The U.S. Department of Energy (DOE) announced on May 24, 2023, the launch of the Clean Fuels & Products Shot^TM, a new initiative that aims to reduce significantly greenhouse gas emissions (GHG) from carbon-based fuels and products. DOE notes that this is its seventh DOE Energy Earthshot, which focuses on reducing carbon emissions from the fuel and chemical industry through alternative, more sustainable sources of carbon to achieve a minimum of 85 percent lower GHG emissions as compared to fossil-based sources by 2035. According to DOE, the Clean Fuels & Products Shot^TM supports the national goal of achieving net-zero emissions by 2050 by developing the sustainable feedstocks and conversion technologies necessary to produce crucial fuels, materials, and carbon-based products that are better for the environment than current petroleum-derived components. It aims to meet projected 2050 net-zero emissions demands for 100 percent of aviation fuel; 50 percent of maritime, rail, and off-road fuel; and 50 percent of carbon-based chemicals by using sustainable carbon resources.
 
DOE notes that a ribbon-cutting took place on May 30, 2023, for the Biofuels National User Facility, a $15 million, three-year-long facility upgrade at Idaho National Laboratory funded by DOE’s Bioenergy Technologies Office (BETO) and an important asset to reach the goals of the Clean Fuels & Products Shot^TM. According to DOE, the facility “is designed to solve critical biofuels production challenges associated with the feeding, handling and preprocessing of diverse biomass and waste materials.” DOE states that industry use of the facility “will enable rapid technology development and large-scale commercialization of biofuels and bioproducts, an important component of the Biden-Harris Administration’s goals related to clean fuels and products.”

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

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.

Colorado State University (CSU) announced on April 11, 2023, that its chemists, led by Eugene Chen, University Distinguished Professor in the Department of Chemistry, have created a synthetic polyhydroxyalkanoate (PHA) platform. CSU states that PHAs are a class of polymers naturally created by living microorganisms or synthetically produced from biorenewable feedstocks. While they are biodegradable in the ambient environment, they are brittle and cannot easily be melt-processed and recycled. According to CSU, the synthetic PHA platform addresses each of these problems, “paving the way for a future in which PHAs can take off in the marketplace as truly sustainable plastics.”
 
The researchers searched for a strategy to address the intrinsic thermal instability of conventional PHAs. According to CSU, its chemists “made fundamental changes to the structures of these plastics, substituting reactive hydrogen atoms responsible for thermal degradation with more robust methyl groups. This structural modification drastically enhances the PHAs’ thermal stability, resulting in plastics that can be melt-processed without decomposition.” CSU notes that the newly designed PHAs are also mechanically tough, “even outperforming the two most common commodity plastics: high-density polyethylene -- used in products like milk and shampoo bottles -- and isotactic propylene, which is used to make automotive parts and synthetic fibers.” CSU notes that the new PHA can be chemically recycled back to its building-block molecule with a simple catalyst and heat, and the recovered clean monomer can be reused to reproduce the same PHA again.
 
The work was supported by the U.S. Department of Energy’s (DOE) Bio-Optimized Technologies to keep Thermoplastics out of Landfills and the Environment (BOTTLE™), a DOE multi-organization consortium “focused on developing new chemical upcycling strategies for today’s plastics and redesigning tomorrow’s plastics to be recyclable-by-design.” More information is available in a Science article entitled “Chemically circular, mechanically tough, and melt-processable polyhydroxyalkanoates.”

As reported in our September 13, 2022, blog item, President Joseph Biden signed an Executive Order (EO) on September 12, 2022, creating a National Biotechnology and Biomanufacturing Initiative “that will ensure we can make in the United States all that we invent in the United States.” On March 22, 2023, the White House Office of Science and Technology Policy (OSTP) published a fact sheet announcing “new bold goals and priorities that will catalyze action inside and outside of government to advance American biotechnology and biomanufacturing”:

• Harnessing Biotechnology and Biomanufacturing Research and Development (R&D) to Further Societal Goals: On March 22, 2023, OSTP released a new report, Bold Goals for U.S. Biotechnology and Biomanufacturing: Harnessing Research and Development to Further Societal Goals, outlining a vision for what is possible with the power of biotechnology and biomanufacturing and the R&D needs to achieve this ambitious vision. Biden’s EO called on federal departments and agencies to assess the potential for biotechnology and biomanufacturing R&D to further five societal goals: climate change solutions; food and agricultural innovation; supply chain resilience; human health; and crosscutting advances. The report includes individual sections authored by the Department of Energy (DOE), the U.S. Department of Agriculture (USDA), the Department of Commerce (DOC), the Department of Health and Human Services (DHHS), and the National Science Foundation (NSF), in consultation with other agencies and departments, that are responsive to the President’s EO. The goals and R&D needs outlined in the report serve as a guide for public- and private-sector efforts to harness the full potential and power of biotechnology and biomanufacturing to develop innovative solutions in different sectors, create jobs at home, build stronger supply chains, lower costs for families, and achieve our climate goals. According to the fact sheet, OSTP will now lead the development of an implementation plan to address the R&D needs outlined in the report.
   
• Establishing Biomanufacturing Priorities for DOD: As part of the National Biotechnology and Biomanufacturing Initiative, DOD announced in September 2022 an investment of $1.2 billion in bioindustrial domestic manufacturing infrastructure to catalyze the establishment of a domestic bioindustrial manufacturing base accessible to U.S. innovators. On March 22, 2023, DOD released its Biomanufacturing Strategy to guide these investments, and its broader efforts in this critical technology field. This strategy, which will guide research efforts and collaboration with the private sector and allies, sets three key priorities: establishing the customers within DOD that stand to benefit from early-stage innovations, advancing biomanufacturing capabilities through innovation, and mapping the biomanufacturing ecosystem and tracking metrics that support future efforts. In support of the strategy, DOD issued a formal request for information on biomanufactured products and process capabilities that could help address defense needs and whose development and commercialization could be addressed by DOD investment.
   
• Assessing the Economic Value of the Nation’s Bioeconomy: DOC’s Bureau of Economic Analysis released a new report that assesses the feasibility of measuring the economic contributions of the U.S. bioeconomy. The report also includes an assessment of what is needed to measure these contributions better and more accurately.

According to the fact sheet, other deliverables from the EO are in development, including: a plan to expand training and education opportunities for the biotechnology and biomanufacturing workforce, a report on data needs for the bioeconomy, a national strategy for expanding domestic biomanufacturing capacity, actions to improve biotechnology regulation clarity and efficiency, and a plan for strengthening and innovating biosafety and biosecurity for the bioeconomy.
