Crude oil pollution treatment project


Project Overview

icon-energyicon-buildingicon-waterThe Nano-CarboScavenger project supports three of iSEE’s research themes: Energy Transitions, Sustainable Infrastructure, and Water & Land Stewardship.


This project’s purpose is to optimize a Nano-CarboScavenger (NCS), a particle designed to adsorb oil and remove it from water. In Lead Investigator Dipanjan Pan’s words:

“As the demand for petroleum continues to rise, we will see an increase in petroleum transportation traffic — which will inevitably lead to an increase in chances for aqueous crude oil spills, land spills, and fracking byproduct-based pollution. These spills threaten our environment, and finding ways to clean them up has become a grand world challenge.

“But thus far, we lack efficient and safe cleanup methods for oil and petroleum spills. Typically, oil spills can affect animals and plant life in two ways: from the detrimental effect of the oil itself, and from the treatment for cleanup operations. Addressing both these challenges can help us minimize overall impacts to the ecosystem and facilitate a much quicker recovery.

“In response to this ecological threat, my team has developed a highly efficient, environmentally friendly, bio-digestible, and commercially amenable powder dispersant. This tiny, nanometer-sized agent is uniquely “dual functioning” — for simultaneous collection and removal of crude oil and petroleum distillates with remarkable efficiency. More importantly, this agent does not leave any residual footprint because it is degraded in the environment and in living systems — and any incidental biological uptake is not harmful to living organisms.

“Our reusable Nano-CarboScavenger powder dispersion leads to clumping and accumulates the oil for simple recovery by nets or booms. That makes our approach distinctly different from current approaches and introduces an ecologically compliant strategy for oil spill remediation.

“At the University of Illinois, this multidisciplinary project employs bioengineers, materials scientists, and analytical chemists to help solve a prevalent issue affecting the Earth’s environment.”

Project News

The Crude Oil Pollution Treatment Project team recently published a paper announcing its work on the Nano-CarboScavenger (NCS), which promises an environmentally friendly solution to aquatic oil spills around the world.

The NCS powder simultaneously diffuses oil floating on the water’s surface for natural breakdown and absorbs oil and traps it for easy removal. Pan recently reported results in an article in Nature Publishing, a publication of Scientific Reports. Most methods for oil cleanup today rely on releasing toxic chemicals into the ecosystem, but the NCS particle leaves fish and other aquatic life, as well as humans, unharmed.

In laboratory tests, researchers removed more than 80 percent of oil contamination they introduced into water samples by sprinkling NCS powder across the surface of the water and scooping out clumped oil. The total cleaning effect will be even higher in natural bodies of water, where millions of microorganisms can gobble up oil molecules NCS particles disperse into the water.

PI Dipanjan Pan reports that the team is “totally in line with our proposed timeline for reaching all the milestones.” Specifically …

  • The team’s manuscript on Nano-CarboScavengers rehabilitating petroleum-contaminated water has been reviewed twice with Nature Communications, and another revised version is ready to be submitted.
  • Significant research progress has been made — and key data collected — to take the project beyond the level of proof of concept. New student members have been added to the team (see those updates below).
  • And new research directions have been identified — and progress has been made in those directions. They include:
    • “Utilizing our platform technology based on carbon nanoparticles, we are proposing a novel ‘smart water purification system’ for remediation of pharmaceuticals, hormones, polyaromatic hydrocarbons and other contaminants,” Pan said.
    • A second project is looking at production of mineral-rich algal nanoparticles from biomass (algae) for agricultural, biomedical and environmental (metal, e.g. mercury scavenging) application.
    • “A third spinoff project is looking at a self-‘reproducing’ bacterial-nano-enzyme architecture for novel solution of biofuel production,” he said.
