Precision agriculture, soil carbon sequestration, and biorefining couple circularity with carbon negativity. Stakeholders from many disciplines are needed to successfully couple circularity with carbon negativity. Abstract. Achieving a circular economy is critical for a sustainable future, particularly in sectors that currently produce resource-intensive products in a linear fashion, such as food and agriculture. At the same time, technologies that remove atmospheric CO2, often referred to as carbon dioxide removal (CDR) or carbon negativity, must be developed and deployed rapidly if we are to avoid the worst effects of climate change. Circularity and CDR are often assessed and discussed independently, even though they are highly intertwined. Innovations to food and agriculture systems are essential to achieving a circular economy and enabling rapid deployment of CDR technologies. We explore critical areas of technology that must undergo rapid innovation (upstream and downstream) to food processing and consumption, namely precision and regenerative agriculture and biorefining, respectively. If implemented at scale, these two areas of technology have the potential to couple circularity with carbon negativity in food production systems.

Agricultural emissions are caused both by fossil-intensive fertilizer use and land-use change, which in turn are driven in part by increasing demand for dietary protein. To address this challenge, we present a synergistic system in which organic waste-derived biogas (a mixture of methane and carbon dioxide) is converted to dietary protein and ammonia fertilizer. This system produces low-carbon fertilizer inputs alongside high-quality protein, addressing the primary drivers of agricultural emissions. If the proposed system were implemented across the United States utilizing readily available organic waste from municipal wastewater, landfills, animal manure, and commercial operations, we estimate 30% of dietary protein intake and 127% of ammonia usage could be displaced while reducing land use, water consumption, and greenhouse gas emissions.}, journal={BIORESOURCE TECHNOLOGY}, publisher={Elsevier BV}, author={Sagues, William J. and Assis, Camilla A. and Hah, Phillip and Sanchez, Daniel L. and Johnson, Zackary and Acharya, Madhav and Jameel, Hasan and Park, Sunkyu}, year={2020}, month={Feb} } @article{bao_sagues_wang_peng_zhang_yang_xiao_tong_2020, title={Depolymerization of Lignin into Monophenolics By Ferrous/ Persulfate Reagent Under Mild Conditions}, volume={10}, DOI={10.1002/cssc.202002240}, abstractNote={This study aimed to use a persulfate together with transition metal ions as the reagent to effectively depolymerize lignin into monophenolic compounds under mild conditions (ambient pressure, temperature <100 °C). The Box-Behnken experimental design in combination with the response surface methodology was applied to obtain optimized reaction conditions. The results showed that this reagent could depolymerize up to 99 % of lignin dimers to mainly veratraldehyde. This reaction also successfully depolymerized industrial lignins with a high yield of phenolic oils and monophenolic compounds. Quantum chemistry calculations using the density functional theory level indicated that the persulfate free radical attacks Cβ to break the β-O-4 bond of lignin through a five-membered ring mechanism. This mechanism using persulfate free radicals has a lower activation barrier than that using hydroxyl radicals. Gel permeation chromatography and 2D-NMR spectroscopy demonstrated the effective cleavage of the β-O-4 bonds of lignin after depolymerization.}, journal={ChemSusChem}, publisher={Wiley}, author={Bao, Hanxi and Sagues, William J. and Wang, Yigui and Peng, Wenbo and Zhang, Lin and Yang, Shunchang and Xiao, Dequan and Tong, Zhaohui}, year={2020}, month={Oct} } @article{sagues_jameel_sanchez_park_2020, title={Prospects for bioenergy with carbon capture & storage (BECCS) in the United States pulp and paper industry}, volume={13}, url={https://doi.org/10.1039/D0EE01107J}, DOI={10.1039/d0ee01107j}, abstractNote={The pulp and paper industry is a suitable candidate to lead the deployment of BECCS in the US.}, number={8}, journal={Energy & Environmental Science}, publisher={Royal Society of Chemistry (RSC)}, author={Sagues, W.

The model input parameters that differed among the hypothetical scenarios were fermentation time, enzyme loading, enzymatic conversion, solids loading, and overall process yield. The minimum ethanol selling price (MESP) varied between 50.38 and 62.72 US cents/L. The feedstock and the capital cost were the main contributors to the production cost, comprising between 23-28% and 40-49% of the MESP, respectively.
