“…Since this may result in depletion of crude oil reserves in the world, it is imperative to consider energy sources alternative to crude oil [ 7 ]. Biofuels and biochemicals produced using nonedible feedstock such as lignocellulosic biomass provide several benefits to the society [ 8 ] like (i) being renewable and sustainable, (ii) indirectly helping carbon dioxide (a greenhouse gas (GHG) that is responsible for global warming) fixation in the atmosphere, (iii) facilitating local economy development and stimulation, (iv) reducing air pollution from burning of biomass in fields and biomass rotting in fields, (v) bringing energy security for countries dependent on imported oil, and (vi) creating high technology jobs for engineers, fermentation specialists, process engineers, and scientists. In the fifties when petroleum processing was invented, the cost of feedstock was cheaper, but the processing costs were higher.…”

Current Challenges in Commercially Producing Biofuels from Lignocellulosic Biomass

Biofuels that are produced from biobased materials are a good alternative to petroleum based fuels. They offer several benefits to society and the environment. Producing second generation biofuels is even more challenging than producing first generation biofuels due the complexity of the biomass and issues related to producing, harvesting, and transporting less dense biomass to centralized biorefineries. In addition to this logistic challenge, other challenges with respect to processing steps in converting biomass to liquid transportation fuel like pretreatment, hydrolysis, microbial fermentation, and fuel separation still exist and are discussed in this review. The possible coproducts that could be produced in the biorefinery and their importance to reduce the processing cost of biofuel are discussed. About $1 billion was spent in the year 2012 by the government agencies in US to meet the mandate to replace 30% existing liquid transportation fuels by 2022 which is 36 billion gallons/year. Other countries in the world have set their own targets to replace petroleum fuel by biofuels. Because of the challenges listed in this review and lack of government policies to create the demand for biofuels, it may take more time for the lignocellulosic biofuels to hit the market place than previously projected.

“…The complexity of bioenergy production systems will require considerable research to achieve renewable energy solutions that are truly sustainable (Greenwell et al 2012), and we agree with Robertson et al (2008) that the identification of potential problems early in the development of renewable biofuel strategies will help to avoid costly mistakes. Although homogeneity of biofuel inputs may facilitate biofuel processing, monoculture-based biofuel production may ultimately prove to be unsustainable.…”

“…Regarding the technological criteria, there are criteria associated with the efficiency of transformation processes and the technical feasibility of technologies implemented, but a lack of criteria that link the efficiency and the technical feasibility with the environmental and social impacts of the biodiesel supply chain. Finally, the relationships and influences among stakeholders (socio-technical system approach Greenwell et al 2012) with the biodiesel supply chain was weakly analysed.…”

Sustainability assessment of biodiesel production is a topic of increasing importance due to the interest of governments to define sovereignty strategies and diversification of their energy matrix, and to set up the impact of biofuels production. In this context, this work aims to propose a hierarchical structure of sustainability assessment that integrates dimensions of sustainable development with principles, criteria and indicators (PC&I). The method employed to define the hierarchical structure was a comprehensive literature review, based on information search strategy and classification. About 400 documents were reviewed and 103 documents were ultimately selected, including laws, policy documents, certificates, directives and other normative documents and papers published in peer-reviewed journals. The first result of the analysis was the need to strengthen identification of the sustainable development assessment, adding the political and technological dimensions to the three traditional dimensions, social, economic and environmental, studied in this kind of evaluation. The second result was the proposal of a hierarchical framework for the sustainability assessment of biodiesel production, organized in four levels: the first level comprises the five dimensions associated with sustainable development evaluation, the second includes 13 principles, the third contains 40 criteria and the fourth level corresponds to a set of indicators that describes each criterion. Outcomes of this work provide a foundation for further discussion of sustainability assessments for biodiesel production and its potential application in specific contexts.
