Preserving the wood protects it from fungi, decay and termites and extends the service life of wood for 20 to 40 years in the case of outdoor decks and walkways, and even 50 and 60 years, in the case of wood utility poles. Preserved wood from such building projects may, in time, be reused as fence posts or as components for making outdoor lawn furniture or pet houses. Some preserved wood products, like creosote pressure-treated railroad crossties, may see a recycled second life as landscape and garden border timbers or as retaining walls. Those same crossties may then be used again and burned at approved co-generation facilities as fuel to create energy. Since all of us are concerned about the environment, it's reassuring to know that using wood products like preserved wood has environmental benefits.
Wood is a natural product that is renewable, reusable and recyclable.
Using preserved wood is good for the environment.
