Dear Senator Cardin:
I received my Ph.D. in May 2021 from UMBC’s School of Public Policy at the age of 71. My dissertation focused on municipal solid waste (MSW) in the U.S. I’ve been busy since receiving my degree.
I met with Mayor Brandon Scott and his Department of Public Works leadership team to present my findings and offer my suggestions for Baltimore City. This meeting was facilitated by UMBC’s President Freeman Hrabowski. I joined The Institute for Energy and Resource Management (IeRM) as a Senior Policy Advisor. (https://www.ie-rm.org/). I had an open letter to our national policymakers published on Real Clear Energy in December (https://www.realclearenergy.org/articles/2021/12/09/solid_waste_management_an_open_letter_to_us_senators_and_representatives_807132.html).
I believe that we, as a nation, have an opportunity to change the direction of our policies that determine how we handle our MSW. Currently, we employ a landfill-based infrastructure to dispose of the waste that remains after we compost and recycle. We bury reactive waste in landfills located all over the country. The reactive waste rots and produces methane gas, thus these landfills are a MAJOR source for methane emissions. Recent studies by the EPA and the Environmental Integrity Project (EIP) show the extent of the problem (https://environmentalintegrity.org/reports/greenhouse-gas-emissions-from-marylands-landfills/). The levels of methane emissions have been under-reported for decades. There is a movement towards capturing the methane gas being released from the landfills, but the estimates for successfully capturing the gas are approximately 45-50%.
I believe that we should change paths and implement an integrated solid waste infrastructure based on the international waste management hierarchy by:
1- Avoid producing waste at all levels of production, packaging, and shipping This will take a cooperative effort from all sectors.
2- Reduce the organic waste by composting. Approximately 35% of the waste we produce is organic and can be separated in the home and taken to composting facilities and turned into reusable products. We currently capture 8.5% (EPA). There is much room for improvement.
3- Recycle all available products. We currently recycle 23.6% (EPA). In contrast, some European countries recycling rates are over 50%. Germany recycles 65%, Austria 57%, and Belgium recycles almost 54%. We can do much better if we try.
4- Employ waste-to-energy as the primary method to reduce the volume and recapture the energy released during the combustion process. This heat can be used to generate electricity and a portion of it can be used as a heat source for district heating/ cooling systems in our cities. This method has faced decades of disparagement from many environmental groups. The information distributed by them is outdated. A recent peer-reviewed paper was written by Dr. Marco Castaldi, a professor at CCNY. This paper is a meta- analysis of recent papers that tell the scientific truth about WTE. (https://ccnyeec.org/wp-content/uploads/2021/05/WTE-REPORT7603.pdf). It is the most important paper written about our MSW in recent history. An older paper was written and published by the American Society of Mechanical Engineers (ASME). This paper gives the engineering viewpoint of WTE:

5- We should find the political will to change our landfill-based infrastructure to a WTE-based infrastructure. This will be very hard because of the aforementioned bias and outdated material against WTE. The U.S. is lagging in our use of this method. Many countries around the world have embraced this choice because of the long-term positive environmental benefits.
6- Most of the operating plants are decades old. That doesn’t mean that they have not been upgraded and kept in good operating order. The owners and the allowable emissions are zealously regulated by the EPA and state Departments of the Environment, as they must be. However, many need to have their air pollution control systems upgraded to the latest technology in order to lower emissions further. A good example of how well WTE plants can operate is the West Palm Beach County, FL (WPB) facility. Unit #2 went into service in 2015. Its emissions history proves that we can successfully employ the WTE method. It operates far below the allowable limits set by the EPA. The technology currently exists and is available, but costly. Baltimore’s BRESCO plant owners and Baltimore’s Mayor Young came to an agreement in 2020 to have new air pollution control systems installed on the plant. The cost for this upgrade is reported to be $40 million dollars. I met with the Plant Manager and Plant Engineer last summer and the project is underway in the design phase. The plant’s emissions will mimic the WPB facility’s emissions, except for NOx. The WPB facility was specifically designed for lower NOx emissions.
I applaud congress for passing the 2021 Infrastructure Bill and I’m glad President Biden signed it into law. I propose that you have your staff review Dr. Castaldi’s paper and the ASME paper and forward them to the proper Senate Committees so everyone can see the benefits that we will gain if we use a portion of the funds available in the Infrastructure Bill to help upgrade the existing plants. The citizens who live near the existing WTE plants will benefit from the reduced emissions. Many of the people living near the plants are in the lower socio-economic strata. We will reduce the amount of greenhouse gases we produce.
As I stated in my dissertation- I believe that Waste-to-Energy is the best solution to our dirty Municipal Waste disposal problem until a better method is developed and implemented. Please contact me to continue the conversation.
Very truly yours,
James P. Kruger, III, Ph.D.
