Putting spice into wood protection
To overcome the leaching issue, scientists are now evaluating ways to impregnate natural preservatives into wood using agents that can cross-link these metabolites to wood fibres. Scion has screened almost 100 natural compounds in their search for naturally occurring preservatives.
The compounds tested have been sourced from medicinal and native plants, essential oils, agricultural/horticultural wastes, as well as secondary metabolites from bacteria and fungi.
