7 Plastic Sorting: Techniques to separate 7 plastic from other recyclables

The process of sorting and recycling 7 plastic, also known as polypropylene (PP), can be a crucial step in waste management, especially in cities like Chicago, which has specific guidelines for plastic recycling. This type of plastic is commonly found in food containers, bottle caps, and various household items. Proper sorting techniques are essential to ensure that 7 plastic is recycled effectively and does not contaminate other recyclable materials. Here are some methods and strategies to separate 7 plastic from the rest:

Visual Inspection and Sorting: One of the primary techniques is visual identification. 7 plastic is typically clear or slightly translucent, which helps in distinguishing it from other plastics like PET (polyethylene terephthalate) or HDPE (high-density polyethylene). Train waste sorters to look for this characteristic and separate 7 plastic items from the general waste stream. This method is simple yet effective for initial sorting.

Density Separation: 7 plastic has a unique density, which can be utilized for separation. It is less dense than many other plastics, including PET and HDPE. Using a technique called 'floatation' or 'density separation,' operators can place the mixed plastics in water or a liquid solution. 7 plastic will float to the top, allowing for easy collection and separation from denser plastics. This method is particularly useful in large-scale recycling facilities.

Near-Infrared (NIR) Sorting: Advanced recycling centers employ near-infrared spectroscopy technology. NIR systems can identify different types of plastics based on their molecular structure. When a mixed stream of plastics is fed into the NIR sorter, it emits a specific wavelength of light that is absorbed differently by various plastics. 7 plastic has a unique absorption pattern, allowing the machine to sort it accurately. This technology ensures high-precision sorting and is widely used in automated recycling systems.

Manual Sorting with Training: In some cases, especially in community recycling programs, manual sorting is common. Train volunteers or staff to recognize 7 plastic and its unique properties. This can include teaching them about the material's flexibility, feel, and appearance. With proper training, individuals can effectively separate 7 plastic from other recyclables, ensuring it goes to the right recycling stream.

Education and Awareness: Educating the public about the importance of proper plastic sorting is vital. Chicago's recycling program can provide guidelines and resources to residents, explaining the benefits of separating 7 plastic. This awareness campaign can encourage better recycling practices and reduce contamination in the recycling stream.
