G Force Waste Sorters Founder and CEO Michelle Lee Guiney has been in the waste industry for 15 years.  Michelle began her waste vocation as an Industrial Hygienist conducting clearance testing of containments for hazardous waste abatement projects.

Michelle’s specialty with commercial waste intensified while working for the largest recycler in North America, Waste Management (WM), managing its sustainability program for New England for over a decade.  Becoming acutely aware of how far short we are from responsibly and sustainably managing our waste, she founded G Force Waste Sorters, Inc.

Leadership in Energy and Environmental Design (LEED) accredited by U.S. Green Building Council and both Six Sigma and Zero Waste certified, Michelle also completed UNH Whittemore School for Business and Economics’ Institute for Corporate Sustainability capstone program.  She has been recognized by Environmental Leader along with other national waste news publications and has been involved in various state and national waste and recycling organizations.

Born in traditional Totaunt territory (now Boston), home of the Massachusett Indigenous Nation and descendants of the Neponset Tribe, Michelle, not coincidentally, shares the same birth year as Earth Day, the U.S. Environmental Protection Agency and the passage of two monumental pieces of U.S. environmental legislation, Clean Air Act (amendments) and Resource Recovery Act. Michelle is an avid hiker and frequents Massawachusett (now Blue Hills) outside of her excursions to U.S. and International Parks with her 7 year old Beagle hound-mix E.C.O. (Earth Carbon Off-setter). She is also an aspiring vegan.

Mr. Mitchell began his waste industry career in the late 1980’s working for Boston-based non-profit recycler Earthworm, Inc. Half the time he drove a truck collecting and selling wastepaper. The other part of his work involved selling new services, co-managing administrative functions, and participating in consulting projects.

In the early 1990’s Earthworm was awarded a two-year technical assistance contract with the New York City Department of Sanitation, bringing Adam to the City. Following the completion of the DSNY contract, he was hired to run the recycling division for a New York City private carting company.

Adam returned to Boston in 2000 becoming a minority owner of Save That Stuff, Inc., a leading Resource Management company handling food waste, recyclables, and trash. The capstone of his career in Boston was the development and siting of a 250 ton per day food waste processing facility.

In 2016, after selling his interest in Save That Stuff, Adam returned to New York City joining the 5th largest private hauler, Mr. T Carting. He is responsible for Business Development, manages the Sales Team and serves as an Executive Team Member. Adam led the company’s recycling and food waste collection expansion, resulting in a 2021 diversion rate of 38%.
