When you boil polystyrene in water:
-
It Melts Down – Polystyrene softens and shrinks dramatically in hot water. A large pile of foam can reduce to a tiny fraction of its original size.
-
You Can Reshape It – Once melted, you can pour it into molds to create blocks, sheets, or even art supplies.
-
It Becomes Compact and Sellable – Compressed and reshaped polystyrene is much easier to sell to recycling companies. They use it to make insulation materials, plastic products, and even construction materials.
⚠️ Safety Tip: Always boil polystyrene in a well-ventilated area. Do not inhale fumes. Use gloves and tools to handle the hot material.
đź’¸ Why This Can Make You Money
Recycling polystyrene is a business in demand because:
-
It’s lightweight and bulky, which makes transporting unprocessed foam expensive for recycling centers.
-
Boiled and compressed polystyrene is much cheaper to handle and sells for a premium to recycling plants.
-
Innovative makers also use it for DIY projects, crafts, and small-scale products, creating local market opportunities.
Some people in small communities have turned piles of discarded foam into hundreds of dollars per month just by collecting, boiling, and selling it.
