Welcome to Swedish Ecology, or SwedEco, as we're often called

Swedish Ecology is a Swedish company that for more than 50 years have been developed and produced toilet solutions for households without sewers.

On the Swedish market, BioLet/MullToa has become so popular that the brand is sometimes used in a general sense to designate a biological toilet, regardless of the maker. For that reason, we need to provide some information here so that customers can avoid making an unfortunate mistake. If you want to make sure you choose the right brand, ask your retailer to show you a real BioLet/MullToa humus toilet, which does exactly what it promises.

Now you can certainly understand why BioLet/MullToa is Sweden's best-selling biological toilet.
