Turning science into industrial reality

Reducing our Greenhouse Gas (GHG) emissions and our dependence on fossil resources is a major challenge of this century. Fermentation is an economically viable route for substituting petro-based molecules — whether producing renewable fuels, such as ethanol, or drop-in molecules for industrial production. Lesaffre develops fermentation solutions for industrial manufacturers looking to reduce their environmental footprint.

From biomass to fuel ethanol

Renewable ethanol is produced by yeast fermentation from the conversion of carbon-based feedstocks including sugar cane, sugar beets, corn, wheat, rice or cassava, among others, as well as from waste and agricultural residues. Starch or ligno-cellulosic substrates are required to break down the feedstock into fermentable sugars, using various pre-treatment and enzyme technologies.

Used together with gasoline, fuel ethanol reduces CO2 emissions and helps to improve air quality. Lesaffre, with its business unit Leaf, develops new yeast strains that unlock the potential of local alternative feedstocks, and improve yield and productivity for ethanol producers.

 

Promoting a sustainable economy

Bio-based products aim to capitalize on biomass to reduce our dependence on the fossil resources that negatively impact global warming. The challenge lies in developing more eco-friendly production processes that reveal the potential of natural resources, which are sometimes under-exploited. We believe in the potential of fermentation to address this issue. We work with our partners to develop economically viable fermentation solutions for deployment in the bioeconomy.

Our commitment to the bioeconomy has led us to create a dedicated business unit: Leaf.

Making our mark in the bioeconomy

Leaf provides our industrial ethanol partners with a comprehensive range of yeasts and yeast products, complemented and supported by a team of technical experts in conventional and advanced ethanol production. We rely on our application lab, called Green Lab, to improve ethanol production knowledge and to optimize our partners’ production processes. Our business unit also offers advanced fermentation services, by sharing our distinctive competencies and capabilities with our partners at each step of their projects: from yeast strain engineering, fermentation process scale-up and optimization through to industrial-scale manufacturing of yeast biomass.

Since 2014, Leaf has been committed to reinforcing the Group’s current market position on the conventional and cellulosic ethanol markets. Through teamwork and industrial partnerships, Leaf will also develop economically viable solutions for bio-based chemical production. In addition to these partnerships, we collaborate with universities, institutes and technical centers that are experts in their fields. With dedicated sales, technical, marketing and regulatory staff around the world, Leaf is focused on turning science into industrial reality.
