Plastic recycling can be difficult to determine, especially when it comes to the various types of plastics and their recyclability. Number 5 plastic, also known as polypropylene (PP), is one of the most commonly used plastics in packaging due to its lightweight, heat-resistant, and durable properties. Fortunately, the Phoenix area has a comprehensive recycling program that includes the number 5 plastic, allowing residents to properly dispose of their plastic waste and reduce their environmental impact.

What You'll Learn
Plastic #5 is also known as polypropylene (PP)
Polypropylene is favoured by manufacturers because it is lightweight and strong, but also offers excellent protection from moisture and chemicals. It is highly flexible and can retain its shape, even when bent or twisted. These qualities make it ideal for a wide range of applications, from food containers to car parts.
Plastic #5 is recyclable, and many curbside recycling programs accept it. However, it is important to check with local recycling guidelines, as some areas may have different rules. Both rigid and flexible forms of PP can be recycled, but the processes for each differ. Curbside programs often accept rigid plastic products like bottles or tubs, but not flexible PP like bags or soft packaging.
To identify Plastic #5, look for the number "5" or the letters "PP" inside the chasing arrows symbol on the item. When recycling plastic containers with caps, it is recommended to leave the caps on, as recycling technology has advanced to handle them. However, it is important to keep plastics containing food or drink out of hot places, as higher temperatures can cause the plastic to break down and release chemicals.

PP is widely recycled in Phoenix and Arizona
Plastic recycling can be challenging, and it can be difficult to determine which plastics can be recycled and which cannot. Typically, plastics labelled 1 and 2 are accepted for recycling, while plastics labelled 3 to 7 are not. However, in Phoenix, Arizona, plastics labelled 5, also known as polypropylene or PP, can be recycled as well.
PP is one of the most recycled plastic products in the post-consumer plastics market, although it still only recycles less than 1% of its packaging. It is widely used for packaging because it is light, heat-resistant, and strong. Yogurt containers are an example of PP, or plastic #5.
The Phoenix area has a comprehensive recycling program that includes this type of plastic. This is good news for environmentally conscious residents who want to ensure their plastic waste is being properly disposed of. The city has diverted approximately 130,000 tons of waste from its primary landfill.
In addition to PP, other plastics that are commonly recycled in Phoenix and Arizona include PETE (labelled 1), HDPE (labelled 2), PVC (labelled 3), LDPE (labelled 4), and PP (labelled 5 or 6).

PP is used in packaging due to its strength and heat-resistance
In Phoenix, most plastics are accepted for recycling, except for plastic film. However, only plastics marked 1, 2, or 5 are recycled, with the rest being sent to landfills. Polypropylene (PP) is a popular packaging material due to its lightweight, durable, and versatile nature. It is used in various industries, including food, beverages, cosmetics, household cleaning, and healthcare. PP's processing versatility allows it to be produced in different colours and formats, such as cups, trays, containers, and bottles. Its high chemical and moisture resistance, along with its thermal resistance, make it ideal for maintaining product integrity. Additionally, PP's tensile strength and flexibility enhance its popularity in packaging.
Polypropylene is a unique plastic with a wide range of applications. Its high resistance to chemicals, moisture, and corrosion makes it valuable in the healthcare and pharmaceutical industries. PP is also used in the automotive industry for parts such as battery casings, trays, and bumpers. The adaptability of PP is advantageous, as it can be produced through various techniques like injection moulding, extrusion, and mould blowing. This versatility results in its use in multiple industries and applications, from packaging to machinery parts and textiles.
The popularity of PP in packaging can be attributed to its strength and heat resistance. PP is known for its impressive tensile strength, which ensures that the packaged product remains intact. Its thermal resistance prevents discolouration and brittleness, maintaining the integrity of the package and its contents. Additionally, PP's ability to withstand twisting motions of up to 360 degrees without snapping enhances its durability and makes it a preferred choice for packaging.
While PP is widely used in packaging due to its favourable properties, its recovery and recycling pose challenges. The diversity in size, format, and colour of PP packages makes sorting and collecting them difficult. However, advancements in technology, such as near-infrared (NIR) scanning, optical sorters, robotics, and artificial intelligence, are improving the efficiency of PP sorting and recycling processes.

Plastic bags are not accepted in Phoenix's recycling bins
Phoenix, Arizona, accepts most plastics for recycling—except for plastic film. Plastic bags are one of the most common items mistakenly placed in the city's blue recycling bins. In 2014, an estimated 731 tons of plastic bags were found in Phoenix's recycling bins.
Plastic bags can get stuck in recycling equipment, causing repairs and interruptions to the recycling process. They can also lead to contamination, as workers do not have time to open trash bags filled with recyclables, resulting in entire bags being sent to landfills.
While plastic bags are not accepted in Phoenix's recycling bins, they can be recycled in special bins found near the entrance of many grocery stores. These bins are typically meant for plastic films or soft plastics, such as sandwich baggies, dry-cleaning bags, and trash bags. However, it is important to ensure that these bags are free from food or liquid residue before placing them in the designated grocery store bins.
To avoid contamination and reduce the city's recycling costs, it is important for Phoenix residents to remember not to place plastic bags in their curbside recycling bins. Instead, reusable containers or bags can be used to collect and dump loose recyclables directly into the blue bins.

Plastic #5 containers include yoghurt pots
Phoenix accepts almost all plastics for recycling, except for plastic film. However, due to a lack of demand, plastics that are not marked with a 1, 2, or 5 are often sent to landfills.
Plastic #5, also known as polypropylene, is a type of plastic resin that accounts for about 14% of plastic production in the US. It is used to make a variety of products, including yoghurt pots, tubs, bottles, and jars.
In the past, polypropylene has been difficult to recycle due to the presence of toxic additives and the challenge of sorting it from other plastics. According to data from the EPA, only 2.7% of polypropylene containers and packaging were recycled in 2018, with that number falling to 0.6% when including all forms of polypropylene.
However, recent developments have seen an increase in the recyclability of polypropylene. How2Recycle, an industry working group with members from major companies, now considers a wide range of polypropylene products to be "widely recyclable." This means that more than 60% of Americans are believed to have access to a recycling program that accepts these items. Despite this, there is scepticism from industry experts and environmental advocates, who argue that the actual recycling rate of polypropylene is much lower, and that the accessibility of recycling programs is a distraction from the real metric of the recycling rate.
