Ozonolysis of lignocellulosic biomass using low energy microplasma reactors

Rising concern over depleting fossil fuel and greenhouse gas emissions from fuel combustion has led to a high level of interest in biofuel production, in particular bio-ethanol. Currently, the main producers of bioethanol use food crops as the main raw material. However, use of food sources for biofuel production is not sustainable and research efforts are now shifting to lignocellulosic biomass as a renewable source of fermentable carbohydrate which does not compete directly with food production.

In this project, we will investigate the feasibility of applying a novel ozonolysis pre-treatment method for various lignocellulosic feedstocks. We will use a recently developed microplasma reactor for producing ozone at room temperature and atmospheric pressure that consumes less power compared to conventional methods for this purpose. - Dr Hemaka Bandulasena
