Monotube

While single-use plastic sachets and tubes are likely to end up in landfill, the Monotube from Tubex promises infinite recyclability. A clever snap-off nozzle means no pesky plastic lid, so this mono-material innovation really is 100% recyclable.

There is just one sticking point: even the most widely recycled materials can end up as waste if they are too small, so take-backs and education will be a big part of the puzzle here. There is work to be done behind the scenes, but with the right infrastructure in place this could be a serious game changer.
