Compost Bin BRADAS TQ-K09075BOX — 400 L HDPE, adjustable diameter up to 750 mm, height 900 mm, black

BRADAS compost bin TQ-K09075BOX is a 400-litre outdoor composter made from high-density polyethylene (HDPE) in black. The cylinder-shaped unit has a fixed height of 900 mm and an adjustable diameter that expands up to 750 mm, allowing for stable placement on uneven ground or adaptation to available space. Designed for home garden and backyard use, it provides containment and controlled aeration to support the natural decomposition of kitchen scraps and garden green waste.

Advantages

The HDPE construction ensures resistance to moisture, rot and most weather conditions, while the 400 L capacity accommodates weekly household organic waste for a small to medium-sized family. The adjustable diameter offers flexibility during installation and helps maintain good contact with surrounding soil for heat retention. Built-in ventilation features support aerobic decomposition, reducing odours and speeding up the composting cycle compared with fully sealed containers.

Suitable for

• Home gardeners and households producing kitchen scraps and garden trimmings
• Backyard composting of leaves, grass clippings, fruit and vegetable peels
• Users who need a mid-size compost container with flexible footprint

When it may not be suitable

This composter is not intended for indoor use or for composting large volumes of woody material that require larger, specialised tumblers or industrial systems. It may be less suitable for users who need extremely rapid turnover or mechanical mixing features, as the design relies on passive aeration and manual turning.

Key specifications

• Material: high-density polyethylene (HDPE)
• Capacity: 400 litres
• Adjustable diameter: up to 750 mm
• Height: 900 mm
• Colour: black

How to use

Place the compost bin on bare soil or a well-drained surface in a shaded or semi-shaded area of the garden. Adjust the diameter as needed so the base sits evenly; the height is fixed. Start by layering coarse brown materials (twigs, straw) at the bottom to improve airflow, then add alternating layers of green (kitchen waste, grass clippings) and brown (dry leaves, paper) materials. Maintain moisture similar to a wrung-out sponge and turn or mix the contents occasionally to introduce oxygen and speed decomposition. Avoid adding meat, dairy or large quantities of oily food to prevent pests and odours.

What to consider before purchase

• Available outdoor space and whether a 400 L capacity matches your household waste volume
• Placement on soil for drainage and contact with soil organisms that aid decomposition
• Whether passive, manually turned composting meets your expected processing speed and convenience needs

Usage recommendations

For best results, balance green and brown inputs, keep the pile moist but not waterlogged, and turn the contents every 2–4 weeks. Regularly check for proper aeration and avoid adding prohibited items such as cooked food, bones or pet waste to maintain a healthy composting environment.
