Two leading airline companies are collaborating to make sustainable aviation biofuel from a new type of tobacco plant.

This initiative broadens cooperation between South African Airways (SAA) and Boeing to develop renewable jet fuel in ways that support South Africa’s goals for public health as well as economic and rural development.

“South Africa is leading efforts to commercialise a valuable new source of biofuel that can further reduce aviation’s environmental footprint and advance the region’s economy,” said J. Miguel Santos, managing director for Africa, Boeing International.

 

Solaris

SkyNRG, a fuel producer, is expanding production of the hybrid plant known as Solaris as an energy crop that farmers could grow instead of traditional tobacco.

Test farming of the plants, which are effectively nicotine-free, is underway in South Africa with biofuel production expected from large and small farms in the next few years.

Initially, oil from the plant’s seeds will be converted into jet fuel. In coming years, Boeing expects emerging technologies to increase South Africa’s aviation biofuel production from the rest of the plant.

“By using hybrid tobacco, we can leverage knowledge of tobacco growers in South Africa to grow a marketable biofuel crop without encouraging smoking,” said Ian Cruickshank, South African Airways Group Environmental Affairs Specialist. “This is another way that SAA and Boeing are driving development of sustainable biofuel while enhancing our region’s economic opportunity.”

“We strongly believe in the potential of successfully rolling out Solaris in the Southern African region to power sustainable fuels that are also affordable,” said Maarten van Dijk, Chief Technology Officer, SkyNRG.

 

Roundtable on Sustainable Biomaterials

Boeing and SAA are working with the Roundtable on Sustainable Biomaterials to position farmers with small plots of land to grow biofuel feedstocks that provide socio-economic value to communities without harming food supplies, fresh water or land use.

When produced sustainably, aviation biofuel reduces carbon emissions by 50% to 80% compared to petroleum jet fuel through its lifecycle.
