The only sustainable alternative to tropical hardwood

Furfuryl alcohol, which is made from bio-renewable furfural, is the main ingredient used for wood-modification processes like 'kebonisation', which convert softwoods in looks and properties that are similar to tropical hardwood. Originally designed to replace the toxic CCA process, furfurylation of wood offers non-toxic woods for playgrounds, floors, cladding, etc.

from Kebony.com: Developed in Norway, the Kebony technology is an environmentally friendly patented process, which enhances the properties of non-durable softwoods with a bio-based liquid.

As a result the wood’s cell structure is permanently modified adopting premium characteristics. Kebony is a highly durable, sustainable wood ..

.. with the aesthetics and performance of the best tropical hardwood, which requires minimum maintenance and brings low life cycle costs. Suitable for internal and external applications that demand high performance and great aesthetics, Kebony is available in clear and character grade pines. All Kebony woods acquire a silver patina after exposure to the elements.

Recognized as Technology Pioneer 2014 by the World Economic Forum and Global Cleantech Tech 100, Kebony has been embraced by leading architects and developers internationally, served through a global sales and distribution network.

Overcoming the disadvantage of urea-formaldehyde treated wood

Furfural and urea react in an acid catalysed medium. The aldehyde group of furfural undergoes condensation with two urea and link the two urea substrate with the release of a water molecule to form a pure white furfural-urea resin (FUR).

A group of Indian scientists have developed an efficient synthesis of of untainted, superior furfural urea resin (FUR) [1]. Urea, a carbamide, is common organic chemical with versatile characteristics. It forms resins with aldehydes, most commonly formaldehyde, to produce urea-formaldehyde (UF) resins, which is used as a wood adhesive for many years, and is still the most widely used interior plywood and particleboard adhesive.

Urea is an attractive chemical for wood improvement because of its non-toxicity, cheapness and ease of use. However, formaldehyde-urea resins emit formaldehyde. Plywood interior furniture, or kitchen cupboards made from particle boards release formaldehyde, indoors! Formaldehyde is classified by the WHO as a known human carcinogen [2].

In order to reduce indoor formaldehyde levels, inferior glues with less formaldehyde have been used, since the 1980s, whilst research continued to find suitable alternatives.

The reaction of furfural and urea has been researched in the early 20th century. Until now, there were too many draw-backs to make it a viable process. This new synthesis, using a (natural!) zeolite catalyst, has eliminated them.

The new process claims the following:

Reduced reaction time.

Enhanced product quality.

The process is benign, environ friendly, efficient and extremely fast.

The natural zeolite catalyst can be recycled and reused, several times.

Natural Fibres + Poly(Furfurly Alcohol)= Light weight structural panels

Poly(Furfuryl Alcohol), PFA, is obtained from a condensation polymerisation of furfuryl alcohol (FA). FA is made from furfural , which is manufactured from a variety of biomass.image Generic structure of PFA

Biomass-based furan resins are mainly known in the foundry industry. In addition, user-friendly furan resin systems have been developed for variety of composite applications [1]. Besides the use in the automotive industry, PFA composites have a high thermal stability and could also be used in interior of aircraft cabins, internal fittings for buildings, rail carriages or in the built environment [2].

Some fibre-reinforced PFA options:

Cellulosic fibre, e.g.: flax, hemp, sisal, bagasse or wood

Non-woven cellulose fibres

Carbon fibres or glass fibres

Mineral or graphite filler for use as a cementing binder for chemical resistant polymer concrete.

Eco-friendly thermo-stable bioresin:

PFA blended with lignin increases the biocomposite resin's strength[3]

Efficient Solid Acid Catalyst for the Production of Furfurals

Self-assembled nanoparticulates of porous sulfonated carbonaceous TiO2 material that contain Brønsted and Lewis acidic sites were prepared by a one-pot synthesis method. The carbonaceous heterogeneous catalyst (Glu-TsOH-Ti) with a Brønsted-to-Lewis acid density ratio of 1.2 and more accessible acid sites was effective to produce 5-hydroxymethylfurfural and furfural from biomass-derived mono- and disaccharides and xylose in a biphasic solvent that comprised water and biorenewable methyltetrahydrofuran….

DalinYebo‘s insight:

HMF can be converted to 2,5-dimethylfuran (DMF), which is a liquid biofuel with a greater energy content bioethanol. Oxidation of HMF gives 2,5-furandicarboxylic acid, which has been proposed as a replacement for terephthalic acid in the production of polyesters. It can also be converted to gamma-valerolactone, 2,5-furandicarboxylic acid or 2,5-bis(hydroxymethyl)furan. (wikipedia.org).

Molybdenum Carbide: Deoxygenation Catalyst for Converting Furfural to 2-Methylfuran

Selectively cleaving the CO bond outside the furan ring of furfural is crucial for converting this important biomass-derived molecule to value-added fuels such as 2-methylfuran. In this work, a combination of density functional theory (DFT) calculations, surface science studies, and reactor evaluation identified molybdenum carbide (Mo2C) as a highly selective deoxygenation catalyst for converting furfural to 2-methylfuran. ..

DalinYebo‘s insight:

2-Methylfuran is a flammable, water-insoluble liquid with a chocolate odor, found naturally in Myrtle and Dutch Lavender used as a FEMA GRAS flavoring substance, with the potential for use in alternative fuels (wikipedia.org).

It is also used as a basis for the synthesis of many pharmaceutical, agricultural and industrial chemicals (dalinyebo.com/platformchemical)
