Not Quite Zero but Getting Closer?

I have recently been hearing quite a lot about 'Zero Waste Warriors' in India and, now, the UK (https://www.theguardian.com/environment/2020/may/06/zero-waste-warriors-meet-the-people-whose-household-rubbish-fits-in-a-jam-jar). These people use combinations of buying unpackaged materials locally (especially foods); foraging (for edible leaves); refilling containers (with wine, shampoo and cereals et cetera) periodically; making stuff (like toothpaste) themselves; improvising with alternatives (for items like wrapping paper, cleaning wipes and pan scrubbers) and composting. They have consequently reduced their weekly waste to a tiny fraction of its former amount. The process does seem to take a degree of self-discipline and forward planning but many of the participants do seem very happy with their lifestyle. They can be gratified that their carbon footprints are reduced. A few mentioned that the Covid-19 lockdown, has made some processes harder.
