The insiGlue project aims to develop an in-situ, formaldehyde-free, bio-based adhesive system for the production of MDF (Medium-Density Fiberboard). This system uses biological materials available on the market at low cost, eliminating the need for conventional adhesives. The resulting MDF will have reduced emissions, contributing to sustainability in the furniture and construction industries.

Paulo Magalhães, R&D Manager at Sonae Arauco, highlights:

"The wood-based panel industry currently relies on the use of mainly formaldehyde-based binders. Several market factors are driving major changes in the composition and technology of these adhesive systems in the EU. On the one hand, formaldehyde regulations are becoming increasingly stringent and, on the other, there is a need to reduce global warming potential in line with the industry's sustainability goals. Finding alternatives to formaldehyde resins, particularly bio-based options, will help to meet these regulations and the growing demand for environmentally friendly products, promoting the use of renewable resources and reducing dependence on fossil-based chemicals".

The project was born out of an in-depth study into sustainable alternatives to conventional adhesives used in the production of MDF. It was found that traditional formaldehyde-based adhesive systems are facing increasing environmental and regulatory challenges. Therefore, insiGlue proposes an innovative solution: an in-situ, formaldehyde-free, bio-based adhesive system using accessible and sustainable raw materials.

Building on the pilot study, the aim of this research project is to develop a reliable process for the production of highly sustainable, low-emission MDF with marketable material properties.

MDF is widely used in furniture and construction industry, being produced economically and sustainably from regionally available and certified wood. Through this research project, we are aiming to make MDF even more sustainable.

By participating in this project, Sonae Arauco strengthens its position as a benchmark for innovation and sustainability in the sector. The benefits are clear: reduced emissions associated with MDF, better alignment with future environmental requirements and a more competitive and environmentally friendly product.

This project, which started on 1 January 2025 in partnership with Fraunhofer WKI, complements the company's strategic initiatives, such as the world's first fibreboard recycling line in Mangualde, scheduled for the second quarter of 2025.
