Ricardo And Recycling Technologies’ New Plastic Waste Project

Ricardo and Recycling Technologies have announced they are to begin work on a new project to characterise plastic waste derived clean fuel.

Recycling Technologies has developed a machine (the RT7000) and is industrialising a process to convert residual plastic waste into a low sulphur hydrocarbon compound known as PlaxxTM. Ricardo’s role will be to assess the relative performance of PlaxxTM, HFO and diesel when used in an engine of the type and scale typical of power generation or marine propulsion applications using its Ricardo Atlas II research engine.

Recycling Technologies’ PlaxxTM fuel is created from residual mixed plastic waste that is not amenable to direct recycling and would otherwise go to landfill. The next stage is to characterise the use of this recycled, low sulphur fuel as a substitute for fossil based heavy fuel oil (HFO) and diesel. It can be used as a petrochemical feedstock, a manufacturing commodity such as paraffin wax, or as a clean and more sustainable fuel substitute for fossil-based HFO, which also displaces imported oil.

The companies explained that in the European Union alone, more than 25m tonnes of post-consumer waste plastic is produced each year. Of this huge quantity of material, only 26 percent is recycled, with 36 percent going for incineration, while the remaining 38 percent contributes to the ever expanding problem of landfill. In addition to the loss of its material value, the carbon cost of processing this mixed waste is considerable, not least due to transportation, as many regions and states export their mixed plastic waste due to a lack of localised processing facilities.

In the project announced today, Ricardo will work with Recycling Technologies to assess the relative performance of PlaxxTM, HFO and diesel when used in an engine of the type and scale typical of power generation or marine propulsion applications. The Ricardo Atlas II research engine will be used for this work: this advanced test engine is capable of efficiently evaluating the performance of fuels in large, multi-cylinder engine designs ranging from 150-200 mm bore and representing engines in the class 0.5 to 5 MW, in a single power cylinder. This can result in a reduction exceeding 90 percent of the test fuel consumed in a typical research or development project.

“Finding solutions to landfill diversion is a critical challenge facing modern society,” commented Dr Adam Read, Ricardo Energy & Environment practice director for resource efficiency & waste management. “The ability to generate fuels and recover plastics is key to the sustainable management of the world’s resources. As such, assessing the viability of the process during the pilot phase is an exciting and potentially ground-breaking step for Ricardo and the team from Recycling Technologies.”

Adrian Griffiths, CEO Recycling Technologies commented: “The marine industry is a key market as the use of high sulphur oil is increasingly being restricted. Working together with Ricardo on this project, we are now taking steps to get Plaxx™ qualified so that it is fit for use in medium and large marine engines. Plaxx™ is an ultra-low sulphur feedstock and can be adapted for use in any markets where crude oil derivatives are used. Through this pilot project, we hope to qualify Plaxx™ as meeting the new global MARPOL requirements.”

Recycling Technologies has funded its extensive R&D projects through various government funding organisations, including the Knowledge Transfer Partnerships (KTP) and the Energy Catalyst grant with the University of West England (UWE), funded by Innovate UK. There has been additional support from other government funding organisations, such as the Department of Energy and Climate Change (DECC) and the Department for Business Innovation and Skills.
