Several years ago, this would have been quite difficult. However, recent studies have been released that indicate green cleaning, along with the implementation of more-effective cleaning techniques and systems, does indeed pay off.
Case in Point #1: Worker Productivity
One of the benefits of environmentally preferable cleaning products is they have less negative impact on indoor air quality. One reason for this is they release fewer airborne volatile organic compounds (VOCs), which have been proven to contribute to a variety of respiratory and other health-related problems.
Researcher and consultant Dr. Judith Heerwagen studied the effects of improved indoor air quality on worker productivity. Evaluating numerous well-documented studies, Heerwagen found that productivity increases ranging from 0.5 percent to 7.0 percent, which translates into approximately 3 to 34 minutes saved per day, are not unusual when the indoor environment is improved, often as a result of using environmentally preferable cleaning products.¹
This improved productivity may happen because workers are not interrupted as often to sneeze, cough, or blow their nose, as a result of fewer airborne VOCs from conventional cleaning products. Or it can be because a worker simply feels better and more productive in an atmosphere free of respiratory irritants.
Increased productivity also means money on the table for business owners. According to the Building Owners and Managers Association (BOMA), salaries and benefits paid to workers in a “Class A” office building total approximately $300 per square foot.² This means that an increase in worker productivity of just 0.5 percent translates into $1.50 per square foot. Multiply this times hundreds if not thousands of workers, and you can see how the savings mount up and do so quickly.
Case in Point #2: Healthier Cleaning Professionals
Often when we discuss the benefits of green cleaning products, our focus is on how they help protect the environment. However, the emphasis should first be on how they help protect the health of cleaning professionals, the people who spend hours every day spraying and wiping chemicals on surfaces and performing a variety of cleaning tasks. And protecting their health is another place we see the financial benefits of using green cleaning products.
The U.S. Department of Labor ranks the use of some cleaning chemicals among the top hazards in the professional cleaning industry. In 2005 there were nearly 220,000 accidental poisonings, including 36 deaths, as a result of using or misusing cleaning chemicals, according to the American Association of Poison Control Centers. Additionally, exposure to some conventional cleaning products introduces concerns about the chronic, long-term effects on workers, which the association indicates are hard to measure or report.
It is believed that the average amount of time lost when a custodial worker suffers a job-related injury as a result of using a conventional cleaning chemical is about 18 hours. Each incident can cost an employer an average of $650 or more in medical and related costs. On top of this, there may be added costs associated with productivity loss and potential litigation costs. By conservative estimates in the food industry alone, avoiding these costs could save employers more than $15 million annually. Similar if not much larger savings are possible in the education, hospitality, and healthcare sectors, which employ thousands of custodial workers.
Ever hear of the expression, “Penny wise but pound foolish”? Usually, it refers to choosing one product over another because it costs less only to find that, in the end, it costs more to use – perhaps because more of the product must be used or it simply does not work as well – than the more expensive product. Ultimately, the buyer would have saved a tidy sum if he or she had just purchased the more expensive item in the first place.
Although most environmentally preferable cleaning products are now comparable in price to their conventional counterparts, some may still cost a bit more. So to save money on the “sticker” price, some industries readily use powerful cleaning chemicals that must be disposed of according to regulations established by the U.S. Environmental Protection Agency (EPA). However, disposing of these chemicals can be costly. In fact, disposal can actually cost more than purchasing the product in the first place, an expense that could be eliminated by selecting a more environmentally responsible cleaning product from the start.³
The Role of More-Effective Cleaning
These examples and others show us that the use of environmentally preferable cleaning products can offer a significant cost savings, especially when it comes to improving worker productivity and protecting health. However, saving money can best be accomplished when the most-effective cleaning systems and techniques are employed.
At the Cleaning Industry Research Institute symposium held earlier this year, the importance of more-effective cleaning in eliminating surface-area germs and bacteria that can harm human health was addressed. Studies presented indicate that many traditional cleaning methods, such as the conventional cleaning of floors with string and even microfiber mops, are not that effective in eliminating potentially harmful contaminants when compared to newer technologies such as spray-and-vac cleaning systems.
Cleaning systems and environmentally preferable cleaning products are working together to help protect the health of the indoor environment as never before. These benefits are tangible-they do show us the money.
Selecting Safer Environmentally Preferable Cleaning Products
At one time, it was difficult for facility managers and BSCs to select green cleaning products because there were no formal, universally accepted, consensus-based green cleaning standards. In fact, some manufacturers simply self-declared their products green, often using the best studies and information of the day; others sought to take advantage of green marketing opportunities with little or no proof that their products were actually helpful to the environment. The result: confusion among end users, manufacturers, and governments-which also stymied the adoption of green cleaning.
Today, much of this confusion has been eliminated because of groups such as GreenSeal and EcoLogo. Certification by these third-party organizations means, among other things, that the products and their ingredients:
- Have been analyzed and verified by independent, accredited laboratories
- Have a reduced impact on the environment
- Are rapidly biodegradable and nontoxic
- Meet specific ISO (International Organization for Standardization) guidelines
- Are not known to be human health hazards
