“…Sweet sorghum stems were explored in biorefinery to generate multiple valuable products, such as ethanol, butanol and wood plastic composites (Yu, Zhang, Zhong, Zhang, & Tanet, 2012). Plant oils contains various triacylglycerol based on fatty acids with 8-24 carbon length chains (Octave & Thomas, 2009). Oilseeds provide a unique opportunity for the production of biofuel and high-value fatty acids that can replace petrol sources of specialty chemicals, lubricants and detergents.…”

Biomass, as a renewable resource, has the potential to decrease our dependence on fossil fuels, provide energy security and mitigate environmental problems. Shifting dependence from petroleum-based to renewable biomass-based resources is generally viewed as key to the sustainable development and effective management of greenhouse gas emissions. There has been an increasing research interest in the assessment of bio-sourced materials recovered from residual biomass and their conversion techniques. Biomass which is generally considered as less important due to its light weight, bulkiness and less economic value can be a valuable feedstock in biorefineries. Many countries of the world are now on the way to effectively utilizing the so called neglected energy source for achieving greater and cleaner energy efficiency by adopting biorefinery approach. This review paper hereby critically examine the idea of biorefineries as a strategy for sustainability by using different available biomass feedstocks, techniques for their multipurpose conversion into useful chemicals, fuel and materials, and the associated challenges on the basis of relevant researches.

Abstract:The role of biorefineries in the production of energy and chemicals from biomass of lignocellulosic nature is reviewed. Special attention is devoted to biorefinery schemes dealing with the fractionation of lignocellulosic raw materials by chemical treatments. The potential of hydrothermal treatments as the first stage of future biorefineries is discussed. Special attention is devoted to the low-volume, high-added value products that can be solubilized by this type of technology.

Fuel blends, particularly those composed of a mixture of biobase and fossil sources, are comparatively new in the energy marketplace relative to pure fossil fuels such as gasoline or pure biobase fuels such as sugarcane‐derived ethanol. A developing market exists for these blends of biobase and fossil fuels and accompanying this is the need for accurate assessment of each source's contribution in the mixture. In the United States, the Energy Independence and Security Act of 2007 mandates that specific levels of renewable fuel be established by 2022. Currently, this requirement is met by the 10% ethanol, derived primarily from corn, which is added to most gasoline sold in the United States. This mandate requires that the accurate determination of this addition of renewable fuel be provided. The well‐developed technology of radiocarbon dating, measuring the abundance of the 14 C atoms in a material, can determine the source material based on the abundance or absence of 14 C, similar to but distinct from age determination in radiocarbon dating. Relative to other analytical techniques, 14 C determination is the only one able to unambiguously determine a fossil‐fuel‐derived product. The use of radiocarbon, as a determinant of a biobase product, stems from the natural occurrence of 14 C in plants as a result of 14 CO 2 uptake during photosynthesis along with the far more abundant stable isotopes of carbon 13 CO 2 and 12 CO 2 . Once harvested, the biobase source material such as corn or sugarcane will no longer take up 14 CO 2 and will retain the majority of the 14 C absorbed with only a minor loss through the continuous process of radioactive decay. 14 C has a half‐life of 5730 years, the time required to halve the 14 C content, and becomes undetectable, or indiscernible from background activity, after approximately 10 half‐lives or 57 000 years. Carbon‐containing materials older than this have no measurable 14 C activity and are considered fossil in origin. This is a far shorter time than is required for the maturation of petroleum hydrocarbons or other fossil fuels so they are in essence at or below background 14 C activity by the nature of their long‐term formation. This paper discusses the use of 14 C and stable isotope of carbon to determine the mixing of biobase and fossil fuel‐derived materials.
