On June 6, 2022, the U.S. Environmental Protection Agency (EPA) announced the winners of the 2022 Green Chemistry Challenge Awards. EPA states that green chemistry “is the design of chemical products and processes that reduce or eliminate the generation and use of hazardous substances.” According to EPA, the winners “have developed new and innovative green chemistry technologies that provide solutions to significant environmental challenges and spur innovation and economic development.” In support of the Biden Administration’s commitment to tackle the climate crisis, EPA added a new award category recognizing technology that reduces or eliminates greenhouse gas (GHG) emissions. The 2022 winners include:
- Professor Song Lin of Cornell University, Ithaca, New York, for developing a new, more efficient process to create large and complicated molecules that are widely used in the pharmaceutical industry. EPA states that the new technology avoids using hazardous materials and has the potential to reduce both energy use and wasteful byproducts.
- Merck, Rahway, New Jersey, for developing a greener way to make LAGEVRIO™ (molnupiravir), an antiviral treatment for COVID-19. According to EPA, Merck significantly improved the manufacturing process for this antiviral drug in a short time, producing ingredients more efficiently and greatly reducing solvent waste and energy use.
- Amgen, Thousand Oaks, California, for an improved manufacturing process for LUMAKRAS™ (sotorasib), a novel drug for the treatment of certain non-small cell lung cancers. EPA states that Amgen’s innovation decreased manufacturing time, lowered the amount of solvent waste generated, and established a recycling process for a high-value waste stream.
- Provivi, Santa Monica, California, for creating ProviviFAW®, a biological pheromone-based product that controls the fall armyworm, a destructive pest of corn. The product’s pheromone active ingredients are produced through innovative green chemistry using renewable plant oils. According to EPA, ProviviFAW™ can reduce the need for conventional pesticides, which can be harmful to beneficial insects, such as pollinators.
- Professor Mark Mascal of the University of California, Davis, California, in partnership with Origin Materials, for a technology that reduces GHG emissions by producing chemicals for making polyethylene terephthalate (PET) plastic from biomass derived from sugar fructose rather than petroleum. EPA states that this novel chemistry could have significant climate impacts by replacing fossil-based products with carbon-neutral, biobased products, especially when the technology is scaled to an entire industry.
EPA recognized the winners during the American Chemical Society Green Chemistry & Engineering Conference. EPA states that since 1996, EPA and the American Chemical Society, which co-sponsor the awards, have received more than 1,800 nominations and presented awards to 133 technologies that decrease hazardous chemicals and resources, reduce costs, protect public health, and spur economic growth. According to EPA, winning technologies are responsible for reducing the use or generation of nearly one billion pounds of hazardous chemicals, saving over 20 billion gallons of water, and eliminating nearly eight billion pounds of carbon dioxide equivalents released to the air.

The Senate Committee on Environment and Public Works held a hearing on April 6, 2022, on the U.S. Environmental Protection Agency’s (EPA) proposed fiscal year (FY) 2023 budget. The only witness was EPA Administrator Michael S. Regan. In his written testimony, Regan states that EPA has significant responsibilities under amendments to the Toxic Substances Control Act (TSCA) to ensure the safety of chemicals in or entering commerce and addressing unreasonable risks to human health or the environment. President Biden’s proposed budget would provide $124 million and 449 full-time equivalents (FTE) to implement TSCA, an increase of more than $60 million. According to Regan, these resources will support EPA-initiated chemical risk evaluations, issue protective regulations in accordance with statutory timelines, and establish a pipeline of priority chemicals for risk evaluation. EPA “also has significant responsibility under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) to screen new pesticides before they reach the market and ensure pesticides already in commerce are safe.” Regan notes that in addition, EPA is responsible for complying with the Endangered Species Act (ESA) and ensuring that federally endangered and threatened species are not harmed when EPA registers pesticides. The FY 2023 budget includes an additional $4.9 million to enable EPA’s pesticide program to integrate ESA requirements in conducting risk assessments and making risk management decisions that protect federally threatened and endangered species from exposure to new active ingredients.
After Regan gave his opening statement, the Committee asked questions. Committee Chair Tom Carper (D-DE) stated that President Biden requested $124 million and hiring of about 450 FTEs to implement the Frank R. Lautenberg Chemical Safety for the 21st Century Act (Lautenberg Act). According to Carper, despite the previous Administration’s failure to request funds to support implementation of the Lautenberg Act, EPA professionals have worked hard to meet the aspirations and mandates of the Act. Carper asked Regan to describe the resource challenges that the TSCA program is currently facing and how EPA plans to fulfill its obligations under the Lautenberg Act if Congress appropriates the increase in resources requested by the Biden Administration. Regan stated that the previous Administration missed nine of ten deadlines for chemical risk review evaluations. Meanwhile, the workload for the Biden EPA has doubled, with 20 high-priority risk evaluations to do and ten risk management rules to write, but EPA is still working with the same budget that it had before the Lautenberg Act. As a result, EPA has only about 50 percent of the resources that it thinks it needs to review the safety of new chemicals quickly and in the way that the law requires. The proposed FY 2023 budget reflects what EPA thinks it will actually take to implement the Lautenberg Act in the way that Congress and stakeholders expect and deserve. According to Regan, EPA would put those resources to good use. EPA wants to keep pace with what Congress requested.
According to Senator Kevin Cramer (R-ND), the North Dakota Agricultural Commissioner sent a letter to EPA’s Office of Pesticide Programs (OPP) (still waiting for a response) about unused stocks of chlorpyrifos. In August 2021, EPA issued a final rule revoking all tolerances for chlorpyrifos. Cramer stated that under the final rule, farmers and retailers have six months to dispose of it. To date, there has been very little to no guidance on how to dispose of it, and without guidance from EPA, there is worry about improper disposal or illegal use. Cramer asked Regan if he could provide some assurance that EPA is not going to seek to punish growers that currently have product in their possession. Regan responded that in this case, like others, EPA found itself in a situation where, because of inaction over decades, the court put it on a timeline to take action. Regan stated that he can commit that the EPA regional office is working with North Dakota now to think about how to address the situation.
As Regan noted in his testimony before the Committee, the Lautenberg Act includes statutory deadlines that EPA must meet as it evaluates existing chemicals. In addition to these mandates, after reviewing the risk evaluations completed by the previous Administration, the Biden EPA announced June 30, 2021, its plans to review and address certain issues. The Biden EPA is working to complete its revisions to the final risk evaluations and move to the risk management rulemaking stage. Under the previous Administration, EPA, in 2020 and 2021, directed significant energy to developing risk evaluations for the “Next 20” chemicals designated as high priority for risk evaluations through the TSCA prioritization process, completing scoping documents in September 2020. In light of the Biden Administration’s revised approach to risk evaluations, however, those scoping documents will need to be revisited and revised as appropriate, and work is expected to continue through 2022 and probably much of 2023. EPA also now has received four manufacturer-requested risk evaluations, three of which have been granted as of mid-December 2021, and one of which is pending. Without significant resources, the Biden EPA will struggle to meet the ambitious goals of the Lautenberg Act.

On February 24, 2022, EPA announced the selection of 11 organizations to receive a total of approximately $2 million in funding to divert food waste from landfills by expanding anaerobic digester capacity nationwide. Anaerobic digestion (AD) produces biogas that can be captured and used for energy production and digestate (a fertilizer product) by using microorganisms to break down organic materials, such as food scraps and manure, in the absence of oxygen. By reducing the amount of wasted food in landfills and consequently methane emissions, AD may reduce significantly the impacts of climate change. EPA’s food recovery hierarchy includes AD as a strategy that is preferable to landfilling and incineration, because it contributes to building a circular economy. Each of the selected organizations will receive between $150,000 and $200,000 over two years. A list of the selected projects is available here.

On January 10, 2022, the Massachusetts Institute of Technology (MIT) announced that a team of its researchers has developed a promising approach to control methane emissions and remove methane from the air using zeolite clay. Zeolite clay is inexpensive and abundant. The MIT team found that, when treated with copper, the material is very effective at absorbing methane from the air even at low concentrations. According to researcher and Associate Professor of Civil and Environmental Engineering, Desiree Plata, Ph.D., this process is advantageous over other approaches to removing methane from the air, as other methods tend to use more expensive catalysts that require high temperatures. The method converts methane into carbon dioxide that, according to Plata, is much less impactful in the atmosphere than methane. Methane is about 80 times stronger as a greenhouse gas (GHG) over the first 20 years, and approximately 25 times stronger for the first century.
MIT researchers still have outstanding engineering details to address in this process. To do so, the U.S. Department of Energy (DOE) awarded a $2 million grant for MIT to continue to develop specific equipment for methane removal in places with concentrated sources of methane, such as dairy barns and coal mines. Plata reported that the next phase of the project will focus largely on ways to structure the clay material in a multiscale, hierarchical configuration to demonstrate a proof of concept that this method can work in the field.

On May 4, 2021, the U.S. Department of Energy’s (DOE) Argonne National Laboratory published an article titled “Retrospective Analysis of the U.S. Corn Ethanol Industry for 2005-2019: Implications for Greenhouse Gas Emission Reductions.” Using a life-cycle analysis (LCA), researchers at the Argonne National Laboratory quantified the life cycle of greenhouse gas (GHG) emissions of fuels to compare relative GHG impacts among different fuel production pathways. According to the retrospective analysis conducted, since 2000, corn ethanol production in the United States quadrupled due to supportive biofuels policies such as the U.S. Environmental Protection Agency’s (EPA) Renewable Fuel Standard (RFS). Consequently, carbon intensity (CI) over the past 15 years has significantly decreased by 23 percent. Since 2000, the corn ethanol production pathway, including corn farming and biorefineries, has substantially evolved. Researchers state in the article that this shift into more efficient farming and biorefinery practices increases revenue while also potentially reducing the emission burdens of ethanol production. DOE’s Argonne National Laboratory researchers conclude that biofuels, including corn ethanol, can and likely will play a key role in decarbonizing the U.S. economy.
The article’s findings will also be used by DOE to update key corn ethanol parameters in the Argonne National Laboratory’s Greenhouse Gases, Regulated Emissions, and Energy Use in Technologies (GREET) Model 2021, which will be released in October 2021.
