Polymers are long chains of molecules cross-linked by chemical bonds, making them very strong and durable. Common applications of polymers range from transport and building to food packaging. However, these plastics are difficult, if not impossible, to recycle, because they cannot be reworked once cured.

Scientists have unintentionally discovered a new kind of polymers that are not only stronger, but also lighter, cheaper and easier to recycle. The polymers can be broken down by dissolving in sulphuric acid at the right concentration. By doing so, they are self-healing, infinitely recyclable back to their starting material.

This discovery is a major breakthrough that addresses many global challenges. If the polymers can be applied to products that we use daily, for example, clothing, water bottles or furniture, they will not wind up in landfills and release toxins. Besides, during the manufacturing process, any defective parts can be recycled back to the pure starting form. This can significantly reduce costs and waste. The huge benefit brought to the environment is foreseeable.
