From Hemp Bast to Lyocell Fiber: Sustainable Process Optimization for Lyocell‐Grade Dissolving Pulp
This study presents a sustainable method to produce lyocell‐grade dissolving pulp from Canadian hemp bast fibers. A simplified alkali‐chelation‐bleaching process, free from sulfur and chlorine, yielded high α‐cellulose pulp with low lignin and hemicellulose content. The pulp was successfully spun into continuous hemp‐based lyocell fibers, demonstrating

Revisiting acidulation for tall oil and lignin manufacturing
Abstract Tall oil is a byproduct of the kraft pulping process when softwood is used as raw material. As the production of softwood‐based pulp is in high demand, the optimization of the tall oil production process needs to be revisited to ensure the highest quality and quantity of tall oil manufacturing. In this work, the process for tall oil production

Art Adds Value to Ecological Field Courses: A Multi‐Year Case Study in Higher Education
This study presents Earth Projects, an interdisciplinary, place‐based field course that merges ecology and ecological art (eco‐art) to foster deeper engagement with environmental learning. Pre‐ and post‐survey comparisons show that incorporating eco‐art can strengthen students' emotional connections to their identities, disciplines, and place.
