Summary: This study establishes an integrated life cycle analysis and techno-economic assessment to evaluate costs and carbon footprint impacts of an integrated forest biorefinery that produces lumber, industrial sugar and wood pellets in the Pontiac region of Quebec (Canada). The conclusion of this study is that if the GHG emission is considered as the basis of the ranking system, the production of wood pellets would emit the least amount of greenhouse gases, while lumber and sugar production would emit the most. However, if the ranking is based on cost, the sequence would be lumber production, followed by wood pellets and sugar.

Summary: Many developments in the bioeconomy rely on genetically modified microorganisms (GMMs), but a recent judgment by the Court of Justice of the European Union on gene editing technologies has affected their use. There is a debate on whether GMMs should be considered genetically modified organisms and whether the current regulatory policies on GMMs are justified from a sustainability perspective. This article provides an overview of GMMs and their importance, discusses different scenarios for regulating GMMs in the future, and assesses the potential implications of these scenarios on the objectives of the European Green Deal.

Summary: In this study, we investigate the mechanisms of the attitude-behavior paradox and how different stakeholders navigate between their attitudes and behaviors. Using an instrumental variable probit model, we examine the impact of income heterogeneity and social ties on the farmers' attitude-behavior paradox in collective action. The empirical results reveal that weak and strong ties, income heterogeneity, interaction terms, education, community environment, and community rules have a negative effect on the paradox, while water stealing and water use conflicts have a positive effect. We contribute to understanding how economic incentives and social structures play a role in addressing this paradox. The implications for policy to overcome this social dilemma are discussed.

Summary: Gasification kinetics of six chars from residual origin were studied under relatively low temperature, low CO2, and high H2O partial pressures. The Random Pore Model (RPM) showed the best fit to experimental results, but the selection of the reaction model depended on the ash composition, specifically the presence of alkali and alkaline earth metals. Chars with ash content higher than 30% wt. were modeled with the RPM model, while chars with the highest K/Si ratio required modified versions of the RPM to accurately predict reaction rates. Textural properties played a key role in determining reaction parameters, such as the pre-exponential factor and activation energy, for chars with similar ash content and composition.
