Why it passes our bar
Breeds all worms on its own farm in North Rhine-Westphalia — running since 1998 and self-described as Germany's largest worm farm — rather than reselling: "Auf unserer Wurm-Farm züchten wir Riesen-Rotwürmer." Its TerraVerm worm humus turns organic waste into a "100% natürlich ... chemiefrei" soil improver the site says revitalizes depleted soils — regeneration of soil is the product itself, though no third-party certifications are named.
