Student Researchers Transform Waste Plastic Into an Alternative Fuel

Student researchers at Northeastern University have designed an apparatus to convert plastic waste into clean energy without releasing harmful emissions.

Under the leadership of Yiannis Levendis, distinguished professor of mechanical and industrial engineering, a team of undergraduate and graduate engineering students developed a waste combustor, which breaks down non-biodegradable plastics to create an alternative source of fuel.

Their prototype was featured at the fifth annual MIT Energy Conference this past March. The team worked for nine months on the research, which, for the undergraduates, was their senior capstone project.

Self-sustainability is the key to the double-tank combustor design. Plastic waste is first processed in an upper tank through pyrolysis, which converts solid plastic into gas. Next, the gas flows to a lower tank, where it is burned with oxidants to generate heat and steam. The heat sustains the combustor while the steam can be used to generate electric power.

“The prototype can be scaled up to drive a large power plant, which could connect to a plastic recycling center for a constant flow of fuel,” said David Laskowski, an undergraduate student working on the team.

Levendis, who has pursued research on the combustion of plastics and other post-consumer wastes for the past 20 years, is currently focusing on the concept of vaporizing solid plastic waste, which would reduce levels of harmful emissions during the combustion process.

“The inspiration behind my research is the quest to develop clean, cost-efficient power sources in the face of dwindling fossil fuel reserves,” Levendis said. “It will also help get rid of unsightly, non-biodegradable plastic waste that cannot be recycled.”

According to Laskowski, calculations show that the new technology has the potential of replacing up to 462 million gallons of petroleum in the United States alone, if all recycled plastics were to be processed.

“We are currently consuming highly-priced conventional premium fuels (to produce electricity). The fuel developed using this system will lower the cost of electricity for future generations,” Levendis said.

The team members included Jeff Young, Shane McElroy, Jason Lee and Paul Conroy, all senior undergraduate students; and Brendan Hall and Chuanwei Zhuo, who are graduate students.

With the success of their prototype, Hall and Zhuo plan to continue working with Levendis on further development of the project.

Im Focus: Space observation with radar to secure Germany's space infrastructure

Satellites in near-Earth orbit are at risk due to the steady increase in space debris. But their mission in the areas of telecommunications, navigation or weather forecasts is essential for society. Fraunhofer FHR therefore develops radar-based systems which allow the detection, tracking and cataloging of even the smallest particles of debris. Satellite operators who have access to our data are in a better position to plan evasive maneuvers and prevent destructive collisions. From April, 25-29 2018, Fraunhofer FHR and its partners will exhibit the complementary radar systems TIRA and GESTRA as well as the latest radar techniques for space observation across three stands at the ILA Berlin.

The "traffic situation" in space is very tense: the Earth is currently being orbited not only by countless satellites but also by a large volume of space...

Im Focus: Researchers Discover New Anti-Cancer Protein

An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.

The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...

Im Focus: Researchers at Fraunhofer monitor re-entry of Chinese space station Tiangong-1

In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.

Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...
