About this piece

Make home composting simple with the Eco King Composter, a durable outdoor compost bin available in two sizes for different households and gardens. Choose the compact 110-gallon model or the larger 160-gallon version. Both feature 2.3 mm walls made from 100% recycled polypropylene, a large double lid, two lower access doors, and an open-bottom design that allows beneficial organisms from the soil to reach the composting material. Made in Germany by GRAF, the Eco King provides a straightforward way to turn kitchen scraps and garden waste into useful compost.

Features & care

The Eco King Composter is a step up from the Eco Master, offering heavier 2.3 mm walls and a convenient double-lid design. Available in two capacities, it gives gardeners the flexibility to choose the compost bin that best fits their household and available outdoor space.

The 110-gallon Eco King works well for smaller households and gardens that generate moderate amounts of kitchen scraps and yard waste. For larger households or more active gardens, the 160-gallon Eco King provides additional capacity without taking up an excessive amount of space.

Both sizes use 100% recycled polypropylene for durable outdoor construction. The side panels snap together securely, creating a sturdy composting chamber without complicated assembly. GRAF's instructions also confirm that the Eco King assembles without tools.

A large double lid provides convenient access from above. The two sections make it easy to add leaves, garden trimmings, kitchen scraps, and other appropriate compostable materials. When finished compost is ready, two access doors at the bottom let you retrieve mature material without emptying the entire compost bin.

The Eco King uses an open-bottom design to keep the organic material in direct contact with the ground. This allows microorganisms and worms from the soil to enter the composting material and contribute to decomposition. For best results, GRAF recommends placing the composter directly on loosened soil rather than concrete or asphalt.

A soil grid is available separately for gardeners concerned about tunneling rodents. The grid helps deter unwanted access from below while preserving contact between the composting system and the ground.

Whether you're starting home composting or need a larger outdoor compost bin for an established garden, the Eco King offers a simple and durable solution. Finished compost can enrich vegetable gardens, flower beds, landscaping, and raised beds while helping put everyday organic waste to productive use.

Your questions, answered

What is the difference between the Eco King 400 and Eco King 600?

The main differences are capacity and overall size. The Eco King 400 holds approximately 110 gallons and measures 28" x 28" x 33" H. The larger Eco King 600 holds approximately 160 gallons and measures 31.5" x 31.5" x 37.5" H.

Which size Eco King Composter should I choose?

The 110-gallon model is a practical choice for smaller households, yards, and gardens. Choose the 160-gallon model if your household or garden regularly produces larger quantities of compostable kitchen and yard waste.

What is the Eco King made from?

Both sizes are made from 100% recycled polypropylene. The walls are 2.3 mm thick for durable outdoor use.

Why does the Eco King have an open bottom?

Direct contact with the ground allows microorganisms and worms from the soil to reach the organic material inside. These organisms naturally contribute to the composting process.

Should I place the Eco King directly on the ground?

Yes. GRAF recommends placing the Eco King on a flat area with direct soil contact. Loosening the soil underneath before installation can also help provide access for beneficial organisms.

Does the Eco King include a soil grid?

No. GRAF lists the soil grid as an optional accessory. It can be added to help deter tunneling rodents while maintaining contact with the soil below.

How do I remove finished compost?

Two lower access doors allow you to retrieve mature compost from the bottom without emptying all of the newer material from the top.

Does the Eco King require tools for assembly?

No. The Eco King uses GRAF's snap-together assembly system and does not require tools.

Do I need to turn the compost?

Turning isn't strictly necessary, but occasional mixing can help speed decomposition and promote more even breakdown of the organic material.

Can I use the finished compost for raised bed gardening?

Yes. Finished compost can add organic matter to vegetable gardens, flower beds, and raised bed soil. It can also be incorporated when replenishing or filling raised beds.
