EROI Drink (エロいドリンク) is an energy drink made from Japanese Knotweed, an invasive alien plant pervasive in the Netherlands. We especially focus on sourcing unpolluted strains by working with water management companies and a nature conservation organisation.
The drink is named after the term "EROI" which stands for Energy Return on Investment, a measurement increasingly becoming critical in an era ever more finite. "エロい (Eroi)" simultaneously implies romantic in Japanese, representing the Utopian ecology conceived around the drink.
The unwanted nature of an invasive species puts itself in a similar position to the wind or the sun, an abundant energy source. When combined with zero-emissions transport, an extremely high EROI beverage can be produced, namely, the EROI Drink.
