PMM / Concept small sealer


The PMM uses a biodegradable material that keeps the seeds, sugars, liquids and so on separate, preventing mosquitoes from breeding in large numbers. "The trash is full, you should go to empty it." , "No, it's too dirty. Maybe insects are in it!" As we all know that the trash is infested with insects such as bacteria and mosquitoes, which can spread diseases like malaria. Whereas, the PMM can isolate the garbage effectively.
This new waste isolation product allows users to dispose of their trash safely.
