Lignocellulose ethanol

A unique pilot plant for ethanol production from lignocellulose feedstock was inaugurated in O-vik, Sweden in May 2004. The aim of the pilot plant was to develop efficient continuous technologies for the various process steps in ethanol production from forest raw material and other lignocellulosic feedstock. Different raw materials require different conditions during the production process and the process also needs to be optimised for every raw material. Further it was important to demonstrate that large-scale lignocellulose ethanol production was possible... [Pg.171]

Biotechnology could also provide crop varieties better suited to nonfood raw material production. For example, ethanol yield during fermentation of woody biomass is affected by lignin content. Use of GM tree varieties with low lignin contents could increase lignocellulosic ethanol yield by 20% [17]. A further potential benefit of GM technology is the ability to produce large quantities of enzymes for industrial purposes. Development of modified maize plants that express... [Pg.42]

Figure 4.3 illustrates different possible conversion routes for the production of ethylene from biomass. One way to produce ethylene from renewable feedstock is catalytic dehydration of bioethanol. In the short term, it is likely that bioethanol dehydration for the production of ethylene will be established in regions with cheap access to bioethanol, for example, Brazil, where ethanol usage is on the same level as usage of fossil-based fuels (on an energy basis) in the transportation sector. In Europe and the United States, this trend is expected to occur after the commercial introduction of lignocellulosic ethanol (Jones et al., 2010). [Pg.80]

As an example for the industrial application of waste valorization, the enterprise Enerkem opened in Canada a 5-miUion-liter-capacity demonstration bioethanol and biochemical plant in 2012 based on wood. The same company finished in 2015 the constmction of a larger plant (30 million liter) in Edmonton, Alberta, for the production of lignocellulosic ethanol from municipal solid waste. Despite this, production is nowadays focused on methanol, carbon dioxide, and other chemicals that present higher revenues than ethanol due to their lower market prices (Dessureault, 2015). Future plants for the production of cellulosic ethanol from nonrecyclable wastes have also been announced in Quebec, while other Canadian cities will produced clean bio-based heat and power through gasification, pyrolytic bio-oil, etc. [Pg.109]
