Grey2Green Guatemala

From waste to resource

Grey2Green is a decentralized system that collects, treats, and reuses grey water from bathroom sinks. It takes advantage of this waste and converts it into a resource for irrigation of non-edible plants in the house. It is an ideal system for people who are plant lovers as it can collect and treat 168 liters of greywater per month, eliminating the use of fresh water in irrigation to 0 liters. As a result, there are freshwater savings, optimization of greywater quality, and familiarization with greywater reuse.
