The U.S. Department of Energy’s (DOE) Bioenergy Technologies Office (BETO) announced on August 11, 2022, that a research team from Pacific Northwest National Laboratory investigated how potassium in biomass feedstocks poisons a catalyst. The researchers focused their study on potassium, a common alkali metal found in biomass feedstocks, since previous analysis of deactivated catalysts after catalytic fast pyrolysis (CFP) of woody biomass feedstock revealed potassium accumulation on the catalysts’ surface.
 
The research team simulated catalyst poisoning at different potassium levels to trigger deactivation during industrial operations. They then analyzed the catalysts and conducted kinetic measurements to determine how the catalysts’ ability to catalyze chemical reaction changed with the introduction of potassium. According to BETO, the team found potassium poisoning could be substantially mitigated with a developed regeneration method -- a water washing process -- that can successfully remove most of the loaded potassium, restoring more than 90 percent of the catalytic activities.
 
BETO states that the results of these studies provide new insights for the bioenergy industry that will foster improved catalyst design and regeneration for longer lasting catalysts. The studies also created “a solid knowledge base for developers of biomass conversion technologies to continue to build upon, making new and innovative conversion technologies less risky to research and develop.” According to BETO, the work “also supports accelerated process development that can help industry convert biomass feedstocks commercially, leading to more effective and inexpensive production of biofuels.”

The U.S. Environmental Protection Agency will hold a virtual public meeting April 20-21, 2022, to seek individual input on the proposed Toxic Substances Control Act (TSCA) New Chemicals Collaborative Research Program. 87 Fed. Reg. 10784. In addition, EPA announced the availability of and is soliciting public comment on the draft document entitled “Modernizing the Process and Bringing Innovative Science to Evaluate New Chemicals Under TSCA.” EPA states that the Office of Chemical Safety and Pollution Prevention (OCSPP) is proposing to develop and implement a multi-year collaborative research program focused on approaches for performing risk assessments on new chemical substances under TSCA. According to EPA, the effort will be performed in partnership with its Office of Research and Development (ORD) and other federal entities to leverage their expertise and resources. Written comments are due April 26, 2022. Registration for the meeting is now open.

According to EPA, the research program will refine existing approaches and develop and implement new approach methodologies (NAM) to ensure the best available science is used in TSCA new chemical evaluations. Key areas proposed in the TSCA New Chemicals Collaborative Research Program include:

  • Updating OCSPP’s approach to using data from structurally similar chemicals to determine potential risks from new chemicals, also known as read-across. According to EPA, this will increase the efficiency of new chemical reviews, promoting the use of the best available data to protect human health and the environment.
  • Digitizing and consolidating information on chemicals to include data and studies that currently exist only in hard copy or in various disparate TSCA databases. EPA will combine the information with publicly available sources to expand the amount of information available, enhancing chemical reviews and enabling efficient sharing of chemical information across EPA. Safeguards for confidential business information (CBI) will be maintained as appropriate in this process.
  • Updating and augmenting the models used for predicting a chemical’s physical-chemical properties and environmental fate/transport, hazard, exposure, and toxicokinetics to provide a suite of models to be used for new chemicals assessments. The goal of this effort is to update the models to reflect the best available science, increase transparency, and establish a process for updating these models as science evolves.
  • Exploring ways to integrate and apply NAMs in new chemicals assessments, reducing the use of animal testing. EPA states that as this effort evolves, the goal is to develop a suite of accepted, fit-for-purpose NAMs that could be used by external stakeholders for data submissions under TSCA, as well as informing and expanding new chemical categories.
  • Developing a decision support tool that integrates the various information streams specifically used for new chemical risk assessments. The decision support tool will integrate more efficiently all the data streams (e.g., chemistry, fate, exposures, hazards) into a final risk assessment and transparently document the decisions and assumptions made. Simply put, this will facilitate the new chemicals program tracking decisions over time and evaluating consistency within and across chemistries.

EPA states that additional information on each of these areas will be provided in the draft collaborative research plan that will be available in the docket by March 14, 2022. Later in 2022, EPA plans to engage its Board of Scientific Counselors (BOSC), a federal advisory committee, for peer review. EPA also intends to issue a Federal Register notice announcing the BOSC meeting and to open a docket for public comments.

Although the notice states that EPA’s background documents and the related supporting materials to the draft are available in the docket established for this meeting, Docket ID Number EPA-HQ-OPPT-2022-0218, nothing is available at this time. EPA states that it will provide additional background documents as the materials become available. After the virtual public meeting, EPA will prepare meeting minutes summarizing the individual comments received at the meeting. EPA will post the meeting minutes on its website and in the relevant docket.

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.
