An Ecobrick is a plastic bottle that has been packed with plastic, to a set density, forming a reusable building block. EcoBricks can be used to make modular furniture, garden spaces and even full-scale buildings such as schools and houses. Simply clean, dry and pack your plastic into a PET drinking bottle, to a minimum density of 0.33g/ml, and contribute towards building green spaces each month.
