Why is expanded polystyrene bad?

Why is expanded polystyrene bad?

Polystyrene is slow to degrade, and if disposed of improperly, the foam can leach chemicals into the environment harming water sources. Polystyrene manufacturing is an enormous creator of hazardous waste. Furthermore, polystyrene manufacturing greatly contributes to global warming.

What is the meaning of expanded polystyrene?

Expanded polystyrene (EPS) refers to a rigid, tough and lightweight thermoplastic product. EPS is generally white and made of pre-expanded polystyrene beads. EPS is ideal for the packaging and construction industries due to its light weight, strong and excellent thermal insulation properties.

For what would you use expanded polystyrene for?

Expanded PolyStyrene (EPS) is a white foam plastic material produced from solid beads of polystyrene. It is primarily used for packaging, insulation etc. It is a closed cell, rigid foam material produced from: Styrene – which forms the cellular structure.

Is expanded polystyrene safe?

According to the U.S. Environmental Protection Agency and the U.S. Centers for Disease Control, polystyrene beads used in bean bag filling are 100% safe. Virgin expanded polystyrene beads are the Number One choice for bean bag fillers.

Why did McDonald's stop using Styrofoam?

It stopped using foam packaging for hot beverages in 2012 after receiving pressure from As You Sow, a nonprofit that promotes environmental and social corporate responsibility. The only remaining foam used in McDonald's stores today is for cold beverages.

Is high impact polystyrene toxic?

While that might lead you to believe it is entirely safe, some studies have reported “potential health impacts from polystyrene foam food packaging associated with its production, and with the leaching of some of its chemical components into food and drink.” Note: Polystyrene is flammable and similar to other organic ...

Is EPS cladding safe?

Expanded Polystyrene (EPS) has become known for its role in smaller combustible cladding fires over the last 20 years due to its very flammable composition. Like ACP, this material is a very dangerous, flammable material that has many advantages as a building material despite this issue.

What is the difference between extruded and expanded polystyrene?

What is the Difference Between Expanded and Extruded Polystyrene? Expanded polystyrene or EPS is a thermoplastic foam material that we produce from solid beads of polystyrene whereas the extruded polystyrene or XPS is a foam material that we produce from solid polystyrene crystals.

What is the difference between EPS and PIR insulation?

Expanded Polystyrene (EPS) has been left completely unaffected by the shortage of PIR insulation, as the manufacturing of EPS requires different raw materials. The cost difference between EPS and PIR can be as high as 20 percent, meaning you should see a substantial savings when you make the switch to EPS.

Is Styrofoam safe for house insulation?

Avoid foam insulation, whether board or spray-applied, whenever possible. Foam insulations commonly contain highly toxic flame retardants, and spray foam contains asthma-causing isocyanates. If foam insulation must be used, avoid products that are reacted on site, such as spray foam.

How to dispose of expanded polystyrene?

• Expanded polystyrene should be placed in the waste bin. Polystyrene is also sometimes used for other food packaging like multi-pack yoghurts. Some local authorities accept it in recycling collections although it is unlikely to actually be recycled. You can check with your council if they accept it.

What is expanded polystyrene (EPS) exactly?

• What is Expanded Polystyrene (EPS)? Expanded Polystyrene Properties and Key Benefits. Thermal Properties (insulation) - EPS has very low thermal conductivity due to its closed cell structure consisting of 98% air. Extruded Polystyrene Vs Expanded Polystyrene. XPS is often confused with EPS. ... Applications of Expanded PolyStyrene. ...

What is extended polystyrene?

• Expanded polystyrene is a plastic foam material that has certain desirable properties because of its structure. It is extraordinarily light and buoyant, and a good insulator against heat and sound. It can be used as a building material or a design element, and can be molded into many shapes for a number of household uses as well.

How is expanded polystyrene beads made?

• Expanded Polystyrene is made by injecting thousands of polystyrene beads into a rectangular or special shaped mold. The polystyrene beads are heated with steam. The bead will then soften and expand up to forty times its original size. At first the beads expand outwardly inside the mold until there is no more room.
