“…Codigestion experiments were carried out with an organic loading of 2.5% FW to analyze the efficacy of codigestion in overcoming the limitations of high organic loadings observed (111.05 L·kg −1 VS) and PCG (94.87 L·kg −1 VS). The methane yields obtained in this study were comparable with values (80 to 530 L·kg −1 VS) reported by others for the same or similar agricultural and energy crops [39,[52][53][54]. Substrate concentrations of more than 1% w/v showed a significant decrease in methane production (P < 0.05).…”

Abstract:This article aims to study the codigestion of food waste (FW) and three different lignocellulosic wastes (LW) (Corn stover (CS), Prairie cordgrass (PCG), and Unbleached paper (UBP)) for thermophilic anaerobic digestion to overcome the limitations of digesting food waste alone (volatile fatty acids accumulation and low C:N ratio). Using an enriched thermophilic methanogenic consortium, all the food and lignocellulosic waste mixtures showed positive synergistic effects of codigestion. After 30 days of incubation at 60 • C (100 rpm), the highest methane yield of 305.45 L·kg −1 volatile solids (VS) was achieved with a combination of FW-PCG-CS followed by 279.31 L·kg −1 VS with a mixture of FW-PCG. The corresponding volatile solids reduction for these two co-digestion mixtures was 68% and 58%, respectively. This study demonstrated a reduced hydraulic retention time for methane production using FW and LW.

“…The resulting gains in vegetative biomass can provide economic returns when harvested. These can be realised, for example, through biogas production (Shiralipour and Smith, 1984), animal feed (Bagnall et al, 1974), fibre for paper making (Nolan and Kirmse, 1974) and compost (Parra and Hornstein, 1974).…”

a Herein, we report a remarkable finding that biomass oxidation to formic acid (FA) in water-organic biphasic reaction systems is far more selective than the same reaction in a monophasic aqueous media.While literature claims that the yield of FA from carbohydrates and biomass is limited to less than 68%, even for simple substrates such as glucose or glycerol, we demonstrate in this study that FA yields of up to 85% can be obtained from glucose. Using our biphasic reaction protocol, even raw lignocellulosic biomass, such as beech wood, leads to FA yields of 61%. This is realized by applying polyoxometalate H 8 PV 5 Mo 7 O 40 as a homogeneous catalyst, oxygen as the oxidant and water as the solvent in the presence of a long-chain primary alcohol as an in-situ extracting agent. The new, liquid-liquid biphasic operation opens a highly effective way to produce pure FA, a liquid syngas equivalent, from wood in a robust, integrated, and low-temperature process.
