At work we return all toners to the manufacturers for recycling. Also there are companies which will collect tech and electrical stuff for recycling - anything from a broken desklamp or a dead mobile to an old photocopier. The company we use needs a minimum of ten items so we save them up and have a collection every few months (also bring in bits from home to make up the numbers and save a trip to the tip).
I don't use bar shampoos or soap, but I do use a 2-in-1 shampoo/conditioner and rinse but not repeat.
We buy Encore cat food which comes in tins or sachets - the sachets are plastic but at least they can be recycled.
We have cling film but I can't remember the last time I used it. We use plastic
Chinese takeaway containers for food storage and for sandwiches.
We have an allotment so grow a lot of our veg and we're getting quite good at timings so we also have more fresh stuff over winter (and not just bloody sprouts!).
Have used re-usable shopping bags and baskets for decades but if we do get an online shop, we'll choose a slot where there is already a local delivery booked (Sainsburys - or do they all do this?).
Loads of other things but they've all been mentioned several times. Anyway, last but not least... ahem, no children
(to be fair, that wasn't our decision!)
Our financial and environmental extravagances are heating and flights
And when I was having periods, I would certainly have tried a Mooncup but other types of reusable sanpro wouldn't have been for me.
