My lab went from 4000 kg to 130 kg of waste a year
Tangentially, for home DIY projects. I'm often confused about what to do with half-used chemical products that I probably shouldn't pour down the drain or water the garden with. Things like termite coating or anti fungal finishes for timber.<p>Some builders I've spoken with tell me to pour it back into the container they came in, assume you still have left overs, because they can be re-used.
