The Illinois Sustainable Technology Center (ISTC) at the University of Illinois Urbana-Champaign and Purdue University have diverted almost six tons of waste from landfills through a recycling program that turns used lab gloves and garments into shelving, flowerpots and lawn and garden furniture.

Both institutions were looking for ways to reduce their solid waste streams and enhance their sustainability efforts. They found it in a program called RightCycle by Kimberly-Clark Professional, the first large-scale recycling program for non-hazardous lab and industrial waste.

Since its inception in 2011, RightCycle has diverted more than 350 metric tons of waste from landfills. In its first year, it diverted two tons of waste. The number of customers participating in the program has significantly increased, from just a handful at the start to almost 200 as of July 2016. Kimberly-Clark Professional is continuing to expand the program – bringing it to Western Europe and exploring expansion into other regions.

"We pioneered this program because we recognized that the sustainability goals of our university and pharmaceutical customers included reducing landfill waste, and single-use gloves accounted for a large percentage of that waste," Randy Kates, director of the Kimberly-Clark Professional Global Scientific Business, said in a statement. "We needed to find a recycling solution that helped them achieve their goals and enabled their people to be positively engaged in the process."

RightCycle removes gloves, masks, garments, shoe covers and other apparel accessories from the waste stream and turns them into plastic pellets. These are then used to create eco-responsible consumer products and durable goods, such as lawn furniture, flowerpots and planters, shelving, totes and storage bins.

The Illinois Sustainable Technology Center (ISTC) is a division of the Prairie Research Institute at the University of Illinois Urbana-Champaign. Its mission is to drive statewide economic growth through sustainability. To fulfill that mission, ISTC conducts scientific research and, in the process, uses a lot of gloves.

"We conducted a waste audit to see how we could go to zero waste in our own building and realized that gloves were about 10 percent of our total waste by weight," Shantanu Pai, ISTC assistant sustainability researcher, said in a statement. "We were already effectively recycling other items – glass, aluminum, paper and cardboard."

With RightCycle, ISTC was able to reach 89 percent compliance for gloves in its labs. It then decided to take the program a step further, piloting it in the University's main dining hall and achieving an estimated diversion rate of 90 percent. It is in the process of expanding the effort to all dining facilities and campus labs. In fact, the university has purchased a storage container to house the gloves, so that shipments can be made just once a year.

Since implementing the RightCycle program in 2013, the Center and the University have diverted 4,945 pounds, or approximately 320,480 gloves, from landfills.

It had similar success at Purdue University, which uses approximately 360,000 disposable gloves annually.

In 2014, Purdue University added glove recycling to its list of sustainability accomplishments, when it adopted the RightCycle program. Since November 2014, the chemistry department at Purdue University has diverted 6,862 pounds of lab gloves from landfills, or approximately 444,718 gloves. Michael Gulich, director of campus master planning and sustainability, is looking to expand the program to other campus labs as well as food preparation areas.

"Once you address cans, bottles, paper and cardboard recycling, you get into smaller niche streams," Gulich said in a statement. "We have some addressed very well, such as electronics waste and landscape debris. Previously, gloves didn't have a solution. Anything that increases our diversion rate is good."
