In 1988, the Society of the Plastics Industry (SPI) established a classification system to allow consumers and recyclers to identify different types of plastic. According to this classification system, each plastic product has a SPI number, which is usually on the bottom of the product, to distinguish different materials of the plastics.
To help our customers and readers better understand the different plastic types associated with each code number, 99P recycling has created a basic outline that can be viewed as below.
We 99P pay attention to every aspect of the rational reuse of plastics. Recycling is an easy tool that everyone can apply everyday to turn environmental protection into habits, and make a better living environment.
