It has always boggled my mind that we don't reuse stuff more - maybe not the most cost effective but why don't we for instance have reusable containers for things like shower gel that can be refilled at the store or by a delivery/round process?
indeed, like the old milk bottles, or as the europeans have started doing glass bottles of almost all forms (seriously the german pfand does make you want to recycle more with minimum of hassle and you can still use the good ol' trash when you need to)
i think there's still a lot that legislation and manufacturers can do, there's a lot of unnessecary packaging.
take multipack crisps- why not 1 big bag with a re-usable ziplock bag for you to divvy out portions?
or bigger packs of common ingredients- like pasta or rice that aren't perishible to the same degree
and dont get me started on product packaging, like the example of the torx drivers earlier, there's really no need for protective packaging on some things
another example would be things like mobile phones- why bundle cables and chargers with the device? i have loads of unused phone chargers and cables because everything being microusb i just have one big charging brick that powers everything and a couple of standard cables
