Recovery of Nitrogen from Low-Cost Plant Feedstocks Used for Bioenergy: A Review of Availability and Process Order

The cost of feedstock is often a major barrier to commercialization for lignocellulosic biofuels. Much of the research on biofuel and biobased chemical production has focused on the carbohydrate, lignin, and lipid components of biomass. There are numerous opportunities for the use of lower-cost feedstocks if more attention were devoted to the recovery and utilization of the protein and other N-containing components. This review compiles data from the last two decades on nonedible/ nonpalatable agricultural residues, deoiled seedcakes, bioethanol and biogas residues, and food wastes, with a focus on the amounts and types of N-containing components. Given the challenges of removing N-containing compounds from biofuel intermediates postconversion, a case is made for the extraction and purification of proteins (and other N-containing compounds) from low-cost lignocellulosic biomass before conversion to fuel. The goal of such processes is to avoid difficult fuel upgrading steps while enhancing the opportunities for additional biorefinery products and sustainable nitrogen cycles.

“…This seedcake is made by removing the oil from the seed chemically or mechanically. The Jatropha pressed cake contains toxic materials, which disqualifies it from animal feed or natural fertilizer [13]. For example, project K007 in Galapagos Island ensures the sustainability of the diesel replacement used for electricity generation on Floreana Island with vegetable oil from the agro-industrial development of the 12,700 km of J. curcas existing as live fences in the Manabí province [14].…”

Anaerobic digestion is a method of agricultural residue transformation used in bioenergy, making these activities energy efficient. However, it can be limited on a larger scale by the availability and diversity of organic residues related to carbon-nitrogen (C/N). Therefore, the anaerobic co-digestion of bovine manure and Jatropha seed cake (Jatropha curcas) were evaluated, with three different C/N ratios, under two conditions: mesophilic (30ºC) and thermophilic (50ºC). Biodigesters were mounted with three replicates for each C/N ratio. The highest production of CH4 was registered after 30 days of processing in the thermophilic condition (C/N 25:1) with 633.95 ± 5.59 mL of CH4 g-1 VS. In contrast, the lowest production was in the mesophilic condition (C/N 20:1) with 208.66 ± 2.61 mL of CH4 g-1 VS. The feasibility of co-digestion of agricultural residues in the production of CH4 as a possible bioenergetic alternative in short periods was demonstrated.

“…Renewable biofuels from organic wastes have been discovered as energy sources that can substitute fossil fuels and lower greenhouse gas emissions. Biogas produced from anaerobic digestion of various organic wastes is one biofuel that can potentially replace these fuels with high carbon content ( Ogunkunle et al., 2018 ). An anaerobic digestion’s main benefits include combined energy and environmental effect.…”

A smart energy recovery process can achieve maximum energy recovery from organic wastes. Pretreatment of feedstock is essential to biogas and methane yields during the anaerobic digestion process. This work combined particle size reduction with Fe3O4 nanoparticles to investigate their influence on biogas and methane yields from anaerobic digestion of Arachis hypogea shells. Twenty milligrams per litre of Fe3O4 nanoparticles was implemented with 2, 4, 6 and 8 mm particle sizes and a single treatment of Fe3O4 for 35 days. The treatments were compared with each other and were discovered to significantly ( p < 0.05) enhance biogas yield by 37.40%, 50.10%, 54.40%, 51.40% and 35.50% compared with control, respectively. Specific biogas yield recorded was 966.2, 1406, 1552.7, 1317.4, 766.2 and 413 mL g−1 volatile solid. This study showed the combination of Fe3O4 with 6 mm particle size of Arachis hypogea shells produced the optimum biogas and methane yields. The addition of Fe3O4 to particle sizes below 6 mm resulted in over-accumulation of volatile fatty acids and lowered the gas yield. This can be applied on an industrial scale.
