“…The biochar was natural slow‐pyrolyzed wood charcoal, commonly found in the market for several applications. General characteristics reported for biochars with similar origins are: high carbon contents (78–84%), low sulfur proportions (0.1–0.5%), high pH of the water‐extractable fraction (8.6–9.6), Brunauer–Emmett–Teller surface areas of 130–210 m 2 g −1 and relatively high conductivities (4–5 µS cm −1 g −1 ) . Before utilization, the biochar was ground and sieved at 600 µm.…”

“…43 Also the direct degradation of HPr and HBu has been improved by supplementing biochar and ethanol. 44 Sunyoto et al 47 observed that biochar supplementation increased the methane production rates and enhanced the consumption of HAc and HBu in the second stage of a 2-phase AD reactor treating aqueous FW. In the single other study dealing with biochar addition during FW AD, biochar supplementation improved the kinetics of methane production in batch reactors, dividing by two the lag phases and increasing the maximum methane production rates.…”

BACKGROUND Although anaerobic digestion is a promising alternative for the valorization of complex substrates such as food waste, this process is yet to be optimized and options for its stabilization must be developed. This study assessed for the first time if the combined addition of biochar and trace elements in the form of an industrial FeCl3 solution could serve as a method for stabilizing food waste anaerobic digestion. Both batch and long‐term semi‐continuous reactors were run. RESULTS Results from batch reactors demonstrated that supplementation of both biochar (10–100 g L−1) and trace elements (FeCl3; 0.1–0.2 g Fe L−1) favored the digestion kinetics. Their addition improved the maximum methane production rates (from 897 up to 1494 mL day−1) and the average daily methane production rates (from 298 up to 369 mL day−1), related to acetate and propionate consumption, respectively. Continuous reactors confirmed the batch results, with higher methane production rates (up to 1.75 L L−1 day−1) and lower concentrations of acetate and propionate when biochar and trace elements (FeCl3) were added. CONCLUSION Addition of biochar and industrial FeCl3 favored the digestion kinetics, improving volatile fatty acid consumption and methane production rates. These materials appear as an economically‐feasible alternative for stabilizing the valorization of food waste at industrial scale. © 2018 Society of Chemical Industry

In this work, we explore the use of biochar as a remediation agent, and the sensitivity of the spectral‐induced polarization method as a remediation monitoring aid. Biochar amended columns were fully saturated with industrial wastewater (olive oil mill waste) with very high concentration of phenols (∼2485 mg/L) and other substances. The biochar‐amended columns achieved very high removal rates of phenols compared to the control (sand only). Geophysical monitoring over the duration of the experiment (10 days) showed changes in the spectral‐induced polarization signal (imaginary conductivity) consistent with phenol removal as confirmed by geochemical monitoring. This experiment confirmed the utility of biochar as a remediation agent. Furthermore, spectral‐induced polarization can serve as long‐term, high resolution, monitoring aid in organic contaminant degradation processes.

“…However, revised methane yields showed that energy recovery raised from 0.53 (without algae) to 0.66 (with algae). Sunyoto et al (2016) improved hydrogen and methane yield from aqueous carbohydrates food waste by adding biochar. Bench-scale experiments were undertaken in two-phase anaerobic bioreactors.…”
