The article said that the whey was "toxic" because if put it in a lake or stream it will consume the oxygen and kill the fish. That's mostly just FUD, hype, and nonsense: The water treatment industry is very aware of 'biologic oxygen demand' (BOD). Basically, yes, decomposing some whey in a lake will consume some oxygen from the lake. Consume too much oxygen and then will kill the fish. Sure. But that doesn't make the whey "toxic". Indeed, lots of things go into the streams, rivers, and lakes that consume oxygen. If don't consume too much oxygen, then likely fine. No problem (at least about oxygen). And, of course, what consumes the whey is biologic activity that might make the water better for plants, fish, etc. Sure, go to a big city sewage processing plant. What do they do? Sure, bubble air through the dark liquid! Or, they follow the recipe, "Add air and stir."! Net, the article looks like traditional newsie stuff -- claim the sky is falling and get eyeballs and ad revenue. Smelly bait for the ad hook. Make people feel guilty from their 'sins' of their consumption of thick yogurt and what they pour down their drains. Deliberate, confused, nonsense guilt trip. Bummer. For over 20 years, I've poured lots of stuff down my kitchen drain. Too old, sour milk has been a common item. Much worse, when I feed canned cat food to my kitty cats, they often don't eat all of it, and, being smart little kitty cats, don't eat it at all after it becomes old and dry. So, then I have to clean out such food dishes for them. To do this I soak the dishes overnight in water with detergent, rinse the dishes, and flush the rest. And I'm 'destroying the 100% all-natural, pure, pristine, precious, sensitive, delicate planet'? I don't think so! Instead all the 'stuff' from the kitchen and bathrooms goes through big, white plastic pipes to a big concrete tank sunk in my backyard. The tank has some 'bugs' that reduce essentially everything into clear water, some methane gas, and a tiny quantity of solids. The gas floats off; the water goes into the drain field in my backyard; and the solids accumulate. The tank has been working fine for over 20 years without cleaning. For the water, the backyard loves it. Net, no worries. So, I'm not destroying the planet! And I'm not guilty.
