Biorefineries offer a promising alternative to fossil-based processing industries and have undergone rapid development in recent years. Limited financial resources and stringent company budgets necessitate quick capital estimation of pioneering biorefinery projects at the early stages of their conception to screen process alternatives, decide on project viability, and allocate resources to the ...

Abstract Biorefinery approaches offer the potential to improve economics of microalgae industry by producing multiple products from a single source biomass. Chromochloris zofingiensis shows great promise for biorefinery due high biomass productivity and diverse range including secondary carotenoids, predominantly astaxanthin; lipids such as TAGs; carbohydrates starch; proteins essential amino a...

We develop a novel superstructure of algal biorefinery processes for biological carbon sequestration and utilization, encompassing off-gas purification, algae cultivation, harvesting and dewatering, lipid extraction, remnant treatment, biogas utilization, and algal oil upgrading stages. Based on the superstructure, we propose a mixed-integer nonlinear programming (MINLP) model to minimize the u...

46 J-FOR Journal of Science & Technology for Forest Products and Processes: VOL.1, NO.1, 2011 The extraction of hemicelluloses from wood chips is crucial for producing value-added biomaterials in a forest biorefinery utilization. The low concentration of dissolved lignocellulosic materials dissolved in pre-hydrolysis liquor (PHL) presents a big challenge to the overall utilization processes. In...

In traditional pulping, black liquor is burned in an alkali recovery system to produce energy. According the integrated forest biorefinery (IFBR) concept, hemicellulose partially pre-extracted prior pulp production generate value-added products. Corn stalks have a remarkable carbohydrate content (75% w/w), and thus were examined this study terms of IFBR concept. The hemicelluloses with hot wate...
