I have about 20 long-expired bottles of Soylent in my pantry, and I need to empty them out so I can reuse the bottles as containers for various things. I was wondering what to do with the expired liquid product inside them. Would it be useful as fertilizer? Or should I just flush it all down the toilet?
You could just drink it. Most likely it’ll be fine other than lower-than-wanted amounts of some of the vitamins.
I too have some expired bottles because of a large gift. The expiration dates were more about the vitamins loosing potency. They taste fine are delicious & satisfying. Drink up cheers
Yep, just drink em. Unless they’re like 5 years past the expiration, I wouldn’t think twice about it. And even then I’d give them a smell test and if they smell fine, I’d still drink it. Nothing in them “goes bad”, the only thing that could happen is if the bottle seal didn’t stay sealed properly and mold or something started growing in them, but if that happened, you’d be able to smell it or see it very obviously.
Sorry, I should have clarified: I’m not going to be drinking it. I’m not looking for a discussion about expiry, etc.
So, does anyone have any insight on whether it can be used as fertilizer or anything else productive? Or should I just flush it down the toilet?
Flushing it seems like an extreme waste. Donate it to someone perhaps? It’s totally safe and drinkable.
I have no idea how it would work as a fertilizer. My gut tells me that while it’s got some useful components, it also has some harmful components (for plants) and could cause soil issues (maybe?).
Well, possibly. Possibly not depending on the plants and application.
you’d have a large buildup of organic material on the soil surface If you pour a bottle on top of a plant. This would potentially create a anaerobic environment where the roots wouldn’t receive enough oxygen. This will also have a rotting/sulfur smell.
There are traditionally ratings for fertilizers showing the exact ratios of nutrients. Since soylent wasn’t made as a fertilizer, you wouldn’t know and depending on the plant/type of plants it could prove a bacteria filled smelly mess.
if this is being used as an aquatic fertilizer (water lilies, hyacinth, algae) I’d just pour the bottle in your water planter or pond. If the Soylent is diluted in a larger volume of water with active bacteria (like that found in water planters and ponds) the decomposition of a 400 kcal bottle of soylent should be easily converted in the nitrogen cycle to something the plants can use.
