INNTERCONECTA STEP 2025 PROJECT – CDTI. ReWoodTing
Research into nano- and bio-based coatings and recycled components derived from by-products of the timber and glass industries for decarbonised, functional, industrialised façades
About ReWoodTing
The REWOODTING project is an industrial research initiative aimed at developing a new modular façade solution based on wood, recycled materials and advanced technologies. This solution will combine sustainability, energy efficiency, renewable energy generation and smart monitoring.
TESELA is taking part in this project with the aim of contributing its expertise in advanced materials, nanotechnology, functional coatings and the recovery of industrial waste.
The construction sector accounts for a significant proportion of global energy consumption and carbon dioxide emissions. It is therefore necessary to research construction solutions that reduce resource use, improve the energy performance of buildings and facilitate the transition to a more circular economy.
Against this backdrop, the project aims to address some of the sector’s key challenges: reducing its carbon footprint, making use of industrial by-products, replacing potentially toxic substances, and improving the durability and performance of materials used outdoors.
What technologies will the solution incorporate?
The façade being researched as part of the REWOODTING project will combine different materials and technologies within a single construction solution:
- Modular systems that enable faster, more precise and better-controlled installation, whilst reducing the amount of waste generated during installation.
- Components manufactured from wood and by-products from the timber industry.
- Bio-based coatings and nanomaterials with hydrophobic and fire-retardant properties.
- Photovoltaic glass capable of generating renewable energy within the building itself.
- IoT sensors and tools to monitor the condition of the façade and facilitate its maintenance.
The integration of these technologies will pave the way for more efficient, functional and durable prefabricated façades. Furthermore, the aim is to reduce both the environmental impact of the materials and the maintenance requirements throughout the buildings’ lifespan.
TESELA’s role in the REWOODTING project
As part of the project, TESELA is leading research into new nano-based coatings and is involved in the development of sustainable components for the construction of the façade.
Specifically, TESELA will focus on two main areas of research:
- The formulation of functional coatings containing nano-clays, zinc oxide (ZnO) and titanium dioxide (TiO₂), designed to improve the water resistance, fire resistance and ageing resistance of wood-based components.
- The development of new composite boards made from cement and wood, incorporating recycled fibres and biomass ash to reduce their environmental impact and promote the use of industrial by-products.
The new coatings will be assessed to evaluate aspects such as their adhesion, stability, durability, fire resistance and behaviour when exposed to water. Their compatibility with the materials and application procedures used in the construction sector will also be examined.
In the case of cement-bonded particle boards, research will be carried out into the incorporation of recycled raw materials and cements with a lower environmental footprint, with a view to maintaining mechanical and thermal performance suitable for use in construction solutions.
A consortium spanning the entire value chain
The REWOODTING project brings together five companies with complementary capabilities: FINSA, NANOCEL, TESELA, ONYX SOLAR and ZEROHOUSING, in collaboration with the CETIM and XERA–CIS Madera centres.
The consortium’s composition enables it to address the entire value chain of the project: from the recovery of by-products from the timber and glass industries to research into new materials, the development of functional coatings and the integration of components into an industrialised façade on a demonstration scale.
This collaboration will also facilitate a joint assessment of the technical, environmental and industrial feasibility of the solutions developed.
Duration, budget and funding
The project will run from September 2025 to June 2028, with a total duration of 34 months and an overall budget of 2,272,289 euros.
REWOODTING forms part of the INNTERCONECTA-STEP 2025 call for proposals issued by the Centre for Technological Development and Innovation (CDTI) and is co-financed by the European Regional Development Fund (ERDF).
This initiative is in line with European priorities relating to advanced materials, the circular economy, decarbonisation, energy efficiency and the development of clean technologies.
Through its involvement in the REWOODTING project, TESELA is reinforcing its commitment to research into advanced materials and to the development of innovative solutions to move towards more sustainable, safer, more efficient and decarbonised construction.
