Polyethylene (PE), polypropylene (PP), and polystyrene (PS) are commonly used plastics that can be effectively converted into fuel. These plastics are then sent to specialized facilities where they undergo a thermal treatment process.

The conversion process typically involves pyrolysis, a thermal decomposition technique. In this process, the plastics are heated in the absence of oxygen, causing them to break down into smaller molecules. This results in the formation of syngas (synthetic gas), which primarily consists of carbon monoxide and hydrogen. The syngas can be further processed to produce various fuels, including diesel, gasoline, and jet fuel. This approach not only reduces the volume of plastic waste but also generates a valuable energy source.

One of the key advantages of plastic-to-fuel conversion is its ability to address the issue of plastic waste management. Switzerland, like many countries, faces challenges in managing plastic waste, especially single-use plastics. By converting these plastics into fuel, the process reduces the reliance on landfilling or incineration, which can have environmental impacts. Instead, the waste is transformed into a resource, providing a more sustainable and circular approach to plastic recycling.

The technology behind this conversion process has been developed and refined over the years, ensuring its efficiency and environmental benefits. It is an energy-intensive process, but the energy generated can be utilized within the facility or fed back into the grid, contributing to a more sustainable energy cycle. Additionally, the conversion process can be tailored to produce specific fuel types, allowing for customization based on market demands and energy requirements.

In summary, plastic-to-fuel conversion is a promising recycling method in Switzerland, offering a unique solution to plastic waste management.
