Energy crops are crops with a high yield of lignocellulosic biomass produced as a raw material for the production of second-generation biofuel; examples include switchgrass (Panicum virgatum) and elephant grass. The biofuels generated from these energy crops are sources of sustainable energy. [7] [8]
Idealized structure of lignin from a softwood. Lignin is a class of complex organic polymers that form key structural materials in the support tissues of most plants. [1] Lignins are particularly important in the formation of cell walls, especially in wood and bark, because they lend rigidity and do not rot easily.
Cellulose and lignin are two of the primary natural polymers used by plants to store energy as well as to give strength, as is the case in woody plant tissues. Other energy storage chemicals in plants include oils , waxes , fats , etc., and because these other plant compounds have distinct properties, they offer potential for a host of ...
The so-called "third-generation biofuels", similar to second-generation biofuels with an emphasize on the use of algae and cyanobacteria as a source of biofuel feedstocks, have an additional advantage as they take up a relatively small fraction of space when compared to first and second-generation biofuel sources, and may also help to reduce seawater eutrophication.
Biopolymers can be sustainable, carbon neutral and are always renewable, because they are made from plant or animal materials which can be grown indefinitely. Since these materials come from agricultural crops , their use could create a sustainable industry.
The Alpena biorefinery plant in the USA. A biorefinery is a refinery that converts biomass to energy and other beneficial byproducts (such as chemicals). The International Energy Agency Bioenergy Task 42 defined biorefining as "the sustainable processing of biomass into a spectrum of bio-based products (food, feed, chemicals, materials) and bioenergy (biofuels, power and/or heat)".

Iogen Corporation is a Canadian company based in Ottawa, Ontario, Canada, and was founded by Patrick Foody Sr. in 1975. [1]The company develops technology for making renewable cellulosic biofuels (also known as second generation biofuels, or advanced biofuels) from agricultural residues and other organic wastes.
