EcoFriendly Wood Treatment Options

Aug 03, 2023Richard Weager

Mankind has used wood, a natural and versatile material, for centuries. From the construction of homes and furniture to the creation of tools and art, wood has been an integral part of human development. However, despite its durability and versatility, wood is susceptible to the elements and various organisms. Over time, untreated wood can deteriorate, losing its strength and aesthetic appeal. To combat this, treatments have been developed to protect and preserve wood, extending its lifespan and maintaining its natural beauty.

Unfortunately, many traditional wood treatments contain harmful chemicals that can have a detrimental impact on the environment and human health. As our understanding of these impacts grows, so does our desire for safer, more sustainable alternatives. This article delves into the world of eco-friendly wood treatment options, exploring their benefits, how they compare to traditional methods, and why they are an essential consideration for anyone working with wood.

The Basics of Wood Preservation

Wood, while sturdy and durable, is not impervious to the ravages of time and the elements. Weather, particularly rainwater, can seep into the wood fibres, causing damage that can weaken the wood and eventually necessitate replacement. Microorganisms and insects, such as mould, fungi, and wood-boring insects, can also cause rot and decay, further reducing the lifespan of the wood.

To combat these issues, wood is often treated with a preservative or sealed, much like a wood stain. These treatments work by creating a protective barrier on the wood’s surface, shielding it from water, organisms, and other potential sources of damage. Sealing the wood involves applying a protective layer to the exterior, while staining involves adding colour to the wood, often alongside a protective layer. Both methods aim to extend the lifespan of the wood, preserving its strength and appearance for longer.

The Problems with Traditional Wood Sealers

Traditional wood sealers, while effective, often contain toxic substances that can be harmful to both the environment and human health. For example, creosote, a popular wood sealant made from coal tar, was found to be carcinogenic and has been banned for public use in Great Britain since 2003. Other ingredients, such as arsenic, can also have serious health implications.

These toxic substances can leach out of the wood over time, contaminating the surrounding soil and water. This can harm local wildlife and plant life and even pose a risk to humans if the contaminated soil or water is ingested or comes into contact with the skin. Furthermore, the production of these sealers often involves processes that contribute to air pollution and climate change, adding to their environmental impact.

The Benefits of Natural Wood Preservatives

Natural wood preservatives offer a more environmentally friendly alternative to traditional wood sealers. These treatments use bio-based organic materials and are safe for children, humans, plants, and wildlife. They contain no harmful chemicals or heavy metal compounds and have low or zero VOC (Volatile Organic Compounds).

Furthermore, wood treated with natural preservatives can be recycled once it is no longer needed, reducing waste and contributing to a more sustainable future. This is a significant advantage over wood treated with traditional sealers, which often cannot be recycled due to the toxic chemicals they contain.


In our quest for sustainability and environmental preservation, the shift towards eco-friendly wood treatment options is not just a trend but a necessity. Traditional wood sealers, while effective, often come with a host of environmental and health concerns. The toxic substances they contain can leach into the environment, causing harm to both wildlife and humans.

Eco-friendly alternatives offer a safer, more sustainable solution. These treatments are non-toxic, safe for humans and wildlife, and can even enhance the natural beauty of the wood over time. Furthermore, wood treated with these products can be recycled, reducing waste and contributing to a more sustainable future.

As we continue to strive for a greener planet, the adoption of eco-friendly wood treatment options is a step in the right direction. Whether you’re a professional carpenter or a DIY enthusiast, choosing these treatments can help you contribute to a healthier, more sustainable world.
