For
disposing construction waste, it can be land-filled. Under the earth's surface, various microorganisms act on wastes or under anaerobic conditions, various components of waste gets broken down. But certain components of
construction waste such as plasterboard are hazardous once land-filled. When
plasterboard is broken down in landfill conditions, it releases hydrogen
sulphide gas. This gas is very toxic. It can cause health problems and even
death when it is inhaled, consumed or comes in contact with skin.
