So a container for your wrapped product? That gets full of random lint and dust? Meh.

This is how your parents and grandparents lived. Stuff got dirty, and instead of tossing it after having used it once, they.. washed it! When I go shopping, I: * bring my own bag * buy oat, rice, sugar, pasta, chocolate etc in bulk (w/ textile bags I bring) * refill detergent containers in-shop * buy fruit & veg without packaging .. and I have no meaningful reduction of my living standard. I know it's difficult to ma…

FWIW, if you're curious about the insights from somebody who's crusty enough to make their own protein bars :) If you care about avoiding "processed foods" in other domains and are consuming shrink-wrapped bars with a shelf life of 2+ months: here be dragons! I store ours in a glass container the refrigerator, where they're individually wrapped in butcher paper. I'd consider them good outside of the fridge (in the pa…

I find most "protein" bars, processed or unprocessed, are relatively low in protein and function more like energy bars, meal replacement bars, or even weight gainers. I expect the ones made without processed ingredients like protein powders to be especially in that category. Not that there's anything necessarily bad about that, but it does bug me when folk label products as "high" in protein when all the protein come…

That was news to me, although I guess I'm not surprised. It's frustratingly difficult to buy groceries at the supermarket without plastic.

We compost many things at home, but cardboard boxes around food are a minefield. Most look like cardboard, but after you compost them you'll be picking out the plastic sheet that was bonded into them. One that particularly annoys me are cat food boxes. The cat food is separately wrapped (in unrecyclable foil-bonded-plastic, of course), and then the cardboard box containing those packets has a hidden plastic layer - f…

That's not sufficient macroeconomic justification to push the shellfish remains biofilm forward. See Cobra Effect [1]. This is reflexivity in action [2]. In the first year you start manufacturing this biofilm, your sentiment is true, it is using waste stream. In the Nth year, fisheries are collapsing shrimp stocks, flooding markets with shrimp to extract what used to be a waste stream to eke out ever decreasing margi…

Or you just consume the entirety of the waste stream and then stop because it's a low value marginal add on product that doesn't drive an industry. It's not like the demand for cow manure is driving us to create brand new herds simply to output more manure.

There is no bar for the massive amount of plastic trash we are putting in the ocean there though. The cranberry film would be about microplastics and damage to wildlife, not greenhouse gas emissions.

Who's "we"? I'm pretty sure developing countries don't throw plastic in the ocean, if only because there is already a non-green much more profitable alternative: burn it. In Europe there is a well set up "recycling" industry that takes plastic and burns it at high temperatures for applications like cement making. Not great, not terrible, and definitely not throwing away money in the sea.
