As you grocery shop, think about where your food packaging will end up. Eggs often come in paper or foam casing. Did you know that paperboard packaging is the more eco-friendly option? It’s recyclable and biodegradable. Foam is less so because it’s made from polystyrene, or plastic #6, which is a petroleum product and often not recycled. Even if paperboard ends up in a landfill, it will break down and leave no harmful traces.
