Recycling codes on productsRecycling codes are used to identify the materials out of which the item is made, to facilitate easier recycling process. The presence on an item of a recycling code, a chasing arrows logo, or a resin code, is not an automatic indicator that a material is recyclable; it is an explanation of what the item is made of. Codes have been developed for batteries, biomatter/organic material, glass, metals, paper, and plastics.[citation needed] Various countries have adopted different codes. For example, the table below shows the polymer resin (plastic) codes. In the United States there are fewer, because ABS is placed with "others" in group 7.
A number of countries have a finer-grained system with more recycling codes. For example, China's polymer identification system has seven different classifications of plastic, five different symbols for post-consumer paths, and 140 identification codes.[1] The lack of a code system in some countries has encouraged those who fabricate their own plastic products, such as RepRap and other prosumer 3-D printer users, to adopt a voluntary recycling code based on the more comprehensive Chinese system.[2]

The Standardization Administration of the People's Republic of China (SAC) has defined material codes for different types of plastics in the document GB 16288-2008. The numbers are consistent with RIC up to #6.[8]
Alternative recycling labels

The following recycling label projects are designed with the consumer in mind while SPI or Resin Identification Codes are designed to be recognized by waste sorting facilities. They provide an alternative that eliminates confusion as people often mistake any resin code to be recyclable, but this is not necessarily true. The recyclability of the numbers depends on the abilities of the facilities in the community.[9] Thus, they are not all automatically recyclable.
How2Recycle is a project that started in 2008.[10] The label provides information about the packaging material and clearly indicates whether it is recyclable, partially or totally. If it is not recyclable at all, it is shown by a diagonal line going through the recycling label.
On-Pack Recycling Label used in the UK.[11] It is very simple and only states whether it is recyclable or not.

Recycling PP5 plastic
PP plastic is recyclable, and the recycling process involves melting the plastic to create new products. The recycling process for PP is similar to that of other plastics, but it requires a different set of equipment and procedures due to its unique properties. PP can be recycled into a variety of products, such as garden furniture, bins, and crates.
Polypropylene, commonly known as PP5 plastic, is a thermoplastic polymer that is widely used in various applications due to its versatility and durability. This plastic is known for its strength, resistance to heat and chemicals, and flexibility, making it a popular choice for everything from food containers to car parts.
One of the most common uses of PP 5 plastic is in the production of food containers, as it is safe for both hot and cold food, and does not leach any harmful chemicals into the food it comes into contact with. It is also widely used in the production of household items such as kitchenware, storage containers, and cleaning supplies, as it is resistant to wear and tear and can be easily molded into different shapes and sizes.
Another significant use of PP #5 plastic is in the automotive industry. Due to its strength, heat resistance, and flexibility, it is used in the production of various car parts such as battery cases, fuel tanks, and door panels. This plastic is also used in the production of various medical devices, as it is biocompatible and can be easily sterilized, making it ideal for use in the healthcare industry.
One of the most impressive qualities of PP 5 plastic is its recyclability. PP 5 plastic is recyclable and can be melted down and re-molded into a new product, reducing waste and conserving resources.
Polypropylene is a sustainable packaging material due to being highly recyclable. PP has become a commonly used packaging material and a recycling infrastructure has been built out over the past 5 years making it the 3 rd most commonly recycled plastic from curbside, after PET and HDPE Bottles.
Examples of Polypropylene Plastic
PP plastic is used in a variety of products, from everyday items to specialized applications. Some examples of PP plastic products include:
Plastic vs. Polypropylene
While PP is a type of plastic, it differs from other plastics in several ways. PP plastic is considered a safe plastic number, as it does not contain bisphenol A (BPA) or other harmful chemicals. PP plastic is also more heat-resistant and durable than many other plastics, making it suitable for use in high-temperature applications.
However, PP plastic is not as widely recycled as some other plastics, such as PET (polyethylene terephthalate) and HDPE (high-density polyethylene). PET is commonly used in water and soda bottles, while HDPE is used in milk jugs and detergent containers. These plastics are more commonly accepted by recycling programs and can be recycled into a variety of products, such as new bottles, pipes, and toys.
