Notes to editors:

Accsys Technologies PLC (www.accsysplc.com) is a chemical technology group whose primary focus is on the production of Accoya^® wood and technology licensing via its subsidiary, Titan Wood Limited, which has manufacturing operations in Arnhem, the Netherlands (through its subsidiary Titan Wood B.V.), a European office in London, United Kingdom, an American office in Dallas, Texas (via its subsidiary Titan Wood, Inc) and technology licencing associated with the acetylation of wood elements via its subsidiary Tricoya Technologies Limited.  Any references in this announcement to agreements with Accsys shall mean agreements with either Accsys or its subsidiary entities unless otherwise specified.  Accsys Technologies PLC is listed on the London Stock Exchange AIM market and on Euronext Amsterdam, under the symbols 'AXS'. Accsys' operations comprise three principal business units: (i) Accoya^® wood production; (ii) technology development, focused on a programme of continuous development of and improvements to the process engineering and operating protocols for the acetylation of solid wood 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.

Accoya^® Wood (www.accoya.com) is produced using Accsys' proprietary patented acetylation technology 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. Moreover, the Accoya^® wood production process does not compromise the wood's strength or machinability. The combination of dimensional stability, durability and retained strength means that Accoya^® wood offers a wealth of new opportunities to architects, designers and specifiers. These benefits result in lower maintenance and total cost of ownership while using a higher sustainable and environmental responsible building material.

Tricoya^® Wood Elements (www.tricoya.com) are produced using Accsys' proprietary technology for the acetylation of wood chips, and particles for use in the fabrication of panel products such as medium density fibreboard and particle-board. These products 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. Exploitation of Accsys' proprietary technology relating to Tricoya^® Wood Elements is carried out through Tricoya Technologies Limited.  Tricoya^® Wood Elements are lauded as the first major innovation in the wood composites industry in more than 30 years.

Wood Acetylation is a process which increases the amount of 'acetyl' molecules in wood, thereby changing its physical properties. When carried out to a sufficient level throughout the wood, this 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.
