What do I do if I only want to compost “kitchen waste”?

Not every household produces large amounts of yard waste—often, the main waste consists of kitchen scraps that need to be put to good use. This quickly raises the question of whether it’s even possible to compost kitchen scraps on their own without any problems. Many people worry about odors, an unstable composting process, or extra effort. But with the right system, this form of composting can be carried out easily, cleanly, and efficiently—and daily kitchen scraps are transformed into valuable humus in no time.

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.

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.
