Advancements in Algal Harvesting Techniques for Biofuel Production

Algal Biofuels

Abstract

Increasing population and severe energy crisis has confronted into an ill-shaped economy worldwide. The need of this hour is to research upon new alternative technology, which not only fulfils the energy requisites but also look after the cost-effectiveness and environmental safety. Biofuel production, from several organic substrates or biomass, is one such technology which has recently gained importance. Algae are simple micro-organisms which have been proved to be a highly potent feedstock for biofuel production at lab-scale conditions. However, the pilot scale and commercial scale utilization of this high value organism is not very feasible as highly stable suspensions of algae do not permit easy separation or its concentration/dewatering. These separation techniques are either successful only at low scale or require high energy inputs for large scale separation, which is very much uneconomical. This paper reviews several approaches of algal harvesting and its advancements for reducing the process cost as well as increasing the biomass yield.
