“…Himmel et al (2007) and Harris & DeBolt (2010) have proposed the development of crops with increased potential biofuel yield from the straw (referred to in this study as digestibility). Phitsuwan & Ratanakhanokchai (2014) consider the development of Elite Rice that has improved grain yield, straw yields and digestibility plus improved lodging resistance. Nasidi et al (2015) compared sorghum cultivars for use as feedstock for SGB production by considering biomass yield and digestibility.…”

Food and bioenergy: reviewing the potential of dual‐purpose wheat crops

Within the bioenergy debate, the ‘food vs. fuel’ controversy quickly replaced enthusiasm for biofuels derived from first‐generation feedstocks. Second‐generation biofuels offer an opportunity to produce fuels from dedicated energy crops, waste materials or coproducts such as cereal straw. Wheat represents one of the most widely grown arable crops around the world, with wheat straw, a potential source of biofuel feedstock. Wheat straw currently has limited economic value; hence, wheat cultivars have been bred for increased grain yield; however, with the development of second‐generation biofuel production, utilization of straw biomass provides the potential for ‘food and fuel’. Reviewing the evidence for the development of dual‐purpose wheat cultivars optimized for food grain and straw biomass production, we present a holistic assessment of a potential ideotype for a dual‐purpose cultivar (DPC). An ideal DPC would be characterized by high grain and straw yields, high straw digestibility (i.e. biofuel yield potential) and good lodging resistance. Considerable variation in these traits exists among current wheat cultivars, facilitating the selection of improved individual traits; however, increasing straw yield and digestibility could potentially have negative trade‐off impacts on grain yield and lodging resistance, reducing the feasibility of a single ideotype. Adoption of alternative management practices could potentially increase straw yield and digestibility, albeit these practices are also associated with potential trade‐offs among cultivar traits. Benefits from using DPCs include reduced logistics costs along the biofuel feedstock supply chain, but practical barriers to differential pricing for straw digestibility traits are likely to reduce the financial incentive to farmers for growing higher ‘biofuel‐quality’ straw cultivars. Further research is required to explore the relationships among the ideotype traits to quantify potential DPC benefits; this will help to determine whether stakeholders along the bioenergy feedstock supply chain will invest in the development of DPCs that provide food and fuel potential.

“…High yielding food crops such as rice, an important cereal crop of Asia with abundant residuals (polysaccharide-rich straw), are received by advanced genetic engineering techniques, to precisely manipulate the regulating mechanisms of grain production, cellulose and lignin content, and stress tolerance, and to enhance biomass saccharification. They could effectively generate biomass feedstock for animal feed and bioenergy production, reducing conflicts over land use (Phitsuwan and Ratanakhanokchai, 2014). Genetic engineering and synthetic biology have modified plant composition, to reduce conversion process cost or to develop and produce perennial feedstock with desired traits, reaching very quickly high energy capacities by spending lesser fertilizers and water (Simmons et al, 2008).…”

“…Numerous industrial materials, including dyes, solvents and synthetic fibers, have been manufactured from trees and cultivated crops at the beginning of 20 th century, while many of them had been substituted by derivative products of petroleum by the late 1960s (Ragauskas et al, 2006). The use of limited arable land for food and bioenergy production remains a controversial issue (Phitsuwan and Ratanakhanokchai, 2014). Marine plants (macroalgae) only need seawater, sunlight and carbon dioxide to grow much faster than terrestrial plants, not encroaching on land required for food crops (Walker, 2011).…”

Since early human history and existence energy rich plants, wood and forest cellulosic material have been used for fire, light, heating, cooking and other daily activities. Fossil energy was the foundation of our modern society and industrialization since last two centuries, while exploration and exploitation of oil reserves and petrochemistry have largely shaped 20th century. Increasing concerns on environmental pollution, accelerated global warming, and global climate changes, continuing world's crude oil (fossil fuels) consumption and depletion, as well as energy security and energy crisis caused by daily burning large amounts of fossil fuels, led to the attraction, search and development of renewable, carbon-neutral, economically viable alternative energy sources, such as biofuels, slowly displacing petroleum fuels. In continuously growing human population reaching about 10 billion in 2050, various renewable energy sources are promoted and developed, to ensure rising energy demands in a world running out of fossil energy sources. Biofuels are produced from any kind of available biomass and categorized based on utilized carbon resources into first-, second- and third-generation. Nevertheless, biofuels’ future outlook is though beset by uncertainty. Hereby, various issues and concerns related to fossils and renewable biofuels are described and analyzed in present review article.

“…It is considered the third most produced crop after maize and wheat on the planet (Mauryaet al, 2017), and it is the most important food crop in Asia (Clauss et al, 2017). Rice is also a multifunctional crop, which can be used as food, feed, and feedstock for bioenergy production (Phitsuwan and Ratanakhanokchai, 2014). Italy is the main rice producer in Europe with an area of 234,133 ha and the amount of rice production of over 1.5 million tons (Graziano et al, 2020).…”
