Algae grown for biofuel,light micrograph. Algae are photosynthesising micro-organisms that can convert carbon dioxide into large amounts of lipids. The lipids can be converted into biodiesel by reacting with alcohol,a process known as transesterification. Unlike fossil fuels,biodiesel is biodegradable and non-toxic. However it is more costly to produce. Algae can also be cultivated to produce pharmaceutical products,dyes and edible oils,or dried and used as fertiliser or burned as biomass | |
