What You'll Learn
Plastic bottles and glass jars
Plastic bottles, including their caps, can be recycled in Raleigh. However, it is important to note that the process of recycling plastic is complex and often involves downcycling, where the plastic is turned into a lower-value product, such as shoes, instead of being recycled into a new plastic bottle. There have also been reports that plastic collected for recycling in the United States is sometimes burned or ends up in landfills instead of being properly recycled.
Glass jars are also accepted in Raleigh's recycling program. Glass is recycled by being extracted, cleaned, broken down, and sorted into shards. These shards are then melted down and molded into new items, such as jars, bottles, highway paint, fiberglass, and paint fillers. Glass recycling offers environmental benefits by reducing waste sent to landfills and helping glass manufacturers reduce emissions.
Overall, while plastic bottles and glass jars can be placed in Raleigh's recycling bins, it is important to understand the complexities and limitations of the recycling process, especially for plastics.

Plastic recycling process
Plastic recycling is a complex process that can be broadly broken down into the following steps: collection, sorting, washing, shredding, melting, and moulding.
Firstly, collectors from the government or private companies gather all post-consumer plastic materials from homes, schools, and other institutions. In Raleigh, North Carolina, this process begins with residents tossing their glass salsa jars, plastic laundry detergent containers, and paper junk mail into their blue or green recycling bins for collection.
The collected plastic materials are then sorted into different types of plastic. Sorting can be done manually or by machines at recycling plants, using optical sorting technology, including cameras and lasers, to detect recyclable materials and ensure they wind up in their like-item piles. The material is sorted into three streams: the intended plastic (high value), missorted plastic containers (medium value), and waste (negative value). Sorting is based on various factors such as chemical composition, colour, thickness, and intended end-use.
After sorting, the plastic undergoes a washing process to remove impurities, including product labels, adhesives, and food residue.
The cleaned plastic is then shredded or cut into small pieces called flakes. Shredding allows for the removal of additional impurities, such as metals.
Next, the plastic flakes are melted and processed into pellets or nurdles. The melting process involves placing the flakes in an extruder, where they are filtered to remove small solids.
Finally, the pellets or nurdles are moulded into new products.
It is important to note that not all plastics are recyclable. Some types of plastic, such as plastic bags, can be excluded from the recycling process as they pose a risk of clogging machinery and are deemed not worthwhile to recycle. Additionally, attempting to recycle plastics with food residue, chemicals, or adhesives can disrupt the process, often resulting in plastics being sent to landfills instead of being recycled.

Plastic not recycled
Raleigh, North Carolina, has a biweekly curbside recycling program that accepts plastics numbered 1 through 5 and number 7 (rinsed). However, there are reports that suggest plastic recycling in Raleigh may not be as effective as claimed. Some residents have expressed concerns that most of the plastic they recycle ends up being burned rather than recycled. This is a common issue in the United States, where a lot of "recyclable" plastics are burned for fuel or sent to developing countries, ending up in the ocean.
The process of recycling plastic is complex and often costly. While it is possible to downcycle plastic, it is not truly recyclable. When plastic bottles are recycled, they are usually turned into shoes or other products, not new bottles. Additionally, the optical sorting technology used in recycling plants may not correctly capture plastic lids, which can lead to further issues in the recycling process.
To address these concerns, the City of Raleigh recommends that residents discard plastic lids with their trash. The website also provides information on proper recycling practices and guidelines for what can and cannot be recycled. However, some residents have suggested that the restrictions on plastic recycling in Raleigh are quite high. For example, plastic clamshell containers are prohibited, while bottles and tubs are generally allowed unless they are on the prohibited list.
Given the challenges and restrictions associated with plastic recycling in Raleigh, it is important for residents to be mindful of their plastic consumption and disposal. While recycling can be a beneficial practice when done properly, it is not a cure-all solution to the plastic waste problem. Residents can also explore other sustainable practices, such as reusing and repurposing plastic items whenever possible. Additionally, supporting policies and initiatives that promote reduced plastic usage and encourage alternative materials can help mitigate the issues associated with plastic recycling.

Plastic numbered 1-5 and 7
Raleigh, North Carolina, accepts plastics numbered 1 through 5 and number 7 for recycling. However, it's important to note that these plastics should be rinsed before placing them in the recycling bin.
The city has made significant improvements to its curbside recycling program, with biweekly pick-ups using 95-gallon recycling bins or carts. Since the program began in 1989, Raleigh has recycled 300,000 tons of material.
The recycling process in Raleigh involves optical sorting technology, where cameras and lasers detect recyclable materials and direct them to the correct location in the plant. While this technology has improved the efficiency of the recycling process, it may not always correctly capture plastic lids, such as those on sour cream or cream cheese containers. In such cases, human sorters manually separate these lids to ensure they are sorted into the correct plastic category.
It's worth noting that some residents of Raleigh have expressed skepticism about plastic recycling, claiming that most plastic ends up being burned or sent to landfills instead of being properly recycled. However, the NC Department of Environmental Quality emphasizes the benefits of recycling, highlighting its positive impact on the local economy and the creation of private sector jobs.

Plastic container disposal
The city of Raleigh accepts plastics numbered 1 through 5 and number 7 for recycling, as long as they are rinsed. This includes plastic bottles and tubs unless they are on the prohibited list, such as plastic clamshell containers. The city's website also instructs residents to discard plastic lids with the trash, as the current optical sorting technology cannot capture them. However, it is important to note that even rinsed and sorted plastics may not always be recycled and can end up in landfills or burned for fuel.
To properly dispose of plastic containers in Raleigh, it is recommended to follow the city's recycling guidelines and only recycle accepted plastics. Rinsing and sorting plastics can improve their chances of being recycled. Additionally, residents can reduce plastic waste by reusing containers whenever possible or choosing alternative materials, such as metal or glass, which have higher recycling rates.
It is worth noting that some plastics may be recycled into different products, a process known as downcycling. For example, plastic bottles may be turned into shoes rather than new bottles. While this does not eliminate the need for new resources, it can extend the lifespan of the plastic and reduce the amount of virgin material required.
Finally, for plastics that cannot be recycled, residents can explore other disposal methods, such as repurposing or upcycling. Some companies may accept hard-to-recycle plastics for repurposing, or residents can get creative and find new uses for their plastic containers, such as using them for storage or crafting. While not ideal, if no other options are available, plastics can be disposed of in the trash, ensuring they are clean and dry to reduce potential hazards.
In summary, plastic container disposal in Raleigh involves following the city's recycling guidelines, understanding the limitations of plastic recycling, and exploring alternative disposal methods when possible. By taking these steps, residents can help reduce plastic waste and contribute to a more sustainable future.
