Dutch tech research institute TNO has developed a new method it says could drastically transform the landscape of electronics recycling.

With an increasing trend towards integrating electronics with plastics across various sectors, from automotive components to household appliances, the challenge of recycling and repair has become more complex.

But TNO says it now has found a solution which is based on an innovative disassembly technique. Electronics can be detached from their carriers at the end of a product's life cycle, facilitating 'efficient' recycling and repair processes.

No compromise

TNO's 'breakthrough' hinges on the use of a water-based layer that facilitates the disassembly of printed electronics. Applied between the electronic circuitry and the outer plastic layer during manufacture, this solution withstands rigorous testing conditions and demonstrates resilience against humidity and high temperatures. Moreover, the flexible nature of the water-based layer ensures the safe removal of plastics without compromising the integrity of the electronic components.

More printed electronics

The integration of electronics with plastics (printed electronics) has resulted in lighter, more visually appealing, and cost-effective products. Yet, it poses growing obstacles to traditional recycling and repair methods. TNO's method addresses this challenge head-on, offering a pathway towards circularity in electronics manufacturing.

Overcoming recycling challenges

The fusion of electronic components with plastics in printed electronics presents a formidable challenge. Current recycling methods often entail shredding or incineration, leading to higher CO2 emissions and the loss of valuable raw materials. With only a fraction of electronic waste being effectively recycled, the environmental ramifications are profound, with estimates suggesting a surge in electronic waste to 74 million tonnes by 2030 and 110 million tonnes by 2050.

The global market for printed electronics is seeing spectacular growth, with projections indicating an increase in value from US$ 175 (EUR 164 million) to over US$ 3 billion between 2022 and 2032.
