Nowadays, efforts to reduce atmospheric CO2 emissions and the increasing concern about the availability of fossil raw materials has led the chemical industries to search for alternative bio based feedstock for acrylic acid production.
For this reason that we are investigating the use of renewable, biomass feedstock as a basis for a sustainable and large-scale production process of "green" acrylic acid. 
Lactic acid (2-hydroxypropanoic acid) can be produced biotechnologically via fermentation of carbohydrates (sugar, starch) and can further be catalytically dehydrated to acrylic acid. Lactic acid produced by fermentation combines low production cost and minimization of oil consumption. Therefore, it represents an attractive and environmentally friendly alternative as feedstock for the production of bio acrylic acid.
