My Story

Mr. Fretz' passion for uniting industry and the environment began where he grew up on a farm in Ontario, Canada. This location is at the base of the Niagra Escarpment, which is registered as one of the world's well-known biospheres.  At that time, little was known about the environmental consequence of the exposure to toxic waste.  After recovering from a life-threatening illness caused by contaminated soil and water on his family’s farm, Mr. Fretz began his life’s mission and passion to protect others from the same health consequences that he suffered.

Mr. Fretz launched his environmental career with Internationally known, Browning-Ferris Industries (BFI) Canada.  It was here that he was trained to manage both large and small waste management clients with integrated recycling programs.  One notable program was the Vancouver International Airport. Beginning in Vancouver, Mr. Fretz pioneered an organics diversion program that quickly becoming the new mandate in the United States.  

In 1993 Mr. Fretz immigrated permanently to the United States and accepted a position with BFI’s newly formed, organics division in Irvine, California.  He was instrumental in the implementation of the first commercial organics diversion program.  The program was designed to manage organic waste and conserve space in California's overburdened landfills.  This program was the prelude to what would later become the commercial organics industry that we see in supermarkets today.

After concluding his tenure with Browning Ferris Industries, Mr. Fretz endeavored to create his own organic materials research and development company, Greenways Environmental.  It was here that he developed a line of novel horticulture and agricultural products.  Unlike traditional products in the marketplace, Mr. Fretz specially designed products that provided uncommon benefits, such as disease suppression, water conservation and soil enrichment.  These new products also encourage biological diversity that protect and improve the environment.

These organic products were widely distributed in multiple states, by internationally known companies, like John Deere and Helena.  These products have successfully been used by CalTrans, farms, such as Green Paradise Farms in California and hundreds of landscape companies, including the largest integrated landscape service provider in the world, Valley Crest and Brightview Landscape Companies.  Kevin designed and distributed products that were specified as

The Blue-Ribbon Standard in Orange County California, the Rose Bowl in Pasadena, the Wynn Resort, MGM Grand, Bellagio, and Mirage resorts in Las Vegas, the cities of Los Angeles, San Bernardino, San Jose, San Juan Capistrano, and Las Vegas.  Kevin also designed a regenerative, closed-loop waste and recycling system for Rossmoor Leisure World in Walnut Creek, CA.  This project demonstrated over a 50% irrigation surplus, proven through a pilot project that also created a budget surplus with their waste recycling program.  

Mr. Fretz founded Green Earthology, Inc. in 2016.  This is our consulting company was established to address industry’s environmental challenges with profitable environmental solutions.   In 2022, Patriot Green Products, LLC was founded as the sales arm of Green Earthology, Inc.  We look forward to improving our clients' bottom line.

Mr. Fretz is a sought-after public speaker in Canada and the United States.
