The opening angle of the lid is designed to be less than 60 ° to keep it closed when not in use so as to isolate wastes from fire source and limit the amount of oxygen. The risks of spontaneous combustion are therefore eliminated effectively. Moreover, The cylindrical structure and heightening type bottom can promote the flow of air around the bucket, and the full-steel construction with epoxy resin spraying make the product more durable and chemical resistant.
