Main highlights

Versatile – Our new and improved expanded metal composter made of galvanised and additionally powder-coated steel offers outstanding durability and corrosion resistance. The composter is ideal for long-term composting without annoying and compost damaging zinc shedding (hot dip galvanizing).
Sustainable use: Our metal composter transforms organic waste into nutrient-rich compost and thus makes a valuable contribution to sustainable garden practices and the environment. It not only supports waste reduction, but also promotes the health and fertility of your garden.
Safe – The finely woven grid construction prevents lawn cuttings from escaping and effectively protects against unwanted animals, for an undisturbed composting process. This barrier ensures that your compost remains safe and intact while producing nutrient-rich soil.
Easy to use: thanks to the close-meshed grid structure, which allows optimal ventilation, our compost container promotes the decomposition of organic materials and thus supports fast compost production. The improved air circulation speeds up the composting process, making your garden soil more quickly enriched.
Easy to install: Benefit from an uncomplicated and precise plug-in system assembly thanks to the optimised connection system (assembly instructions included in the package). In addition, the finished compost is much easier to remove than conventional plug-in systems that require complete disassembly.
