A Day of Insight on Major Environmental Topics — and Proper Garbage Disposer Use

The sharing of thoughtful expertise on matters of great long-term importance – that was the virtue and strength of a conference at Marquette Law School on May 16. “Innovation at the Food-Energy-Water Nexus” brought together about 75 professionals and academic figures from across Wisconsin and the country who work in these tightly related fields. 

The day-long session, organized by David Strifling, director of the Water Law and Policy Initiative at Marquette Law School, and an organizing committee, had a broad theme of how leaders and researchers in these crucial fields could work together and stretch their vision to serve the best and broadest sense of the public good.

Speakers at the event covered a variety of topics including energy recovery at wastewater treatment facilities, the importance of groundwater, ethical aspects of decisions about natural resources, and the deep links between agriculture, water, and energy. Yet for the handful of people in the audience who were less technical in their backgrounds — and for a larger audience such as this one – the most practical piece of wisdom may well have been a bit of advice on how to use a garbage disposal.

In the question and answer session at the end of a panel discussion on environmental issues, one of those non-technical people in the audience (no, it wasn’t me, but I had the same question on my mind) asked if it was better for the environment to put your food waste into your garbage disposer, sending it to a wastewater treatment facility, or into your garbage, sending it to a landfill. She said her garbage disposer sometimes got clogged, causing flooding in her basement, so she stopped using it.

One of the panelists was Michael Keleman, manager of environmental engineering for InSinkErator, a leader in the garbage disposal field. The company is headquartered in Sturdevant, in Racine County. Not surprisingly, Keleman is partial to garbage disposer units and putting most food waste down the sink.

He told the questioner, “It seems like people, when they have problems, it’s probably from improper use. That’s this: They’ll load up the chamber or the sink and say, ‘Oop, it’s time to use the disposer, my sink’s getting full, it’s running over the top.’ They’ll turn the disposer on and then they’ll turn the water on and then, as soon as they see the food and water disappear, they’ll turn the water off and the disposer off.

“What you really want to do is turn your water on first, then turn your disposer on second, and then add your food waste gradually. Let it grind until you don’t hear any food waste any more. Turn the disposer off and let the water run for a few seconds.”

So is it better to do that than throw your waste in the garbage can? Keleman said food waste is 70 to 90 percent  water. “Why are we handling this as a solid waste?” he asked. “It’s not really solid any more if you’re using the disposer right.” Its density is about the same as water and it will be successfully transported to a treatment facility that can recover resources – including clean water and energy – from it, and simultaneously avoid land use problems.

Keleman had less cheerful advice on a second matter raised by the questioner, avoiding disposing of unneeded drugs by flushing them down the toilet or sink.

While saying programs to dispose of pharmaceuticals by other means are “great,” Keleman was skeptical of how much difference they make.

“We take in these pharmaceuticals, we excrete back over 90% of it,” he said. “The bottom line is, as long as pharmacy is the way it is, we’re going to excrete most of these endocrine disrupters and birth control pills, even caffeine, all the things – the pain killers, benzodiazepines. These are all things our society is taking and we’re excreting. So no matter how good a job we do at take-back programs, they’re still going to be this in the waste water stream.“

In Keleman’s accounting, score one for proper use of a garbage disposer. And do what you can about disposing of drugs – but don’t have illusions about I in a society where drug use is so extensive.

What President Trump’s “Budget Blueprint” Could Mean For The Great Lakes

At a recent Law School event, several panelists (including me) discussed the potential for the Trump administration to make important changes to the law in our respective areas of concentration. I said at the time that environmental law has proven quite resistant to previous efforts that would have weakened or erased it. Part of this resiliency is due A photo of a wetlandto the lengthy time horizon typically involved in repealing and replacing statutes and rules; another major factor is longstanding public opposition to such changes. With that said, major attempts are underway that, if implemented, would seriously undermine bulwarks of environmental law such as the Endangered Species Act, the National Environmental Policy Act, and the Antiquities Act. The Trump EPA has also recently begun the long process of repealing and replacing the Clean Water Rule, under direction from President Trump to rewrite it in a manner consistent with one of Justice Scalia’s previous opinions.

Whether or not those efforts succeed, the executive branch has a major impact on the day-to-day operation of environmental law even in the absence of major statutory or regulatory reforms. The most direct avenues for this are through budgeting decisions and enforcement discretion. With debates over spending engulfing Washington, it’s worth examining the potential impact of President Trump’s recent “America First – Budget Blueprint” on the Great Lakes region. Several features of the proposal have generated controversy and may be especially significant in the Great Lakes region:

Innovation at the Food-Energy-Water Nexus

I have previously written in this space about the importance of policy innovation at the food-energy-water nexus. On Tuesday, May 16, Marquette Law School will host an interactive and interdisciplinary workshop to explore those issues, drawing from engineering, legal, scientific, and policy spheres. The workshop format and accompanying discussions will (1) provoke conversations about overcoming barriers to the implementation of innovative water solutions, (2) A circle graph showing how water and energy are relatedstimulate ideas for focused academic research in the nexus, and (3) drive the development of organizational policy and technology roadmaps. The event incorporates sessions on energy use, recovery, and minimization at water and wastewater utilities; on groundwater; on agricultural sustainability and food waste; and on ethical considerations for stakeholders, a topic often absent from similar events. A working lunch and roundtable discussion as well as breakout sessions will invite and encourage broad-based attendee participation. Attendees will also have numerous opportunities to network with experts, researchers, and students. This event is sponsored by a grant from the National Science Foundation I/UCRC for Water Equipment and Policy. More details, including an agenda and registration information, are available here. Confirmed participants include:
