Upscaling Bioblock production
The construction sector produces large amounts of waste and relies heavily on non-renewable materials. Currently, MDF waste is barely recycled and poses problems in the waste wood fraction. It is …
Reducing the set recovery of compressed wood through pre-treatment with a water-based solution of citric acid and sorbitol
The positive relationship between wood density and mechanical properties drives interest in compression techniques. A significant challenge in this practice is the tendency of compressed wood to revert to its …
Development and Characterization of Bioblocks: A Sustainable Wood-Based Composite Utilizing MDF Residues, Citric Acid and Polyols
The increasing production of Medium-Density Fiberboard (MDF) in recent years highlights its importance in the wood-based materials industry. However, recycling MDF remains challenging, with only scarce industrial applications [EcoReFibre, 2024; …
A novel method of wood modification by citric acid and sorbitol
Long durability of products in exterior use is essential for several applications including wooden materials, and where wood can be used as a substitute for other alternatives. Due to public …
Moisture relations in wood modified with sorbitol and citric acid
Susceptibility of wood to fungal degradation shortens service life and is one of the primary factors limiting the use of wood in constructions today. Traditionally, biodegradation has been mitigated by …
Advances in polyesterification of wood using sorbitol and citric acid under aqueous conditions
The utilization of biocides to prevent biological degradation of wood in outdoor situations is facing increased challenges. Environmentally motivated legislation is restricting the use of biocides and thus incentivizing the …
Investigation of oil curing as an alternative curing procedure for Scots pine modified with sorbitol and citric acid
Modifying wood with sugar alcohols and polycarboxylic acids, in particular with a combination of sorbitol and citric acid (SorCA), is a promising bio-based alternative to crude oil-based modification systems (Larnoy …
Imidazole-based wood modification
To fulfil the increasing need of durable wooden materials in the construction sector novel wood modification techniques are required (Sandberg et al. 2021). Wood modification utilising chemicals and thermal treatment …
Advances in CIOL-protected Wood – the Road Towards Commercialization
Most commercial wood from the northern European region are of low natural durability. Products from these wood species for outside applications need therefore protection to increase service life. This protection …
The effect of citric acid and sorbitol on the swelling and sorption behaviour of wood
Recently, research activities regarding a chemical modification technology, which uses citric acid (CA) andsorbitol, have been initiated. Both, CA and sorbitol (SorCA), originate from renewable resources and arecommonly used in …
Initial Quality Control Trials of Sorbitol and Citric Acid (SorCA) Modified Wood
Overall, spectroscopic techniques can be suggested as screening methods for distribution of impregnation chemicals of esterified wood. The results show that using spectroscopic methods such as ATR-FTIR, NIR and X-ray …
Comparative study on the suitability of different solutions based on sorbitol and citric acid as wood adhesives
Adhesives used in the wood processing industry are today still based almost exclusively on petroleum. A potential bio-based adhesive could be the combination of citric acid (CA) and sorbitol (SCA). …
Quality control of esterified wood using hyperspectral imaging
This study tested the suitability of hyperspectral imaging techniques to visualize the distribution of polyester in softand hardwood species on the cellular (confocal Raman imaging) and on the macrostructural level …
