Plastic pollution is the accumulation of synthetic plastic products in the environment that adversely affects wildlife, habitats, and human health. Driven by an overwhelming "take-make-waste" model, up to 23 million tonnes of plastic waste leak into aquatic ecosystems annually, with some debris taking centuries to decompose.

Key Environmental & Health Threats

Wildlife Impact: An estimated 1,500+ species globally are known to ingest plastics or become entangled in debris, leading to suffocation, starvation, and toxic poisoning.

Climate Crisis: The plastic lifecycle is heavily reliant on fossil fuels. It is responsible for approximately 3.4% of global greenhouse gas emissions and poses a major threat to achieving net-zero goals.

Human Exposure: Microplastics and toxic chemical additives continuously leach into ecosystems and are now routinely found in human organs, blood, and placentas.

Where the Waste Comes From

Packaging: Over 40% of plastic debris in rivers and oceans stems from bags, bottles, and takeout containers.

Rivers as Conveyors: A small fraction of the world’s rivers acts as "conveyor belts," transporting the vast majority of terrestrial plastic waste straight into the oceans.

Poor Recycling Rates: Despite exponential growth in plastic production, less than 10% of all plastics ever manufactured have been recycled.

Leading Solutions & Initiatives

Tackling the crisis requires intervention at every stage of the plastic lifecycle, from production to disposal:

River Interception: Organizations utilize automated technology—like trash interceptor boats—to catch plastic waste in high-pollution rivers before it reaches the ocean.

Global Legislation: Initiatives led by the United Nations Environment Programme focus on systemic change, pushing for international treaties to cap plastic production and improve waste management infrastructure.

Policy & Alternatives: Regional efforts are increasingly banning single-use plastics and accelerating research into viable, truly biodegradable materials.

Plastic pollution is the accumulation of plastic objects and particles (e.g. plastic bottles, bags and microbeads) in the Earth's environment that adversely affects humans, wildlife and their habitat. Plastics that act as pollutants are categorized by size into micro-, meso-, or macro debris. Plastics are inexpensive and durable, making them very adaptable for different uses; as a result, manufacturers choose to use plastic over other materials. However, the chemical structure of most plastics renders them resistant to many natural processes of degradation and as a result they are slow to degrade. Together, these two factors allow large volumes of plastic to enter the environment as mismanaged waste which persists in the ecosystem and travels throughout food webs.

Sources of plastic pollution is related to uses. Uses of plastics as of 2024 are plastic packaging (219 Mt), construction (132 Mt), [[textile (119 Mt), domestic/leisure (96 Mt), other (182 Mt). Several studies have attempted to quantify plastic leakage into the environment at both national and global levels which have highlight the difficulty of determining the sources and amounts of all plastic leakage. One global study has estimated that between 60 and 99 million tonnes of mismanaged plastic waste were produced in 2015.

In the United States plastic packaging has been estimated to make up 5% of MSW. This packaging includes plastic bottles, pots, tubs and trays, plastic films shopping bags, rubbish bags, bubble wrap, and plastic or stretch wrap and plastic foams e.g. expanded polystyrene (EPS). Plastic waste is generated in sectors including agriculture (e.g. irrigation pipes, greenhouse covers, fencing, pellets, plastic mulch; construction (e.g. pipes, paints, flooring and roofing, insulants and sealants); transport (e.g. abraded tyres, road surfaces and road markings); electronic and electric equipment (e-waste); and pharmaceuticals and healthcare.

The trade in plastic waste has been identified as "a main culprit" of marine litter. Countries importing the waste plastics often lack the capacity to process all the material. As a result, the United Nations has imposed a ban on waste plastic trade unless it meets certain criteria.
Plastics are removed from the environment by the following pathways in order of scale:

landfilling (271 Mton/y)

incinderation (168 Mton/y)

recycling (121 Mton/y)

Incineration
Polymer degradation, especially of commodity plastics is slow, hence the persistence of plastic debris. The Ocean Conservancy has predicted the decomposition rates of several plastic products. It is estimated that a foam plastic cup will take 50 years, a plastic beverage holder will take 400 years, a disposable nappy will take 450 years, and fishing line will take 600 years to degrade.
