Being "zero waste" means that we adopt steps towards reducing personal waste and minimizing our environmental impact.

Our community places a major focus on the 5 R's: refuse, reduce, reuse, recycle, and rot. We practice this by reducing consumption, choosing reusable goods, recycling, composting, and helping each other improve.

We also recognize excess CO₂, other GHG emissions, and general resource usage as waste.

Lomi "composter" & methane emissions question (beehaw.org)

Hi all! So, first thing's first - I know Lomi isn't actually good for composting. I bought mine secondhand for a fraction of the price because there's no food scrap drop off near me, and I am not interested in doing a proper home compost. I don't have any plants; I'm only interested in reducing my food waste.

One question that I keep coming back to, and that I've had a lot of trouble getting the answer to, is does Lomi actually reduce methane emissions? The website says yes: "With Lomi, food waste undergoes aerobic break down (in the presence of oxygen), meaning methane isn't produced. Then, when Lomi fertilizer is used in plants, carbon is sequestered in soil and plant matter." However... I'm not using it for fertilizing plants. I just use it to process food waste so I'm not just throwing it directly into the trash.

Does it compact the trash? 100%. We usually throw out the output after maybe 6 cycles; that's the equivalent of 5 freezer bags full of food scraps (mostly banana peels tbh). One thing I am 100% sure of is the fact that it reduces the frequency of my household taking out the trash, since it's not full of smelly food or attracting pests, and it weighs a ton less. But... is it actually reducing methane emissions? If my trash bag ends up in the landfill, will that aerobically-processed compacted food still release the same exact amount of methane emissions now that it's trapped in a bag with tons of trash above it?

Any help on this is appreciated. Thanks!

So from my understanding, methane is produced solely in the decomposition of the matter, so yes it does bring down methane emissions. The second part about carbon is, from my understanding, just saying that, as plants do, remove carbon from the air and convert to oxygen.

But I was actually coming here to check about lomi composting. Since moving I've had some trouble keeping up with composting since my city does not deal with waste from large apartment complexes, so no curbside composting. I have plants too so this actually might be helpful if I can find it used...

The area where I'm struggling is the fact that, to my knowledge, Lomi doesn't actually make the organic matter "decompose" - which means, presumably, it would still decompose when disposed of, right?

I got mine when I moved (used as well - only 150 bucks!) because it became way less feasible to drop off my organic waste in my new city. It definitely drastically reduced the amount of trash I had to take out (as compared to just... throwing everything out), and reduced smelliness in the trash. If it does actually reduce methane emissions, then I would say it's a great option. If it doesn't... then, well, it probably cuts down on trash loads and things like that, but I'm not sure that it would otherwise be worth it.

I've seen some people unhappy with the end product in terms of using it in place of regular compost; I know their "lomi pods" are pretty much required if you want to use it for plants - so you'll need to buy those (as well as filter replacements - although I'm pretty sure you can just use regular activated carbon pellets) - and it's possible some people weren't using those. Just something to keep in mind!
