“…The oxygen content of GFW biocrude oil was 6.46 ± 0.14%, while SDW had a higher amount of 12.16 ± 0.30%, attributed to the higher amount of unsaturated fatty acids. To remove undesirable heteroatoms like oxygen, nitrogen, and sulfur, further upgrading of the HTL biocrude oil products, such as hydrotreating, is required to achieve drop-in transportation fuel quality . The HHV of the biocrude oils was 40.32 ± 0.07 MJ/kg for GFW and 38.57 ± 0.32 MJ/kg for SDW.…”

Pilot-scale hydrothermal liquefaction (HTL) of biowaste is a critical step toward commercialization of the HTL technology. Despite many HTL studies conducted with wet biomass, including food waste, few were performed with a pilot-scale continuous plug-flow reactor (PFR), with the biocrude yield and quality analysis based on dewatering (ASTM D2892 Annex X1). This paper describes the development and performance evaluation of a mobile pilot-scale HTL continuous PFR, with a processing capacity of 60 L/ h of wet feedstock and 6 L/h of biocrude production. The reactor system was designed for reaction conditions of up to 325 °C and 17.25 MPa. The reactor has a volume of 28.88 L with an additional counterflow heat exchanger volume of 18.07 L. Two types of food wastes, from a food processing plant and grocery store, were processed at 280 °C for 30 min, producing biocrude oil yields of 52.19 and 47.06 wt %, energy recoveries of 68.17 and 70.77%, and carbon recoveries of 66.91 and 64.78%, respectively. Due to its high feedstock capacity and reaction volume, large amounts of biocrude oil and post-HTL wastewater (PHW) were obtained from this pilot-scale reactor to allow downstream research on upgrading biocrude oil for transportation fuel as well as PHW treatment and nutrient recovery.

“…The five publications from this partnership are focused on progressing in refining the techniques for biocrude production using hydrothermal liquefaction methods. This project shows different experiments that they have done using different types of livestock and techniques (Stablein et al, 2020 ; Watson et al, 2021a , b ). One of the most interesting projects carried out is the one where they use food waste from a university campus and combine it with wastewater to produce biocrude (Aierzhati et al, 2021 ).…”

The challenges and consequences of climate change have brought together governments around the world to advance scientific knowledge and programmatic actions to develop mitigation strategies while promoting sustainable development. The United States and China—the countries with the highest science expenditures globally—have historically developed a range of joint international research collaborations. However, under the “America First” agenda put forth by the Trump Administration, bilateral diplomatic relations with China reached their highest confrontational peak. Under this scenario science diplomacy served as a catalyst to maintain scientific collaborations between both countries. In 2018, the US National Science Foundation and the China National Natural Science Foundation launched the InFEWS US-China program to promote collaborations to expand food, energy, and water nexus (FEW Nexus) research and applications. Over the past four years, 20 research projects have been awarded from the US side and 47 publications have been reported as research output. By carrying out a descriptive analysis of the InFEWS US-China research and scholarly outputs, we find evidence of the crucial role played by the Chinese scientific diaspora who led 65% of the projects awarded. We find that there is a generally good understanding of the interdependencies between FEW systems included in the project abstracts. However, in the InFEWS US-China scholarly outputs generated to date, there is a lack of usage of a clear FEW Nexus theoretical framework. Further research should address intentional policies that enhance the involvement of scientific diasporas in their home countries to better address climate, sustainability, and development challenges.

“…Generally, bottleneck of biomass resource utilization is the high moisture, low mass and carbon density, and low energy content. Considering the high cost of separation and treatment of water involved in biomass, new techniques are required to develop to meet reaction with both biowaste and water, and hydrothermal carbonization (HTC), liquefication (HTL), and gasification (HG) have got enough attention to replace the traditional pyrolysis pathways [3]. Compared with traditional thermal conversion pathways like high temperature or low temperature pyrolysis, microwave pyrolysis, flash pyrolysis, HTC conversion pathways have showed several advantages like the flexible regulation, high efficiency, and short cycle in biomass pretreatment, upgrading, and materials preparation [4,5].…”

Hydrothermal carbonization is highly applicable to high moisture biomass upgrading due to fact that moisture involved can be directly used as reaction media under subcritical-water region. With this, value-added utilization of hydrochar as solid fuel with high carbon and energy density is one of the important pathways for biomass conversion. In this review, the dewatering properties of hydrochar after the hydrothermal carbonization of biowaste, coalification degree with elemental composition and evolution, pelletization of hydrochar to enhance the mechanical properties and density, coupled with the combustion properties of hydrochar biofuel were discussed with various biomass and carbonization parameters. Potential applications for the co-combustion with coal, cleaner properties and energy balance for biowaste hydrothermal carbonization were presented as well as the challenges.
