TAMPA, Fla. – University of South Florida scientists have developed a natural, non-toxic and renewable system to purify water using cactus mucilage. This novel and patented technology was exclusively licensed from USF to Clean Water by Nature, LLC, to develop and commercialize products and processes to purify water.

The innovative technology is based on research conducted at the University of South Florida by Norma Alcantar, Ph.D., professor, Department of Chemical & Biomedical Engineering at USF. Alcantar and her team found that mucilage (extract) from the common and easily grown prickly pear cactus (Opuntia ficus-indica) has the potential to treat ground/surface water, well water, and waste water to EPA maximum contaminant level standards.

Using simple, green methods and readily available resources, cactus mucilage filters nonpotable water while it removes sediment, heavy metals, parasites, and bacteria. According to Alcantar, the scientific advantage of this technology comes from the processing and use of cactus mucilage, a plant-based substance that is easily farmed, naturally occurring and 100% sustainable. Cactus mucilage is an approved substance by the FDA, the USDA, the EPA, and other government agencies.

The licensing agreement between USF and Clean Water by Nature, LLC provides the company worldwide, exclusive rights to developing granulated filters and nano-fiber filters manufactured from cactus mucilage and processes for using these filters to purify water. According to Alcantar, using cactus mucilage to treat water provides a safe purification alternative to the current processes that use various types of toxic chemicals including Ferric Sulfate, Aluminum Sulfate and Sulfuric Acid to remove the suspended particles from raw water sources.

The company and USF researchers have formed a team for the NSF I-CORPS program, where they hope to gain a better understanding of the customers, markets and valuation proposition of the inventive technology.

"We are very excited to participate in the I-CORPS program and get the training and tools to help transform our technology," said Alcantar. "We anticipate the results being the identification of an efficient path to commercialization."

"We are honored to be working with USF and Dr. Alcantar and her team," said P. Kathleen Lovell, chief executive officer of Clean Water by Nature. "Water quality and scarcity have been labeled, 'The Defining Crisis of the Twenty-First Century.' We are running out of fresh water, and we must find ways to recycle used water and return it to the drinking supply in a green and affordable way."

Lovell has over 30 years of entrepreneurial experience including building high-growth entrepreneurial ventures and in manufacturing operations with Bristol-Myers Squibb. As CEO and founder of Powers Device Technologies, Inc., Lovell successfully commercialized a technology and has served as a mentor and judge for Startup Quest® programs in North Florida. She has also served as managing director of Powers-AD Investment Group, LLC, an angel-fund providing consulting and entrepreneurial services to early stage companies and has been involved as chairwoman and member of the Emergent Growth Fund.
