New plastic material can be recycled again and again
A new material called PDK can be disassembled and reassembled at a molecular level.
PDK monomers, however, can be completely separated from their additives simply by immersing the object in a highly acidic solution. "With PDKs, the immutable bonds of conventional plastics are replaced with reversible bonds that allow the plastic to be recycled more effectively," explained team leader Brett Helms. Objects made with the material can then be reshaped, recolored and upcycled again and again and again. A watchband could become part of a keyboard, which could then be used to make a phone case.

Cool stuff. Plastics are obviously a massive problem, so being able to re-use them like this could really help reduce waste.
