Raw Materials
Of the major synthetic fibers, polypropylene (PP) is the only one that is created as a by-product—with lower greenhouse gas emissions and lower energy use than other fiber resins.

Manufacturing
Manufacturing PP fiber from polypropylene is a process with low impact on the environment—no toxic waste, no toxic emissions, no fluorocarbons and no halogens.

Converting
The manufacture of products from PP staple fiber has low environmental impact:

• Low melting point reduces the amount of energy needed to create products
• Low moisture pickup requires less energy to dry products (if needed)
• Scrap/waste from converting operations is recyclable/reusable in manufacturing operations
• No toxic emissions or wastes

Use in Product Manufacturing
PP fiber has many properties that contribute to sustainable use. PP fiber is: 

• Chemically inert, so it doesn’t break down with harmful effects on health or the environment
• Low in density, so less of it is needed than other fibers to make products
• Durable, so products using it can last longer and don’t need rapid replacement
• Easily cleaned without high energy or environmentally unfriendly methods

Disposal
PP staple fiber has a very high calorific value when incinerated as part of a mixed waste stream, providing a high energy value for the amount of CO₂ emitted. It’s also clean burning, with no toxic emissions.
