Turning Pollution Into Treasure: Reuse And Innovation

Plastic pollution is a pressing issue, with over 10 billion metric tons of plastic produced globally to date. While recycling is often touted as the solution, it is not always effective, and recycled plastic can even be more toxic than its virgin constituents. The process of recycling plastic can increase its toxicity, and the plastic recycling infrastructure can cause air, soil, and water pollution. With less than 9% of plastic ever recycled, it is clear that other solutions are needed. Prioritizing reduction and reuse are the most effective ways to save natural resources, protect the environment, and save money. By focusing on plastic-free reuse, we can end wastefulness at the source and create a healthier planet for future generations.

Plastic recycling's limitations

Plastic recycling helps keep disposable products out of landfills, where they would take hundreds of years to decompose naturally. However, it has its limitations.

Firstly, unlike other materials like glass and metal, plastic cannot continually serve the same purpose after being recycled. Recycled plastic is often downcycled, meaning it becomes a different, less useful product. For example, a plastic water bottle may be downcycled into artificial turf or plastic furniture. After downcycling, plastic typically cannot be recycled again and ends up in a landfill despite having seen a secondary use.

Secondly, the process of melting down and recycling plastic produces volatile organic compounds (VOCs), which are fumes that can harm plant and animal life near the industrial site. The heat needed to melt plastic also generates carbon emissions, contributing to global warming. Additionally, the same VOCs that harm the environment can also present health threats to people who come into contact with recycled plastics. Plastic resin, which is part of the manufacturing and recycling process, can leech into foods stored in recycled plastic containers, potentially increasing the amount of chemicals consumed by users.

Another limitation of plastic recycling is the challenge of sorting and separating different types of plastics. Most plastic waste consists of multiple layers and components, making it difficult to recycle. For example, a small amount of PVC contaminant in a PET recycle stream will degrade the recycled PET resin due to the evolution of hydrochloric acid gas from the PVC at higher temperatures.

Furthermore, the economic viability of plastic recycling is influenced by the price of recycled polymer compared to virgin polymer and the cost of recycling compared to alternative disposal methods. The quality of recovered plastic is typically lower than that of virgin plastic, and the price of virgin plastic sets the ceiling for prices of recovered plastic. Technological advances in recycling can improve economics by decreasing costs and increasing the value of recycled resin.

Reuse as a solution

Reuse is a critical part of the waste management hierarchy, which ranks waste management strategies from most to least environmentally preferred. According to the US Environmental Protection Agency (EPA), source reduction and the reuse of waste materials are the most preferred strategies, followed by recycling.

Reuse is an effective way to reduce waste, as it prevents the need to create new products, which in turn reduces greenhouse gas emissions, saves natural resources, protects the environment, and saves money. By reusing items, we can also reduce the amount of waste that ends up in landfills and incinerators, which helps to reduce pollution and its harmful effects.

There are several ways to incorporate reuse into our daily lives. For example, we can repair and maintain clothing, appliances, and other items instead of frequently replacing them. We can also borrow, rent, or share items that are used infrequently, such as party decorations, tools, or furniture. Donating unwanted items to local charities, community centers, thrift stores, or schools is another excellent way to ensure that others can reuse them, preventing usable goods from going into landfills.

When it comes to plastic, in particular, the concept of "plastic circularity" or the idea that plastics can be reused endlessly, has been perpetuated by the plastic and fossil fuel industries. However, it is important to note that plastic recycling often involves downcycling, where plastic is turned into items of lesser value and quality, and it can lead to increased toxicity and pollution. Therefore, it is crucial to prioritize reuse and reduction over single-use plastics, reducing the need for recycling altogether.

By focusing on reuse, we can tap into a solution that ends wastefulness at its source, reducing the environmental and health impacts associated with both the creation and disposal of waste.

The recycling process

Firstly, collection and processing involve businesses, consumers, and either private or government entities. Recyclables are collected through methods such as curbside collection, drop-off centres, and deposit or refund programs. They are then sent to recovery facilities to be sorted, cleaned, and processed into materials usable in manufacturing. The recyclables market is subject to supply and demand, with prices fluctuating accordingly.

The second step is manufacturing, where the processed recyclables are made into new products at recycling plants or similar facilities. Recycled materials are increasingly being used in innovative ways, such as recovered glass in asphalt for road paving or recovered plastic in carpeting and park benches.

The third and final step is purchasing new products made from recycled materials. Buying such products helps close the recycling loop and encourages the creation of a closed-loop system, where materials are reused, recycled, or repurposed.

While recycling is beneficial, it is not without its drawbacks. It can be expensive due to the need for specialised equipment and infrastructure. Contamination is another issue, as non-recyclable materials mixed with recyclables can render entire batches unusable. Additionally, recycling certain materials, such as paper and plastic, can require chemicals, large amounts of water and energy, and release harmful pollutants.

Despite these challenges, recycling remains crucial in reducing waste and promoting sustainability. It conserves natural resources, reduces greenhouse gas emissions, improves air and water quality, and provides economic benefits. However, it is essential to focus on reducing contamination, improving infrastructure, and exploring other waste reduction strategies to enhance the effectiveness of the recycling process.

The environmental impact of recycling

Recycling has a significant environmental impact, offering both benefits and challenges.

Benefits of Recycling

Recycling is the process of collecting and processing materials that would otherwise be discarded as trash and turning them into new products. This process offers several advantages over creating new products from raw materials. Firstly, it conserves natural resources by reducing the need to extract resources such as timber, water, and minerals. Recycling also helps combat climate change by reducing greenhouse gas emissions. According to the US EPA, recycling and composting of municipal solid waste saved over 193 million metric tons of carbon dioxide equivalent in 2018. Recycling certain materials, such as aluminum, is incredibly energy-efficient. Using aluminum scraps to produce aluminum cans, for example, saves 95% of the energy used when creating cans from raw materials.

Recycling also reduces waste and pollution by diverting trash away from landfills and incinerators, which in turn reduces the harmful effects of pollution and emissions. Recycling can also provide economic benefits, such as creating jobs, generating tax revenues, and reducing costs associated with waste management.

Challenges of Recycling

Despite its benefits, recycling faces several challenges. One significant issue is the confusion surrounding the recycling process, with many people unsure about what items can be recycled, where, and how. This confusion often leads to recyclables ending up in the trash and trash being placed in recycling bins. Additionally, America's recycling infrastructure has struggled to keep up with the evolving waste stream, and there is a need for improved communication between manufacturers and the recycling industry to effectively manage the recycling of new materials.

Another challenge lies in the domestic markets for recycled materials, which need to be strengthened. Historically, the US has exported some recycled materials internationally, but changing international policies have restricted this practice. Furthermore, integrating recycled materials and end-of-life management into product and packaging designs remains a hurdle, as does the development of consistent measurement methodologies to improve the recycling system's performance.

Overall Impact

Recycling has a positive environmental impact by reducing waste, conserving resources, and mitigating climate change. However, the challenges faced by the recycling industry, such as infrastructure gaps and market limitations, need to be addressed to maximize its benefits.

The economic impact of recycling

Recycling has a significant positive impact on the economy, as well as the environment. It is a critical part of the US economy, contributing to jobs, wages, and government tax revenue. In 2012, recycling and reuse activities in the United States accounted for 681,000 jobs and $37.8 billion in wages. This equates to 1.17 jobs for every 1,000 tons of materials recycled. The recycling industry also generated $5.5 billion in tax revenues.

Recycling can lower production costs by reducing energy costs by up to 95%. This can help to offset the costs of recycling. Recycling also supports economic justice by reducing the negative impact of landfill sites and natural resource extraction on low-income communities and communities of color.

The economic benefits of recycling are closely tied to its environmental benefits. Recycling reduces the need for new materials made from natural resources, which lowers the amount of air and water pollution created in extraction and production processes. It also reduces the amount of waste sent to landfills and incinerators, helping to create a healthier and more sustainable environment for communities.

Recycling also encourages us to be mindful of our resource consumption and trash creation. By reducing both, we can improve our local and global environment and conserve natural resources for future generations.
