The inedible parts of nuts and stone fruits are low‐cost and lignin‐rich feedstock for more sustainable production of aromatic chemicals in comparison with the agricultural and forestry residues. However, the depolymerization performances on food‐related biomass remains unclear, owing to the broad physicochemical variations from the edible parts of the fruits and plant species. In this study, the monomer production potentials of ten major fruit and nutshell biomass were investigated with comprehensive numerical information derived from instrumental analysis, such as plant cell wall chemical compositions, syringyl/guaiacyl (S/G) ratios, and contents of lignin substructure linkages (β−O−4, β−β, β−5). A standardized one‐pot reductive catalytic fractionation (RCF) process was applied to benchmark the monomer yields, and the results were statistically analyzed. Among all the tested biomass, mango endocarp provided the highest monolignol yields of 37.1% per dry substrates. Positive S‐lignin (70‐84%) resulted in higher monomer yield mainly due to more cleavable β–O–4 linkages and less condensed C–C linkages. Strong positive relationships were identified between β–O–4 and S‐lignin and between β–5 and G‐lignin. The analytical, numerical, and experimental results of this study shed lights to process design of lignin‐first biorefinery in food‐processing industries and waste management works.

“…Although the kukui seed is marketed as a natural weight-loss supplement, many adverse symptoms were reported, which may be associated with the presence of phorbol esters . Currently, the primary application is oil for the cosmetic industry in Hawaii and biodiesel production in Malaysia and Indonesia. ,− With the high oil content of the seeds, the potentially valuable caffeoyl alcohol monolignols or C-lignin-containing shells, , and the high-grade bioadsorbents derived from the shells, , kukui nuts have the potential to serve as a feedstock for sustainable aviation fuel (SAF) and high-value chemicals. A comprehensive understanding of its fuel characteristics can remove one limitation to the use of kukui nuts for SAF and chemical production .…”

Fuel properties of oil-bearing kukui (Aleurites moluccana) nuts, a commonly found crop in Hawaii and tropical Pacific regions, were comprehensively studied to evaluate their potential for bioenergy production. Proximate and ultimate analyses, heating value, and elemental composition of the seed, shell, and de-oiled seed cake were determined across five sampling locations in Hawaii. The aged and freshly harvested kukui seeds were found to have similar oil contents, ranging from 61 to 64%wt. Aged seeds, however, have 2 orders of magnitude greater free fatty acids than those freshly harvested (50% vs 0.4%). The nitrogen content of the de-oiled kukui seed cake was found to be comparable to that of the soybean cake. Aging of kukui seeds can decrease the flashpoint temperature and increase the liquid–solid phase transition temperatures of kukui oil obtained. Mg and Ca are the major ash-forming elements present in the kukui shells, >80%wt of all metal elements detected, which may reduce deposition problems for thermochemical conversion in comparison with hazelnut, walnut, and almond shells. The study also revealed that kukui oil has similar characteristics to canola, indicating that it is well-suited for biofuel production.
