Leftover Styrofoam: From Waste to Treasure with These Ingenious Reuse Ideas
Styrofoam, also known as expanded polystyrene or EPS, is a widely used material in product packaging due to its lightness and ability to protect objects from impacts and damage during transport.
However, once it has served its purpose, it often becomes a problematic waste due to its low biodegradability and volume, taking up space in landfills and generating negative environmental impacts. Fortunately, there are ingenious and environmentally friendly alternatives to reuse leftover Styrofoam, turning it from waste into a true treasure.
Thick Styrofoam paste:
Dissolving polystyrene in gasoline allows you to obtain a dense and malleable paste similar to paint, which can be used for various craft and modeling projects. Here are the steps to carry out this process:
Gather the leftover Styrofoam: Collect the Styrofoam scraps you want to reuse. These can be leftover packaging, food trays, disposable cups, among others.
Safety precautions: It is important to carry out this process in a well-ventilated area and away from heat sources or open flames. Gasoline is a very flammable liquid.
Crush the Styrofoam: To facilitate dissolution, crush the Styrofoam into small pieces or grates using a blade or grater.
Dissolution in gasoline: Place the Styrofoam pieces in a sturdy container and pour enough gasoline to cover them completely. Let the polystyrene dissolve in the gasoline for several minutes, stirring occasionally to speed up the process.
Obtaining the paste: Once the polystyrene has completely dissolved, you will have a thick, malleable paste. It can be molded or used to fill gaps and cracks in various craft projects.
Clear Styrofoam Varnish:
In addition to the thick paste, polystyrene can also be dissolved in acetone and universal polyurethane thinner. You can obtain a clear varnish, which can be used to protect and finish different surfaces. Here are the steps to create this varnish:
