The U.S. Department of Energy’s (DOE) Bioenergy Technologies Office (BETO) announced on May 30, 2023, that the Chemical Catalysis for Bioenergy Consortium (ChemCatBio) will hold a webinar on June 14, 2023, on “Perspectives on Engineered Catalyst Design and Forming.” ChemCatBio is a consortium of eight DOE national laboratories overseen by BETO. According to BETO, the performance evaluation, and ultimate commercial adoption, of next-generation catalyst materials requires the development of strategies to prepare complex engineered catalysts suitable for operation in commercially relevant reactor configurations and scales. To leverage the fundamental advancements ChemCatBio has made in catalyst technology, BETO states that the consortium recently implemented a new vision to address risks by focusing on process integration and fuel production with engineered catalysts.
 
In the webinar, Bruce Adkins (Oak Ridge National Laboratory), Frederick Baddour (National Renewable Energy Laboratory), and Matthew Greaney (Clariant) will present critical considerations for the “engineered” catalyst; an industrial perspective on catalyst design and forming; and ChemCatBio’s industry-informed capabilities that support the transition to more commercially relevant catalyst forms. The webinar will end with a question and answer session.

The U.S. Department of Energy’s (DOE) Bioenergy Technologies Office (BETO) has launched a new, comprehensive web page dedicated to one of its priority subprograms, Renewable Carbon Resources (RCR), which helps develop RCR technologies and creates strategies for bioenergy and bioproducts production. In its May 19, 2023, announcement, BETO states that RCR supports applied research and pilot-scale projects for the production, harvesting/collection, supply logistics, storage, and preprocessing of biomass and wastes to feedstock. According to BETO, RCRs are carbon-based resources generated through photosynthesis (plants and algae) or through waste generation (non-recycled portions of municipal solid waste, biosolids, sludges, plastics, and carbon dioxide and industrial waste gases). The subprogram aims to optimize responsibly the use of each of these resources using sustainability indicators such as land-use changes, greenhouse gas emissions, biodiversity, resource conservation, wildlife habitat, fire mitigation, food security, social well-being, and water, soil, and air quality.
 
The newly launched RCR web page is organized around the following activities:

• Production and sourcing;
• Logistics;
• Feedstock-conversion interface;
• Waste management technologies;
• Environmental remediation; and
• Carbon management.

The U.S. Department of Energy’s (DOE) Bioenergy Technologies Office (BETO) announced on May 15, 2023, that a new workflow developed by researchers at the Agile BioFoundry (ABF), a BETO-funded consortium of national laboratories and Agilent Research Laboratories (Agilent) addresses the need for faster analytical tools. According to BETO, the workflow “combines state-of-the-art analytical technologies with a machine learning-based algorithm, providing a faster and more powerful way to process data that could accelerate the Design-Build-Test-Learn framework, a bio-engineering cycle used to improve biomanufacturing research and processes.”
 
BETO notes that speeding up the bio-engineering cycle could ultimately speed up biomanufacturing research. According to BETO, one of the biggest barriers to accomplishing this is the ability to improve the Learn step of the cycle, which involves using data to improve future cycles. Improvements to the Learn step can happen only if large amounts of high-quality data are gathered in the Test step of the cycle, however.
 
BETO states that the consortium teams set out to create a workflow that could generate high-quality analytical Test data that could feed into the Learn step. The workflow they developed includes several components:

• A high-throughput analytical method developed in collaboration with Agilent that enables a threefold reduction in sample analysis time (compared to previous conventional approaches) by using optimized liquid chromatography conditions;
• The Automated Method Selection Software tool, which predicts the best liquid chromatography method to use for analyzing new molecules of interest; and
• PeakDecoder, a novel algorithm that processes multi-dimensional metabolite data and automatically calculates errors in metabolite identification.

To test the workflow’s effectiveness, the researchers used it to study metabolites of various strains of microorganisms engineered by ABF. The microorganisms they tested all have the capacity to make various bioproducts, such as polymer and diesel fuel precursors. According to BETO, using their workflow, the researchers were able to interpret 2,683 metabolite features across 116 microbial samples.
 
BETO states that the researchers see PeakDecoder “as a stepping stone towards creating an automated data-gathering pipeline.” According to BETO, the team is already working on leveraging state-of-the-art artificial intelligence methods like computer vision used in other fields. The next version of PeakDecoder is expected to have improved automation and identification performance and to be more applicable to other types of molecular profiling, including proteomics workflows.

On March 23, 2023, the U.S. Department of Energy’s (DOE) Bioenergy Technologies Office (BETO) announced the release of its 2023 Multi-Year Program Plan (MYPP). The MYPP is used as an operational guide, setting forth BETO’s mission, goals, and strategic approach. It also serves as a resource to help manage and coordinate BETO’s activities and communicate its strategy to stakeholders and the public. The new plan identifies BETO’s forthcoming research, development, and demonstration (RD&D) plans and activities and outlines why these undertakings are critical to meeting the energy and sustainability challenges facing our nation. According to BETO, due to the urgency of reducing greenhouse gases (GHG) across all modes of transportation, BETO has shifted its focus to low-carbon and net-zero carbon fuels for the aviation, marine, rail, and heavy-duty, long-haul industries, which have fewer options for reducing carbon impact. The MYPP prioritizes strategies to enable the decarbonization of the industrial sector via the advancement of renewable chemicals and materials, recognizing the potential for bioenergy technologies to decarbonize communities and other economic sectors through sustainable agriculture, improved waste management, and additional beneficial uses of biomass.

The U.S. Department of Energy’s Bioenergy Technologies Office (BETO) announced on January 23, 2023, that researchers at the National Renewable Energy Laboratory (NREL) examined the benefits and trade-offs of current and emerging technologies for recycling certain types of plastics to determine the optimal options. According to BETO, the researchers provided a comparison of various closed-loop recycling technologies, which allow for the reuse of plastic through mechanical and chemical reprocessing, eliminating the need for fossil-fuel-derived virgin materials. They considered technical metrics, such as the quality and retention of recycled plastics, as well as environmental metrics, including energy use and greenhouse gas (GHG) emissions. BETO and the Advanced Materials and Manufacturing Technologies Office provided funding for the research as part of the BOTTLE™ Consortium (Bio-Optimized Technologies to keep Thermoplastics out of Landfills and the Environment). The Consortium is a collaborative effort among industry, academia, national labs, and the government to change the way we recycle. More information is available in the January 2023 article “Technical, Economic, and Environmental Comparison of Closed-Loop Recycling Technologies for Common Plastics,” published in ACS Sustainable Chemistry & Engineering.
