How cost effective is washing trash at home, to using packaging that is either biodegradable, or inert (paper, and glass for example, as it has been done for decades before plastics got widespread)? Compared to this I keep hearing the bullshit that reusing glass is not environmentally friendly and a PET flask has lower carbon footprint, etc. I say bullshit. Also we should transport and sell less water (either with added sugar and CO2 or without), we have those pipes in the ground/walls at most places in the developed world, which supply us clean drinking water. We should rather focus on providing clean tapwater to everybody where it is not available, instead of selling water for 100x price in small single use containers. Reduce. Reuse. Recycle. These are the priorities.
