Towards Adhesive-Free Timber Buildings (AFTB)
Adhesive-Free Timber Buildings addresses the wasteful and harmful use of toxic adhesives in the manufacturing of Engineered Wood Products (EWPs) by the construction industry.
Providing confidence in the structural properties of adhesive-free EWPs, using compressed wood is the key to this market uptake.
University, industry and the public sector will co-operate to demonstrate new adhesive-free EWPs using new technology, encouraging and enabling market uptake across North West Europe (NWE).
The project will move the Technology Readiness Level (TRL) from 4 to 7.
More than 5 million m3 of EWPs were produced in the EU in 2013/14 and the market is growing, as EWPs provide a "green" alternative to steel and concrete in construction. In the long-term, the project aims to result in the production of 1 million m3 of adhesive free products and remove 6000 tonnes of the toxic adhesives currently used in manufacturing. The adhesive-free products will be 100% reusable and recyclable. This will have a positive impact in North West Europe where the majority of EWPs go to landfill or incineration contributing to the 15 million tonnes of timber construction waste in landfill across Europe each year. In the long term, the project aims to result in the reduction of EWPs to landfill by 0.5 million tonnes at end of life.
Adhesive-Free Timber Buildings will support ten NWE businesses to adopt the new technology and produce a range of adhesive free EWPs. This will have additional benefits leading to competitive advantage, economic growth and sustainable jobs. The new technology will also contribute to the sustainable management of forests in NWE and connected rural livelihoods by adding value to locally available low-quality timber.
The advocacy, influencing and business support activity undertaken in the Long-Term Effects work package will sustain these positive impacts after the project has ended.

AFTB consortium member Luxembourg University of Science and Technology (LIST) is holding a tendering exercise to commission a report on the constraints and opportunities presented by the scaling up of all-timber construction techniques. Details specification and selection criteria are listed below. The guide budget for the exercise is ca. €10,000 ex VAT, though all submissions will be considered. Payment will be following acceptance of the final report, which is required to be completed by October 1st 2019.
This work is funded by the towards Adhesive-Free Timber Buildings Project, through ERDF programme Interreg North-West Europe.
The report should cover:
A detailed overview of existing all-timber construction methods, defined as those timber methods which do not principally rely on adhesive, and to a lesser extent metal fixings.
These would include Brettstapel and dowel-laminated timber (DLT) panels. Covering:
- Craft-person effort
- Lead times
- Process scheduling
- Environmental impact
- Future recyclability/reusability
- Planning, regulatory issues
• An analysis of the additional costs, complications and benefits of this approach as compared to glulam/CLT construction.
• An analysis of the costs, difficulties and potential market opportunities of incorporating:
- All-timber, semi-ductile connections including highly densified timber plates (laboratory scale data, including on production methods, to be provided by the AFTB project).
- Highly densified timber dowels in dowel laminated beams and panels (laboratory scale data, including on production methods, to be provided by the AFTB project).
The final analysis should also be presented via the framework of a hypothetical construction operation in the North-West European area with a production rate of fifty two or more storey dwellings per year. The intended audience are academics, timber-industry and related professionals, who are expected to have a good knowledge of basic concepts in timber engineering and construction.
The report should be in English and be formatted to a high level such that it can be published online and in print.
Proposals covering content, depth and proposed fees should be submitted by email to Ms Christelle Vergnat, firstname.lastname@example.org by April 1st 2019. The proposals should also include a justification of the expertise of the author(s) and, if possible, an example of their previous work. Please include a conflict of interest statement detailing any financial, professional or business interest related to the topic of the report.
Proposals will be scored against the two criteria below. Proposed cost will also be scored and the three figures aggregated to yield the successful entry:
- Does the scope and depth of the proposal match the description above?
- Does the expertise and past performance of the authors indicate that the product will be of high quality?
All applicants will be notified of their success or otherwise by email by Friday 12th of April.
Any questions may be directed to Dan Bradley, email@example.com.
