Plastic is everywhere, and it is cheap to make and profitable. However, only two of the seven types of plastic are recyclable, and a staggering 91% of plastic is not recycled. While many cities have recycling centers, the plastic waste that ends up in them is often not recycled and instead ends up in landfills or incinerated. This is due to various reasons, including contamination, a lack of infrastructure, and the economics of recycling. Some cities, like Chicago, have extremely low recycling rates, while others, like Oregon and Michigan, have had success with bottle bills that pay customers to bring back their plastic bottles. Additionally, homeless and marginalized individuals in some cities engage in guerilla recycling, where they collect and trade recyclables for a small income. Overall, the presence of recycling centers in a city does not guarantee that plastic will be repurposed, and there are numerous challenges to achieving high plastic recycling rates.

What You'll Learn
Plastic recycling rates
The reasons for the low recycling rates are varied. Firstly, not all plastics are recyclable. While 75% of global plastics are thermoplastics, which can be melted and moulded into new products, the remaining 25% are thermoset plastics that do not soften with heat and are therefore nearly impossible to recycle. Examples of products using thermoset plastics include electrical insulation, ropes, belts, and pipes.
Another issue is that plastic with food residues or other contaminants usually cannot be recycled. Only clean, high-quality plastics can be processed, and the washing process is often energy-intensive and costly. In addition, the low recycling rates of plastic are in contrast to other materials such as paper, which has a recycling rate of 66% in the US as of 2020.
The failure of plastic recycling is also due to the challenges in the recycling process itself. Recycling plastic is energy-intensive and becomes more costly with additional steps such as washing and sorting. As a result, recycled plastic becomes less economically viable compared to producing new plastic, which remains relatively cheap. Furthermore, incineration of plastic waste can be more profitable in countries with high electricity prices, contributing to air pollution and greenhouse gas emissions.
The recycling of plastic is also impacted by the global market. Previously, the US exported recyclables to China, which contributed to the recycling rates of plastic. However, with the loss of this market, the US recycling industry faced economic challenges, and municipalities had to pay more to recycle or discard the waste. This has further contributed to the low recycling rates of plastic.
Despite these low rates, there are some positive developments. Environmentalists and lawmakers in some US states are pushing for legislation banning single-use plastics and "bottle bills" that pay customers to return plastic bottles. These efforts have led to successful recycling rates in certain states, such as Oregon and Michigan, but they also face resistance from the plastic and oil industry lobbyists.
Overall, the plastic recycling rates are extremely low, and the issues are multifaceted, requiring a range of solutions to address the global plastic pollution crisis effectively.

Challenges to recycling plastic
Plastic recycling is a complex process that involves multiple stakeholders, including consumers, waste pickers, manufacturers, suppliers, governments, and the private sector. However, despite the efforts to recycle plastic, several challenges hinder the effectiveness of these processes.
One of the primary challenges is the variety of plastic types, with hundreds of different kinds of plastics, each with unique properties, such as colour, shape, structure, and melting point. This complexity necessitates sorting plastics into distinct categories to maintain their purity. However, due to a lack of awareness and proper industrial experience, different types of plastics are often combined in manufacturing, making recycling extremely difficult. Consequently, many plastics end up being incinerated or landfilled, resulting in a waste of valuable resources.
Another significant challenge is the contamination of plastics with food or oil residues, rendering them unfit for recycling. Only clean, high-quality plastics are suitable for the recycling process, and the washing process required to clean contaminated plastics adds costs and energy intensity to the recycling process. Furthermore, the economics of recycling can be challenging, as the recycled material often needs to be sold to recoup the costs of collection and transportation.
The global demand for plastics continues to rise, driven by the material's favourable production economics, barrier properties, lightweight nature, and malleability. This high demand results in a significant amount of plastic waste, which, if not properly managed, can leak into the environment, especially oceans near coastal cities. The solution lies in creating circularity for plastics, but this requires significant funding and collaboration between various entities, including governments and the private sector.
Additionally, the recycling process is hindered by the lack of standardised waste management systems across different regions. In some areas, waste collection is privatised, requiring households to pay for their waste to be collected, which can lead to dumping or burning of waste when people refuse to pay. Moreover, the low landfill fees in certain regions further discourage recycling, as it is much cheaper to dump waste than to recycle it.
To overcome these challenges, it is essential to educate consumers, waste pickers, and manufacturers about the different categories of plastics and their specific properties. Additionally, providing training and guidance on product design and waste sorting can help separate and recycle end-of-life plastic products more effectively.

Plastic waste management
The complex nature of plastics poses significant challenges to recycling. Thermoplastics, which make up 75% of global plastic production, can be melted and molded multiple times, making them, in theory, recyclable. However, in practice, food residues and other contaminants often render them unfit for the recycling process. Only good-quality, clean plastics are suitable for recycling, and the process itself is energy-intensive and costly. As a result, many recycling facilities opt for cheaper alternatives, such as landfilling or incineration, which have detrimental effects on the environment.
To improve plastic waste management, a holistic approach is necessary. Firstly, reducing plastic waste generation is crucial. This can be achieved through legislation banning single-use plastics and promoting reusable alternatives. Secondly, improving waste collection and disposal systems is essential. The Basel Convention provides guidance for better management, and countries should invest in developing controlled disposal services and regular waste collection for all. Additionally, public education plays a vital role in ensuring that individuals understand the importance of proper waste segregation and the limitations of recycling certain plastics.
Furthermore, the economics of recycling must be addressed. The recycling industry has faced challenges due to the loss of the Chinese market, and facilities struggle to recoup costs without a market for recycled materials. Governments can play a role in incentivizing recycling by providing subsidies or implementing policies that encourage the use of recycled materials. Finally, collaboration between industries is key. Oil and gas industry lobbyists, for instance, have faced criticism for their resistance to "bottle bills" that incentivize customers to return plastic bottles for recycling. A unified effort is required to transition to a more sustainable model, where plastic is reused and recycled into new products.
In conclusion, plastic waste management demands immediate attention to mitigate the growing plastic pollution crisis. By reducing plastic waste generation, improving collection and disposal systems, addressing economic challenges, and fostering collaboration between various sectors, we can move towards a more sustainable future.

Plastic repurposing methods
Plastic is a significant contributor to environmental pollution, with 91% of plastic not being recycled. The reasons behind the low recycling rates are numerous, including the fact that not all plastics can be recycled due to their material properties. Additionally, plastic with food residues is usually deemed unfit for recycling, and the recycling process is energy-intensive and costly. Despite these challenges, there are methods to repurpose plastic and keep it out of oceans and the environment.
One method is to reuse plastic items for alternative purposes. For example, plastic takeout containers can be used to store receipts or other small items, while plastic bags can be fused together with parchment paper and an iron to create rugs or placemats. Plastic bottles can be reused as watering cans, storage for paint or other liquids, or even as a simple DIY bird feeder.
Another method is to recycle plastic through dedicated facilities. However, it is important to note that the success of this method depends on the availability and accessibility of such facilities, as well as the proper sorting and cleaning of the plastic waste. According to a Greenpeace report, only 5% of plastic accepted by recycling facilities in the U.S. is actually repurposed, with the rest ending up in landfills.
To address the plastic waste crisis, a combination of individual actions and systemic changes is necessary. Individuals can reduce their plastic consumption, particularly single-use plastics, and properly dispose of or repurpose the plastic items they already have. On a larger scale, legislation banning single-use plastics and incentivizing plastic recycling, such as "bottle bills," can help increase recycling rates. Additionally, switching to systems of reuse and refill, as well as investing in new technologies for recycling and repurposing plastic, can contribute to a more sustainable future.
Overall, by implementing a range of plastic repurposing methods and addressing the challenges associated with plastic recycling, we can work towards reducing plastic pollution and protecting the environment.

City-specific recycling programs
While there is no standard recycling program that applies to all cities, there are some common strategies that can be implemented to improve plastic recycling rates.
One strategy is to establish a Plastic Credit System, which requires producers to purchase recycling certificates based on the amount of plastic waste recycled. This approach not only incentivizes the recycling of plastic waste but also holds producers accountable for their contribution to plastic waste. Additionally, cities can focus on implementing activities outlined in the City Action Plan, such as adopting new policies, engaging key stakeholders, improving waste infrastructure, and encouraging innovation. For instance, the City of Philadelphia provides information to its residents about what goes into recycling bins, helping to ensure that only acceptable materials are placed in the bins.
Another successful strategy has been the implementation of "bottle bills," which pay customers to return their plastic bottles. This approach has led to higher recycling rates for plastic bottles in certain states, such as Oregon and Michigan. However, it is important to note that these bills have faced resistance from the plastic and oil industry lobbyists. Environmentalists and lawmakers in some states are pushing for similar legislation to ban single-use plastics and promote systems of reuse and refill.
It is worth noting that the recycling landscape has changed significantly due to the absence of the Chinese market for plastic and other recyclables. This shift has disrupted the economics of the recycling industry, with processing facilities and municipalities facing increased costs for recycling or opting to discard the waste altogether. As a result, there is a growing emphasis on improving waste management capacity, including collection, separation, and recycling infrastructure, to effectively address the unique challenges faced by each city.
While recycling is an important part of reducing plastic waste, it is not the sole solution. Other strategies, such as reusing and refilling containers, can also play a significant role in mitigating plastic pollution. Additionally, public education is crucial in ensuring that only acceptable materials are placed in recycling bins, as contamination can render otherwise recyclable materials unfit for recycling.
