Plastic is everywhere, and it's killing 100,000 animals every year. From the oceans to our clothing, plastic waste is having a devastating impact on the environment. It is estimated that about 3% of all plastic produced annually ends up in the sea, killing marine life and causing flooding. With only 9% of plastic waste recycled and 12% incinerated, the remaining 79% ends up in landfills or the environment, where it will stay indefinitely as plastic does not naturally decompose. Some estimates suggest plastic can take hundreds of years to break down, and as it degrades, it can leak toxins into the soil. While innovations like plastic-eating bacteria and biodegradable plastics offer some hope, reducing single-use plastics and improving recycling practices are crucial to tackling this global issue.

What You'll Learn
Plastic does not decompose, but it can be incinerated
Plastic is a material that does not decompose, but it can be incinerated. Incineration is the process of burning plastic waste to generate energy. While incineration may seem like a solution to the plastic waste problem, it comes with several drawbacks and negative consequences. Firstly, burning plastic releases harmful pollutants such as microplastics, bisphenols, and phthalates, which can have detrimental effects on human health, including neurodevelopment, endocrine, and reproductive functions. It also contributes to air pollution and climate change by releasing greenhouse gas emissions.
Additionally, incineration is an expensive waste management method, with high costs associated with building and operating incineration facilities. The constant feeding of waste required by incinerators can also lead to a never-ending cycle of burning and producing plastics, benefiting the plastic industry's profits rather than encouraging plastic reduction and reuse. Furthermore, incinerators are often built in deprived and diverse neighbourhoods, raising environmental injustice concerns.
To address the plastic waste problem effectively, it is crucial to reduce plastic consumption, increase recycling efforts, and promote reusable alternatives. While incineration can make plastics disappear, it does not provide a sustainable or ethical solution due to its negative impact on the environment and public health.
It's worth noting that some plastics are designed to degrade rapidly in the environment through oxidation and hydrolysis, which can be accelerated by heat and sunlight. However, the majority of plastics persist in the environment for many decades, leading to issues such as clogged sewers, river pollution, and the death of marine life. Overall, while incineration can dispose of plastics, it is not a viable solution due to its environmental and health implications, and society should focus on reducing plastic usage and improving recycling practices.

Degradation by oxidation and hydrolysis, accelerated by heat and sunlight
Plastic waste is generated at a rate of almost 400 Mt per year, and the amount of plastic accumulating in the environment is increasing rapidly. The degradation of plastics in the environment is a slow process, taking many decades. The degradation of plastics occurs through oxidation and hydrolysis, which are accelerated by heat and sunlight.
Oxidation is a process by which compounds interact with molecular oxygen (O2) in the air. This interaction can be accelerated or decelerated depending on the surrounding environment, including factors such as oxygen concentration, temperature, moisture, and pH. Similarly, plastics exposed to air will undergo oxidation, usually through a radical mechanism. The rate of oxidation can be influenced by factors such as temperature and light, with higher temperatures and intense UV light increasing the concentration of reactive oxygen species (ROS) and accelerating the degradation process.
In landfills or composters, temperatures can reach 80-100°C, which, when combined with sufficient oxygen and moisture, can accelerate the thermal-oxidative degradation of plastics. Additionally, light plays a significant role in oxidative degradation. UV-driven photo-oxidation by solar UV radiation makes plastic prone to fragmentation, leading to the generation of secondary micro- or nanoparticles, which are considered pollutants. However, the rate of UV-driven degradation can vary depending on the location and environment, with factors such as biofouling and the implementation of protocols for protecting stratospheric ozone also playing a role.
Hydrolysis is another mechanism by which plastics degrade. This process requires water (H2O) and can be accelerated by heat and light, similar to oxidation. For example, polylactic acid (PLA) undergoes ester hydrolysis at temperatures above 60°C, although it degrades very slowly at lower temperatures.
While heat and sunlight can accelerate the degradation of plastics through oxidation and hydrolysis, it is important to note that this degradation can result in the release of harmful chemical byproducts and the leaching of small molecules. Additionally, the high temperatures required for oxidative degradation can be challenging to achieve in an economically and environmentally feasible manner.

Plastic-eating bacteria: a potential solution?
Plastic is a material that takes a long time to degrade, with most plastics taking several decades to break down through oxidation and hydrolysis. This process is accelerated by heat and sunlight, and certain chemicals can be added to plastic to accelerate degradation. However, the persistence of plastic waste in the environment, especially in oceans, continues to cause serious issues. Marine animals often ingest plastic or get entangled in it, leading to their death. Microplastics have also entered our diets and the air we breathe, with an average person consuming around 5 grams of plastic weekly.
Plastic-eating bacteria have emerged as a potential solution to combat the plastic crisis. In 2016, Japanese scientists discovered a species of bacteria, Ideonella sakaiensis, which could digest polyethylene terephthalate (PET), a common plastic in clothing and packaging. This discovery has sparked interest in bioprospecting, searching for microbes that can break down plastics. For example, researchers are studying mangroves in Vietnam and Thailand, which have a waterproof coating similar to PET, hoping to find bacteria that can degrade both the mangrove roots and plastic.
The potential of plastic-eating bacteria is significant, as they could help address the 14 million tons of plastic that pollute our oceans annually. However, there are challenges to using these bacteria at a large scale. For instance, some plastic-eating bacteria produce toxins as by-products, which could be more harmful to the environment than plastic waste itself. Additionally, it is currently cheaper and faster to produce new plastic than to use bacteria to break down plastic waste. Nevertheless, major companies are collaborating with researchers to explore the potential of plastic-eating enzymes in recycling processes.
While plastic-eating bacteria may not be an immediate solution to the plastic waste crisis, they offer hope for the future. With further research and development, these bacteria could play a crucial role in tackling plastic pollution and mitigating its environmental and health impacts.

Plastic waste in the ocean: a growing problem
Plastic waste in the ocean is a pressing issue that poses a significant threat to the environment, human health, and economies. It is a global problem that requires immediate attention and collective efforts to address.
Every year, an estimated 400 million metric tons of plastic are produced globally, with a substantial amount ending up in our oceans. The presence of plastic in the ocean can be attributed to a combination of increasing consumption and inadequate waste management practices in many countries. While people in high-income countries consume more plastic, effective waste management systems help keep plastic waste out of the natural environment. In contrast, middle-income countries, particularly in Asia, contribute the most plastic emissions due to a growing consumption rate and inadequate waste management infrastructure.
The impact of plastic waste in the ocean is far-reaching and devastating. Marine animals unknowingly ingest plastic or become entangled in it, leading to their deaths. Plastic pollution also affects marine life by potentially serving as a primary food source in certain regions, such as the Great Pacific Garbage Patch, where the mass of plastics is 180 times higher than that of marine life. Additionally, plastic waste clogs grates, storm sewers, and culverts, causing infrastructure damage and contributing to flooding.
To combat this growing problem, a multifaceted approach is necessary. Firstly, improving waste management strategies and infrastructure is crucial. This includes implementing proper waste collection, recycling, and disposal practices globally, especially in rapidly developing countries with increasing disposable plastic consumption. Secondly, reducing the use of single-use plastics and promoting reusable alternatives can significantly decrease the amount of plastic waste generated. Additionally, supporting organizations and initiatives dedicated to cleaning up our oceans and rivers, such as The Ocean Cleanup, is essential to addressing the immediate impacts of plastic pollution.
While it takes decades for plastics to degrade naturally through oxidation and hydrolysis, certain chemicals can be added to accelerate the process. Some plastics, like plastic 6-pack loop carriers, are designed to degrade rapidly when exposed to sunlight. However, the focus should be on preventing plastic waste from entering our oceans in the first place, as cleanup efforts can only address a small portion of the vast plastic pollution problem.

The environmental impact of plastic toxins
Plastic is a significant environmental concern, with plastic waste taking decades to degrade and posing a range of ecological and health risks. Once in the environment, plastic can fragment into microplastics, which are found in every ecosystem on Earth, from the Antarctic tundra to tropical coral reefs. These microplastics enter food chains through agricultural soils, terrestrial and aquatic food chains, and the water supply, leading to human exposure through ingestion, inhalation, and skin contact.
The toxic chemical additives and pollutants in plastics have severe health effects, including causing cancer, impairing sensory organs, impacting bodily systems, and disrupting hormones (endocrine disruption). They also accumulate in the environment, persisting and bioaccumulating in exposed organisms. The production and conversion of fossil fuels into new plastic products contribute to global greenhouse gas emissions, with the plastic lifecycle estimated to be responsible for 3.4% of these emissions in 2019.
The extraction of fossil fuels for plastic production also carries health and environmental risks, including pollution at extraction sites, worker exposure to chemicals, and air, water, and soil contamination. Vulnerable groups, including children, pregnant people, and marginalized communities, are particularly susceptible to the adverse effects of plastic pollution, with increased risks of prematurity, birth defects, neurodevelopmental impairment, and childhood cancer. Furthermore, plastic waste can clog infrastructure, causing flooding and infrastructure damage, and kill marine life.
To address the plastic crisis, recycling practices need to improve, and single-use plastics should be reduced. Additionally, the chemicals, waste, and petrochemicals industries must be considered in policy responses to mitigate the toxic impacts of plastics across their lifecycles. While some plastics are designed to degrade rapidly, such as through the use of ethylene-carbon monoxide (ECO) copolymer, the vast majority of plastic waste enters the environment or is incinerated, releasing toxic substances.
