Waste Prevention and Management

In our last blog we discussed one of the principles of green chemistry – designing safer chemicals. This time we’ll talk about another principle that AEC Systems considers paramount every time we design a parts washer for a client: prevention.

Zero Waste2It is better to prevent waste than to treat or clean up waste after it has been created.

In the natural world, organic matter  decays and becomes part of its environment when it dies, nourishing the soil and providing nutrients for future life. Ideally, we could design cleaning systems that accomplished the same: recycling everything for another use and producing zero waste.

Zero waste management is an important goal companies strive for a number of reasons. First, environmental awareness is more prevalent everywhere as the limitations of our planet become more obvious. Anything that can be reused costs less money and requires the mining or production of fewer resources. Second, the government is becoming more strict in its regulation of waste as a way of stopping the kinds of environmental disasters of the twentieth century from occurring, and no company wants to deal with either lawsuits or cleanup of that kind of damage. Finally, disposal of true waste – material that cannot be reused in any way and/or is toxic – is becoming much more expensive. Striving towards zero waste in cleaning processes makes sense in all of these ways.

Roger Sheldon,  Professor Emeritus of Biocatalysis and Organic Chemistry at Delft University of Technology in the Netherlands, described the measure of waste as the E-factor: the mass ratio of waste to desire product and the atom efficiency. This idea and terminology is now used by companies globally for assessing the efficiency and environmental impact of chemical processes.

When we interviewed Ray Graffia of Arbortech Corporation, he discussed the usefulness of the washer washer. Utilizing a filtration system, companies can reuse the same wash water over and over, saving money and limiting waste. But what about producing less waste in the first place? Can a system be designed that will produce no waste byproducts, heat, or exhaust?

That is the question that engineers worldwide seek to answer in the affirmative. Recycling or reusing oil, grease, dirt, swarf, and other residues that are removed from parts during the cleaning process might seem an impossible goal. However, we’ve seen other unimaginable goals achieved over and over in the last fifty years, including putting men on the moon and designing complex computing systems that can be carried around in anyone’s back pocket. With time, effort, research, and dedication very little is impossible.

AEC Systems has a commitment to building the best, most efficient, and most environmentally friendly parts washing systems for our customers, and a core component of that is pursuing zero waste as a goal.
