A study on synergies of combined pulp and fuel production

François Maréchal, Tuong-Van Nguyen, Erina Clare Mcdonald, Julia Granacher

To limit climate change by reducing global greenhouse gas emissions, a transition away from fossil fuels is required. Biofuels represent a promising low carbon alternative for sectors that are hard to electrify, such as aviation. The integration of bio ref ...

Guidelines for performing lignin-first biorefining

Jeremy Luterbacher, Feng Wang

The valorisation of the plant biopolymer lignin is now recognised as essential to enabling the economic viability of the lignocellulosic biorefining industry. In this context, the "lignin-first" biorefining approach, in which lignin valorisation is conside ...

Controlling lignin solubility and hydrogenolysis selectivity by acetal-mediated functionalization

Jeremy Luterbacher, Graham Reid Dick, Anastasiia Komarova

Existing lignocellulosic biomass fractionation processes produce lignin with random, interunit C-C bonds that inhibit its depolymerization and constrain its use. Here, we exploit the aldehyde stabilization of lignin to tailor its structure, functionality, ...

Techno-economic analysis and life cycle assessment of a biorefinery utilizing reductive catalytic fractionation

Jeremy Luterbacher

Reductive catalytic fractionation (RCF) is a promising approach to fractionate lignocellulose and convert lignin to a narrow product slate. To guide research towards commercialization, cost and sustainability must be considered. Here we report a techno-eco ...

Developing structure-oriented models for enzymatic hydrolysis of lignocellulosic biomass

Jessica Charlène Rohrbach

With the unsustainable use of fossil fuels increasing strains on human institutions and ecosystems, the development of a renewable energy alternative is of paramount importance. Second generation biorefineries, based on the production of fuels and chemical ...

Lignin Functionalization for the Production of Novel Materials

Jeremy Luterbacher, Stefania Bertella

Lignin, a major constituent of lignocellulosic biomass, is the largest natural source of aromatic molecules and thus is an attractive feedstock for renewable chemical production. Direct incorporation of isolated lignin into materials has long been research ...

Aldehyde-Assisted Lignocellulose Fractionation Provides Unique Lignin Oligomers for the Design of Tunable Polyurethane Bioresins

Jeremy Luterbacher, Raymond Gérard Buser, Florent Emmanuel Héroguel, Jean Thierry C Behaghel de Bueren, Chloé Wegmann

Thanks to chemical stabilization, aldehyde-assisted fractionation (AAF) of lignocellulosic biomass has recently emerged as a powerful tool for the production of largely uncondensed lignin. Depolymerization of AAF lignin via ether deavage provides aromatic ...

Aldehyde-Assisted Fractionation Enhances Lignin Valorization in Endocarp Waste Biomass

Jeremy Luterbacher, Raymond Gérard Buser, Florent Emmanuel Héroguel, Jean Thierry C Behaghel de Bueren, Chloé Wegmann, Graham Reid Dick

Endocarp biomass, which forms much of the inedible portion of nuts and stone fruits, is a promising feedstock for aromatic chemical production due to its high lignin content and because it is a food industry waste. Here, we tested the nut shells and fruit ...

Safety Decision-Making in Academia

Thierry Meyer, Anastasia Jung

This paper illustrates the challenges of safety management in Academia, which are difficult to overcome using conventional methods of risk management. The positive aspects and disadvantages of the risk management tools specifically designed for the laborat ...

Fractionation of lignocellulosic biomass to produce uncondensed aldehyde-stabilized lignin

Jeremy Luterbacher, Masoud Talebi Amiri, Ydna Marie Questell-Santiago, Graham Reid Dick

Lignin is one of the most promising sources of renewable aromatic hydrocarbons. Current methods for its extraction from lignocellulosic biomass—which include the kraft, sulfite, and organosolv processes—result in the rapid formation of carbon–carbon bonds, ...
