What are the fire-retardant additives suitable for eucalyptus wood outdoor garbage bins?

Eucalyptus wood is a popular choice for outdoor garbage bins due to its durability and natural resistance to decay. However, like most wood types, it is combustible and requires fire-retardant treatments to enhance safety in outdoor environments. Suitable fire-retardant additives for eucalyptus wood include intumescent coatings, which expand when exposed to heat to form a protective char layer; boron-based compounds, such as borax and boric acid, that suppress flame spread and reduce smoke production; and phosphorus-containing additives, which promote char formation and inhibit combustion. These treatments can be applied through pressure impregnation, surface coatings, or dips, ensuring deep penetration and long-lasting protection. It is crucial to select non-toxic, weather-resistant formulations that withstand outdoor conditions like rain and UV exposure without compromising the wood's structural integrity or environmental friendliness. Regular maintenance and reapplication may be necessary to sustain fire-retardant efficacy over time.
