2.9 Linkage Sequences in Lignin Populations (LILIPOPS): A glimpse into lignin heterogeneity
Despite several decades of analytical investigations, the elucidation of the complete molecular structure of lignin remains a challenge. State of the art analytical techniques such as advanced NMR techniques have been useful tools to propose global structural motifs based on inter-unit linkage but still lack the proficiency to discerning structural populations with complete linkage sequences. […]
3.6 Betulin epoxide polymer for coatings
The growing demand for sustainable alternatives to petrochemical-based epoxy resins has led to the development of bio-based systems. This study introduces a new synthesis method using betulin from birch bark to produce high-value polymeric resins. A novel betulin-derived epoxide (BOE) was synthesized and combined with epoxidized rapeseed oil (ERO), then thermally cured with seven anhydrides […]
2.10 Lignin-based catalysts for catalyzing CO2 cycloaddition to epoxides
Cyclic carbonates have received considerable attention from academy and industry because of their applications as polar aprotic solvents, non-ionic surfactants, electrolytes in Li-ion batteries and precursors for chemical syntheses. These compounds can be synthesized through cycloaddition reaction of CO2 to epoxides in mild conditions, which is a sustainable strategy contributing to carbon neutrality. Lignin and melanin, […]
11.5 Printed circuit board substrates derived from lignocellulose nanofibrils
The growing problem of electronic waste poses an environmental challenge due to petroleum-based materials and toxic metals. Recycling e-waste is complex and costly due to numerous components requiring separation. Using bio-based, biodegradable materials for printed circuit board (PCB) substrates simplifies PCB component separation and improves environmental impact [1]. Hornified cellulose fibrils are promising PCB substrates […]
11.4 Printed electronics directly on wood veneers
Sustainability is becoming an increasingly crucial focus across various industries, reigniting interest in wood as a material. The major objective of this project is to pave the way for the transition of wood from a conventionally utilized resource to a highly functional and, at the same time, aesthetic material. From this transformation, wood will emerge […]
3.3 Development of biobased terpenoid-acrylic copolymers incorporating lignin-based UV blockers for wood protection
One of the main resources for renewable materials has been wood waste. In this sense, terpenes, which are extracted from coniferous trees as well as citrus fruits, are an exploitable category of biomass.The objective of this study is to develop innovative wood coatings using renewable bio-based polyacrylates from terpenoids, a subclass of terpenes used on […]
2.11 Advanced aromatic platforms from lignocellulose for high-value materials production
Keywords: lignin, Depolymerization, heterogeneous catalystLignin is the largest natural source of aromatic compounds which, and it plays a crucial role in advancing sustainable chemistry by reducing dependence on fossil resources. The ongoing study investigates the catalytic reductive depolymerization of lignin originating from various industrial sources, aiming to produce fractions tailored for high-value applications such as adhesives, polymer chemistry, […]
11.6 Fabrication of Lignosulfonate-Based Supercapacitor Electrodes through Self-Activation and Two-Step CO₂ Activation with Plasma Treatment
In this study, we aim to promote the valorization of technical lignin derived from the pulp and paper industry and develop sustainable and environmentally friendly energy storage devices. Lignosulfonate was used as a precursor, and two different approaches were employed: self-activation and two-stage CO2 physical activation, producing porous carbon (PC) and lignosulfonate-activated carbon (LSAC), respectively. […]
2.Invited A novel class of bio-surfactants via alkali-O2 oxidation of hard wood hydrolysis lignin
Surfactants are a class of amphiphilic compounds which are essential in various industrial applications, as they can aid in the formation of emulsions, dispersion or act as wetting agents.(1) Despite their wide use, only less than 5% of the current surfactant market share consists of compounds entirely derived from plant wastes and renewable carbon. Lignin, […]
3.4 Suberin-based aqueous dispersions for barrier packaging applications
Barriers and coatings are commonly used as protective layers of consumables such as food and liquid packages1,2, however, currently harnessed conventional barrier layers are predominantly made from fossil-based polymers, with increasing global consumption causing concerns related to climate change. Therefore, bio-based barriers and coatings are urgently needed to reduce greenhouse gas emissions and our dependency […]
