What You'll Learn
Plastic waste journey
The journey of plastic waste is a long and complex process, and it is important to understand this journey to effectively reduce plastic waste. The first step in ensuring plastic waste does not end up in the ocean, landfill, or incineration facility is to understand which types of plastic can be recycled. Some common types of recyclable plastic include PET, HDPE, LDPE, and PP. The numbers on plastic products are used by the industry to indicate the type of plastic and do not signify whether it can be recycled in your local program.
Once you have determined which plastics can be recycled, the next step is to sort and separate them. This is important to prevent contamination, which occurs when non-recyclable materials mix with recyclable plastic. After sorting, the plastic waste is collected and transported to a recycling center. Some local recycling centers may accept certain types of plastic, while others may have different specifications, so it is important to research the facilities available in your area.
At the recycling center, the plastic waste is processed and recycled into pellets or flakes, known as feedstock. These feedstocks are then sold to manufacturers and given a new life as products or packaging. However, it is important to note that only about 9% of the world's plastic has been recycled, with the rest remaining as waste, causing harm to our seas and ecosystems.
In some cases, plastic waste is exported to other countries for recycling. This has led to concerns about the mismanagement of plastic waste, especially in developing nations. Additionally, some plastic waste may end up in landfills, which can pose threats to our ecosystem due to the toxic liquid called leachate formed during the decomposition process.
To ensure your plastic waste is recycled properly, it is essential to educate yourself and others about the effects of mismanaged plastic waste. Additionally, you can calculate your plastic footprint and take steps to reduce waste and improve recycling efforts.

Landfills
However, landfills are not a perfect solution for plastic waste. Plastic can easily get blown away and escape from the dumping site, especially in areas with poor waste management practices. This means that plastic in landfills can still end up in the environment and pose risks similar to littered plastic. Additionally, during the decomposition process of plastic and other solid waste, a highly toxic liquid called leachate is formed, which can leak into the environment during rainfall and contaminate soil and groundwater.
In recent years, there has been growing concern about the amount of plastic ending up in landfills. A Greenpeace report found that much of the plastic put into recycling bins is ultimately sent to landfills. This is due in part to the fact that recycling plastic is often not economically viable, and new plastic is typically cheaper than recycled plastic. As a result, companies are incentivized to choose new plastic over recycled alternatives.
The issue is further complicated by the fact that many countries, particularly low-income nations, receive large quantities of recycling waste from more developed nations. However, due to the sheer volume of waste and the lack of financial incentive, this waste often ends up being burned, landfilled, or dumped into the environment instead of being properly recycled.
Furthermore, it has been revealed that the oil and gas industry, which produces plastic, has long been aware that plastic cannot be economically recycled on a large scale. Despite this knowledge, these companies have continued to promote the idea of recycling to sell more plastic. As a result, the public has been misled into believing that their plastic waste is being recycled when, in reality, a significant portion of it ends up in landfills.

Plastic recycling centres
The process within a plastic recycling centre typically involves sorting and processing the incoming plastic waste. Some centres may have specific types of plastic they accept, such as PET (Polyethylene Terephthalate), commonly used for water bottles and food containers, or HDPE (High-Density Polyethylene) and LDPE (Low-Density Polyethylene), which are flexible plastics used in packaging. It is important to check with your local recycling centre to understand the types of plastic they can process.
Once sorted, the plastic waste is then processed and recycled into feedstock, typically in the form of pellets or flakes. These pellets are sold to manufacturers as raw material for creating new products. For example, plastic pellets can be used to create synthetic lumber for decking or park benches, or they can be recycled into new plastic films, pouches, or bags. This process keeps plastic out of landfills, incineration facilities, and the ocean, protecting our ecosystems from the harmful effects of plastic waste.
However, it is important to note that not all plastic waste ends up in recycling centres. Unfortunately, a significant portion of plastic waste still ends up in landfills, where it can escape the dumping site, especially in areas with poor waste management practices. Additionally, the recycling industry has faced challenges, with some developed nations exporting their waste to other countries, overwhelming poorer nations with inadequate waste management infrastructure. This has led to concerns about the social and environmental impact of the global waste trade, highlighting the importance of responsible waste management and the need for improved recycling practices worldwide.

Plastic waste exports
In the past, countries like the United States have been known to ship their plastic waste overseas, often to countries with poor waste management practices. This has resulted in the improper disposal of plastic, causing harm to the environment and local communities. A notable example is the case of Vietnam, where American plastic waste has ended up in landfills and caused pollution.
To address these issues, measures such as the Basel Convention Plastic Waste Amendments have been implemented to restrict exports of plastic waste. The University of Georgia researcher, Jenna Jambeck, also found that some countries, like Malaysia, Indonesia, and Vietnam, mismanaged a significant portion of their plastic waste. This further highlights the need for better regulation and accountability in the plastic waste trade.
Despite these efforts, the plastic waste trade continues, with countries like India exporting to over 111 countries globally. The complex nature of the trade, involving numerous suppliers, buyers, and countries, makes it challenging to ensure proper disposal and recycling. However, initiatives like Volza's India Export data provide comprehensive information on plastic waste exports, including shipment dates, countries of origin and destination, and supplier and buyer details.
To effectively reduce the negative impacts of plastic waste exports, a multi-pronged approach is necessary. This includes improving waste management practices in recipient countries, ensuring traceability and accountability in the plastic waste trade, and promoting domestic recycling and waste reduction initiatives. By addressing these issues, we can work towards minimizing the social and environmental harms caused by plastic waste exports.

Plastic waste reduction
Plastic waste is a pressing issue, with plastic ending up in landfills, incineration facilities, and oceans, causing harm to the environment and ecosystems. To address this, it is essential to focus on reducing plastic waste and improving recycling efforts. Here are some ways to achieve plastic waste reduction:
Reduce Plastic Consumption
The first step towards reducing plastic waste is to minimize the use of plastic, especially single-use plastic items. Opt for reusable alternatives whenever possible. For example, instead of using plastic bags, bring your own reusable cloth bags for shopping. Carry a reusable water bottle instead of buying bottled water, and use cloth napkins and reusable dishes, glasses, and cutlery. Avoid products with excessive packaging, and choose items with minimal or recyclable packaging.
Reuse and Repurpose
Reuse and repurpose plastic items whenever possible. For instance, reuse plastic containers, bottles, and bags instead of discarding them after a single use. Donate or sell unwanted plastic items that are still in good condition, so others can reuse them as well.
Recycle Responsibly
Recycling is an important part of reducing plastic waste. Learn about the types of plastic that can be recycled in your area and separate them accordingly. Some common recyclable plastics include PET (Polyethylene Terephthalate), used for water bottles and food containers, HDPE (High-Density Polyethylene), LDPE (Low-Density Polyethylene), and PP (Polypropylene). Check with your local recycling program to understand their specific guidelines and accepted materials. Additionally, look into how to recycle plastic bags, wrap, and film in your area, as these often require special handling.
Support Recycled Products
When purchasing products, choose those made from recycled plastic materials. This helps create a demand for recycled plastic and encourages the reuse of plastic waste. Look for products with recycled content, such as bubble wrap containing recycled plastic or furniture made from recycled plastic pellets.
Educate and Advocate
Education is a powerful tool in the fight against plastic waste. Learn about the impact of plastic pollution on the environment and share that knowledge with others. Advocate for better waste management practices and support organizations working to reduce plastic pollution. Spread awareness about the importance of reducing, reusing, and recycling plastic responsibly.
By following these steps and making conscious choices, we can all contribute to plastic waste reduction and help protect our environment for future generations.

Frequently asked questions
Recycled plastic goes through various channels, from household disposal to recycling centres and landfills. The nearest local recycling centre might accept certain types of plastic, while another centre may accept different types. Sorting plastic waste helps reduce contamination when sending plastics for recycling.
The first step is the collection of plastic, which is key for the recycling system to operate well. The second stage is sorting plastic from other materials, done at a Material Recovery Facility (MRF). The plastic then goes to a reprocessor to be washed, shredded, and sorted further. It is then melted and extruded into new recycled plastic pellets, which are sold to manufacturers for reuse in products and packaging.
Unfortunately, there is no guarantee that your plastic is being recycled. A Greenpeace report found that most plastic ends up in landfills, and plastic production is increasing. Only 9% of the world's plastic has been recycled.
Rinse your plastic waste before disposal, as contamination could affect the quality of the recycled plastic produced. Research which plastics are accepted by your local recycling centre, and separate your plastic waste accordingly.
The United Nations Environment Assembly is working towards a global treaty to end plastic pollution, with an intergovernmental negotiating committee formed in March 2022. Solutions include drastic cuts in the production of plastic, especially single-use plastics, and the development of better, more recyclable products.
