Instructables explains that aluminum cans can be melted using a propane torch. A steel drum or a canister is needed to act as a crucible, which should be insulated and stabilized by sand. For maximum safety, all the work should be done outside on a flat, fire-retardant surface.Continue Reading
Before starting the project, it is necessary to check for all the tools and materials needed, which include safety goggles, fire-retardant welding gloves, pliers (or alternative safe tool for lifting the hot crucible), a cupcake tin, a safe canister for residue and a steel ladle.
Start by crushing the cans, making them as compact as possible. Add a crushed can to the crucible, and place the torch over it until it melts. Once the first can has melted, further cans can be added to the crucible. Additional cans will melt quicker, as the molten aluminum adds to the heat created by the torch. A residue will form on top of the molten metal; this is the paint and other coating elements from the cans. Use a ladle to remove it, and place it somewhere safe to cool.
When finished melting all the cans, lift the crucible, and pour the liquid aluminum into the cupcake tin. Once cool, the resulting aluminum blocks, or ingots, should be easy to remove and can be used for metal working projects.Learn more about Sustainability
Propane usage depends on the nature of use, such as appliances, furnaces and fireplaces, as well as the climate. Each gallon of propane provides 91,547 British thermal units, or BTUs. Appliances can vary a great deal from about 25,000 BTUs per hour to more than 400,000 BTU per hour.Full Answer >
Cans, foil and cookware are recyclable aluminum items. Beverage cans are the primary aluminum cans recycled, and recyclable cookware consists primarily of disposable aluminum baking and cooking vessels. Less common aluminum items that can be recycled are window frames, wire, tubing and electronics.Full Answer >
Some important things to recycle are aluminum, plastic bottles and glass. Appliances and other objects that contain steel are also important to recycle because recycling steel saves energy and conserves natural resources.Full Answer >
Ways to recycle pop tabs include collecting and dropping them off at local aluminum recycling plants, using a curbside collection service, or taking them to a local recycling center. Pop tabs are made of aluminum, one of the easiest metals to recycle, and are often collected exclusively by charities and nonprofits due to their convenient size and ease of access.Full Answer >
