Can household dust go in your worm bin?
No, household dust (e.g., from the vacuum cleaner bag) may not go in the Bonter worm bin. Household dust is a very heterogeneous mixture that often consists of human skin cells, hair, but also a significant portion of synthetic fibres from clothing, carpets, and furniture (which are microplastics). In addition, it contains outdoor dirt, insect remnants, dust mites and their droppings, bacteria, mould spores, small food residues, and unfortunately also residues of chemicals from household products, pesticides, flame retardants, and heavy metals from furnishings and electronics. Synthetic fibres and many of these chemicals and heavy metals do not break down in a worm bin, are harmful to worms, and permanently contaminate your compost with microplastics and potentially toxic substances.
How much household dust can you add?
None. Household dust is unsuitable for the worm bin, regardless of the quantity. Even small amounts can contain potentially harmful substances and microplastics that contaminate the worms or the compost. Due to the uncertain composition and the risks of contamination, therefore, never add this type of waste to your Bonter. There are many safer and more suitable materials (such as vegetable and fruit scraps, unprinted paper and cardboard) that you can compost.

What to do instead? Alternatives & waste management
Due to the uncertain, heterogeneous composition and the high probability of contamination with microplastics and chemicals, household dust (and the contents of vacuum cleaner bags) is not suitable for the Bonter or a traditional compost heap. The most responsible and safe destination for household dust from an average household is to dispose of it with residual waste. This prevents the spread of microplastics and other harmful substances into the environment through compost.

Tips for composting household dust
The most important tip is: never put household dust (e.g., from the vacuum cleaner bag) in your Bonter worm bin. The uncertain composition and the probable presence of synthetic fibres (microplastics) and chemicals make it unsuitable. Collect household dust separately and dispose of it with residual waste. For your worm bin, always use materials whose origin and composition you know and which are clearly suitable for composting, such as untreated vegetable and fruit scraps, clean paper and cardboard, and specifically suitable organic garden waste.
