Comoros the Nr.1 worldwide in distillation of Ylang-Ylang. Traditional distillation used wood as fuel, but this resource is very limited on the tropical islands with growing population.
For our partner 2 Mains Comoros we developed a concept of solar distillation for Ylang-Ylang.
Steam for the distillation is generated by Photovoltaic panels. The back-up for the solar power supply is a very efficient biobriquette burner implementing improved combustion. 2Mains is engaging in the production of bio-briquettes from organic waste in a project improving wastemanagement on the islands of Comoros. The bio-briquettes are planned to replace wood for distillation. Our improved biomass burner can handle bio-briquettes as well as wood and coconut waste.
As a first step of technology implementation a 200ltr distillation unit with bio-briquette burner for steam generation was installed and tested in December 2015 in a renowned distillery on Gran Comore.
The steam flow is can be set independently of the intensity of the fire. It remains constant throughout distillation. Excellent quality of Ylang-Ylang oil and low consumption of biomass prooves this new concept to be successful. The smokeless combustion improoves the working environment of the destillers and reduces pollution.

The right amount of air and correct ratio between primary
and secondary combustion guarantee an energy efficient
and smokeless fire


In a further project phase the complete concept of solar distillation will be implemented.
