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.
