Plastics are highly durable and versatile, making them essential in modern life, but they also cause serious environmental problems due to their resistance to breaking down naturally. The buildup of plastic waste in landfills, rivers, and oceans leads to pollution that harms ecosystems and human health. While existing methods for degrading plastics often require high energy and expensive equipment [1], we developed a cost-effective atmospheric cold plasma device (Figure 1a) as an alternative technique to degrade plastic based on Tesla coil principles. The tesla coil serves as an electrical transformer to increase the voltage from a low input of 12-30V to an output of 3-7.5kV. The primary coil has 4 turns of AWG #26 magnetic wire, and the secondary coil has 1,000 turns of AWG #36 magnetic wire. A pipette nozzle was designed to fit gas hoses tightly, preventing leaks, and with an output diameter that produces a plasma jet approximately 5mm wide, ideal for plastic (e.g. macro, micro) degradation [2]. To generate cold plasma, we utilize oxygen and nitrogen gases. The design and setup are shown in Figure 1a. Figure 1b represents the actual photo of plasma discharge. These photo shows that our atmospheric cold plasma device can generate cold plasma and can be used for degradation of plastics.
