Recycling Basics and Benefits | US EPA

Recycling is the process of collecting and processing materials that would otherwise be thrown away as trash and turning them into new products. Recycling can benefit your community, the economy, and the environment. Products should only be recycled if they cannot be reduced or reused. EPA promotes the waste management hierarchy, which ranks various waste management strategies from most to least environmentally preferred. The hierarchy prioritizes source reduction and the reuse of waste materials over recycling.

Benefits of Recycling

Environment

Recycling provides many benefits to our environment. By recycling our materials, we create a healthier planet for ourselves and future generations. 

Conserve natural resources: Recycling reduces the need to extract resources such as timber, water, and minerals for new products.

Reduce greenhouse gas emissions: According to the most recent EPA data, the recycling and composting of municipal solid waste (MSW or trash) saved over 193 million metric tons of carbon dioxide equivalent in . 

Energy savings: Recycling conserves energy. For example, recycling just 10 plastic bottles saves enough energy to power a laptop for more than 25 hours. To estimate how much energy you can save by recycling certain products, EPA developed the individual Waste Reduction Model (iWARM). 

Waste and pollution reduction: Recycling diverts waste away from landfills and incinerators, which reduces the harmful effects of pollution and emissions. 

Economy

EPA released significant findings on the economic benefits of the recycling industry with an update to the national Recycling Economic Information (REI) Study in . This study analyzes the numbers of jobs, wages and tax revenues attributed to recycling. The study found that in a single year, recycling and reuse activities in the United States accounted for:

• 681,000 jobs,
• $37.8 billion in wages, and
• $5.5 billion in tax revenues.

This equates to 1.17 jobs per 1,000 tons of materials recycled and $65.23 in wages and $9.42 in tax revenue for every ton of materials recycled. For more information, check out the full report.

Community

Local Impacts: Across the country, areas where waste management facilities are concentrated can result in negative impacts on human health, property values, aesthetic and recreation values, and land productivity. Recycling provides these areas with a healthier and more sustainable alternative.

International: Waste generated in the United States also affects communities in other countries. Recycled materials are exported to some countries that are not able to manage those materials in an environmentally sound manner.  

U.S. Recycling System Overview

The recycling process is made up of three steps that are repeated over and over again. This creates a continuous loop which is represented by the familiar chasing arrows recycling symbol. The three steps of the recycling process are described below.  

Step 1: Collection and Processing

Businesses and consumers generate recyclables that are then collected by either a private hauler or government entity. There are several methods for collecting recyclables, including curbside collection, drop-off centers, and deposit or refund programs. Visit How do I recycle... Common Recyclables for information on specific materials. 

After collection, recyclables are sent to a recovery facility to be sorted, cleaned, and processed into materials that can be used in manufacturing. Recyclables are bought and sold just like raw materials would be, and prices go up and down depending on supply and demand in the United States and around the world.

Step 2: Manufacturing

After processing, recyclables are made into new products at a recycling plant or similar facility. More and more of today's products are being manufactured with recycled content.

Recycled materials are also used in new ways such as recovered glass in asphalt to pave roads or recovered plastic in carpeting and park benches.

Step 3: Purchasing New Products Made from Recycled Materials

You help close the recycling loop by buying new products made from recycled materials. There are thousands of products that contain recycled content. When you go shopping, look for the following:

• Products that can be easily recycled
• Products that contain recycled content

Below are some of the terms used:

• Recycled-content product - The product was manufactured with recycled materials either collected from a recycling program or from waste recovered during the normal manufacturing process. The label will sometimes include how much of the content came from recycled materials.
• Post-consumer content - Very similar to recycled content, but the material comes only from recyclables collected from consumers or businesses through a recycling program.
• Recyclable product - Products that can be collected, processed, and manufactured into new products after they have been used. These products do not necessarily contain recycled materials. Remember not all kinds of recyclables may be collected in your community, so be sure to check with your local recycling program before you buy.

Some common products you can find that are made with recycled content include the following:

• Aluminum cans
• Car bumpers
• Carpeting
• Cereal boxes
• Comic books
• Egg cartons
• Glass containers
• Laundry detergent bottles
• Motor oil
• Nails
• Newspapers
• Paper towels
• Steel products
• Trash bags

Challenges to Recycling System

While the benefits of recycling are clear, the current system still faces many challenges. 

• Many people are confused about what items can be recycled, where they can be recycled and how. This often leads to recyclables going in the trash or trash going in the recycling bin.
• America’s recycling infrastructure has not kept pace with today’s waste stream. Communication between the manufacturers of new materials and products and the recycling industry needs to be improved to prepare for and optimally manage the recycling of new materials.
• Domestic markets for recycled materials need to be strengthened in the United States. Historically, some of the recycled materials generated in the U.S. have been exported internationally. However, changing international policies have limited the export of materials. Improving communication among the different sectors of the recycling system is needed to strengthen the development of existing materials markets and to develop new innovative markets.
• We need to better integrate recycled materials and end-of-life management into product and packaging designs. 
• More consistent measurement methodologies are necessary to improve recycling system performance. These more standardized metrics can then be used to create effective goals and track progress.

What is Being Done

The Infrastructure Investment and Jobs Act: Transforming U.S. Recycling and Waste Management: The Bipartisan Infrastructure Law is a historic investment in the health and resilience of American communities. With unprecedented funding to support state and local waste management infrastructure and recycling programs, EPA will improve health and safety and help establish and increase recycling programs nationwide. 

National Recycling Strategy: EPA developed the "National Recycling Strategy" with a focus on advancing the national municipal solid waste recycling system. It identifies strategic objectives and actions to create a stronger, more resilient, and cost-effective recycling system.  

National Strategy to Prevent Plastic Pollution: This strategy builds upon EPA’s "National Recycling Strategy" and focuses on actions to eliminate the release of plastic pollution into the environment.

America Recycles Day: Every year on November 15, EPA reminds everyone of the importance and impact of recycling through education and outreach.

Basel Convention: The United States is a signatory to the Basel Convention but has not yet become a Party to the Convention. The Basel Convention establishes standards for the transboundary movement of various types of waste.

Recycling sorting equipment can bring significant economic and environmental benefits to humanity. As one of the world’s leading system integrators, PEAKS ECO understands the importance of separating municipal solid waste (MSW) into valuable recyclables and high-quality refuse-derived fuel (RDF). With increasing regulatory pressure on landfilling untreated MSW and the active search for alternative energy sources, energy-from-waste solutions are gaining momentum.

1. Reduce Land Occupation

One of the primary advantages of sorting garbage is the reduction of land occupation. Many materials in domestic waste are not easily degradable, leading to long-term land erosion and loss of valuable land resources. By sorting and recycling these materials, we can significantly reduce the volume of waste that needs to be landfilled, preserving land for more productive uses.

For example, statistics show that efficient garbage sorting can reduce landfill requirements by up to 60%. In cities with advanced waste sorting systems, such as Tokyo, landfilling rates have dropped dramatically, showcasing the potential of sorting technologies to alleviate land stress.

2. Minimize Environmental Pollution

Recycling reduces environmental pollution by preventing harmful substances from contaminating soil, water, and air. Properly sorting hazardous waste, such as batteries, electronics, and chemicals, ensures they are treated appropriately, reducing the risk of heavy metals, organic pollutants, and pathogenic bacteria entering the environment.

PEAKS ECO’s integrated systems play a crucial role in minimizing pollution by effectively separating and processing hazardous and recyclable materials. These systems also improve the calorific value of non-recyclable waste, making it suitable for RDF production, which can replace fossil fuels in energy generation.

3. Turn Waste into Treasure

Sorting garbage enables the transformation of waste into valuable resources. By separating recyclable materials such as metals, glass, paper, and plastics, we can reduce resource extraction and promote a circular economy.

• Metals: Aluminum and iron products can be melted and reused, saving money and reducing the environmental impact of mining and smelting new metals.

• Glass: Recycling glass saves up to 30% of the energy required for producing new glass and minimizes damage to ecosystems caused by mining.

• Paper: Recycling one ton of paper saves approximately 17 trees, 26,500 liters of water, and reduces greenhouse gas emissions by up to 74% compared to producing new paper.

• Plastics: Recycled plastics can be converted into new products or refined into crude oil, which can then be used to produce diesel and gasoline.

4. Improve Soil Fertility and Reduce Chemical Fertilizers

Separately classifying kitchen waste, which is rich in organic matter, provides high-quality raw materials for composting. This process produces organic fertilizers that enhance soil fertility and reduce reliance on chemical fertilizers. Additionally, diverting kitchen waste with high water content from incineration increases the calorific value of other wastes, improving the efficiency of energy-from-waste plants.

5. Extend the Life of Landfills

Effective waste sorting significantly reduces the amount of waste entering sanitary landfills, extending their operational lifespan. By diverting biodegradable and recyclable materials from landfills, we can optimize their usage and delay the need for costly expansions or new landfill sites.

6. Enhance Recycling Efficiency

Sorting garbage at the source improves the purity of recyclable materials, making recycling processes more efficient and cost-effective. This reduces the need for complex pre-sorting at recycling facilities and lowers transportation and processing costs. For instance, advanced sorting equipment, such as PEAKS ECO’s automated recycling systems, utilizes technologies like optical sorting, air separation, and magnetic separation to achieve high-precision sorting.

7. Promote Energy-from-Waste Solutions

Energy-from-waste (EfW) is a sustainable waste management approach that converts non-recyclable waste into energy. PEAKS ECO’s expertise in producing high-quality RDF supports the global transition to alternative energy sources. RDF, derived from sorted waste, serves as a clean and efficient fuel for power generation and industrial applications, reducing reliance on fossil fuels.

According to industry data, one ton of RDF can generate approximately 500 kWh of electricity, highlighting its potential as a renewable energy source. Countries like Germany and Sweden have adopted EfW systems extensively, reducing greenhouse gas emissions and advancing energy sustainability.

8. Boost Public Environmental Awareness

Implementing waste sorting programs raises public awareness about environmental conservation. Citizens become more conscious of their waste disposal habits, leading to a cultural shift toward sustainability. Educational campaigns and incentives, such as recycling rewards and reduced waste disposal fees, further encourage participation in waste sorting initiatives.

Industry Data and Success Stories
