CanO Water has built its pitch on aluminium's recyclability versus plastic, but lacks any quantified environmental data to back claims. No emissions targets, no supply chain transparency, no water impact assessment despite water being its core product. The company operates as a 24-person distributor with outsourced production and founder-driven sustainability messaging that simplifies material trade-offs.
