Clear Plastic Packaging: Is It Recyclable?

Plastic packaging is a major contributor to the world's plastic waste problem. While some plastic packaging is technically recyclable, it is often not recycled due to various challenges in the recycling process. For example, certain types of plastic packaging, such as clamshells, are not collected by existing material recovery facilities, making it difficult to sort and recycle them. Additionally, the variety and abundance of plastic packaging create complications for the recycling industry. Clear plastic packaging, in particular, may face similar issues in the recycling stream. Understanding the recyclability of clear plastic packaging and exploring alternatives are crucial steps towards reducing plastic waste and promoting environmental sustainability.

Clamshell packaging is recyclable but rarely recycled

The recycling process typically involves sorting plastics by type and shape at a material recovery facility (MRF). However, clamshells are often made of multiple types of plastic, with different parts made of different plastics. For example, the shiny adhesive labels are one plastic, while the protective cap is another. This makes it challenging for recyclers to process and sell these materials to companies that prefer a single type of plastic for manufacturing.

Additionally, clamshells are often contaminated with food residues or other materials, making them less desirable for recycling. They also break into different-sized chips than plastic bottles, melt at a different temperature, and have strong adhesives that are difficult to remove. As a result, recyclers cannot simply mix clamshells and plastic bottles together. Instead, they prefer to handle mostly or only #1 PET bottles, as they produce a relatively pure end product.

The demand for recycled PET content is high, especially in the food industry. However, the existing infrastructure for collecting and sorting clamshells is lacking. Clamshells are not always collected, and even when they are, many MRFs cannot sort them effectively from other materials. This results in a limited supply of recycled clamshells, which can drive up the price.

To address this issue, some companies are taking initiatives to improve the recyclability of clamshells. For example, Ridwell, a company in the US, has partnered with Green Impact Plastics to responsibly recycle clamshells from their members in Portland, Seattle, and South Puget Sound. Consumers can also play a role by avoiding products with plastic clamshell packaging and contacting manufacturers to express their concerns and encourage the use of more sustainable packaging.

Plastic bags are not recyclable and contaminate other materials

Plastic bags are a major source of environmental pollution, with a significant amount of plastic waste ending up in landfills and the ocean. In 2015, about 730,000 tons of plastic bags, sacks, and wraps were generated in the United States, and more than 87% of these items were never recycled. The problem is further exacerbated by the fact that plastic bags can take up to 1,000 years to degrade in a landfill, breaking down into microplastics that continue to pollute the environment and harm marine life.

Plastic bags are not recyclable in most curbside recycling programs and should not be used to separate materials in residential bins. When placed in recycling bins, plastic bags can clog machinery, tangle in sorting equipment, and contaminate other recyclable materials, leading to increased waste and higher costs for recycling centers. Additionally, when people place recyclable items in a plastic bag, it becomes challenging for workers at recycling facilities to identify and sort the contents, often resulting in the bagged items being sent directly to landfills.

The issue of plastic bag waste has gained significant attention, with states like California taking the lead in addressing the problem. In 2014, California became the first state to ban plastic bags, and as of March 2018, 311 local bag ordinances had been adopted across 24 states, including Hawaii. However, despite these efforts, plastic bags remain a significant contaminant in the recycling process, and public education campaigns, such as \"Recycle Right,\" are being implemented to address this issue.

To reduce the impact of plastic bags on the environment, it is essential to avoid using them whenever possible and to dispose of them properly. Reusable bags are a more sustainable alternative, and by regularly washing and drying them, individuals can minimize their environmental footprint. Additionally, it is crucial to separate recyclable items from plastic bags, ensuring that they are not placed in the same bin. By following proper disposal guidelines, individuals can play a crucial role in mitigating the harmful effects of plastic bags on the environment and improving the efficiency of the recycling process.

Plastic waste is often incinerated, creating greenhouse gas emissions

Clear plastic packaging, such as blister packs and clamshells, can be made from a variety of plastics, including PET (Polyethylene terephthalate). While technically recyclable, the recycling rate for plastic is low, with less than 9% of plastic being recycled in the US. This is due to a variety of reasons, including the fact that clamshells are not always collected for recycling and, when they are, they can be difficult to sort and separate from other materials.

Now, addressing the statement: "Plastic waste is often incinerated, creating greenhouse gas emissions."

Plastic waste is commonly incinerated, and this process releases greenhouse gases, contributing to climate change. According to the Center for International Environmental Law's (CIEL) report "Plastic & Climate: The Hidden Costs of a Plastic Planet", plastic emits greenhouse gases at every stage of its lifecycle, including waste management. The report highlights that incineration, or burning, of plastic waste is a significant contributor to these emissions.

Incineration facilities are often built near communities of color and low-income populations, disproportionately impacting these communities with pollution. The emissions from incinerating plastic waste are substantial, with the US alone releasing 5.9 million metric tons of carbon dioxide equivalent in 2015, according to the CIEL report. If plastic production and incineration continue to increase as predicted, greenhouse gas emissions will reach 49 million metric tons by 2030 and a staggering 91 million metric tons by 2050.

The production of plastic is closely tied to the fossil fuel industry, as plastic is derived from fossil fuels. As a result, the refining and manufacturing of plastic are also greenhouse-gas-intensive processes. The CIEL report emphasizes that the best path to reduce emissions is to transition toward a "zero-waste" approach, which prioritizes responsible production, consumption, reuse, and recovery of materials without incineration or landfilling.

To summarize, plastic waste incineration is a significant contributor to greenhouse gas emissions, and with the projected increase in plastic production and incineration, the environmental impact is expected to worsen. Therefore, it is essential to explore alternative waste management strategies and reduce plastic consumption to mitigate the climate impact of plastic waste.

Plastic packaging is a major challenge for the recycling industry

Single-use plastic packaging, such as clamshells, is a prime example of the challenges faced by the recycling industry. Clamshells are made from two identical plastic "shells" that hinge together to form a seal around a product. While clamshells are typically made from PET (Polyethylene terephthalate) plastic, which is highly recyclable, they are often not recycled due to collection and sorting issues. Many material recovery facilities are unable to sort clamshells from other materials, and even when they can be sorted, sticky labels and food residues can be difficult to remove.

The recycling process is further complicated by the fact that many plastic packages are made from multiple types of plastic. For example, containers may have shiny adhesive labels made from one type of plastic, while the protective cap is made from another. This mix of plastic types makes it difficult for recyclers to sell the recycled material to companies that prefer single-type plastics for manufacturing. As a result, much of this plastic waste ends up being burned to generate energy, contributing to greenhouse gas emissions.

The e-commerce industry's extensive use of plastic packaging further exacerbates the problem. With the ever-increasing popularity of online shopping, the amount of plastic packaging is estimated to double by 2025. Despite efforts by some companies to reduce plastic packaging, such as Amazon's waste-efficient packaging standards, the overall trend is towards greater plastic packaging usage in the e-commerce sector.

To address these challenges, various initiatives and legislation have been proposed. For instance, California has introduced a set of bills known as the Circular Economy Package, which aims to reduce single-use plastics and make it easier for consumers to identify recyclable materials. Additionally, Senate Bill 54 requires most single-use plastic packaging to be reusable, compostable, refillable, or recyclable by 2032. These efforts reflect a growing recognition of the need to transition towards a more sustainable and circular economy.

Plastic recycling labels aim to clarify recyclability for consumers

Plastic packaging is a major contributor to global plastic pollution, with the average American generating more than 250 pounds of plastic waste each year, much of which comes from packaging. While some plastic packaging is recyclable, the variety and abundance of plastic packaging pose significant challenges for the recycling industry. For instance, clamshells, a common type of plastic packaging, are often not recycled due to collection issues and the difficulty of sorting them from other materials.

To address these challenges, various initiatives are being implemented to improve plastic packaging recyclability and provide clear recycling instructions to consumers. One such initiative is the How2Recycle label, created by the Sustainable Packaging Coalition and GreenBlue, a recycling non-profit. This label aims to provide transparent and consistent on-pack disposal information to consumers in the US and Canada, helping them understand how to recycle or dispose of different types of packaging materials.

The How2Recycle label offers several benefits. Firstly, it provides special instructions for effectively recycling materials. Secondly, it communicates the recyclability designation, indicating whether a package is widely recyclable, requires a store drop-off, or is not yet recyclable. Thirdly, it identifies the type of packaging material, helping consumers understand which component the label refers to. Lastly, it provides specific disposal instructions for each packaging component.

In addition to the How2Recycle label, other efforts are being made to enhance plastic packaging recyclability and labelling. For example, the Government of Canada is working on regulatory frameworks for plastic packaging, including recycled content requirements and labelling rules for recyclability and compostability. These frameworks aim to improve the recycling outcomes of single-use and short-lived packaging products. Similarly, California has passed legislation requiring most single-use plastic packaging to be reusable, compostable, refillable, or recyclable by 2032, with definitions of "recyclable" to be set by the state agency CalRecycle.

While these initiatives are a step in the right direction, there is still room for improvement. Research by Consumers International, UNEP, and One Planet Network found that only 19% of assessed labels provided consumers with quality information to make informed recycling and purchasing decisions. This highlights the need for standardized and accessible labelling that enables consumers to make sustainable choices easily. A global, multi-stakeholder approach is crucial to tackling the plastic waste crisis and ensuring a sustainable future.
