The first-ever bio-based cryogenic insulation is being developed in the Bio4Cryo project and upscaled in ESA funded BioSpace project. His scientific endeavours have resulted in 74 research papers indexed in Scopus and his Hirsh-index is 23.

Arnis Kokorevics, Scientific Secretary of the Latvian State Institute of Wood Chemistry, Latvia.
Arnis Kokorevics holds a Dr. chem. degree (1992). In his work at the Latvian State Institute of Wood Chemistry, he deals with organizational activities regarding research projects, including research evaluation and scientometrics. The range of his scientific interests includes the biorefinery concept, scaling and fractal geometry approaches to description of the structure of wood and its components.

Kristīne Meile, Researcher of the Biorefinery Laboratory and Head of the Liquid Chromatography Centre at the Latvian State Institute of Wood Chemistry, Latvia.
Kristīne Meile holds a Dr. chem. degree from the University of Latvia, Faculty of Chemistry. She applies her analytical background to separate, purify, characterize and valorize chemical products obtained from wood and other lignocellulosic feedstocks to develop new biorefinery possibilities. She is captivated by the biorefinery concept and always tries to tie up loose ends and approach zero-waste systems. Apart from her research work, Dr. Meile is the organizer of the BTechPro! conferences.


Summary

Biomass, as the only carbon containing renewable resource, is a key to future materials, fuels and chemicals. For a higher beneficial impact biomass is processed within biorefineries to obtain several valuable products from a single feedstock. This special issue is dedicated to current and innovative technologies used for obtaining biomass-based products, and how these technologies can be combined for maximum efficiency. Topics of interest include, but are not limited to:

· Biomass feedstock pre-treatment

· Biomass processing and extraction

· Biomass-based materials

· Bioengineering technologies

· Synthesis of bio-based chemicals and polymers

· Characterisation of biorefinery products

· Bioeconomy and environmental aspects

    Abstract Birch outer bark (BOB) from Betula pendula Roth. is a unique and valuable biomass feedstock that contains suberin. The biopolyester suberin is built from bifunctional fatty acids-suberinic acids (SA)-which can be obtained through a depolymerization process in an alkaline medium and used as a binder due to their adhesive properties. The aim of this study was to develop the SA-containing binder and identify suitable pressing conditions to produce plywood that meets the shear strength requirements of the EN 314-2 standard 3rd moisture resistance class for bonding quality, ensuring durability in unprotected exterior conditions (shear strength ≥… More >

    Abstract Fast pyrolysis of pre-treated birch wood in a super-heated steam environment produces a condensate rich in anhydrosugars. With the objective to obtain several product streams from this condensate, the possibility of extracting additional chemical species is explored, thus promoting the development of a pyrolysis-based biorefinery. In this work, the extraction and recovery of pyrolytic phenols from birch wood pyrolysis condensate was studied using ion exchange resins. With an aim to achieve effective phenol recovery, while obtaining high purity levoglucosan, basic ion exchange resins, both in OH and Cl form, as well as polystyrene-divinyl resins without functional… More >

    Evaluating the Potential of Birch Bark Suberinic Acids for Solid Wood Impregnation

    Abstract Instead of the traditional linear model of taking, making, and disposing, the circular bio-economy promotes a regenerative approach. Although there is potential to create valuable products like betulin, lupeol, and suberinic acids (SA) from outer birch bark, many industries, such as plywood and pulp, often choose to incinerate substantial amounts of leftover birch bark to meet their energy needs. This highlights the importance of obtaining valuable products from wood. The objective of this study was to examine various fractions of SA and assess their potential for wood impregnation. The fractions included SA potassium salts in… More >
