• Editorialpp 2464–2467Kitaoka, T. (2025). "Nanocellulose targets regenerative medicine," BioResources 20(2), 2464–2467.AbstractArticlePDF

  The term “nanocellulose” encompasses a wide range of cellulose-derived nanomaterials, which are characterized by their diverse morphologies and chemical structures at the nanometer scale. In recent years, there has been a remarkable increase in the use of nanocellulose in regenerative medicine. Of particular interest is the in vitro culture of pluripotent stem cells, which has led to a growing demand for animal-free media and scaffolds in stem cell culture. Extracellular matrix (ECM) plays a pivotal role in regulating the proliferation and differentiation of stem cells, with fibrous collagen and glycosaminoglycans serving as structural and functional supports. In this context, nanocellulose has garnered significant interest as potential ECM mimetics, due to its rigid fiber form and its regular interfacial structures. The use of natural polysaccharide nanofibers would represent a promising avenue for the functional design of animal-free cell culture scaffolds, with the potential to significantly advance the regulation of stem cell culture in regenerative medicine.

  Phytochemicals are non-nutritive plant components having bioactive activities. Compared with synthetic chemicals, phytochemicals have numerous advantages, and they are now widely used in health foods, cosmetics, and pharmaceuticals. Phytochemicals also provide a rich natural resource pool for new health food and medicine development. Because of their wide uses, phytochemicals have high economic value for their development and utilization. Phytochemicals are present in a vast number of plants, and their production has a wide range of feedstock sources. In traditional biomass processing, phytochemicals are often considered as wastes and are not recovered. In order to improve the economic benefits, the extraction of phytochemicals has now become an attractive sub-process during the biomass processing. However, the low content of phytochemicals in plants makes their extraction challenging. Efforts are needed to increase the phytochemical content in plants and develop more efficient extraction and separation processes. This editorial briefly discusses phytochemicals and their extraction to improve the economic benefits of biomass processing.

Dr. Hart provided opportunities for young scientists to achieve their goals and provided them with a safe space to learn within research.

• Editorialpp 7–10Zhang, J. (2025). "Barrier molded fiber products based on recovery and up-cycling of paper and agricultural wastes via a Pickering emulsion approach," BioResources 20(1), 7–10.AbstractArticlePDF

  To reduce plastic pollution, it is of interest to develop biodegradable molded fiber products from recovered cellulose-containing residues as an alternative to single-use plastics. Primary questions to be addressed include how to compound molded fiber products from the recycling of paper or cardboard and agricultural residual wastes via combined vacuum thermo-forming and post-drying or synergistic cold and hot press approaches. In addition, consumers will have high expectations regarding barriers for moisture and grease. It is proposed here to produce uniform barrier molded fiber products via a Pickering emulsion approach with chemically recycled waxes from thermolysis of waste polyolefins. It is further proposed to develop a closed-loop process for recyclable molded products and up-cycling lignocellulosic fibers reinforced biomass-derivable vitrimer bio-composites for sustainable packaging. The development of molded fiber products makes it possible to mitigate the usage of single-use plastics.

• Editorialpp 21-24Hubbe, M. A. (2025). "Nanocellulose addition to paper and the ‘Cai Lun Principle’ – Maybe not such a good idea after all," BioResources 20(1), 21–24.AbstractArticlePDF

  Family groups in the ancient cultures of China, Korea, and Japan have toiled for generations in an effort to out-compete their neighbors in the pursuit of handmade paper products having better strength performance, in addition to flatness, uniform appearance, and other desirable attributes. Study of the history of the papermaking craft reveals a remarkable ability of ancient peoples to discover advantageous ways to prepare the cellulosic pulp, to improve its brightness, and to form uniform and strong paper sheets. But though the ancients knew how to “beat” the pulp to improve its bonding ability, there is no evidence of any of them having attempted to greatly “over-beat” some of the fiber, thus making nanocellulose, for potential addition to the fiber mixture. Why not? In this editorial, it is proposed that the ancients may have discovered that adding very highly fibrillated cellulose material to paper was not a good idea.

• Editorialpp 6961–6963Wang, J. (2024). “Machine learning applications in biomass supply chain management and optimization,” BioResources, 19(4), 6961–6963.AbstractArticlePDF

  Forest and biomass resource utilization for bioenergy and bioproducts is crucial for mitigating climate change and promoting a sustainable bioeconomy. Given that the biomass supply chain is a complex system, one of the most concerning issues is selecting and using appropriate modeling and analytical technologies to optimize the advantages of multi-feedstock biomass supply chains. Machine learning (ML) can enhance biomass supply chain management (BSCM) efficiency and sustainability. It can address the complexities in cultivation, harvesting, preprocessing, storage, transportation, and conversion. ML workflows involve data collection, preprocessing, model training, and optimization, using algorithms for prediction and decision-making. Accurate supply and demand forecasting via ML improves production planning and inventory management. Despite its potential, ML applications in BSCM need to deal with challenges such as data availability and quality, interpretability of models, and their generalization capabilities. Overcoming such challenges requires interdisciplinary efforts in data management and model development to fully leverage ML’s applicability.

   

• Editorialpp 6964–6966Nikinmaa, M., Pal, L., and Hubbe, M. A. (2024). "Sustainability as a driver in US and EU in paper and nonwoven sectors," BioResources 19(4), 6964–6966.AbstractArticlePDF

  The US and the EU have adopted contrasting pathways in their pursuit of increased sustainability. This editorial highlights such contrasts with respect to paper and nonwovens products. The American way, at least at the federal level, depends on consumer input, which can have an impact on corporate decisions and practices. Progress with respect to sustainability in the European Union has a higher reliance upon regulations. Each approach has merits as well as deficiencies. A regulation-dependent approach sometimes just moves problems to other parts of the world. A consumer-driven approach does not have a good way to deal with a need for systematic change, such as systems to recycle textile and nonwoven materials. It follows that a combined approach, involving both consumer demand and regulations, can be recommended as a most effective path forward. In addition, applications of artificial intelligence have potential to reconcile societal needs with future industrial practices.

  Lignin, a subject of extensive study in academies and industries, is known for its natural abundance, biodegradability, and potential to be transformed into biochemicals and biomaterials. However, the original biomass and extraction treatments, such as kraft pulping and the organosolv process, significantly influence its chemical structure, leading to variations in reactivity. Unfortunately, many scientific publications fail to provide comprehensive lignin property descriptions, which hampers experiment reproducibility and literature comparison. This, in turn, hinders fundamental studies and scientific advancements. This editorial aims to address this issue by advocating for including lignin characteristics in scientific papers when possible.

• Editorialpp 6979–6982Hubbe, M. A., and Madappa, K. (2024). "Contemporary papermaking in the tradition of Mahatma Gandhi," BioResources 19(4), 6979–6982.AbstractArticlePDF

  This editorial draws a parallel between important papermaking innovations that were implemented by Mahatma Gandhi and some more recent ventures in papermaking in India. Both of these examples share common themes of fostering the skills of local people, using local resources, and contributing to a better future. A key insight is the scaling of the equipment to be well matched with the size of the production team and enabling a broad range of product grades. The case study considered introduces a modern twist – using papermaking to achieve circularity in the production of textiles. As in the early days of European papermaking, once again waste textile products are serving as the primary source of material.

• Editorialpp 4040-4042Lan, K. (2024). “Some modeling challenges in dynamic life cycle assessment,” BioResources 19(3), 4040-4042.AbstractArticlePDF

  Life cycle assessment (LCA) has been a mainstream tool to evaluate the environmental impacts of products, services, and systems. Current LCAs inherently rely on the static basis and commonly fail to include temporal considerations. To better assist in the decision-making for sustainable development, dynamic LCA has been initiated to answer more complex and interdisciplinary questions. As in its initial phase, dynamic LCA faces many modeling challenges that at the same time are meaningful research opportunities. In modeling dynamic LCA, there are several key aspects that need more attention for contribution and close collaboration across the first three phases of the LCA framework.

  As a way to reduce microplastics or nano-plastics in the ocean, it is of interest to develop biodegradable paper-based drinking straws to replace  non-degradable plastic drinking straws. Primary questions to be addressed include how to design suitable coatings for paper drinking straws. Such coatings not only need to resist water. In addition, consumers have high expectations for the strength of a drinking straw. It is proposed here to replace non-biodegradable polypropylene, which is presently the main component of straws, with biodegradable and hydrophobic coating components via an entropy-driven approach. It is further proposed to develop colored paper-based drinking straws with cellulose nematic liquid crystal photonic pigments as a way to make the product stand out visibly, while at the same time mediating the usage of toxic chemical pigments.

  Kudzu (Pueraria lobata (Willd.) Ohwi) is a fast growing leguminous vine plant that has strong reproductive ability and low requirements on its growing conditions. It has been considered an invasive plant in some places because of its aggressive growth, which can destroy the habitat for native plants and animals. However, its strong environmental adaptability makes it easily cultivated as a sustainable resource. Kudzu can also keep soil from washing away and play an important role in ecological protection. Kudzu has had numerous practical uses in our daily lives since ancient times. For example, its root, stem, flower and pod are used in traditional Chinese medicine. Its root is a healthy food. And its leaf is used as fodder and forage for livestock. Moreover, some recent studies on kudzu have found that it is in rich of bioactive ingredients, especially isoflavones, which further broadens its uses in medicine, healthy food, and cosmetics industries. Its high starch and cellulose content makes it a promising feedstock for biofuel production and paper preparation. This editorial will give a brief discussion on kudzu and its comprehensive utilization.

• Editorialpp 4053-4055Hubbe, M. A. (2024). “Artists, papermakers, and the future,” BioResources 19(3), 4053-4055.AbstractArticlePDF

  This editorial considers three groups of individuals and how they often find themselves following common ways of thinking. Artists, especially those who become well known, are hard workers and somewhat stubborn. Once they have found a type of paper that works well for them, they tend to develop loyalty to it, regardless of what the label on the ream wrap may say. Papermakers, ancient and modern, likewise have tended to stick with practices that are convenient to them at the moment, whether or not they contribute to archival quality. Fortunately, the transition to alkaline papermaking practices means that modern printing papers tend to last a lot longer. Increasing knowledge of the importance of acid-free paper, as well as the principles of sustainability, are making positive contributions to our ongoing cultural heritage, at least to the part of that heritage that is related to cellulosic materials.

  Picking up a discarded can or bottle and placing it in a recycling bin may seem like a very small step to take in the direction of making a better world. The scope of benefits that might accrue, by combining many such steps, and making careful plans, was highlighted in a recent Waste to Advanced Resources Matter (WARM) workshop hosted at this university. As shown during the discussions at the workshop, those who are deeply involved with issues of waste management, climate change issues, and care for our planet already know the “broad brush” answers regarding what needs to be done. Now is the time for action in implementing efficient and widespread recovery of valuable materials and energy from what we presently throw away.
