HEY MATE HERE IS YOUR
virgin plastic
Virgin Plastic, is the resin produced directly from the petrochemical feed-stock, such as natural gas or crude oil, which has never been used or processed before.
The raw materials for plastic recycling plants are nothing but the used plastics from the consumers, basically which are also the virgin plastics.
Depending on how the materials are re-processed, recycled materials can never achieve 100% of mechanical properties of virgin materials. The degradation of these properties has a direct effect on safety factors and long term performance measure such as fatigue.
This is not to say recycled plastics cannot be used in various applications, but does explain why recycled materials often have lower safety ratings. It also explains why manufacturers have made a lot of headway using recycled materials for things like plastic bags and disposable packaging but are still figuring out the most effective way to use it for larger structural and infrastructure items. Often, if the product is structural, it may have to have a lower safety or strength rating if recycled materials are being used.
HOPE THIS HELPS YOU...
