Designed like a flexible plastic spring, the Trash.zip is a compressible trash can be downsized or upsized according to the amount of garbage disposed. You simply need to line it with the appropriate-sized disposable liner and set it aside. According to the designer, nearly 40% in materials used and weight will result in savings and over 50% of trash’s volume will be condensed so as to release more of the bag’s capacity. In essence this also means less garbage bags used.
