A pioneering process developed by a Norwegian hardwood alternative is converting softwoods into hardwoods as a viable green alternative for endangered species.
Norwegian wood technology company Kebony has won plaudits for its sustainable alternative to tropical hardwood, including the recent Best Innovation accolade at the Best Business Awards 2014, which honours organisations that have identified a requirement for an innovative green-tech product and successfully brought it to market.
Kebony is a sustainable and aesthetically pleasing alternative to popular hardwoods from tropical regions, made all the more relevant and important as deforestation becomes an ever-more pressing concern, such woods deplete, and corporations and consumers look for a sustainable and acceptable alternative.
Kebony CEO Christian Jebsen notes the importance of products like that manufactured by his company in a world where annual forest destruction releases 20 percent of global CO2 emissions and a third of global rainforests have disappeared over the last 50 years.
“Kebony offers a solution to this global issue,” he claims, adding that the product has a carbon footprint of less than 10 percent compared with Burmese teak and other similar wood that it aims to substitute for.
Kebony is based on the company’s developed process, appropriately termed Kebonisation, where sustainable softwoods are, simply put, converted into hardwoods. It is a process which makes such woods more durable, harder and stable using a liquid by-product from farmed sugar cane production liquids.
Applicable to many types of wood, Kebonisation changes the cell structure of non-durable woods through a non-toxic process of impregnation and heat, which alters the wood fibers’ ability to hold moisture.
The process improves the dimensional stability at moisture variations substantially from the parent wood by 50 percent, making it more resistant to shrinking or swelling, and therefore to weather, wear and decay.
During production at the company’s production plant, which opened in 2009, pressure and heat are applied to the original woods to a degree that their lifecycle is increased seven to nine-fold.
The furfurylation process gives the wood a darker colour which makes Kebony woods resemble Teak, Ipé, Mahogany and other tropical varieties of wood, making it more than just a viable practical alternative to such woods, but also a visually appropriate one. The products are dark, and acquire a silver grey patina over time if left untreated.
Kebony products are suitable for a multitude of applications and designs, encompassing both indoor and outdoor applications, and have been used in a variety of striking projects in many locations.
In terms of cost, initial outlay for Kebony is a little above that of toxin-treated timber, however the creators claim it will last approximately three times as long, and, not requiring maintenance, its lifecycle cost will be about half compared to buying and maintaining treated or impregnated timber, making it a good-value long-term investment.
Tropical timber, such as teak, mahogany and other endangered wood species will therefore in most cases cost more than Kebony.
The growing company recently expanded its sales and distribution operations into the US market via a new distribution partner.
