Plastic waste generation and recycling rates
Plastic waste is a significant environmental concern in the United States, with plastics use in the country more than tripling since the 1980s. As one of the world's largest consumers of plastics, the US is a major contributor to the growing global plastic waste problem. Plastic waste has severe negative environmental and health impacts, particularly on marine life, with large amounts of plastic ending up in the oceans each year, contributing to the deaths of thousands of sea creatures.
In 2018, the total generation of municipal solid waste (MSW) in the US was 292.4 million tons, or 4.9 pounds per person per day. Plastics accounted for 18% of this waste, with plastic containers and packaging being the main sources of plastic waste. The generation of plastics specifically was 35.7 million tons, or 12.2% of MSW generation. While the recycling of certain plastic containers is more significant, with PET bottles and jars at a 29.1% recycling rate and HDPE natural bottles at 29.3% in 2018, the overall recycling rate for plastics is relatively small. In 2018, only 3 million tons of plastics were recycled, resulting in an 8.7% recycling rate.
The recycling rate for MSW as a whole has been increasing over time, growing from 6% in 1960 to 35% in 2017, before decreasing to 32.1% in 2018. This decrease is partly due to the inclusion of additional wasted food management pathways by the EPA. The amount of MSW sent to landfills has decreased from 94% in 1960 to 50% in 2018, while the amount of MSW combusted with energy recovery increased from 0% in 1960 to 12% in 2018.
The US produced more plastic waste than any other nation in 2016, generating 42 million tons of plastic waste and 130 kg of plastic waste per capita. In 2019, the US plastic waste generation was estimated at 73 million metric tons, corresponding to more than 220 kg per inhabitant, which was roughly five times the global average. With plastic demand showing little sign of slowing down, the US plastic waste generation is projected to surpass 140 million metric tons by 2060.
The high usage of plastics is due to their design potential, diversity, flexibility, low cost, and durability. However, at the end of their life, plastics often end up in landfills, becoming a major source of marine litter. The flow of plastic into the ocean is projected to nearly triple by 2040, and without significant action, plastic waste will severely impact marine life and the environment.

Plastic in the ocean and its impact on marine life
Plastic in the ocean is a global crisis. Billions of pounds of plastic can be found on the ocean's surface, making up about 40% of the world's ocean surfaces. The plastic in the ocean comes from thousands of sources worldwide, with the primary driver being human activities. The majority of plastic pollution in the ocean is caused by littering, with single-use plastics like plastic bags, bottles, and packaging materials being used briefly and then discarded improperly, eventually making their way into waterways and the ocean. About 20% of ocean plastic pollution comes from industrial fishing, and a significant amount also comes from abandoned fishing gear.
The ocean is particularly vulnerable to plastic waste. Waves and storms can carry plastics to even the furthest reaches of the ocean, where they accumulate into large gyres or become embedded in shorelines and coastal ecosystems. Once plastic enters the ocean, it is extremely difficult to retrieve, and it persists for long periods. Over time, plastic breaks down into smaller and smaller pieces, eventually forming microplastics. These microplastics are much more difficult to clean up and can impact more species due to their increased bioavailability.
The presence of plastic in the ocean has devastating impacts on marine life and ecosystems. Marine animals often mistake plastic debris for food, leading to internal injuries, intestinal blockages, and starvation. It is estimated that plastic waste kills up to a million seabirds a year, and thousands of seabirds ingest plastic, with that number predicted to increase to 99% by 2050. Sea turtles, in particular, are affected, as they confuse plastic bags with jellyfish, their staple diet. Turtles that ingest plastic have an increased risk of death, and plastic pollution on beaches also affects their reproduction rates by altering the temperature of the sand during incubation.
Other marine mammals, such as whales, dolphins, and seals, are also vulnerable to plastic ingestion and entanglement in plastic debris, which can lead to injury and death. In addition, microplastics in the food chain and the bioaccumulation of toxic chemicals found in plastics pose a significant threat to marine apex predators such as orcas and great white sharks. These chemicals build up in the fatty tissues of animals, leading to higher concentrations of toxins in larger predators.
The impact of plastic pollution on marine life is far-reaching and severe, and it is essential to address this issue through sustainable practices, improved waste management, and global cooperation.

Single-use plastics and their environmental impact
Plastic is now found in almost every American household, with the U.S. being one of the world's largest consumers of plastics. In 2019, U.S. plastic waste generation was estimated at 73 million metric tons, corresponding to more than 220 kilograms per inhabitant. This was roughly five times more than the global average per capita plastic waste generation.
Single-use plastics are goods that are made primarily from fossil fuel-based chemicals and are meant to be disposed of right after use, often in mere minutes. They are most commonly used for packaging and serviceware, such as bags, bottles, wrappers, and straws.
The production, use, and disposal of single-use plastics have significant negative environmental, health, and climate impacts. Firstly, the production of plastic creates greenhouse gas emissions that contribute to climate change. Secondly, plastic waste pollutes the land, oceans, and air, and affects human health. Plastic waste in oceans, in particular, has devastating consequences for aquatic animals, with more than 900 ocean species impacted by plastic ingestion or entanglement. Plastic leakage into the ocean is projected to nearly triple by 2040, and if current practices continue, there could be more plastic than fish in the ocean by weight by 2050.
The U.S. recycling system has been a major cause of frustration for Americans, with only 9% of all the plastic waste ever generated having been recycled. 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. While some specific types of plastic containers are recycled more often, the overall recycling rate for plastic waste is relatively small.
To address the environmental impact of single-use plastics, consumers can change their habits and push for policy changes at the local and international levels. Design and reuse strategies, along with policy instruments such as recycled content standards and virgin resin taxes, are needed to increase the service life of plastic products and reduce plastic waste.
