The alternatives to the plastic bags aren't exactly stellar examples of environmentalism. IIRC, paper bags are more energy intensive to make than the single use plastic bags, and require trees. The washable ones get nasty fast, and have to be washed pretty frequently. IIRC, the end result of that is they also require more energy overall than plastic.
I’ve been using canvas bags for ten years or more. They don’t get nasty. What are you doing, throwing raw meat in there? I get a few onion skins to shake out from time to time and I do wash them every couple months just on ceremony.
What plastic bags I might accumulate I use to wrap paint brushes and rollers if I need to use them the next day.
Really this.
I keep my shopping stuff in the trunk of the car. Three assorted sized cardboard boxes that nest, and a big tote bag with some disposable plastic bags in the small bag. I hardly ever use those, but sometimes.
Most of the check out clerks at Aldi's know me well enough to know what goes in which box, and why. Frozen food and meat in the little box. Canned goods in the medium box. Everything else in the big box, or on top. I hardly ever have to explain this to new people more than 3 or 4 times before they are properly trained.
