REVERSIBLE ADHESIVES FOR BONDING AND DISASSEMBLY OF COMPLEX CONSUMER PRODUCTS
HEATEX
Motivation
Global textile production has doubled in the last twenty years, reaching a significant market value in 2023 with continuous growth anticipated until 2030. However, this increase in production has resulted in a low recycling rate of textile waste, with more than 85% of textile products ending up in landfills or being incinerated. This problem is particularly worrying for articles containing textiles in their composition, such as luggage, upholstered furniture such as sofas, chairs and car seats, where textiles are glued to wood, rigid plastic or metal structures.
The fundamental motivation is to address the challenge of recycling complex textile products, which generate large volumes of waste, through the development of innovative and sustainable solutions for joining and separating these materials.
Objectives
- Optimise the formulation of adhesive matrices for disassembly
- Characterise the physical and chemical composition of new adhesive formulations
- Optimise the working conditions of the disassembly equipment
- Assess the applicability of new adhesives in the textile sectors
Obtained results
-
Quantitative recovery of metals from black mass using sustainable solvents under appropriate operating conditions.
-
Partial selectivity towards cobalt, manganese, and nickel, with maximum recoveries of up to 70%.
-
Limited selectivity and need for additional treatments to obtain pure metals.
-
Demonstration of the feasibility and efficiency of contactless heating of adhesives containing magnetic materials.
-
Confirmation of thermal and magnetic stability and high industrial viability of the process for the rapid activation of hot-melt adhesives.
