We need to pay extra attention to waste disposal in recycling. At the recycled plastic base, sometimes we can smell an unpleasant odor, which is directly related to the raw materials. The following are examples

We found during the material recycling process that a company producing PP recycled materials bought ten tons of raw material woven bags filled with sulfur. The raw materials were good and the price was reasonable. However, after buying them, they were placed together with other white raw material bags. When they were cleaned and sent to the granulator for production, there were problems. A pungent odor made people feel uncomfortable to breathe, and continuous ventilation was not enough. The resulting particles foamed. We had to stop production and all the raw materials were carefully cleaned again for a second time, extending the soaking time before granulation. The situation improved, but the particles were still foamed, causing all the forty tons of particles made from the raw materials on the site to have a slight foaming and strange smell. This reduced the sales price. When users went back to use, the wire drawing was easy to break. The smell is unpleasant and can only be mixed with other materials for use. Even the surface smoothness of injection molded products cannot be achieved! The result can be imagined!

A PE particle processing factory pulled the inner membrane of the raw material packaging bag from the chemical plant. After pulling it back for a few days, it was found that all the green grass around the area where the raw material was stored had died. They didn't pay attention and cleaned it, causing thousands of fish to turn white belly up. The consequences were very serious! Category 3: The processing plant is located by the river and has received over 10000 raw material bags from printing and dyeing factories. I thought it wouldn't have a big impact, but I didn't expect the pigments to be very strong. After four hours of cleaning, they slowly changed the color of the 100 meter river channel. The hotline for reporting the good deeds also led to the arrival of environmental testing personnel at the scene! When recycling raw materials, granulation manufacturers must pay attention to whether they can produce waste plastics that have irritating odors and packaging toxic and harmful chemical materials! Otherwise, it will cause serious environmental pollution and also result in losses! So, the handling of material recycling is very important.
