Some cleaning products use acetic acid of petrochemical origin, while other cleaning products use acetic acid of biological origin, i.e. vinegar. Petrochemicals are non-renewable and are the main cause of global pollution, while bio-based vinegar made from sugar should be a food source. The acetic acid used by CYCLE is fermented from biomass and is molecularly exactly the same as petrochemical and bio-based acetic acid, but is resource-efficient and recycled.
