Algal biomass – a viable source for biogas and biodiesel
Journal Title: Scientific Annals of the Danube Delta Institute - Year 2014, Vol 20, Issue
Abstract
Algal biomass has been found to contain high levels of lipids and high quality polyunsaturated fatty acids, as well as many other organic compounds, that made this wide spread natural resource to be of great interest in the production of valuable biofuels, such as biogas and biodiesel. Paper aims to point out some socio-economical advantages that algal biomass could bring to small and large communities, if such organic materials are collected to be used for production of biofuels such as biogas and biodiesel. There are also mentioned the environmental benefits of algae-based technologies and the role of algal biomass in sequester CO2 emitted from conventional fuel fired power plants, thus reducing the emission of greenhouse gases into the atmosphere. One innovative technical solution for producing biogas using a wide range of wet biomass generated in small farms, as well as algae and aquatic waste have been shown. Some benefits of biogas technology both for energy sector and environment protection, but also for supplying alternative fuel to be used for domestic applications in isolated communities have been shown. Main direct applications of this biogas technology which use algae and other organic substrates, to produce biogas and ecological soil fertilizers, but also their contribution to improve life quality of people living in isolated villages in delta area, have also been presented. Besides biogas applications, some technical solutions for harvesting and extraction of oils from freshwater and marine algae to produce biodiesel and other useful materials have been briefly mentioned.
