The short answer
Compostable means a material can break down through composting when the right conditions are there: air, moisture, warmth, microbes and time.
11:02So it is not a badge that says chuck it anywhere and it politely disappears.
11:03Home-compostable and commercial-compostable are different claims. Home compost heaps are cooler and less controlled. Commercial sites are managed much more tightly.
11:04Compostable is a route. The route must be named.
Why conditions matter
A compost heap is not a magic hole. It is a living system. Treat it badly and it sulks.
11:08Exactly. Composting needs oxygen, moisture, warmth and tiny living things doing slow practical work. If those are missing, the claim may not mean what people think it means.
11:09Landfill is not a compost heap. The sea is not a compost heap. A kitchen drawer is very much not a compost heap.
11:10British green-claims guidance says disposal claims need evidence and clear caveats. If a product needs a particular composting route, shoppers should be told.
11:11What to check
First, check the word before compostable. Home compostable? Commercial composting? Garden composting? Those words change the answer.
11:16Second, check whether the whole thing is covered. Bag, ink, label, glue, sleeve. A half-claim can cause a full-sized headache.
11:17Third, check your local route. Council food-waste rules vary, so a good product still needs the right bin.
11:18Where Generation earth fits
Our lane is simple: food-waste caddy liners that fit the caddy, hold the scraps and carry a clear composting claim.
11:24Start with the caddy, not the slogan. Use the council bin checker, then choose from the Generation earth liner range.
11:25The least glamorous answer is usually the best one: correct size, correct use, correct disposal route.
