Plastic is everywhere, from the tallest mountains to the deepest ocean trenches, and it is even found in drinking water and human blood. The global annual production of plastic is more than 350 million tons, with Asia being the largest producer in 2023. Plastic commercialization began during World War II and has since grown all over the world. It is a versatile material with numerous applications, including packaging, construction, home appliances, medical instruments, and food packaging. However, plastic waste has become a significant environmental concern, with an estimated 20 million metric tons leaking into the environment in 2020. While some efforts have been made to boost the collection and circularity of plastic products, recycling only represents less than 10% of plastic waste management worldwide. To address plastic pollution, improving waste management strategies and reducing plastic production and demand are crucial.

Plastic in durable goods
Plastic is a rapidly growing segment of municipal solid waste (MSW). The containers and packaging category, which includes bags, sacks, wraps, bottles, jars, and other containers, had the most plastic tonnage at over 14.5 million tons in 2018.
While plastic is predominantly found in nondurable products, such as disposable diapers, trash bags, cups, utensils, and other household items, it is also used in the production of durable goods. Durable goods are products that remain in use for longer than three years, such as appliances, furniture, carpets, consumer electronics, vehicles, drinking and wastewater pipes, medical implants, and buildings.
The use of plastic in durable goods presents unique challenges when it comes to sustainability and circularity. Unlike single-use plastics, durable plastics are designed to last for years or even decades, which means they must be strong, safe, and resistant to typical wear and tear. As a result, they may not be as easily recyclable as their single-use counterparts, requiring specialized methods for processing at the end of their lifespan.
The end-of-life challenges associated with durable plastics have not gone unnoticed by the plastics industry, which is working towards eliminating plastic waste in the environment. While the amount of recycled plastics is relatively small, with an 8.7% recycling rate in 2018, the recycling rates for specific types of plastic containers are more significant. For example, the recycling rate for PET bottles and jars was 29.1% in 2018, while HDPE natural bottles had a rate of 29.3%.
To achieve true circularity and sustainability, durable plastic goods must be designed with reuse, repair, and recycling in mind, ensuring that they do not become waste and instead contribute to saving energy, labor, and raw materials.

Plastic packaging
The rise in global demand for plastic packaging is driven by its versatility, durability, low cost, lightweight properties, and customizability. Different types of plastics are used for specific applications. For instance, high-density polyethylene (HDPE) is used for containers of cleaning supplies due to its strength and chemical resistance, while polyethylene terephthalate (PET) is used for beverage bottles due to its clarity, strength, and gas barrier properties.
The packaged food and beverage sector is a major contributor to the demand for plastic packaging. The growth in urban populations, changing lifestyles, increasing economic activities in emerging countries, and the expansion of e-retail are expected to drive the demand for packaged food and, consequently, plastic packaging. The rising world population is also anticipated to fuel the consumption of plastic packaging products for the packaged food segment.
Despite the benefits of plastic packaging, there are significant environmental concerns associated with its use. Plastic pollution has become an urgent environmental crisis, with an estimated 8 million tons of plastic ending up in the oceans annually. The mismanagement of plastic waste, including the lack of recycling, incineration, or proper landfilling, contributes to this issue. While all plastic types are technically recyclable, only a small amount is recycled globally due to various barriers. As a result, there is increasing consumer skepticism of plastic products, with packaging facing considerable scrutiny.
To address the environmental impact of plastic packaging, governments have introduced bans and taxes on plastic products. Companies are also responding to consumer preferences for sustainable practices and recycled or biodegradable materials. The global sustainable plastic packaging market is projected to grow to almost $143.7 billion by 2030, with bioplastics expected to play a significant role. While plastic packaging is unlikely to be replaced in the near future, traditional packaging materials could potentially displace plastics in the long term if recycling rates remain low.

Plastic recycling rates
According to the Environmental Protection Agency (EPA), the plastic recycling rate in the United States was 8.7% in 2018. An NGO report claimed that in 2021, this had dropped to around 5%, which could be partly explained by the global pandemic. The UK recycles just 17% of its annual plastic waste.
The recycling of some specific types of plastic containers is more significant. For example, the recycling rate of PET bottles and jars was 29.1% in 2018, and the rate for HDPE natural bottles was 29.3% in 2018.
Overall, it is estimated that only 9% of all plastic waste ever produced has been recycled. About 12% has been incinerated, while the rest (79%) has accumulated in landfills, dumps, or the natural environment.
The management of plastic waste is critical to reducing plastic pollution. While it is important to reduce plastic production, improving waste management strategies will do more to tackle the issue. Incineration is high in Europe, while three-quarters of plastics in the United States go to landfills. Many countries in Africa have adopted a total ban on the production and use of plastic bags.

Plastic waste management
One of the key challenges in plastic waste management is the lack of access to controlled disposal services and regular waste collection in many parts of the world. According to the UNEP Global Waste Management Outlook, 3 billion people do not have access to controlled disposal services for solid waste, and 2 billion people lack regular waste collection. As a result, a large portion of plastic waste ends up being littered or inadequately disposed of.
To address this issue, governments and organizations have implemented various strategies. These include public awareness campaigns, incentives for recycling, levies or bans on certain plastic products, and improvements in waste management infrastructure. The Basel Convention, for example, is an international agreement that provides guidance on the environmentally sound management of plastic waste, including transboundary movements of hazardous wastes.
Additionally, reducing the consumption of single-use plastic products and promoting recycling can significantly impact plastic waste management. Many countries have adopted policies to reduce the use of disposable plastic, with Africa leading the way in banning the production and use of plastic bags. Improving the management of plastic waste, especially in poorer countries, is critical to tackling the global plastic pollution crisis.

Plastic microbeads in cosmetics
Plastic pollution is a growing environmental concern. While plastics have added value to our lives as a cheap, versatile, and sterile material used in construction, home appliances, medical instruments, and food packaging, they contribute significantly to waste. The world produces over 450 million tons of plastic annually, with half of all plastic produced designed for single-use before being discarded. This has resulted in approximately 8 million tons of plastic entering the oceans each year, polluting the environment and endangering wildlife and ecosystems.
Plastic microbeads, a type of microplastic with a specific scrubbing or exfoliating function, have been a significant contributor to this pollution. Microbeads are plastic particles smaller than 5mm, usually spherical, and made of polyethylene (PE) or polymethyl methacrylate (PMMA). They are added to cosmetic and personal care products like sunscreens, shampoos, makeup, deodorants, and toothpastes for their pleasant texture and smoothing effect.
The use of microbeads in cosmetics has been controversial due to their environmental and health impacts. When released into the environment, microbeads are highly resistant to biodegradation, persisting in ecosystems and contributing to the growing "Plastic Soup" in our oceans. Sea animals absorb or eat these microplastics, passing them along the marine food chain and potentially affecting human health.
In recent years, there has been a growing movement to ban microbeads in cosmetics, with 19 countries taking steps to prohibit their use. The cosmetic industry has also volunteered to remove microbeads from their products, shifting the conversation towards addressing microplastics in general. However, comprehensive regulations and monitoring of all cosmetic microplastics are still needed, especially for \"leave-on\" products that may have an even greater impact on the environment and human health.
