Co-processing is a way to convert plastic waste into something useful. At the same time, it is a more environmentally friendly disposal method of plastic as compared to landfilling or incineration. It works by using plastic waste in industrial processes as alternative fuels or raw materials. In other words, the waste is responsibly and efficiently burned in a high-temperature cement kiln so it can be used as fuel with minimal carbon emissions. Through this, energy and materials from the plastics are sustainably recovered and can be used for new products that support a circular economy.
