This reference book describes how bioprocessing and biotechnology could enhance the value extracted from wood-based lignocellulosic fiber by employing both biochemical and thermochemical conversion processes. It documents recent accomplishments and suggests future prospects for research and development of integrated forest biorefineries (IFBR) as the path forward for the pulp, paper and other fiber-processing industries. This is the only book to cover this area of high economic, social, and environmental importance. It is aimed at industrialists and academics from diverse science and engineeri.

The Canadian Pulp and Pulp (P&P) industry has been recently confronted by shrinking markets and tighter profit margins. Transforming P&P mills into Integrated Forest Biorefineries (IFBR) is a prominent solution to save the struggling industry and allow diversification towards the promising bioproducts markets. The implementation of such a strategy is a complex process that faces many sources of uncertainty. Therefore, the industry is in need for a planning tool that facilitates the IFBR network design by taking the uncertain market conditions into consideration. First, we propose a mixed integer programming model to optimize the investment plan in addition to other tactical decisions over a long term planning horizon. We test the model using a realistic case study for Canadian P&P companies, where we perform a set of sensitivity analysis tests in terms of bioproduct demand and energy prices. Our results showcase the potential of the IFBR to help the P&P industry and highlight the substantial impact of the bioproduct demand on its profitability. Second, we develop a Multi-stage Stochastic Programming model which explicitly incorporates the demand uncertainty. We also develop a simulation platform to validate the model and compare its performance with alternative decision models. We assess the value of incorporating demand uncertainty in the planning process and we also elaborate on the value of flexibility in terms of adjusting the investment plan in response to changes in market trends. Our results demonstrate the significant value of explicitly incorporating the uncertainty in IFBR network design as well as flexibility in the investment plan.

"Biopolymers can provide environmentally friendly alternatives to the use of fossil fuel derived polymers. Among others, their production can be net carbon negative and their disposal can help fertilizing soil by composting. However, the environmental benefits of these biopolymers are largely untapped as their overall production capacity is marginal. This low production is primarily caused by their high production cost and selling price, which hinder most biopolymers to compete on the market. One of the most promising, yet expensive biopolymers are the microbiologically produced polyhydroxyalkanoates (PHAs), since they are compostable and also biodegrade in the marine environment. Furthermore, the currently used raw materials for their production (corn starch and vegetable oils) are not only expensive, but also compete with food production. Alternatively, in Canada, wood is abundantly available through the pulp and paper infrastructure, with residues which can be fed to modern biorefineries. This work explores the feasibility of integrating the most well-known PHA, polyhydroxybutyrate (PHB), into forest biorefineries using the bacterium Paraburkholderia sacchari.For this work, the first forest biorefinery scheme was based on the hydrolysis of softwood hemicellulose as a feedstock for PHB production. Softwood cellulose and lignin were recovered to be further converted into other products. Softwood hemicellulose has a favourable composition as compared to most other hemicelluloses, as it has a high share of the six carbon sugars mannose, glucose and galactose. Mannose and galactose were tested as carbon sources for P. sacchari for the first time and showed maximum specific growth rates of 97% and 60% relative to glucose, respectively. However, the presence of inhibitory compounds (acetate, 5 hydroxymethylfurfural, furfural and phenols) inhibited all bacterial growth. It was found that the inhibition comes from strong synergistic effects when the inhibitors are present in mixtures, and the magnitude of the effects was quantified with a mixture design model. Albeit the initial inhibition could be overcome by a high initial cell density (optical density ≥ 5.6) when using a simulated softwood hemicellulose hydrolysate, this approach was not successful for real softwood hemicellulose hydrolysate. Nevertheless, when the hydrolysate was added as a feed solution after an initial growth phase of 24 h, the sugars were all consumed. In comparison with an inhibitor-free hardwood hydrolysate, the growth rate and PHB yield were lower with softwood hemicellulose hydrolysate. While the sugar composition of the hydrolysate was therefore promising for PHB production, the inhibitory effect currently makes it unsuitable as the carbon source.The second biorefinery scheme studied was based on a pilot plant process developed by FPInnovations using hardwood biomass. The process converts hardwood cellulose and hemicellulose into a holocellulose hydrolysate, which was used as carbon source for PHB production. Using this hardwood hydrolysate in shake flask fermentations increased the maximum specific growth rate and PHB accumulation of the bacterium as compared to simulated hydrolysates. In high-cell density bioreactor fermentations, the wood hydrolysate afforded one of the highest PHB concentrations to date from lignocellulosic biomass. The chemical composition, thermal transitions and viscoelastic properties were similar to literature values of PHB. The number average molecular mass was 246.4 kDa with a PDI of 3.29. These results make PHB from hardwood hydrolysate, as co product with H lignin, a sustainable production scheme for industrial PHB production"--
