About Roger McFadden


About Roger McFadden

Roger McFadden is currently Senior Scientist at McFadden and Associates, LLC. Prior to McFadden and Associates, Roger was Vice President and Senior Scientist at Staples, Inc., with headquarters in Massachusetts a position he held from July 2009 until February 2016. Before joining Staples, Roger was Chief Science Officer for Corporate Express with headquarters in Colorado a position he held from May 2006 until June 2009. Before joining Corporate Express Roger was Senior Scientist and Director of Research and Development for Coastwide Laboratories in Portland Oregon a position he held from 1988 until 2006 when Coastwide Laboratories was acquired by Corporate Express. Before joining Coastwide, Roger worked as a innovative consulting chemist and product designer for several chemical manufacturing companies. 

Holding a MS in chemistry, Roger is a master formulator of cleaning and coatings products for the commercial and household market sectors. He is also a cleaning expert and educator for health care organizations, K-12 schools, higher education institutions, chemical companies, janitorial supply businesses, public agencies and private corporations. He speaks and teaches on a variety of professional cleaning, environmental, safety, health, sustainability and green chemistry topics. Professional cleaning trainers frequently engage Roger to do his creative and fun "Chemistry of Cleaning for Non-Chemists" Classes.

Roger served on the California Green Ribbon Science Panel. He is a charter member of the Green Chemistry Commerce Council (GC3) and is currently on the GC3 Executive Advisory Panel and also serves as a strategic adviser to the GC3 Retail Leadership Council. McFadden served on the Chemical Risk and Information System (CRIS) advisory board for Oregon Health Sciences University (OHSU). Roger served as chairman of Oregon Governor’s Community Sustainability Council Stakeholders Workgroup for Cleaning. Roger currently serves on the Board of Trustees for the John Merck Fund and Board of Directors of two non-profit organizations including Beyond Benign and Clean Production Action.

Roger speaks and teaches on a number of topics including “Greening the Supply Chain to Meet Your Sustainability Objectives”, “Cleaning up the Toxic Supply Chain”, “Building a Supply Chain with an Environmental Conscience”, “Insuring a Future for our Grandkids”, “Supply Chain Management for the Future”, “Small Things Make a Giant Difference”, “Sustainable Cleaning and Improving Indoor Air Quality”, “The Business Case For Transitioning to Safer Chemicals” and many other related topics. Roger has been published in several peer-reviewed publications including New Solutions in addition to numerous trade publications, including Today’s Facility Manager, Commercial Construction and Renovation, Medical Construction and Design Magazine, Cleaning & Maintenance Management Magazine, ISSA Today and is frequently quoted in numerous newspapers, blogs and technical articles and publications. Several of Roger’s articles were published in the Fourth Edition of a University Textbook titled, Professional Management of Housekeeping Operations authored by Dr. Thomas J.A. Jones and published in 2005 by John Wiley & Sons, Inc.

Roger believes that we need a revolution in product design with an environmental conscience and commitment to green chemistry and green engineering; the future belongs to companies that integrate green chemistry and green engineering principles to eliminate hazard and waste at all stages of product life cycle; and that educational institutions can advance the benefits of green chemistry and green engineering by incorporating them in textbooks, curriculum and across multidisciplinary fields including fundamental sciences, business, law and engineering.

Our Focus and Capabilities

Safer Chemicals, Ingredients and Materials


A safer chemical is a chemical, ingredient or material that is more sustainable and has a reduced negative effect on environmental and human health and performs equal to or better than the product that it is designed or intended to replace. 

Our chemical experts can help you identify safer chemical and non-chemical alternatives. Let us help you eliminate and/or avoid the use of chemicals of high concern (CoHC) and prevent regrettable chemical substitutions.

Green Engineering


Green engineering is the design, commercialization, and use of processes and products in a way that reduces pollution, promotes sustainability, and minimizes risk to human health and the environment without sacrificing economic viability and efficiency.

Green engineering embraces the concept that decisions to protect human health and the environment can have the greatest impact and cost-effectiveness when applied early, in the design and development phase of a process or product.

Green engineering processes and products holistically use systems analysis and integrate environmental impact assessment tools. 

Conserve and improve natural ecosystems while protecting human health and well-being. 

Use life-cycle thinking in all engineering activities. 

Ensure that all material and energy inputs and outputs are as inherently safe and benign as possible. 

Minimize depletion of natural resources and strive to prevent waste.

Green Chemistry


Green chemistry is the design of chemical products and processes that reduce or eliminate the generation of hazardous substances. Green chemistry is an innovative, science-based and economic-driven approach to reducing or eliminating the use and generation of substances hazardous to human and environmental health across their lifecycles. It is guided by the twelve principles of green chemistry as presented in the book, “Green Chemistry Theory and Practice” authored by, Dr. Paul T. Anastas and Dr. John C. Warner. The twelve principles of green chemistry include:

1 Prevention - It is better to prevent waste than to treat or clean up waste after it has been created.

2 Atom Economy -- Synthetic methods should be designed to maximize the incorporation of all materials used in the process into the final product.

3 Less Hazardous Chemical Syntheses -- Wherever practicable, synthetic methods should be designed to use and generate substances that possess little or no toxicity to human health and the environment.

4 Designing Safer Chemicals -- Chemical products should be designed to affect their desired function while minimizing their toxicity.

5 Safer Solvents and Auxiliaries -- The use of auxiliary substances (e.g., solvents, separation agents, etc.) should be made unnecessary wherever possible and innocuous when used.

6 Design for Energy Efficiency -- Energy requirements of chemical processes should be recognized for their environmental and economic impacts and should be minimized. If possible, synthetic methods should be conducted at ambient temperature and pressure.

7 Use of Renewable Feedstock -- A raw material or feedstock should be renewable rather than depleting whenever technically and economically practicable.

8 Reduce Derivatives -- Unnecessary derivatization (use of blocking groups, protection, de-protection, temporary modification of physical/chemical processes) should be minimized or avoided if possible, because such steps require additional reagents and can generate waste.

9 Catalysis -- Catalytic reagents (as selective as possible) are superior to stoichiometric reagents.

10 Design for Degradation -- Chemical products should be designed so that at the end of their function they break down into innocuous degradation products and do not persist in the environment.

11 Real-Time Analysis for Pollution Prevention -- Analytical methodologies need to be further developed to allow for real-time, in-process monitoring and control prior to the formation of hazardous substances.

12 Inherently Safer Chemistry for Accident Prevention -- Substances and the form of a substance used in a chemical process should be chosen to minimize the potential for chemical accidents, including releases, explosions, and fires.
