Celebrate National Pollution Prevention Week 2012

Today marks the first day of National Pollution Prevention Week. Pollution Prevention Week is annually the third week of September. Pollution Prevention Week is a time when businesses, environmental groups and citizens can join forces for a common cause. By sharing information about pollution prevention, businesses can become more competitive, businesses and government can realize cost savings, and environmental quality can be enhanced.P2 Week 2012 poster

The theme for Pollution Prevention Week 2012 is “Safer Chemicals for a Safer World,” which embodies a national effort for safer alternatives to chemicals of concern. This is to ensure the safety and health of workers and communities. Using safer chemical alternatives also provides companies with a marketing edge over their competitors.

Scientists look to turning plastics into oil

On Midway Island in the Pacific Ocean, a mother albatross returns from a trip out to sea to feed her chick. Unfortunately, she has mistaken a few of the countless, small pieces of plastic in a floating island of garbage as an appropriate meal for her chick, which will die as a result.


With the negative impact of ocean-bound plastic waste, a trend of increasing gas prices, and an uncertain future in foreign oil importation, many people think changes are needed to protect both the environment and the economy.


As part of the effort to address these concerns, researchers at the Illinois Sustainable Technology Center (ISTC) are looking into the process of converting carbon-rich plastic into oil that could kill—or in this case, save—two birds with one stone. They hope that a system of creating energy out of otherwise wasted plastic material will scale back the amount of plastic waste that ends up in landfills, the oceans and other waterways as well as decrease the nation’s dependence on foreign oil.


While plastic recycling programs are prevalent in many communities throughout the United States, much of the plastic that people dispose of is mixed in with regular garbage that is bound for a landfill.


Because the base material for most plastics is petroleum, it is possible to recover a percentage of that starting material with a series of chemical reactions.


“If we cannot recycle that completely then why should we waste that carbon?” asks ISTC Senior Research Scientist B.K. Sharma, who leads the ISTC’s plastics-to-oil project.


As a way to step in and prevent this plastic waste from going out the door and into an ocean or a landfill, Sharma and other researchers at ISTC are studying one way to add another “r” to the popular phrase “reduce, reuse, recycle.” They hope to add “recover”.


In order to recover that oil, plastic must be heated to a high temperature in the absence of oxygen in a process called pyrolysis. In one of the labs at ISTC, researchers load plastic into one of the two containers of a bench-top device, seal the top and begin to apply heat.


As the temperature increases, the molten plastic material breaks down into petroleum compounds, and a gas is produced. The gas rises to the top of the container, passes through a tube and empties into some water held by the device’s second container. Here, the gas vapors condense into liquid oil. The oil is less dense than the water, so it rises to the top and can be collected.


The process can convert three types of plastics into oil—polyethylene (recycling numbers 2 and 4), polypropylene (5) and polystyrene (6).


One of the most visible uses of polyethylene is in plastic grocery bags. Whether drifting down the street or caught in a tree, these bags seem to be everywhere, creating a widespread litter problem that is very difficult to clean up.


Plastic bottle caps and yogurt cups are examples of polypropylene that can be converted into oil. However, a silicone lining is often underneath the top of the cap to prevent leaks and must be removed prior to pyrolysis. Examples of polystyrene products include Styrofoam, disposable cups, plates, cutlery, and jewel CD cases.


Sharma’s work is part of a larger body of research into the pyrolysis process, which he and other ISTC researchers have been studying for over two years. They have been using waste biomass as the starting material in much of their research, and six months ago Sharma began looking into using plastic as a feedstock.


During small-scale lab runs, one gallon of oil is produced from eight lbs of plastic, Sharma said. Although only small amounts of plastic-derived oil are being produced by ISTC research, Sharma feels that if implemented on a larger scale, the resulting crude oil can be further refined into significant amounts of energy products, such as diesel, gasoline, and jet fuel.


ISTC is a division of the Prairie Research Institute at the University of Illinois in Urbana-Champaign.

Campus food waste become campus soap

When students who produce sustainable energy generate a “waste product,” they don’t wash their hands of it. They wash their hands with it.

Members of the soap group of the Illinois Biodiesel Initiative (IBI), are experimenting with recipes to create functional and marketable soap from glycerin, a by-product of the reaction that produces biodiesel. The IBI is a registered student organization at the University of Illinois. Members are working to improve upon a sample of liquid dish soap that they gave to the Ikenberry Dining Hall earlier this year, as well as developing new soaps to sell to other outlets on campus.

The Initiative works under the guidance of Joe Pickowitz, environmental engineer at the Illinois Sustainable Technology Center (ISTC), a division of the Prairie Research Institute at the University of Illinois.

IBI is an independent division of the campus’s Engineers without Borders group. Its main project is to collect waste vegetable oil from campus dining halls every week and convert it into biodiesel. The Initiative then sells the biodiesel back to the university through the campus’s facilities and services department to use in its vehicles.
Founded in 2006, IBI has made soap production a crucial part of its goal as a sustainable student group since fall 2011. Because only about 80 percent of the biodiesel reaction’s yield is fuel, the soap group is in charge of utilizing the remaining glycerin.

In January, the soap group gave 45 gallons of liquid soap to the dining hall, which Pickowitz calls “the test bed for the whole project.” There, it was used as a prewash in the dish rooms—only a few hundred feet from where the soap’s parent oil may have been used to fry a batch of chicken wings.

The soap helped clean the dishes, but it left behind a residue on the dishes and in the dishwashing machine, said chemical engineering sophomore and Soap Production Officer Stephanie Roupas. The group is addressing this concern by testing and reformulating batches of liquid soap and said they hope to have a new batch ready for the dining hall before summer break. The soap group is preparing other samples for university housing as part of a proposal to replace the hand soap in dormitory bathrooms with a product that is sustainably manufactured right on campus.

Along with liquid soap, the group has been testing different recipes for solid soap. The form of the final soap product depends on which strong basic compound is used as a catalyst in the biodiesel reaction. While potassium hydroxide produces liquid soap, sodium hydroxide produces solid soap.

In the solids preparation lab at ISTC, Soap Research Lead Olivia Webb, who is a freshman in agricultural and biological engineering, demonstrates one problem with the solid soap. A recent batch has the consistency of Play-Doh, and it is difficult to remove samples from the pan.

“See, it’s not supposed to do that—where it’s sticking like that,” she says. “This is still useable as soap. It’s just not as marketable.”

Still working toward a perfect batch of soap, the group overcomes defects like this by carefully experimenting with new ingredients, different cooking times, and varying ingredient ratios.

Marketability may be difficult for the raw version of the soap, Webb says, because it’s brown and smells a bit like a fry cook after a day’s work. In an effort to make their product more appealing, Webb says they will re-batch the pan of bar soap to make it harder, so they are able to sell it on campus. They are also adding a scent to the sample that they will present to university housing to make it more attractive. Because most commercial dyes and scents are not sustainable, students have begun to color the soap with environmentally friendly products, such as algae, and are looking into using natural, essential oils rather than fragrances.

While they are developing their soap to be a more marketable product, Webb says they are not planning to sell it anywhere beyond campus this early in the game, as they strive for both environmental and economic sustainability.

“It would be a lot easier to start in the university so we have something to say [to consumers], ‘Our soap actually works,’” she remarks. “And it’s also easier to sell to people in the university because your shipping and packaging costs are low.”
