International Research Group on Wood Protection

OUR Purpose

To provide a forum for communication of the science and technology associated with wood protection.

Welcome to the website of the International Research Group on Wood Protection, commonly known as the IRG.

The IRG membership is a structured group of like-minded scientists and technologists focused on generating knowledge of the science of wood deterioration, and novel solutions to provide sustainably and environmentally responsible products for the protection of wood-based materials.

The primary function of the IRG is to provide opportunities for the exchange of ideas and information in an informal atmosphere, unencumbered by refereeing of papers or other pre-conditions. The primary vehicle is the annual meeting usually held in May of each year with global locations chosen as providing optimal opportunities for interactions between attendees and in settings that are both interesting and economically viable for our diverse attendance from around the world.

Each year 100 to 190 papers are presented and published, with all papers being available free to members and sponsors in electronic format through our searchable database. Since our inception in 1969 nearly 5,000 IRG papers have been published and all are available online or through the IRG Compendium. Non-members of the IRG are able to search the online database and purchase any paper for download through the website.

Membership and sponsorship is open to all interested persons and organizations.The executive direction of the activities of the IRG is carried out through a number of committees made up of members and sponsors representatives. The IRG Secretariat is based in Stockholm, Sweden.




IRG52 in Japan

IRG52 will be held during May 9-13, 2021 in Numazu City, Japan. The two previous IRG conference in Japan were IRG22 in 1991 in Kyoto, and IRG32 in 2001 in Nara, both of which were World Heritage cities.

Why is this meeting in Numazu?

The answer is Mt. Fuji, the highest peak in Japan (3776m), which symbolizes Japan, has been registered as a UNESCO World Heritage Site, named "Mt. Fuji-the faith mount and the source of art". Numazu city is blessed with natural beauty, including a breathtaking view of Mt. Fuji rising majestically over Suruga Bay. In addition, you can enjoy the Numazu fishing port, shops and restaurants, and the holy land of Anime.

Viewing highlights in the region around Numazu that you will visit include the Fuji Sengen shrine, the Fuji World Heritage Museum, Shiraito (thousands of streams) falls, the paved mountain road up towards Mt Fuji, and the Gotenba Restaurant and Brewery with all-you-can-eat & drink buffet.
