Recycled Material

Recycled plastic material refers to the process of collecting and reprocessing discarded plastic products into raw materials that can be used again for producing new plastic products. The discarded plastic products are first collected and undergo sorting and separation. After cleaning and processing, impurities and contaminants are removed. This includes removing labels, tapes, metal components, etc., and using water and chemicals for cleaning to ensure the quality and safety of the plastic. The cleaned plastic is then fed into a shredder to be crushed and fragmented into pieces. This helps improve the processability and mixability of the recycled material for subsequent processing and manufacturing. The shredded plastic fragments are fed into a melting machine, heated, and melted into a liquid state. Through a specific pelletizing process, the melted plastic is cooled and transformed into small granules, which are known as recycled pellets or regrind. These recycled granules can be used for manufacturing various new plastic products. They can be mixed with new plastic granules to obtain the desired specific performance and quality.

Marine Debris

Marine debris refers to various waste and garbage present in the marine environment, including plastics, metals, glass, paper, wood, rubber, textiles, chemicals, and organic matter, among others. Among them, plastic waste is a major component of marine debris, including plastic bags, bottles, containers, floating objects, and fishing nets. However, marine debris can be part of a circular economy, taking fishing nets as an example. Firstly, the discarded or damaged fishing nets are collected and undergo sorting and processing, separating different types of fishing nets such as nylon, polyethylene (PE), etc., and they are cleaned, removing any attachments, and undergoing further processing. Through a melting process, the fishing nets are transformed into recycled plastic materials to be used for manufacturing new plastic products.
