Cleaning the Air: UPH Industrial Engineering Turns Styrofoam Waste into Innovative Air Purifier
Styrofoam is one of the most non-degradable forms of plastic, taking centuries to break down in landfills. To help solve this problem, Universitas Pelita Harapan’s (UPH) Department of Industrial Engineering has developed a prototype that recycle discarded styrofoam waste into a high-tech air purifier. Designed specifically to combat urban air pollution, this innovative device targets dangerous particulate matter, specifically PM 1, PM 2.5, and PM 10, which are microscopic particles commonly emitted by vehicle exhaust that can easily penetrate our lungs.
What makes this purifier interesting is how it generates power. It utilizes a technology called a triboelectric nanogenerator (TENG). TENG is a specialized energy-harvesting device that converts simple mechanical energy, like everyday ambient vibrations, motion, or pressure, into electrical energy. By using discarded styrofoam as the core material to trigger this static-electricity effect, the device generates its own filtration power from the movement around it, creating a highly sustainable, self-powering system.
The prototype’s initial testing has yielded incredibly promising results. Even in its early stages, the device successfully filtered out >65% of PM particles from the air. While the research team notes that the prototype still requires further modification and fine-tuning before it can be mass-produced, this breakthrough stands as a powerful testament to UPH’s commitment to circular economy solutions, proving that yesterday’s waste can become tomorrow’s clean air technology.
