We do something similar in-house. Our housekeeper stores large, bulk versions of all of our preferred liquids and refills them periodically. It’s not nothing, but how much waste doesn’t that really conserve in the grand scheme? It’s certainly minuscule compared to the mountains of food containers that get tossed out by the carefree people that live in my house rent free.
It drives me mad when I see a second bin get grabbed by the garbage man and wheeled to the truck. I compare that to the retired couple across the street who put out a half filled blue recycling bag and almost no food waste. They are both retired Indian doctors. I know they grow a bunch of their own food and probably eat mostly vegetables. I almost never see the Amazon or ups trucks stop at their house either. While our front door is barraged by the delivery trucks daily with packages.
Those packages are emptied of whatever junk we just couldn’t live without. Then the waste is carried out and broken down by me to see if I can make it all fit into the green bin.
It’s a trash centipede from the truck, to the front door, to the back alley and then to the big blue truck. I have got to get them better about their ordering habits. It’s going to just be plastic containers, cardboard boxes and turtles all the way down.
