Someone mentioned filling their kettle up to make tea, which I tend to do. That’s mainly because when I make a mug of tea, it’s a proper mug! It’ll take an entire can of soup, with enough space left at the top to allow for some water to be put into the can to rinse out what’s left and top up the mug before I stick it in the microwave.
When I’m at work, I have to fill it up the night before so I can make a smaller mug in the morning, as well as fill my flask with green tea for the day.
I have stopped buying disposable plastic tooth brushes, I can now buy bamboo ones with bio-nylon bristles that can actually be composted! There’s a little shop in town that does all sorts of cleaning stuff that’s environmentally friendly and with refillable containers, which I’m going to investigate as and when things run out.
