Some Cellulosic Plants around the World

As of 2013, cellulosic ethanol industry has approached a rapidly developing phase. A number of entrepreneurs and companies who believed in currently available technologies have invested

in building commercial-scale cellulosic ethanol plants, mostly in Europe and North America. Due to many reasons, it is not easy to give accurate statistics or a current status report of a series of privately owned industries. However, anybody who is paying attention to renewable energy issues and the biofuel industry is interested in learning about the progress in the cellulosic ethanol arena. Thus, currently operating and under-construction plants around the world are listed in Table 17.6.
