Greener Product Design Examples
Published in Al Iannuzzi, Greener Products, 2017
Proctor & Gamble evaluated the full life cycle of using a mop and bucket for cleaning and realized that consumers waste massive amounts of water by cleaning their houses with a traditional mop and bucket. This enabled product developers to focus their efforts on the most important area and generated a significant sustainability innovation. The Swiffer Wet Pad is a more-convenient way to clean that allows the consumer to combine a mop, bucket, and cleaning solution. A household that uses this product will save more than 70 gallons of water every year in comparison to a mop and bucket—more convenient and lower environmental impact.
Workstation Design

Figure 11.20 shows how this same principle applies to hand-polishing operations, whether they are with a rag (in a factory or on your car) or performed with pressure applied by the end of a pole or hose (broom, mop, vacuum cleaner). Writing vs. printing is another example. In a kitchen, stirring soup represents the same principle. (If there is insufficient mixing of product with circular stirring in a circular container, use a rectangular container to furnish the turbulence rather than using a zigzag motion.) Bicycle pedals are another example of the principle of circular motion.
Disinfecting Agents

Within the healthcare setting and most commonly reported in the hospital setting, test reports have shown the effect that cleaning the surface has on the microbial levels in controlled areas. Many publications purport this concept. In the pharmaceutical and biotechnology setting, a test report conducted and published in 1989 by A. Vellutato, Sr. and A. Vellutato, Jr. of Veltek Associates, Inc. demonstrated the effect cleaning the surfaces has on the level of microbial contamination found on the surface. The study focused on the concept that cleaning alone would remove most of the existing microbial contamination. In the report, all surfaces were cleaned with a sodium lauryl sulfate detergent and mechanical cleaning action on a daily basis. Such cleaning was conducted in a Grade A/B, Grade A, ISO 5 area. Environmental monitoring was routinely conducted at air, surface, and personnel sampling locations. The manufacturing operations filled an average of 4,000 units of 500 ml bags of USP water-for-injection. Manufacturing operations ran for four hours per day and upon completion of manufacturing, the clean room was completely cleaned. The cleaning mechanism utilized a mop and two-bucket system, a sprayer, and a squeegee. The procedure for cleaning was to apply the sodium lauryl sulfate detergent (DECON-Clean®) to the surface utilizing a top to bottom approach. Upon completion of the mopping, the chemical was then sprayed on to the surface and all excess liquid on the surfaces pulled downward by squeegee to the floor. The remaining liquid was then collected on the floor and removed. The results for 30 days met industry limits for Grade A/B, Grade A, ISO 5. At 45 days, control was lost, results exceeded limits and a sporicidal agent was used once on day 45. The limits returned to acceptable levels for 31 days (day 76 of the study). The final conclusion was one to two uses of a sporicidal agent with the cleaning regime controlled the environment.

An aluminum telescopic mop handle and a 60 cm width mop frame were used in this study. The mop handle extended from 1.0 m to 1.7 m and the shaft of the mop handle was 2.6 cm in diameter. The handle grip was 13.5 cm in length and 3.2 cm in diameter. A microfiber mop cloth was used, and a standard moisture content was achieved by moisturizing the mop with 60 ml of water.
