“…First, the investment cost was approximated by using a theoretical capital index, which was based on the stoichiometric heat of reactions and relied on a correlation found between the investment cost and the overall energy transfer duty for fuel and chemical manufacturing processes. [68][69][70] Second, the CO 2 emission of the upgrade was approximated by the CO 2 emission related to the production of fossil H 2 that was needed in the hydrogenation steps. This CO 2 contribution was expected to dwarf all other CO 2 contributions during the upgrade, for example, those from process energy.…”

Furfural—A Promising Platform for Lignocellulosic Biofuels

Furfural offers a promising, rich platform for lignocellulosic biofuels. These include methylfuran and methyltetrahydrofuran, valerate esters, ethylfurfuryl and ethyltetrahydrofurfuryl ethers as well as various C(10)-C(15) coupling products. The various production routes are critically reviewed, and the needs for improvements are identified. Their relative industrial potential is analysed by defining an investment index and CO(2) emissions as well as determining the fuel properties for the resulting products. Finally, the most promising candidate, 2-methylfuran, was subjected to a road trial of 90,000 km in a gasoline blend. Importantly, the potential of the furfural platform relies heavily on the cost-competitive production of furfural from lignocellulosic feedstock. Conventional standalone and emerging coproduct processes-for example, as a coproduct of cellulosic ethanol, levulinic acid or hydroxymethyl furfural-are expensive and energetically demanding. Challenges and areas that need improvement are highlighted. In addition to providing a critical review of the literature, this paper also presents new results and analysis in this area.

“…Furthermore, the production cost is also influenced by the simplicity in the route of feedstock conversion to final product, e.g. feedstocks such as vegetable oil may be expensive (US $ 13-18/GJ or US $ 500-700/t DM), but they are easy to convert, whilst lignocellulose may be cheap (US $ 2-4/GJ or US $ 34-70/t DM), but is very difficult to convert [109,110]. Similar variations in the production economics can be assumed to occur with the biochemical routes under the similar technological constraints.…”

Abstract:The aim of the current paper is to discuss the sustainability aspect of biorefinery systems with focus on: biomass supply chains, processing of biomass feedstocks in biorefinery platforms and sustainability assessment methodologies. From the stand point of sustainability, it is important to optimize the agricultural production system and minimize the related environmental impacts at the farming system level. These impacts are primarily related to agri-chemical inputs and the related undesired environmental emissions and to the repercussions from biomass production. At the same time, the biorefineries needs a year-round supply of biomass and about 40-60% of the total operating cost of a typical biorefinery is related to the feedstocks chosen, and thus highlights on the careful prioritization of feedstocks mainly based on their economic and environmental loadings. Regarding the processing in biorefinery platforms, chemical composition of biomasses is important. Biomasses with higher concentrations of cellulose and hemicelluloses compared to lignin are preferred for bioethanol production in the lignocellulosic biorefinery, since the biodegradability of cellulose is higher than lignin. A green biorefinery platform enables the extraction of protein from grasses, producing an important alternative to importing protein sources for food products and animal feed, while also allowing processing of residues to deliver bioethanol. Currently, there are several approaches to integrate biorefinery platforms, which are aimed to enhance their economic and environmental sustainability. Regarding sustainability assessment, the complexities related to the material flows in a biorefinery and the delivery of alternative biobased products means dealing with multiple indicators in the decision-making process to enable comparisons of alternatives. Life Cycle Assessment is regarded as one of the most relevant tools to assess the environmental hotspots in the biomass supply chains, at processing stages and also to support in the prioritization of any specific biobased products and the alternatives delivered from biorefineries.Keywords: biorefinery, biomass feedstock, sustainability, biobased product, environmental performances, economic performances, Life Cycle Assessment 2 IntroductionThe societal need of energy and materials is predicted to reach a crisis point in the near future [1]. This is because of the coupling between escalating demand and cost of fossil fuels upon which the production of chemicals, materials and energy conversions still depend. The high energy intensity in material production has sustainability impacts on the energy sector, environment and economy [2]. Currently fossil fuels contribute about 80% of the global energy demand, and even if the current political commitments and strategies to tackle the issues of climate change and energy insecurity, as envisioned by different countries are in place, the global energy demand in 2035 is still projected to rise by 40% with fossil fuels contributing 75% [3].

“…It has been reported that a cost-reduction of 25% in syngas production would allow the gas-to-liquids processes to become more competitive with oil refining [3]. Developing catalysts and processes that operate at low steam/carbon and/or oxygen/carbon ratios would have a significant impact on the cost of syngas production.…”
