What You'll Learn
Use a heat gun or oven to melt plastic
Melting plastic at home is generally safe and accessible. Using a heat gun or oven to melt plastic is one of the easiest ways to do it.
Using an Oven
Place the plastic in a heat-proof container, such as a cheap sheet pan or a ceramic tile, making sure that the plastic does not spill on the oven surfaces if it becomes totally liquid. Preheat the oven to around 300 °F (149 °C). This temperature will gradually melt the plastic, so be patient with the melting process. Open some nearby windows and turn on your oven's fan while the plastic melts to get rid of any toxic fumes.
Using a Heat Gun
Purchase a heat gun from a home improvement or hardware store, or online. Place the plastic on a heat-proof surface, like a metal sheet or concrete block, outside. Turn on the heat gun and hold it about an inch away from the plastic, moving it slowly and evenly over the area you want to melt. Make sure to move the heat gun evenly across the plastic surface so that it melts evenly. You can also use a lighter if a heat gun is out of your budget.
Using Hot Water
Heat water in a pot or pan to above 150 degrees F. If the water is boiling, allow it to cool to prevent possible injury. Place the plastic in the hot water to soften. If you prefer to melt only part of the plastic, you can cut it with scissors. When the plastic turns clear, it is soft enough to form and mold.

Avoid toxic fumes by melting HDPE or LDPE
Melting plastics at home is generally safe and accessible. However, it is important to take precautions to avoid toxic fumes, especially when melting High-Density Polyethylene (HDPE) or Low-Density Polyethylene (LDPE). Here are some ways to avoid toxic fumes when melting these plastics:
Use a Suitable Container
Place the plastic in a heat-proof, non-plastic container, such as a metal or glass container that won't be used for food. This prevents the plastic from contaminating the container and vice versa.
Choose the Right Oil
Instead of melting the plastic directly in an oven, consider using oil or wax as a heat transfer medium. Oils with a high smoke point, like canola oil, are recommended as they are more stable and less likely to oxidize. However, be cautious when disposing of oil contaminated with plastic, as it may be challenging.
Maintain Temperature Control
Use a device with temperature control, such as a deep fryer, to heat the oil or wax. The ideal melting temperature for HDPE is between 176°C and 260°C, while LDPE melts at around 248°F. Be cautious not to exceed these temperatures to prevent the release of toxic fumes.
Work in a Well-Ventilated Area
Even with proper temperature control, it is advisable to work in a well-ventilated area or outdoors to avoid inhaling any potential fumes. If possible, wait for warmer months when ventilation is easier.
Consider Alternative Methods
Instead of melting HDPE or LDPE, you can mix small amounts of these plastics with paraffin to create a carvable and machinable wax. This method eliminates the need for melting plastic and reduces the risk of toxic fumes.
By following these precautions, you can minimize the risk of toxic fumes when melting HDPE or LDPE. Remember to always work with caution and refer to Material Safety Data Sheets for specific information regarding these plastics.

Melt plastic in oil or wax
Melting plastic in oil or wax is a great way to give plastics a new lease of life. It is possible to melt plastic at home, but it is important to take care and use the right type of plastic. LDPE (low-density polyethylene), which is commonly used for plastic bags, has a melting point of 248°F. This is lower than the boiling point of cooking oil, which is around 350°F, so a low-viscosity oil like canola oil is a good option.
To melt plastic in oil, you can use a double boiler. Fill the bottom half of the boiler with oil and place it on a heat source. In the top half of the boiler, place your plastic, making sure it is in a heat-proof container suitable for non-food use, such as an old pot. Turn on the heat source and let the oil heat the plastic until it melts. You can also use wax instead of oil if you want a smoother, non-oily finish.
It is important to note that melting plastic can release hazardous fumes, so it is recommended to work outdoors or in a well-ventilated area and wear a respirator. Always take precautions when handling hot oil or wax, as splashing can cause serious burns.
Another option for melting plastic is to use a heat gun, which can be purchased from hardware stores or online retailers. Place the plastic on a heat-proof surface like a soldering block, metal sheeting, or concrete blocks, and use the heat gun on a low setting to evenly heat the plastic.
If you want to melt plastic in an oven, preheat it to around 300°F (149°C). Place the plastic in a heat-proof container that will catch any melted plastic, such as a cheap sheet pan or a ceramic tile, and put it in the oven. Keep a close eye on the plastic to avoid burning it, and remove it from the oven as soon as it has melted.
Remember to always test a small piece of plastic first to ensure it melts safely and does not disintegrate.

Use enzymes to break down polymers
Enzymes are the workhorses of biochemistry that speed up reactions and can be used to break down polymers. The process, known as biological recycling, involves using enzymes to break down plastic polymers into their subunits, called monomers. These monomers can then be used to make new plastics, creating an "infinite recycling" loop.
Recent evidence shows that some microbes are learning to work on petroleum-derived polymers. For example, in 2016, Japanese scientists discovered a bacterium that eats polyethylene terephthalate (PET) in samples taken from a recycling plant. This inspired researchers to search for plastics-degrading microbes, and more are being found.
Another example is the discovery of waxworms eating holes in polyethylene bags by Federica Bertocchini, a molecular biologist at the Spanish National Research Council (SNRL). Scientists are also scouring landfills, auto wrecking yards, and other sites for organisms that can break down plastics.
In a small-scale demonstration, researchers used an engineered version of an enzyme found in a compost pile to break down PET into its subunits. Some of these subunits were then fed to another microbe that can make either the biopolymer PHA or an intermediate building block.
French company Carbios is also working on breaking down polymers with enzymes. They are building a recycling plant in Longlaville, France, expected to begin production in 2026. The facility will use enzymes to convert 50,000 metric tons per year of PET into its raw materials: terephthalic acid and ethylene glycol.
Additionally, scientists have created a super-enzyme that degrades plastic bottles six times faster than before. This enzyme was engineered by linking two separate enzymes found in the plastic-eating bug discovered at a Japanese waste site in 2016. The super-enzyme could be used for recycling within a year or two, enabling the full recycling of bottles and potentially mixed-fabric clothing.

Use acetone to dissolve plastic
Acetone is a solvent that can be used to dissolve some types of plastics. It is easily available at hardware and beauty supply stores, as well as online. It is important to use pure acetone as it works better than a mixed solvent solution for dissolving plastic.
Firstly, determine if the plastic can be dissolved by acetone. Do a test by placing a small amount of acetone on the plastic you want to melt. If the acetone melts the plastic, it will occur on contact. For example, acetone works well to melt ABS plastic and Styrofoam.
Next, put the plastic in a non-plastic container, as acetone dissolves plastic and you want to ensure the container is not dissolved. Metal or glass containers that won't be used for food are suitable.
Afterward, pour the acetone into the container with the plastic. The acetone will surround the plastic molecules, breaking down their structure. The plastic molecules will then be surrounded by the liquid acetone solvent and will be able to move about.
When the acetone evaporates, the plastic molecules will be attracted to each other again and will harden. The plastic will assume the shape of the container it was in.
It is important to note that the kind of plastic you want to dissolve matters. Different plastics have different structures, substructures, and properties like solubility. Acetone may dissolve some plastics while simply drying out others.
