The chemical substances used in wood protection to prevent rot, mold, and marine pests often contain biocidal products whose levels are increasingly being regulated by authorities nationally and internationally. RISE experts can help customize wood protection options – both existing with less environmental impact as well as new options.
Many chemical substances that are currently used to provide wood protection against, for example, rot, mold, and marine pests are effective, but also toxic but regulated through the BPR (Biocid Product Regulation) at European level, and by the Swedish Chemicals Agency in Sweden. However, several of the biocides used today are likely to be restricted or banned in the near future.
RISE wood protection experts can help companies stay ahead by developing new alternative wood protection methods as well as modification of existing wood preservatives. Among other things, we can offer evaluation of wood protection options, its function, action mechanism, environmental impact through leaching studies, ecotoxicology, and life cycle assessment (LCA).
At RISE, we have knowledge of the mechanisms that in different ways break down wood. With the help of knowledge of the living conditions of the organisms that cause problems, we can develop alternative solutions to increase the durability of wood and thus an increased use of wood materials in society. Here are some concrete examples:
Today, creosote and copper-based wood preservatives are used in various applications. Through our understanding of fungi' degradation mechanisms, we can help develop alternative protection methods and impregnation fluids. We can also evaluate the function and effectiveness of these. We are accredited for testing in and above-ground according to the following standards: EN 252, EN 12037, EN 330. We also carry out laboratory tests according to EN 84, EN 113 and ENV 807.
Common substances used are organic fungicides such as IPBC and OIT. By changing the environment around the fungi, such as access to water and nutrition, the growth of mold can be prevented and thus the level of fungicides reduced. We offer laboratory testing in mold chambers and field testing.
Copper-based substances are used as protection against shipworms and drill grey sows. However, there are currently no approved wood preservatives for the marine environment (NTR Class M) in Scandinavia. We are developing new alternative wood covers that prevent that would meet the requirements. We have been testing wood in a marine environment for 20 years according to EN 275
Infestation of insects is an increasing problem in Sweden and the use of insecticides is severely limited. We help you find alternative solutions to protect wood materials.
Borates, polyphosphates and ammonium compounds are often used as additives in fire protection of wood. Some of these are phased out and leaching is a widespread problem in the outdoor environment. We can help you develop alternative methods for fire protection. There are various ways to change the conditions of the fire, such as reducing the supply of oxygen, fuel and heat.
