What do I do if I only want to compost “kitchen waste”?
Not everyone has a garden with shrub cuttings, leaves, or grass clippings. Many households want one thing above all else: to make good use of their daily kitchen waste. That's exactly what the SUPERCOMP compost bin is ideal for this purpose. It allows even pure kitchen waste to be composted cleanly, efficiently, and odor-free, producing high-quality humus—without any complicated steps or additional effort.
How kitchen waste composting works with the SUPERCOMP
Balancing kitchen waste correctly
You can use the SUPERCOMP can also be used to compost kitchen waste only. The SUPERCOMP has been successfully tested under demanding conditions at Graz University of Technology and the Joanneum Research Center – including with only orange peels and fresh grass clippings.
For "pure" kitchen waste composting, it is recommended to add a small handful of rock flour every two weeks to stabilize the process. Paper napkins and uncoated paper are also suitable for balancing the material and promoting an even structure.
The valuable compost worms in particular benefit from the added paper fibers and contribute significantly to the production of particularly high-quality worm compost (worm humus). Compost worms are relatively expensive to buy—in some cases even more expensive than high-quality meat—and their worm humus produces a correspondingly valuable compost product.
Which kitchen waste is particularly suitable
- All cooked or raw fruit and vegetable scraps, including citrus fruits
- Coffee grounds and filters
- tea bag
- Eggshells (crushed)
- Fish and meat scraps (cover)
- Bread and baked goods
Which materials balance the compost

- Cardboard and paper in small pieces
- Sawdust or wood shavings
- Leaves, hay, or straw
- Paper bags and egg cartons
Why the SUPERCOMP is ideal for kitchen waste
The SUPERCOMP ensures a stable, odor-free composting process thanks to its vertical ventilation. Even with nitrogen-rich kitchen waste, the compost remains loose and active. Compost worms and microorganisms find ideal conditions without the need for turning.
What advantages does a composter generally offer?
A composter reduces organic waste, saves on waste disposal costs, and produces valuable soil. Kitchen waste in particular can be turned from daily waste into a sustainable raw material for plants.
