Environmentalists worry that the large-scale use of plastic packaging will pollute the environment and try to make manufacturers find ways to recycle plastic materials. However, despite their efforts, the recycling rate of plastic products is only 6.5%. The recycling rate of glass containers is 33%.
The statement 'The quality of products produced from recycled plastic is poor, while recycled glass does not have such a problem' is not helpful in explaining the relatively low recycling rate of plastic products.
