On June 1, 2021, the Oak Ridge National Laboratory (ORNL) announced that its scientists have developed a novel solvent that results in a more efficient process to recover valuable materials from used lithium-ion batteries. According to ORNL’s press release, this new method supports a stable domestic supply chain for new batteries and keeps old ones out of landfills.
 
Currently, the recycling process of batteries involves smelting, which is an expensive, energy-intensive process that releases toxic gas. This new process developed by ORNL, however, recovers cathode materials and aluminum foils from lithium-ion batteries using a less hazardous solvent. It is a wet chemical process that uses triethyl phosphate to dissolve the binder material that adheres cathodes to metal foil. This process results in efficient recovery of cobalt-based cathodes and graphite, among other valuable materials, such as copper foils, that can be reused in new batteries. ORNL’s Ilias Belharouak stated that, in addition to repurposing materials, the new process reduces toxic exposure for workers. The full publication of ORNL’s study is available here.

On April 13, 2021, Montana State University (MSU) researchers from its Norm Asbjornson College of Engineering published an article entitled “Biomineralization of Plastic Waste to Improve the Strength of Plastic-Reinforced Cement Mortar.” The study evaluates calcium carbonate biomineralization techniques applied to coat plastic waste and improve the compressive strength of plastic-reinforced mortar (PRM), a type of plastic-reinforced cementitious material (PRC). In an effort to reduce the environmental impact of plastic pollution, the study tested two types of biomineralization treatments: enzymatically induced calcium carbonate precipitation (EICP) and microbially induced calcium carbonate precipitation (MICP). While MICP treatment of polyethylene terephthalate (PET) resulted in PRMs with compressive strength similar to that of plastic-free mortar, EICP-treated PET resulted in weaker strength than that of MICP. MICP treatment, however, affects differently the compressive strength of PRM in various types of plastics. According to the researchers, further work is needed to understand the impact of MICP treatment on interfacial strength. The authors hope that greater knowledge of this mechanism will lead to the establishment of biomineralized PRC as a high-volume method to reuse plastic waste.

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.

On April 28, 2021, University of York researchers announced the discovery of a new enzyme derived from a fungus called Parascedosporium putredinis NO1, that can act as a catalyst for a biochemical reaction that breaks down forestry and agricultural waste.  The research was done in collaboration with DOE’s Great Lakes Bioenergy Research Center and the University of Wisconsin.  This development, according to the University of York, could play a key part in upscaling renewable fuels and chemicals.  Professor Neil Bruce explained that this discovery is a breakthrough because, currently, there are no industrial biocatalytic processes for breaking down lignin, which is present in lignocellulose.  This enzyme, however, can break through the lignin to begin the degradation process needed to produce biofuels.  Professor Bruce elaborated that the “treatments with this enzyme can increase the digestibility of lignocellulosic biomass, offering the possibility of producing a valuable product from lignin while decreasing processing costs.”

On March 25, 2021, researchers from the University of Maryland Department (UMD) of Materials Science and Engineering (MSE) published, in Nature Sustainability, a study titled “A strong, biodegradable and recyclable lignocellulosic bioplastic.”  The study outlines UMD MSE’s new in situ lignin regeneration strategy that synthesizes a high-performance bioplastic from lignocellulosic resources such as wood.  According to the published article, renewable and biodegradable materials derived from biomass often exhibit mechanical performance and wet stability that are insufficient for practical applications.  Given these circumstances, the newly developed method for bioplastic production improves efficiency and reduces environmental impacts because it involves only green and recyclable chemicals.  The study can be accessed here, detailing the process in which porous matrices of natural wood are deconstructed to form the lignocellulosic bioplastic.


 

From June 14 through 18, 2021, the American Chemical Society Green Chemistry Institute (ACS GCI) will host its annual Green Chemistry & Engineering Conference.

On March 2, 2021, the University of Southern California (USC) Wrigley Institute for Environmental Studies on Santa Catalina Island announced a new aquaculture technique that increases dramatically kelp growth and, consequently, yields four times more biomass than other natural processes. Using a “kelp elevator,” this new technique optimizes growth for bronze-colored floating algae by raising and lowering it to different depths. These findings suggest that the use of open ocean to grow kelp biomass for biofuel production can serve as a solution to the generation of biofuels from feedstocks such as corn and soybeans, which often increase water pollution. Corresponding author of the study, Diane Y. Kim, Ph.D., stated that “[f]orging new pathways to make biofuel requires proving that new methods and feedstocks work. This experiment on the Southern California coast is an important step because it demonstrates kelp can be managed to maximize growth.”
