Chemical recycling at Mura Technology Ltd

New technology recovers resources from plastic waste within 30 minutes

The problem: Eight million tonnes of plastic end up in the world's oceans every year. These lost resources are worth around $80 billion. Up to now, most plastic has been incinerated and only 14% recycled. Around the world, mixed waste is always left over. In the case of non-technical plastics, it is 100 to 1,000 times the amount.

The solution: In 2007, Mura Technology Limited developed a new form of chemical recycling and tested it for over ten years in a pilot plant in Australia - the so-called Hydrothermal Plastic Recycling Solution (HydroPRS). This solution has since been renamed HydroPRT, which stands for Hydrothermal Plastic Recycling Technology.

HydroPRT makes it possible to convert conventionally non-recyclable plastic waste back into oil within 30 minutes. The method is much more resource-efficient than extracting fossil oil, as it saves up to five barrels of oil per ton of plastic waste processed. Only water, high temperatures and pressure are used to separate the cells and join them together again. One plant alone can process 20,000 tons of plastic per year, reducing CO2 output by 28,180 tonnes. That is the annual consumption of 5,983 cars and the annual energy needs of 4,914 households. The plant's capacity, however, is to be tripled in the long term.

Since April 2021, Dow Chemical, the world's second-largest chemical company, has been another partner. The collaboration will further advance the scaling of Mura's cutting-edge recycling process. Dow will use the newly extracted raw materials to develop new plastics for food packaging and other packaging products that will eventually be recycled back into global supply chains.

The process is planned as follows: waste companies supply the plastic waste to achieve their recycling goals. Oil is then obtained at a price similar to that of fossil oil. In the first phase, a total of four catalytic hydrothermal reactors will be built in Teesside to process more than 80,000 tons of plastic waste every year. In addition, further plants are planned in Germany, the USA and Asia, among other places.
