"Take a Plastic Bottle – Stuff it Full of plastic". All that is needed to make an Ecobrick is a plastic bottle or container of some sort (including paper / laminate milk cartons) and a stick to stuff and compress a whole bunch of random everyday plastic materials inside of it. To start an Ecobrick, take a plastic bottle, rinse it out and leave it to dry. Use a stick to stuff it layer by layer with all of the plastics, non-biodegradables, and synthetics that would otherwise be thrown into a waste bin and eventually the Earth.
