Environmental benefits of source reduction


Small Targeted Changes Delivering Significant Results

Improving The Heartbeat Of Industry   

There are over 4 billion square feet of commercial office space in America.  Over 9 million people find employment in commercial offices across America, we will be taking a closer look at how an USAF base has benefited from our ASTEW Matrix.

Background Information

USAF Base Arizona.
Facility type: ~Multi use complex 166 buildings included in use reduction protocol.
Fifty-six-Hundred active staff members are part of the source reduction system.
Facilities participating in system includes daycare centers, gyms, research facilities, base administration, base support services, et cetera.



Reduce environmental footprint without capital expenditure
Improve product quality
Reduce purchase expenditure

Let’s take a closer look:

“Sustainable Design is a design philosophy that seeks to maximize the quality of the community and the built environment and services while minimizing or eliminating the negative impact on the natural environment.”

Sustainability initiatives include conscious efforts to produce zero waste, improve air quality, including Indoor Air Quality (IAQ), and maintain the health and wellbeing of the workforce and extended community.

ASTEW was proposed as a sustainability initiative to achieve stated objectives.
The focus was concentrated on source reduction from the most overlooked places: Restroom care products as well as the improvement of staff wellbeing by improving the sanitation levels of their microenvironments.

The facility’s multiple complexes were assessed a review of the custodial services, cleaning chemicals, restroom care products including quality and type, custodial labor allocation, as well as, procedures were analyzed.
ASTEW measures where enacted: Contractor training and in-service protocols were initiated. Cleaning chemicals were analyzed, and known allergen sources were removed and replaced with ecologically safer alternatives, cleaning procedures and equipment were adjusted to accommodate the changes.

Restroom care products were standardized and consolidated, reducing stocking time. Quality of the restroom care products was improved, significantly reducing in-use waste as well as the frequency needed for restocking. Controlled nonbattery touchless dispensers were installed, decreasing the risk of cross-contamination. The controlled dispensing system also ensured that all product was used before restocking dispensers diminishing unused product waste.

With the diminished labor demand required for on restocking, the contractor was able to increase the time spent performing cleaning procedures, improving overall sanitation levels, as well as, definitively impoving the quality of the service.




Overlooked places: Source reduction produces a cascade of expected and sometimes unconsidered benefits. When reducing the need for one ton of paper, the effect includes the saving of 17 trees, each tree scrubs 48 pounds of CO2 per year. Forever ton of paper not produced you safe over 700 gallons of oil and 7,000 gallons of water. One ton of restroom care products is approximately 71 cases of product, requiring over 8 hours of labor to stock the restrooms. Redirecting that time to sanitation procedures will improve the health of our microenvironment and subsequently reduce your risk of infection.

As Vincent Van Gogh said “Great things are created by a series of small things brought together”.

Overlooked Places

Source reduction is a critical component of protecting the future we borrowed. Evaluating product selections based on performance as opposed to price will provide a significant benefit.

Client Actuated Custom Solution

We work with our clients to discover what solutions work best for them. We achieve our clients’ objectives by focusing on the interconnection the solutions provide towards their long-term goals. Workplace culture building, employee engagement, productivity escalation, employee wellbeing, in addition to community responsibility, along with encouraging community extolment for our client’s business, all influence how proposed solutions are efficaciously optimized.

Non-Hazardous Solid Waste

Small changes in product selection resulted in 67 tons of organic waste from entering the landfill, preventing 67 tons of methane, the CO2 equivalent of removing 1,206 from the road per year.

The Results

With the diminished labor demand required for restocking, the contractor was able to increase the time spent performing sanitation procedures, enhancing overall cleanliness levels of the microenvironment, as well as, definitively improving the quality of the service.

We are intrinsically tethered to our micro and macro environments.Through education, training, tool placement, and monitoring, we capitalize on that connection improving overall wellbeing.
