While styrofoam has incredible uses, it is a harmful pollutant to the environment itself. The way it is made makes it non-biodegradable, and it is not actually known how long it takes to biodegrade. It can only be destroyed in specialised incinerators in a safe way, and burning it otherwise will create pollutants.The heat it is exposed to in landfills causes a contaminant to be released that can destroy the ozone layer and also cause added pollution. It is made from styrene, and prolonged exposure to this can cause several health problems for workers. In addition, it can also be a choking hazard to animals that feed from the landfills.
