The recycling of a single aluminum can save the same amount of energy present in a half-gallon of gasoline, according to the website A Recycling Revolution. Imagine how much energy recycling an aluminum engine block would save. Post-consumer scrap, such as car parts, accounts for the largest volume of aluminum available for recycling, but may be difficult to recycle because of contamination from oils, refrigerants, or paints. Recycling an aluminum engine block requires locating a scrap metal recycler that specializes in post-consumer scrap.
Evaluate the engine block to determine if it is only aluminum or if it is a mixture of aluminum and iron or steel. Use the magnet test if you are unsure. Place a magnet on various parts of the engine block. If the magnet sticks anywhere, it is not an aluminum part and may need to be removed.
Locate aluminum or scrap metal recyclers in your area. Use the phone book or a website such as Earth911. Not all recyclers take engine blocks because of the oil contamination. Those that take engine blocks may reduce the sale price because of the contamination. Verify if the recycler will take mixed-metal engine blocks or if you will have to remove any steel or iron parts first.
Drain the motor oil from the engine block. Collect the motor oil in a clear plastic container and label it "used motor oil." This motor oil can be recycled as lubricant for other equipment or taken to a local motor oil recycler. The automotive industry encourages repair shops to accept used motor oil for recycling. However, the shops are not obligated to accept it. Call your local hazardous waste management facility for drop off locations.
Transport the aluminum engine block to the recycling facility. For safety, have a buddy help you load the engine block. Secure the engine block with ties to keep it from shifting during transport. If using a car trunk, place a tarp in the bottom of the trunk to prevent oil from staining the inside.
