Life Cycle Inventory Comparison: 9" Polystyrene Foam -vs- Coated Paper Plates

 

  Material Usage Energy Water Greenhouse Gas
Polystyrene Foam 60% Less 25% Less 45% Less 35% Less
Facts

 It takes about 60% less material by weight to make a foam plate than it does to make a paper plate of comparable functionality.  

Making, using and disposing of foam plates requires about 25% less energy* than paper plates of comparable functionality.  

*total renewable and non-renewable energy.  

Making, using and disposing of foam plates uses about 45% less water than paper plates of comparable functionality.

Making, using and disposing of foam plates generates about 35% less greenhouse gas emissions* than paper plates of comparable functionality. 

*assumes maximum decomposition in commercial landfill.   

 

1. Making, using and disposing of foam plates uses about 45% Less Water than paper plates of comparable functionality.
