Having tried various methods of making a single cup of coffee I have come down on the side of a individual "plunger" coffee pot. The knack is not to use absolutely boiling water - give it a few seconds to come off the boil as boiling water effectively burns the coffee and spoils the flavour (effectively this is what various drip methods do).
I have the shape of electric kettle that will work with just one mugful of water so not wasteful.
The plunger method produces less waste than methods which involve pre-packed capsules. I can put my loose coffee grounds in the compost bin but the capsules have to go in landfill or be burned - neither of which are good for the environment.
Don’t look for the light at the end of the tunnel. Stomp along and switch the bl**dy thing on yourself.
