TANASOTE – KEEPING WOOD AS THE SUSTAINABLE CHOICE

If the timber industry is to keep wood as a primary material of choice in these important high risk applications, it needs to be bold and adopt modern, innovative BPR approved alternatives that will deliver high performance and sustainability.

TANASOTE is an alternative that will meet this criteria. TANASOTE is a high performance preservative system from the experienced development team at Lonza Wood Protection, designed to meet the future needs of the
high performance timber sector with attributes that will suit the agricultural, utility pole and railway sleepers industries whilst meeting the stringent risk assessments of the Biocidal Products Regulations (BPR).

Andy Hodge, Lonza’s Marketing Director explains the product development and its latest progress to market. ‘TANASOTE is now a real alternative for our customers involved in the supply of heavy duty timbers, such as utility poles, railway sleepers, and increasingly as an option for the protection of fencing, revetments and landscaping materials.’

‘In developing the product we first went out to the industry to assess their needs for a modern alternative to Creosote. The response was that it must be performance led, delivering a minimum 40 year service life for poles in particular. It must have a longevity using modern, authorised actives as well as a strong life cycle analysis to compete with alternative materials. The product must have a mobility that works within existing treatment facilities. And finally it must have key ancillary properties relating to the treated timber markets – non corrosive to metal fixings and both low conductivity and good climb-ability properties for communication poles.’

‘TANASOTE has been developed as a hot copper oil technology with a powerful co- biocide to protect against a wide spectrum of aggressive copper tolerant decay organisms. It has an excellent industry fit because it can be used in existing or new Creosote type plants. We are looking at a minimum 40 year service life for poles and 30 years for railway sleepers.

Excellent Life Cycle Analysis (LCA)

3 independent life cycle studies have been conducted with excellent resulting credentials across the board for TANASOTE compared to competing materials such as steel,concrete and fibre glass. And all
the ancillary properties such as conductivity and corrosivity for metal fixings highlighted by our markets sectors are all similar to Creosote treated timbers and better than water based preservative treated timbers.’

‘We have been working proactively with interested stakeholders undertaking trial optimised treatments both in our dedicated pilot plant facility based at our Research and Development facilities in Castleford and now on a commercial scale for test purposes with a partner treatment company in Belgium. The results are extremely encouraging across a range of timber species and different components.’

‘TANASOTE developments are at an advanced stage and we have gained a wide range of data from our optimising work. The consistent results we are seeing are providing a great deal of confidence that we will meet the long term protection requirements expected.’

‘TANASOTE is currently continuing through its authorisation process within the Biocidal Products Regulation and we are extremely optimistic on the outcome. We are then looking to move forward with a commercial launch in the early part of 2020.’

‘We are ready to talk further with key stakeholders. Any interested parties who wish to discuss their particular requirements for TANASOTE should feel free to contact us. We will be delighted to explore how we can work together to build these into our testing and assessment trials.’

Lonza recently held a webinar to introduce TANASOTE to European markets and had a very positive response. Anyone wishing to view the recorded event can do so by visiting the following web link – https://youtu.be/G9Rluw9LtCo
