Notes to Editors:

Accsys Technologies PLC(www.accsysplc.com) is an environmental science and technology company whose primary focus is on the production of Accoya® wood and technology licensing via its 100% owned subsidiary, Titan Wood Limited, which has manufacturing operations in Arnhem, the Netherlands, a European office in London and an American office in Dallas, Texas. Accsys Technologies PLC is listed on the London Stock Exchange AIM market, and on Euronext Amsterdam by NYSE Euronext, under the symbols 'AXS'. Accsys' operations comprise three principal business units: (i) the Accoya® wood production facility; (ii) technology development, focused on a programme of continuous improvements to the process engineering and operating protocols for the acetylation of wood which are currently under development and the development of technology for the acetylation of wood elements; and (iii) the licensing of technology for the production of Accoya® wood and Tricoya® wood elements across the globe.

Wood Acetylation is a process which increases the amount of 'acetyl' molecules in wood, thereby changing its physical properties. The process protects wood from rot by making it "inedible" to most micro-organisms and fungi, without - unlike conventional treatments - making it toxic. It also greatly reduces the wood's tendency to swell and shrink, making it less prone to cracking and ensuring that, when painted, it requires dramatically reduced maintenance.

Accoya® wood (www.accoya.com) is produced using a process, the subject of patent applications around the world, that effectively converts sustainably grown softwoods and non-durable hardwoods into what is best described as a "high technology wood". Distinguished by its durability, dimensional stability and, perhaps most importantly of all, its reliability (in terms of consistency of both supply and quality), Accoya® wood is particularly suited to exterior applications where performance and appearance are valued. Unlike most tropical and European hardwoods, its colour does not degrade when exposed to ultraviolet light. Moreover, the Accoya® wood production process does not compromise the wood's strength or machinability. The combination of UV resistance, dimensional stability, durability and retained strength means that Accoya® wood offers a wealth of new opportunities to architects, designers and specifiers. For marine uses where weight is also important, Accoya® wood for the first time provides boat builders with a wood that is strong, lightweight, durable and retains its natural beauty for far longer.

Tricoya® wood Elements (www.tricoya.com) is Titan Wood's proprietary technology for the acetylation of wood chips, and particles for use in the fabrication of wood based composites, including panel products. These composites demonstrate enhanced durability and dimensional stability which allow them to be used in a variety of applications that were once limited to solid wood or man-made products. Tricoya® Wood Elements is lauded as the first major innovation in the wood composites industry in more than 30 years.
