In order to fulfill our responsibilities as a manufacturer and seller of plastic products, our company is committed to promoting material recycling and the expansion of sustainable energy use. As part of this effort, we have established a system to regenerate the polystyrene foam generated during the manufacturing process back into PS pellets. Some of the regenerated PS pellets can be transformed back into raw materials for polystyrene foam, making it possible to re-manufacture them as polystyrene foam products. If you are interested in contributing to environmentally conscious manufacturing, please feel free to contact us. *For more details, please refer to the PDF document or feel free to reach out to us.*
