What is Car and Vehicle Recycling?
As of the first quarter of 2019, there were a total of 276 million vehicles in operation on the roads of the United States. Approximately 17 million new vehicles are added to the national fleet each year, and the rest get another year older. It is a never-ending cycle.
Now, we all love our cars when they’re shiny and new, but eventually that shine wears off until one day your car is done. When your car isn’t safe to drive and no amount of repair work will get that old car back on the road, it has reached its end life.
Each year, around 12 million vehicles reach the end of the line in the US, along with another 500,000 in Canada.
Cars are essentially big hunks of metal, which may have you fearing that your precious ride will end up rotting away in a junkyard as an eyesore polluting the environment and serving as home to a bunch of field mice. This might make the mice happy, but it’s not at all good for the planet.
The causes are many and varied:
- A bad accident
- Failure of a major mechanical component or system
- Floods and other natural disasters
- Theft and stripping
- Wear and tear
- Lack of maintenance
- Reaching the point where they are not worth fixing
- And so on…
Such was the case back in the 1960s, when the world did not yet know what ecology and concern for the environment were all about. There also wasn’t much discussion going on about ways to get some financial benefit out of the eight million junk cars piled up in junkyards around the country. As the Highway Beautification Act of 1965 led to the elimination of the huge roadside junkyards that blighted America’s highways, and the first Earth Day in 1970 brought environmental awareness to the public, the structure of the contemporary automotive recycling industry came into focus.
Today, automotive recycling is big business, committed to handling end-of-life cars in an environmentally responsible manner. It does so by salvaging reusable parts, reprocessing its scrap material, and disposing unusable parts safely and efficiently.
Overview of the Automobile Recycling Industry
The auto recycling industry has become the 16th largest industry in the US, employing 140,000 people and contributing $32 billion in sales each year. More significantly, the automotive recycling industry can proudly claim that it has made the automobile the single most recycled product in the entire world, processing fully 95% of all the vehicles that have reached the ends of their lives. We recycle more of our cars than we do paper or aluminum cans or glass. Think on that the next time you see all those recycling bins lined up at the curb on trash day.
The Importance of Vehicle Recycling
End life vehicles aren’t safe. These are vehicles on which repairs can no longer effectively be made, which means having that vehicle on the road is a hazard. Selling it before it ends up breaking down and causing a problem helps reduce accident rates and makes all of us safer.
But the automotive recycling industry performs a very important service for a multitude of reasons apart from safety. Through its process of dismantling, reusing, and recycling millions of vehicles that no longer function, this industry benefits society as a whole in many different ways:
The environmental benefits
The act of recycling many millions of vehicles each year results in numerous benefits to the environment. These include:
- Extending the timeline for when finite sources of raw materials will run out.
- Eliminating the blight of old-school junkyards, full of rusting cars.
- Reducing air and water pollution.
- The disappearance of most “mountains” of waste tires, which were ugly sources of standing water, mosquitos, and disease.
- Recycling reduces the amount of new raw materials required for auto production, lowering energy demand and costs.
- Recycling over 14 million tons of steel from junk vehicles each year. The number of vehicles recycled in the US and Canada alone provides enough steel to build 13 million new vehicles.
- Reducing energy usage by 74% and lowering steel plant emissions, by using recycled metal instead of making it purely from ore.
- Saving 2500 lb. of iron ore, 1400 lb. of coal, and 120 lb. of limestone each time that one ton of steel is recycled.
- Using recycled steel for 25% of a new car’s body.
- Reducing greenhouse gases by 30 million metric tons each year by recycling automotive metals.
- Recycling fully 90% of all automotive aluminum.
- Saving 90% of the energy required to mine and process copper by using recycled copper instead.
- Preventing pollution of our groundwater by reclaiming fluids from junk cars. This adds up to 100.8 million gallons of fuel, 24 million gallons of motor oil, 45 million gallons of windshield washer fluid, and 8 million gallons of coolant each year.
- Removing toxins like mercury (from switches) and sodium azide (from airbags), before they can cause environmental damage.
- Recycling hundreds of millions of discarded old tires each year into road-building materials, roofing, playground cushioning, and other products.
- Recycling auto glass into products like porcelain, flooring tiles, countertops, and jewelry.
- Recycling auto carpeting into new car parts.
- Recycling lead-acid car batteries into new ones.
- Saving 85 million barrels of oil per year that would otherwise be used to make new car parts.
- Reducing the demand for scarce landfill space.
- Making the automotive industry aware of hazardous materials like chromium, lead, cadmium, and mercury in junk cars, leading to their elimination in new vehicles.
The economic and financial benefits
- The automotive recycling industry is the 16th largest in the US, and it contributes $32 billion in sales each year to the nation’s economy.
- More than 140,000 people are employed at 9,000 automotive recycling businesses across the US.
- Auto recycling jobs are higher-paying, contributing significant tax revenues at the local, state, and federal levels.
- Catalytic converters contain precious metals including platinum, palladium, and rhodium, which can be re-used to make new catalytic converters. Other uses for these metals are pharmaceuticals, electronics, and jewelry.
- Usable parts from junk cars can be resold to keep other cars running longer, also eliminating the need to make new parts.
- Consumers can realize some monetary value from their vehicles, even when they no longer function.
- Automotive recyclers have become an excellent resource for cost-effective and hard-to-find used vehicle replacement parts.
- Automotive recycling reduces vehicle insurance rates by purchasing “totaled” vehicles from insurance companies, letting them recover financial losses.
- The lower cost of recycled metals, compared to new, keeps down the prices of the products they are used in.
The Auto Recycling Process
There are several distinct stages to the automotive recycling process, which are performed in a set order. Each stage makes it possible for the next to be done, with the objective of ending up with the maximum materials and parts value, and the minimum impact to the environment. These stages are:
This is the first step in automotive recycling, and it focuses on removal of all the fluids that are used in the operation of a motor vehicle. These include:
- Diesel fuel
- Brake fluid
- Transmission fluid
- Air conditioning refrigerant
- Gear oil
- Windshield washer fluid
These materials, once removed from the vehicle, can be reused, reprocessed, recycled, or disposed of, in an environmentally responsible way that will not contaminate the water table or the food supply in the ground. All those fluids are then stored in tanks and safely contained until they can also be reused or recycled.
All told, the equivalent of 8 Exxon Valdez disasters worth of hazardous fluids is reclaimed from end-of-life vehicles every year.
What is a Car Made of?
The average car on the road is a sophisticated and complex machine, made of a wide variety of different materials. This is because today’s cars must be many different things, and all at the same time. They must be:
- Pleasant to drive
- Roomy enough for everyone you need to travel with
- Spacious enough to hold everyone’s gear
- Able to sync with your phone
- Powerful enough to tow (if required)
- Able to go off-road (if required)
- And more
It takes many different types of materials to do all this!
Vehicle manufacturers put various combinations of these things into a car, as it goes down the assembly line:
- Carbon Fiber
- Foam padding
- Sulphuric acid
- Brake fluid
- Transmission fluid
- Air conditioning refrigerant
- Gear oil
- Windshield washer fluid
Cars are such recycling-rich targets because they’re made from so much metal. The US auto industry accounts for 20 percent of all domestic steel use and one third of domestic aluminum use, so making sure that metal is all reclaimed is important.
Broken down by percentages, here’s what the average car is made of:
Your car’s metal breakdown comes to 70 percent ferrous metal that includes sheet steel, steel, and cast iron and 6 percent non-ferrous metal like aluminum, copper and zinc. This is all recyclable material.
What happens when a car reaches the end of its useful life, and the recycling process is the next logical step? This amazing machine, with so many brilliantly engineered capabilities, will be broken back down into the original “elements” it was made of. Many of its parts will be reused or recycled, giving new life to both old cars and new ones. Think of it as the circle of automotive life!
What Parts of the Car CAN NOT be Recycled?
While the vast majority of every automobile can be reused or recycled, there is one by-product that has not yet made it completely into the recycling stream. That is ASR, or Automotive Shredder Residue. It adds up to 15% to 20% of the car’s content.
ASR is what’s left, after everything else of value in a recycled car has been shredded and removed, using current technology. ASR is made up of small pieces of ferrous and non-ferrous metals, fabric, glass, rubber, plastic, fluids, wood, and dirt. Some hazardous metals and chemicals like lead, cadmium, and PCBs may also be present in ASR. This has caused ASR to be classified as hazardous waste in some places, requiring special handling, and limiting recyclers’ ability to repurpose it. Half of the ASR produced ends up in landfills.
The auto industry is working with recyclers to reduce the amount of ASR and make vehicles less hazardous to the environment. Current recycling efforts have already kept 9,000 pounds of mercury out of the environment and the industry is working to get rid of the last trace amounts of mercury found in our cars.
There are ongoing efforts to find uses for ASR, as well as to separate out and recycle its non-threatening components. These efforts include:
- Using ASR as a fuel supplement in cement and steel production
- Converting it into synthetic crude oil or natural gas
- Agricultural uses
- Removing the small pieces of steel, iron, aluminum, and copper for use in recycling
- Recovering the plastics for recycling (more on this later)
What Parts of the Car Can Be Recycled?
Combine every recyclable component of a car, metal or otherwise, and you’re looking at over 25 million tons of recycled materials every single year just from end life vehicles. That’s waste and toxic chemicals that would otherwise be polluting the environment. Saying goodbye to your old set of wheels isn’t so bad when you know much of it will go on to see a new life in new products rather than sitting in a landfill.
You’ll find the metal recycled from your car used in the most unlikely of new products. It’s in the household batteries that power everything from flashlights to cameras to the wireless mouse you use to surf the Internet. Recycled automotive metal is also used in building construction and sometimes even goes right back into new vehicles. The car you get rid of today could end up being a part of the new car you end up buying tomorrow.
It’s not just the metal components of your car that can be recycled. Roughly 86 percent of a car’s total materials are eligible for recycling. Whatever is left of the old carpet, for example, can be used in air cleaner assemblies and engine fan modules. Old tires can either be reused if they’re in acceptable condition or used to make new brake pedals and floor mats. As much as possible, every last piece of an end-of-life vehicle is recycled rather than tossed aside.
A full-service automotive recycling facility will have no problem taking your entire car, breaking it down responsibly, and reusing or recycling just about all of it. But what if you’d like to do it yourself? Here’s a handy guide to recycling your own car parts, taking one part at a time.
If you are going to recycle your own car, find a safe, secure place to store all of its parts while you go through the process.
What are some other uses for recycled junk car parts?
There is a fascinating subculture made up of individuals who use junk car parts to create a wide array of objects. Some of these people create works of art, some repurpose the parts for practical but non-automotive uses, and some even use the car parts to create sculptures of cars in actual size!
Here are some examples of what people across the country and the world have done with junk cars and car parts:
Works of art:
- Carhenge in Alliance, Missouri
- “Blooming Hubcap” art
- Sculptures made from discarded tires in Morocco
- Needlepoint floral art on junk car body panels
- Horse and steer sculptures made from junk car parts in Texas
Making cars from parts:
- Supercars (and superheros) made from car parts in Poland
- Furniture made from junk classic cars
- A variety of household items made from repurposed junk car parts like those listed below can be found here and here
- Headboard made from mechanical parts
- Coffee table made from tires
- Outdoor grill made from front half of a Mini
- Hanging lamp made from aluminum wheel
- Wall clock made from hubcap
- Towel rack made from steering wheel
- Table lamp made from camshaft
- Coffee table made from engine block
- Bookends made from alloy wheels cut into ¼’s

Recycling Programs of Major Car Manufacturers
In addition to eliminating dangerous materials from cars, automakers are also using more recycled materials on their cars from the start. The milk jug you recycle at the curb could end up in a car’s trim components. The old carpet and clothing you recycle could end up being used to make sound deadening materials that keep your car quiet. Plastics from recycled bottles end up in everything from battery trays to fan shrouds to air conditioner housings.
The greatly increased environmental awareness on the part of the public has driven these companies’ desires to be seen not only as more ecologically aware, but also as contributing to the solution.
Thanks to the automotive recycling industry, materials like steel and aluminum have long been recycled into the metal products that new cars are made of. The new car manufacturers have been working on a variety of solutions to the issues of using other, not-so-easily recycled materials in the manufacturing process. This has the dual environmental benefits of requiring less new materials to be produced (reducing carbon emissions), while also creating a market for materials that might otherwise become part of the waste stream and end up in landfills. Here are a few examples:
The Ford Motor Company has made multiple efforts to use recycled materials in its production cars. These include:
- Making a total of 300 parts from materials that are renewable and sustainable.
- Using 1.2 billion recycled water bottles each year to make plastic underbody parts for its cars. Each car uses 250 bottles’ worth.
- Taking Jose Cuervo’s agave (after it has been used to make tequila) and using it for plastic parts production
- Converting a total of 300 million pounds of used airliner carpeting into car parts
- Switching to soy-based foam for all of its seats
- A plan to have its plants worldwide use 100% renewable energy no later than 2035
