Product Overview

Upgrade your composting game with this 300L Garden Compost Bin, designed to create nutrient-rich soil quickly and efficiently. With four-sided ventilation, this composter provides excellent airflow, accelerating the decomposition process and producing high-quality compost faster.

The generous 300-litre capacity makes it ideal for households with regular garden waste, lawn clippings, leaves and kitchen scraps. The top locking lid keeps pests out and prevents wind from disturbing scraps, while the bottom pull-out door allows easy access to finished compost — simply scoop and spread.

Made from UV-resistant, BPA-free PP plastic, this compost bin is built for long-term outdoor use, even in harsh weather. The black colour helps retain heat, further speeding up composting.

Best of all, it assembles in just a few minutes with no complicated tools required. Lightweight, durable and efficient — it’s the perfect solution for gardeners who want to recycle waste and nourish their soil naturally.
