Procedure
Aircraft X from ZZZZ to ZZZ my crew and I locked off a lavatory to store bio hazardous waste along with trash we were unable to stow in carts due to a lack of space. This report is simply to explain the reason such action was taken. Upon leaving ZZZZ we had 212 passengers; consisting of adults; infants and children. The flight was originally blocked for 10 hours and 45 minutes; however; about 3 and a half hours into the flight there was a medical emergency that resulted in the contacting of Med-link; the utilization of medics on board the aircraft; and essentially the use of said medics finger prick stick to check the affected passengers oxygen levels. Upon completion of this check; the finger prick stick was placed in the red sharps container retrieved from our EEMK (emergency medical kit) for disposal. This container was then wrapped in a red hazardous bag and placed in the aft lavatory to be locked off. The medical emergency resulted in our diversion into ZZZZ1. While on the ground; several beverage services were provided based on the time experienced on the ground. Prior to departing; it was asked if trash could be removed from the aircraft to free up space for the continuation of the flight; unfortunately the ground representative was unable to assist and implied the trash must remain on board. Once back in the air to continue on to ZZZ another passenger appeared to us ill. They filled several air sickness bags of vomit which were also collected; wrapped in a red hazardous bag and also placed in the aft lavatory that had been locked off on the previous portion of the flight. After providing the final service and setting up for final trash pick up; we were unable to create any further space to dispose of trash so that too was stowed in the aft lavatory that had already been closed off for the remnants of our medical emergencies.I am aware stowing trash and locking off the lavatory is against regulation; but being that the lavatory was already being used for bio hazardous waste we did it. Any suggestions for future experiences of this or was this an acceptable action?
