Abstract:Because of the increase in concentrated animal feeding operations, there is a growing interest in sustainable manure management. In this study, hydrothermal liquefaction (HTL) of dairy manure enhanced by various chemicals (NH 3 ·H 2 O, H 3 PO 4 , and glycerol) was proposed as a sustainable alternative for the dairy manure management. The applications of NH 3 ·H 2 O and H 3 PO 4 during HTL could significantly enhance the production of liquid chemicals. The addition of NH 3 ·H 2 O or glycerol increased the amounts of non-polar toluene, xylene, and other benzene-contained compounds, while the use of H 3 PO 4 produced high amounts of acids, pyridine, 3-methyl-pyridine, 2,6-dimethyl-pyrazine, 2-cyclopenten-1-ones, and phenols. The biochars produced via HTL showed a significant increase in the surface area/pore volume and relatively higher N, P, C, and other minerals, and may serve as a good soil amendment and nutrient source. The preliminary energy analyses showed that the energy consumption of this process might be reduced to 50% of the original energy content of the feedstock, and the energy payback period was about 3.5 years. Combining all advantages, HTL of dairy manure might increase the sustainability of the farming operation via producing energy products, fine chemicals, and biochars.

“…In recent years, an increasing effort has been made to decrease the use of fossil fuels by substituting them with green and sustainable alternatives [37,38,39,40,41,42,43,44,45,46,47,48] and thus reducing environmental, economic, and societal problems. On the other hand, the agri-food industry produces large quantities of byproducts that are abandoned and can cause potential environmental issues.…”

Deep Eutectic Solvents for Pretreatment, Extraction, and Catalysis of Biomass and Food Waste

Valorization of lignocellulosic biomass and food residues to obtain valuable chemicals is essential to the establishment of a sustainable and biobased economy in the modern world. The latest and greenest generation of ionic liquids (ILs) are deep eutectic solvents (DESs) and natural deep eutectic solvents (NADESs); these have shown great promise for various applications and have attracted considerable attention from researchers who seek versatile solvents with pretreatment, extraction, and catalysis capabilities in biomass- and biowaste-to-bioenergy conversion processes. The present work aimed to review the use of DESs and NADESs in the valorization of biomass and biowaste as pretreatment or extraction solvents or catalysis agents.

“…Starting as early as the 1970s but increasing significantly over the past decade, research groups at universities and national laboratories around the world have been investigating HTL of a variety of biomass feed types, such as woody biomass (Schaleger et al, 1982;Haarlemmer et al, 2016;Tran et al, 2017), plant biomass (Zhang et al, 2013;Zhu et al, 2015;Yan et al, 2016), food processing waste (Minowa et al, 1995;Yang et al, 2016;Posmanik et al, 2017), agricultural waste (Chan et al, 2014;Singh et al, 2015;Zhu et al, 2017), animal manure (Xiu et al, 2010;Theegala and Midgett, 2012), pulp/paper sludge (Xu and Lancaster, 2008), and algae Neveux et al, 2014;Faeth et al, 2016). Previous work in CHG over the same period has looked at conversion of agricultural waste (Pei et al, 2009) and industrial wastewater (Seif et al, 2016) to hydrogen.…”

Hydrothermal Liquefaction (HTL) and Catalytic Hydrothermal Gasification (CHG) proof-of-concept bench-scale tests were performed to assess the potential of hydrothermal treatment for handling municipal wastewater sludge. HTL tests were conducted at 300 to 350 °C and 20 MPa on three different feeds: primary sludge, secondary sludge, and digested solids. Corresponding CHG tests were conducted at 350 °C and 20 MPa on the HTL aqueous phase output using a ruthenium-based catalyst. Biocrude yields ranged from 25 to 37%. Biocrude composition and quality were comparable to biocrudes generated from algae feeds. Subsequent hydrotreating of biocrude resulted in a product with comparable physical and chemical properties to crude oil. CHG product gas methane yields on a carbon basis ranged from 47 to 64%. Siloxane concentrations in the CHG product gas were below engine limits. The HTL-CHG process resulted in a chemical oxygen demand (COD) reduction of > 99.9% and a reduction in residual solids for disposal of 94 to 99%.
