While recycling is generally considered beneficial for the environment, the process of recycling itself can cause pollution. For example, the recycling of plastics can create microplastics, which have been found in human blood, human placentas, and in virtually all corners of the planet. A study of a UK recycling facility found that between 6 and 13% of the plastic processed could be released as microplastics. Another study estimated that recycling plants in the US could be creating up to 400,000 tons of microplastics per year. Additionally, contamination by non-recyclable materials can prevent large batches of recyclables from being recycled and can lead to pollution. For instance, in 2016, the US exported 16 million tons of mixed recyclables to China, of which 30% were contaminated and ended up polluting China's countryside and oceans.

Recycling reduces the need for raw materials, cutting energy use and emissions
Recycling is the process of collecting and processing materials that would otherwise be thrown away and turning them into new products. Recycling provides many benefits to the environment and helps create a healthier planet for future generations.
Recycling reduces the need for raw materials by reusing what would otherwise be discarded. This reduces the need to extract natural resources such as timber, water, and minerals, which helps conserve energy. For example, recycling just 10 plastic bottles saves enough energy to power a laptop for over 25 hours, and recycling one ton of paper could power the average American home for six months. Recycling also reduces the amount of waste that will need to be sent to landfills and incinerators, which in turn reduces the harmful effects of pollution and emissions. According to the US Environmental Protection Agency, recycling and composting municipal solid waste saved over 193 million metric tons of carbon dioxide equivalent in 2018.
The recycling process involves three steps that are repeated to create a continuous loop. After collection, recyclables are sent to a recovery facility to be sorted, cleaned, and processed into materials that can be used in manufacturing. Recycled materials are then bought and sold, and after processing, they are made into new products at a recycling plant or similar facility. More and more products today are being manufactured with recycled content, such as recovered glass in asphalt for paving roads or recovered plastic in carpeting and park benches.
However, it is important to note that the current recycling system faces several challenges. For example, contamination and improper sorting can cause large batches of materials to become garbage instead of being recycled. Additionally, some materials, such as plastic straws, bags, and certain types of plastic bottles, are not widely recyclable and often end up in landfills or the ocean, contributing to plastic pollution. Furthermore, while incineration is sometimes used to produce energy, waste-to-energy plants have been linked to toxic emissions.

Recycling reduces landfill waste, lowering harmful methane emissions
Recycling is the process of collecting and processing materials that would otherwise be thrown away as trash and turning them into new products. It is an essential activity that benefits the community, the economy, and the environment. Recycling diverts waste from landfills, which in turn reduces harmful emissions.
Landfills emit carbon dioxide, methane, volatile organic compounds, and other hazardous pollutants into the air. Methane is a potent greenhouse gas that is at least 28 times more effective than carbon dioxide at trapping heat in the atmosphere over a 100-year period. Municipal solid waste landfills are the third-largest source of human-related methane emissions in the United States, accounting for approximately 14.4% of these emissions in 2022.
When organic waste decomposes in landfills, it produces methane as a byproduct. By reducing the amount of organic waste sent to landfills, recycling helps to lower methane emissions. This can be achieved through upstream efforts to reduce and redistribute surplus waste, as well as downstream initiatives to recycle organic waste into compost, biogas, or other beneficial products.
Additionally, recycling conserves energy and natural resources. It reduces the need to extract resources such as timber, water, and minerals for new products. For example, recycling just 10 plastic bottles saves enough energy to power a laptop for more than 25 hours.
While recycling is crucial, it should be noted that the recycling process itself may face challenges due to contamination and limited processing capacities. Nevertheless, recycling remains a vital part of creating a healthier planet for current and future generations.

Recycling plastic waste can produce microplastics, polluting water and air
Plastic waste is a significant contributor to environmental pollution, and while recycling is often touted as the solution, it may inadvertently be exacerbating the problem. The process of recycling plastic waste can generate microplastics, which can pollute water and air, thus contaminating various ecosystems and posing risks to human health.
The act of breaking down plastics during recycling can result in the creation of microplastics, which are tiny particles smaller than five millimeters. These microplastics can be released into the environment, ending up in water bodies or becoming airborne. A recent peer-reviewed study focused on a recycling facility in the United Kingdom underscores this issue. The study found that between 6 and 13 percent of the plastic processed could be released as microplastics into the water or air.
The mechanical friction and abrasion involved in the recycling process are believed to be the primary causes of microplastic generation. Researchers have found substantial amounts of microplastics in both the wastewater and air at recycling facilities. The problem is further compounded by the insufficient capacity of processing facilities, resulting in recyclables ending up in landfills or the ocean instead of being properly recycled.
While filtration can help mitigate the issue by removing larger microplastic particles, it is not a comprehensive solution. The study found that even with filtration, the facility's wastewater still contained up to 75 billion plastic particles per meter cubed, with the majority being smaller than 10 micrometers. This highlights the need for better regulation and the development of more effective solutions to address microplastic pollution from recycling processes.
Despite the challenges, recycling remains crucial in reducing plastic waste and conserving natural resources. However, it is essential to recognize that recycling alone cannot solve the plastic pollution crisis. To effectively address the problem, a multi-pronged approach is necessary, including reducing plastic consumption, improving recycling infrastructure, enforcing regulations, and exploring alternative materials such as biodegradable plastics. By combining these strategies, we can work towards creating a healthier planet for current and future generations.

Recycling saves energy, reducing the burning of fossil fuels and emissions
Recycling saves energy, and this has the knock-on effect of reducing the burning of fossil fuels and emissions. Recycling reduces the need to extract raw materials, which is an energy-intensive process, and also means that less energy is needed to create new products.
The US Environmental Protection Agency (EPA) estimates that 42% of total US greenhouse gas (GHG) emissions are associated with the manufacturing, use, and disposal of goods and food. Recycling diverts waste from landfills and incinerators, which are major sources of pollution and emissions.
Recycling one ton of paper, for example, could save enough energy to power the average American home for six months. Recycling aluminum cans uses 95% less energy than making new ones from raw materials. In 2018, 3.7 million tons of aluminum were produced by recycling in the US, saving enough energy to power 8 million homes.
The largest energy savings from recycling are generally achieved with metals, as they are often easy to recycle and don't need to be produced by energy-intensive mining and processing. For example, recycling beryllium saves 80% of the energy used in its production, lead saves 75%, iron and steel 72%, and even the hardest metal to recycle, cadmium, saves 50%.
The EPA's National Recycling Strategy aims to advance the national municipal solid waste recycling system, with a focus on preventing plastic pollution. In 2018, 69 million tons of municipal solid waste were recycled, a 32.1% recycling rate.
