Roundwood Solutions

Our company Roundwood Solutions has been the largest producer of timber fence post material in Australia for a number of years. We produce up to 60,000m3 per year with all our timber coming from plantation pine forests from our local area which was planted generations ago, specifically for jobs into the future.

We decided 3 years ago to value add our own timber, build our company brand and invest in our own treatment plant. Additionally, this uncovered a point of difference to the traditional current applications in the market that were not environmentally friendly. Through partaking in this process, we uncovered a new product, which is now trademarked as Tanapost®. We are an example to all organisations within the industry, bringing superior ecological solutions to our agricultural sector.

“Through partnering with Climate Active to be certified carbon neutral, Tanapost® could be a huge advantage to others in the agricultural sector who aspire to lower their carbon footprint to achieve carbon neutrality.”

Type of certification


Tanapost ® is a water based Creosote product and is the best agricultural product development we have seen throughout 40 years in the timber industry. When considering the millions of fence posts and vineyard trellising in Australia, it was noted that other wood treatments have no end of life solution and carry toxic air borne effects on our communities including bushfires, soil degradation and health and safety issues from initial handling. The benefits of Tanapost® include its dry to touch texture, contains no heavy metals, there is no residue that burns to the skin from handling the product, there is little to no leaching, lack of noxious odour which alleviates headaches, sinus irritation and breathing implications and is inherently fire retarding which implies once the fire front has gone past, the post will self-extinguish. We promise to our customers that we take back our product at its end of life and put it back through our wood gasifier to burn. This extracts the heat and drives our steamer which dries our timber in the first place. This is so our timber can be treated with our carbon based wood preservative we call Tanapost®. In our gasifier, the residue from the process is Biochar, which has the ability to store carbon and reduce greenhouse gas emissions. 

How long have you been certified carbon neutral?

Since September 2021.

Why did you choose to go carbon neutral?
