Wooden compost bin vs plastic

Updated: October 2026

The black cone is already in the corner, and a timber kit on amazon.co.uk looks hotter because it is wood. Wooden compost bin vs plastic is a space and access choice, not a species contest. A cone suits a small plot and a trickle of waste. A wooden kit suits you when you have ground and you will turn it. Neither is a hot composter. The five timber listings, and no plastic ASIN, are on the [wooden compost bin comparison](/hub/raised-beds-greenhouses-and-compost/compost-bin-wood). Peter F. read the RHS, Gardeners' World, and Garden Organic notes on 19 October 2026. A qualifying purchase can earn a commission at no extra cost to you.

When the plastic cone is the better fit

The RHS says a compact plastic bin is often a good choice for beginners and small gardens. Gardeners' World says plastic holds moisture and heat and suits a small space on soil. A cone already has a lid, a small footprint, and a hatch near the ground. It fits a caddy of raw peelings, not a lawn's worth of cuttings. Once it is full you wait, because turning means lifting the shell. Fill-and-forget is about 6 to 12 months. This set has no plastic listing, so there is no dalek price. If the weekly waste is a bowl of peelings, stay with plastic. Litres and a lid, once you move to timber, are on the wooden compost bin buying guide.

When the wooden kit is the better fit

The RHS points larger gardens toward a wooden bay, and Guy Barter, quoted by Good Housekeeping, talks about two wooden bins so you can turn one into the other. The kept kits run from 305 litres to 603 litres, plus one sold as 95 gallons, all under 1 cubic metre. The RHS says a heap under that size still works, more slowly. The two Moutta kits list hatches and a lid. The dobar kits list neither. The cedar-titled kit claims a pull-out door and does not answer the lid question. Where the dobar bullets state it, the gap is 3.5 to 4 cm. The larch page also says about 1.0 to 1.5 cm, so that listing does not agree with itself.

Heat is not a species contest

Gardeners' World says wood insulates and that plastic holds moisture and heat. A slatted kit with no lid does neither job well. A 2012 study abstract, on bins of about 300 to 400 litres, found plastic ahead of wood on temperature in that one trial. It is not a test of these five listings. Garden Organic groups daleks, open bays, and simple heaps as cool methods. They rarely get above 60°C, can take up to three years, and may not kill weed seeds. Larch or cedar does not leave that group. The weekly mix is on how to use a wooden compost bin.

One recommendation with a condition

Stay with the plastic cone if the plot is small, the waste is a trickle, and you already use the lid and hatch. Move to a wooden kit if you can spare the ground, you will turn the heap, and a lid is in the box or a cover you will add. Meat, fish, dairy, and cooked food stay out of both. The food list and the mesh are on compost bin rats. A patio with no soil is a poor site for either open base. A cone on flags is the smaller experiment, and a 92 cm timber kit is the one to leave.

Common questions

Which is better, wood or plastic?
Plastic is the better fit when the garden is small and the waste is a trickle you will mostly leave alone. A wooden kit is the better fit when you have the ground and you will turn it, after you have checked the lid. Neither is better at being a hot composter. Garden Organic treats cones and open bays as cool methods.
Does wood stay hotter?
Not as a rule. Gardeners' World says wood insulates and that plastic holds moisture and heat. A 2012 abstract found plastic warmer in one 300 to 400 litre trial. Wide gaps, where the dobar bullets state 3.5 to 4 cm, lose heat and let rain in. A lid and a balanced mix matter more than pine versus the cone.
Is a dalek big enough?
It is big enough for a small garden and a steady trickle, which is the RHS beginner case, and then you wait through the 6 to 12 months Gardeners' World gives a fill-and-forget bin. It is small once a lawn fills it faster than it rots. This comparison does not price a dalek. The wooden kits here are 305 to 603 litres, still under 1 cubic metre.
Do I need a lid on wood if plastic already has one?
Yes, if you want the rain kept off, which is one of the four jobs the RHS gives a bin. Plastic cones bring a lid. In this timber set only the two Moutta kits list one. An open slatted top is not the same object as the cone you already own. A cover you add later is a different purchase from a lid in the package line.
Will either kill weeds?
Do not count on it. Cool heaps, which cover daleks and open wooden bays on the Garden Organic page, may not destroy weed seeds, and a cool bay can take up to three years. Keep seeded weeds out of both. Turning and a proper mix change the result more than the material of the wall.
Can I compost kitchen peelings in either?
Raw peelings, with browns, are normal in both. Cooked food, meat, fish, and dairy are the items UK council pages tell you to leave out, and gaps in a wooden bin do not make those foods safer. In England the weekly food-waste collection still exists for what the home bin should not take. That split is the rats page, not a reason to pick cedar.
