Counterpoint | HERC garbage burner is a metaphorical gnat to pollution’s tiger

Demands to close it are replete with examples of disorganized thinking that fails to account for broader problems and obstacles.

In 1981, Larry, my Minnesota Pollution Control Agency director and a mentor to me, said: “We’re batting at gnats in a jungle filled with tigers.” He taught me how disorganized thinking about environmental dilemmas can mislead.

The gnat getting attention currently is the Hennepin Energy Recovery Center (HERC) and whether that waste-to-energy garbage incinerator in Minneapolis should be closed. If it were, 365,000 tons per year of trash would be shipped and dumped into landfills in Burnsville, Inver Grove Heights, Rosemount, Elk River, Gaylord, Eau Claire, Wis., and Lake Mills, Iowa.

A tiger is the poor air quality and poor health of people in north Minneapolis. The pollution arises mostly from transportation. Great big highways gather cars and trucks; exhaust and dust pollute air. Residents do not have the considerable resources required to mitigate the risks, either through protective HVAC systems or health care. And you can’t close the roads.

When the blame is shifted to racism (environmental justice) and to HERC specifically, then the gnat’s buzzing becomes intense and disturbing. Yet all credible investigations show closing HERC would fail to solve the problem. In fact, closure would increase air pollution. Still, an apparent connection persists in the minds of many. This impairs a real solution.

A second tiger is the increasing generation of unreduced, unrecyclable, non-compostable waste. Waste contains toxic chemicals. We have a take-make-waste product chain. We all use resources this way. Consumers, producers, transporters, wholesalers, importers and retailers make waste. When it becomes more profitable and easier to abandon our take-make-waste resource model, heavily burdened by toxic chemicals, then we’ll all adopt a new and potentially better system. Closing HERC won’t trigger any of those changes.

Yet three people recently held a 12-day hunger strike to demand closure. One of the themes behind that protest is considering HERC (in fact any waste-to-energy facility) as a barrier to “zero waste.” Now the gnat’s buzzing has the ring of a solution. The nexus between “zero waste” and HERC is hazy. Yet, as a scientist and a professor stated in a recent Strib Voices counterpoint they wrote jointly (“Here’s what’s missing in the debate over Hennepin County’s garbage burner,” April 22, responding to the Eric Roper column “Hunger strikers say the government is wrong about incinerator’s risks. I don’t buy it,” April 19), “regional landfills have sufficient capacity through 2054 to serve as a safer bridge while zero-waste infrastructure catches up.”

Their simple conclusion misses some facts:

  1. Lower prices at the dump create an incentive to dispose of even more waste.
    1. You’re just trading one “barrier” (HERC) to “zero waste” for another (a dump).
      1. The dump is not safer than HERC.
        1. Such a shift in products and packaging to “zero waste” is inconceivable even by 2054.
          1. The closure of the Great River Energy waste-to-energy facility in Elk River in 2019 triggered no concomitant progress toward “zero waste.” Instead, all the trash processed there went to the dump. Including the thousands of tons of ferrous and non-ferrous metal removed and recycled from the trash processed by Great River.

            A third tiger is the landfills. The authors of the recent counterpoint say HERC has a PFAS problem and, as mentioned, conclude that dumps are a “safer bridge until 2054.” They remind me of federal Health and Human Services Secretary Robert F. Kennedy Jr. musing about vaccination. HERC has emissions, ergo it is unsafe and must close. RFK Jr. doggedly misses the consequences of being “safer” and unvaccinated — measles, flu, COVID, HPV, death, etc. The counterpoint authors make the same mistake. They missed the consequences of trucking 365,000 tons per year to transfer stations and landfills, then trucking tens of millions of gallons of leachate to publicly owned treatment works (POTWs).

            While they waved their arms at HERC and the shortcomings of testing and risk assessments, they missed that:

            1. A Barr Engineering report showed waste-to-energy (WTE) facilities in Minnesota destroy 99.6% of PFAS in solid waste. Measured WTE stack emissions are 10 to 1,000 times lower than Minnesota Department of Health risk values.
              1. If HERC closes, air quality will get worse due to increased waste transport. Transportation pollution is 60-90% of air emissions, while HERC is about 0.2%.
                1. Landfills are a permanent liability and cost sink that can’t be turned off. They also catch on fire periodically, thereby dwarfing HERC air pollution.
                  1. NASA’s Jet Propulsion Laboratory and the state of California found that landfills are super-emitters of landfill gas containing untreated hazardous air pollutants, methane and PM2.5 (tiny, inhalable particular matter in the atmosphere).
                    1. The U.S. Environmental Protection Agency classifies landfill leachate as the primary risk to PFAS releases to the environment. It flows from landfills and passes largely untreated through POTWs. Then into receiving streams and fish and humans via the Mississippi River and its tributaries.
                      1. Landfills cannot or will not effectively measure air or water emissions. Thus, their full liability is unknown.
                        1. If HERC closes, then Hennepin County waste ratepayers will pay hundreds of millions of dollars in public host fees to Rosemount, Burnsville, Elk River, Gaylord, Dakota County, McLeod County, Inver Grove Heights and Sherburne County, in addition to transport and tipping fees.
                          1. Trash transfer stations will spring up to consolidate garbage, adding to air pollution and odor. Transfer stations catch fire more than landfills.
                            1. The increase in Detroit’s recycling rate (mentioned in the April 22 counterpoint) was not related to closing the waste-to-energy project. The city’s rate went from 4% to almost 8% when the city expanded recycling to multifamily buildings.

                              •••

                              Minnesota needs much more waste-to-energy capacity, not less. That includes expanding HERC. Recycling and composting are stuck at about 50%. Waste generation and landfilling are booming. There appears to be no incentive or requirement to clean up dirty dumps. Landfills weren’t safe in 1979 when the Metropolitan Landfill Abatement Act passed the Legislature, they are not safe now, nor will they likely be in 2054.

                              Further discussion of closing HERC is batting at gnats in a jungle filled with tigers. It distracts from the real problems with health and safety and economics. Disorganized thinking impairs solutions to asthma in Minneapolis, it creates an imagined and unrealistic route to “zero waste,” and it creates flawed analysis misdirecting policymakers to focus on closing a tremendous asset — HERC.
