Dissolve the tab with water and the bathroom, glass or all-purpose cleaner from EverdropThe Munich-based startup offers household cleaning products such as bathroom or all-purpose cleaners in tablet form, which can be dissolved in reusable bottles. Consumers can thus avoid single-use plastic – because they don't have to keep buying new plastic bottles – and reduce CO2 emissions caused by the transport of water with conventional cleaning products. Everdrop has now expanded its product range to include laundry detergent. The key here: The laundry detergent is adapted to the consumer's local water hardness. This is intended to avoid unnecessary surfactants when washing. The water hardness is determined based on the customer's zip code. (Photo: Everdrop)
