simple and cheap

Conclusion

• Commercialization: 2 investors ready

• Conclusion

• Roasting has proven viable to kill and sterilize aflasafe TM substrate.

• The production facility can be cleaned to a microbiological

standard using hot, roasted grains.

• aflasafe TM produced in this facility meets rigorous standards, at a

lower cost, and using commercially available equipment.
