Yogurt pots, shampoo bottles, coffee-to-go lids, bubble wrap — plastic products are all composed of the same building blocks: long carbon chains.
Heating them to high temperatures makes the carbon chains crack into a mixture of shorter molecules, ultimately converting them back into crude oil, the resource from which the majority of plastic products were originally made.
Big Business<p>Several companies have made significant investments in chemical recycling, building facilities to test various ways of making what is allegedly more environmentally friendly oil. So far, it's still in the development and test stage.</p><p>In 2018, multinational chemistry giant BASF launched ChemCycling — a project that aims to generate a so-called pyrolysis oil from plastic waste. The company claims it can be used in the production of new polymers, which it says will save fossil fuel resources.</p><p>Austrian oil and gas company OMV has built a pilot plant which it says can process all common packaging material such as polyethylene, polypropylene and polystyrene.</p><p>The plastics are chopped down, mixed with a high-boiling solvent and heated in a furnace at over 300 degrees Celcius (572 degrees Fahrenheit). Once the product has been distilled and the solvent filtered off, the company is left with synthetic crude oil, which it claims is "free of sulfur, lighter than fossil crude oil and with a higher hydrogen content — therefore of higher quality."</p><p>The product can be refined to make fuels such as gasoline, kerosene and diesel or petrochemical products.</p><p>The plant has the capacity to convert 100 kilos of waste each hour, OMV told DW. But a planned successor facility would be able to process 2,000 kilos hourly.</p><p>Similar pilot plants are being constructed in other countries across Europe.</p>
Behind the Hype<p>So, can chemical recycling solve our waste problem through the creation of fuels?</p><p>Roman Maletz, a researcher at the Institute of Waste Management and Circular Economy at the Technical University in Dresden, is not convinced.</p><p>The idea of recycling plastic trash by cracking it, he says, is neither new nor revolutionary. It has just never worked before.</p><p>"In the past, such plants always ran into problems when in continuous operation," Maletz said. "I don't see how these issues could suddenly be resolved."</p><p>Problems arise when the trash contains too many different materials or when it is too dirty.</p><p>"In that case, the quality of the product is lowered, and the whole process becomes economically unviable."</p>

The Montreal Protocol of 1987 committed nations around the world to stop using the chlorofluorocarbons (CFC) that created a hole in the ozone layer. While it stands as one of the most effective environmental commitments the globe has seen, new research shows the side effects have been costly as chemicals dangerous to human health build up in the environment, as the BBC reported.
