📋 目次
1How long will a 120L composter take to produce compost?
A 120L composter typically takes 3–6 months to fully break down organic waste, depending on aeration, moisture, and material balance. Adding a compost activator or turning the pile weekly can speed up the process by 1–2 months.
2What types of waste can I safely add to a 120L composter?
You can add fruit/vegetable scraps, coffee grounds, eggshells, and dry leaves. Avoid meat, dairy, oily foods, and pet waste, as they attract pests and slow decomposition. A 3:1 ratio of browns (dry) to greens (wet) keeps the pile healthy.
3Is a 120L size suitable for a household of 4 people?
Yes — a 120L composter is ideal for 3–5 people, assuming 10–15kg of food waste per week. Smaller households may fill it more slowly, while larger ones might need a second unit or a larger 200L+ model for faster processing.
4Should I choose a 120L open bin or a closed tumbler composter?
Open bins are cheaper and easier to load, but attract pests and smell more. Closed tumblers are more efficient, odor-free, and rodent-proof, but cost 20–30% more. Choose based on your space, budget, and how often you want to turn the pile.
5What accessories are worth buying with a 120L composter?
A compost thermometer (to monitor heat for faster breakdown), a pitchfork or turning tool, and a cover or tarp to retain moisture are all useful. A compost sifter can also help separate finished compost from larger chunks, saving time later.
