A pouch (18), made of a water absorbent polymer that expands and becomes a gel in consistency upon absorbing water and that is biodegradable, is placed in each bag (10) of lesser volume. An opening (12) in each bag (10) is unsealed to drain the bags (10) of the biodegradable gel, as by squeezing the bag (10) to force the gel from the bag (10). The collapsed bags (10) can be re-stored for future use and the gel biodegraded as by disposition the conventional sewage system.
