Styrofoam is considered very bad for your health and for the environment as well.
When Styrofoam is heated with food it supposedly leeches toxic chemicals in to your food which can then possibly cause you health issues and possibly cancer.
However there's a low risk of health issues or cancer from Styrofoam.
Styrofoam is not recyclable either and takes a long time to decompose in the landfills and they can leech chemicals into the landfills and soil and groundwater.
Some places have banned Styrofoam but other places have not and many people use Styrofoam containers and drink from Styrofoam Cups without any health issues.
Styrofoam is made of Polystyrene which is a polymer.
The Styrofoam that we use is just extruded and expanded Polystyrene.
Styrofoam is made from Polystyrene and so they are the same thing.
There's not much difference between Styrofoam and Polystyrene other than Styrofoam being a trademark name for Polystyrene.
Styrofoam is basically just expanded Polystyrene.
Styrofoam containers for food have been banned in the states of Maine and New York.
Styrofoam Itself is not completely banned in those states but it only applies to the Styrofoam Food Containers in restaurants and grocery stores.
Styrofoam is banned because it can be hard to dispose of and is considered bad for the environment and Styrofoam cannot be recycled so it has to go to the landfill or be burned.
It is safe to microwave Styrofoam Containers.
Styrofoam Containers are microwaveable and as long as you don't microwave the Styrofoam container too long then it will not or should not melt.
I have however before left a Styrofoam container in the microwave too long and it melted some but as long you just put the Styrofoam container in the microwave for only a minute or two to heat the food back up then it should be fine.
You can also microwave Styrofoam Cups to heat coffee and other drinks up as well.
You can heat coffee up in a Styrofoam cup in the microwave.
Styrofoam cups are microwave safe and you can place them in the microwave and heat up coffee, water, hot chocolate etc.
I've been microwaving Styrofoam cups for years now and never had one melt.
You can also microwave those Styrofoam food containers to reheat food in as I've done it several times before as well.
Just don't put gasoline in a Styrofoam cup as the gasoline will melt the Styrofoam cup.
However microwaving Styrofoam cups and Styrofoam food containers is safe and never have I had an issue doing so.
