Herbold washing plant gets to the heart of PP hard plastics
The primary production of one metric ton of polypropylene – the world’s second most widely used plastic – requires some 5.2 metric tons of raw materials and releases 1.7 metric tons of greenhouse gases. By contrast, the use of one metric ton of polypropylene from secondary raw materials, such as plastic waste, results in only around 225 kilograms of resource consumption and just under one metric ton of greenhouse gases.
