“…The methodology adopted has been shown in detail in the ESI †. A similar methodology has already been reported by Choe et al 24 for conducting uncertainty analysis of the feedstock and adipic acid price from the minimum selling price of butene oligomers. The feedstock (lignin) price and total capital investment were chosen as the parameters in this study since they vary with fluctuations in the market and the results obtained are shown in Fig.…”

“…In this study, we include the production pathways of these seven chemicals and expand them to include the pathways of the remaining eight, completing a holistic evaluation of all 15 chemicals identified by Biddy et al We report life-cycle GHG emissions, fossil energy consumption, and water consumption of these biochemicals compared to contemporary baseline compounds. As biochemicals are often viewed as coproducts of biofuels or coproduced bioproducts, we developed profiles of these 15 biochemicals as potential coproducts that could improve the economics, market prospects, or environmental effects of the main products of bioprocessing. ,− Furthermore, we consider how these 15 compounds in total might reduce the environmental effects of conventional chemical production in aggregate.…”

The urgent need for greenhouse gas (GHG) emission reductions to mitigate climate change calls for accelerated biorefinery development and biochemical deployment to the market as structural or functional replacements for chemicals produced from fossil-derived feedstocks. This study evaluated the energy and environmental impacts of 15 biochemicals with clear near-term market potential and their fossil-based counterparts, when applicable, on a cradle-to-gate basis. Three of these chemicals are produced exclusively from biomass; eight are predominantly produced from fossil-derived feedstocks; and four are predominantly produced from biomass. For the 12 cases that can be produced from either feedstock, eight exhibited fossil energy consumption and GHG emission reductions when produced from biomass instead of fossil-derived feedstocks between 41%−85% and 35%−350%, respectively. Water consumption results were mixed because several of the biobased pathways consumed more water. Annually, replacing the predominantly fossil-fuel-based chemicals with biobased alternatives could avoid 120 MMT CO 2 e emissions and save 1,500 PJ of fossil energy. The potential of these chemicals as coproducts in integrated biorefineries was analyzed in terms of market, economics, and environmental effects with an emphasis on GHG emissions. Adipic acid, succinic acid, acrylic acid, propylene glycol, 1,4-butanediol, 1,3-butadiene, furfural, and fatty alcohol are promising coproduct candidates based on their low life-cycle GHG emissions.

“…Excessive exploitation and consumption of fossil fuel-derived material increasingly accelerates the severe climate change and environmental pollution issue. [1] To address the issues, new technologies utilizing renewable sources are being vigorously pursued. [2] Among the candidates, lignocellulosic biomass, which consists of cellulose, hemicellulose, and lignin, has tremendous potential to produce bioplastic as well as biofuels.…”

2,5-Furandicarboxylic acid (FDCA) is one of the promising renewable plastic monomers enabling to address several environmental issues, instead of petroleum-based terephthalic acid (TPA). In this study, an integrative process for the coproduction of FDCA and furfural as well as activated carbon was developed, and the economic feasibility and environmental sustainability for the proposed process were evaluated. In the proposed process, there were major four catalytic conversion reactions: (1) hydrolysis of biomass to its derivatives (cellulose, hemicellulose, and lignin), (2) dehydration of hemicellulose to furfural, (3) dehydration of cellulose to 5-hydroxymethylfurfural (HMF), and (4) successive oxidation of HMF to FDCA. Partic-ularly, a heat exchanger network coupled with a heat pump was established to minimize the utility consumption, thereby reducing 72 % of the heating requirement. Techno-economic analysis revealed that the minimum selling price of FDCA was $1380 ton À 1 , which is comparable to that of petroleum-based TPA ($1445 ton À 1 ). Uncertainty analysis using the Monte Carlo simulation method was employed to quantify the risk associated with the unforeseen market condition. From the life-cycle assessment, we observed that the proposed process is more environmentally sustainable than conventional TPA production in terms of climate change and fossil depletion metrics.
