Bioethanol generation plant

Plant Raw Materials for Use in First-generation Bioethanol Production... 

Currently, biodegradable plastics are considered to be eco-friendly because they can be broken down by the action of microorganisms in the environment. However, from the viewpoints of raw materials and energy sources, bio-based polymers have been produced from plant biomass. Unfortunately, at this point, bio-based polymers produced from edible sources such as com and sugar can generate new social problems. Furthermore, since bio-polyethylene has already been produced from bioethanol, some bio-based materials are not biodegradable plastics. 

Figure 2 An illustration of the various research activities underway to develop the next generation bioethanol plant. The 3 key areas of R D are in pretreatments, enzyme hydrolysis andfermentations. Significant efforts focus on process engineering cmd plant designs with the following at the core SHF -separate hydrolysis and fermentation, SSF - a simultaneous saccharification-fermentation, or SSCF - a simultaneous saccharification-cofermentation.

Currently, in the first generation of bioethanol, food crops such as com, sugar cane, and wheat are used for the production of energy. These are starch- or sucrose-rich feedstocks that are readily fermented by microorganisms. However, these crops are also used for food and feed production, resulting in competition. At present, commercial production of the first-generation biomass utilizes readily-available sugars from these food plants for the fermentation process of biofuel production.
