This study provides a new emphasis for research on the valorization of biowastes into nanocatalyst and biorefineries to be integrated with petroleum bioupgrading and polluted water treatment. The response surface optimized batch transesterification of waste‐frying oil using methanol and sustainable animal bone valorized fluorapatite nanocatalyst (FAP) yielded approximately 97% biodiesel via a pseudo‐second‐order reaction with an efficient rate of 0.48 (mol L⁻¹)⁻¹min⁻¹ and activation energy of 13.11 kJ mol⁻¹. In a pioneering step, by‐products of the starch industry and the biodiesel transesterification process; corn‐steep liquor (CSL 0.2 g L⁻¹) and bioglycerol (6.24 g L⁻¹) as nitrogen and carbon sources, increased the dibenzothiophene biodesulfurization (BDS) efficiency of a novel biodesulfurizing Rhodococcus jialingiae strain HN3 (NCBI Gene Bank Accession No. MN173539) sixfold. Further, upon the application of such bioproducts in a batch BDS process (1/3 petro‐diesel/water) of 96 h; HN3 desulfurized 82.26% of 0.62 wt.% sulfur without affecting the petro‐diesel calorific value. In an attempt to reach zero waste, an auxiliary pioneering step was performed, where the spent waste FAP, after being efficiently used for four successive transesterification cycles, was applied to photo‐remediate 4‐nitrophenol polluted water under UV‐irradiation. Advantageously, the fresh and spent waste FAP recorded the same photodegradation capabilities. Where they obeyed the Langmuir–Hinshelwood kinetic model (R² ≥ 0.966) recording the same rate constants (k_app 0.032 min⁻¹) and were efficiently reused for four successive polluted‐water treatment cycles. © 2021 Society of Chemical Industry and John Wiley & Sons, Ltd

环境开垦中的动物骨骼富裕：生物柴油生产，石油柴油生物脱硫和废水光处理

这项研究为将生物废料增值到纳米催化剂和生物精炼厂以与石油生物降解和污水处理相结合的研究提供了新的重点。使用甲醇和可持续的动物骨骼增值的氟磷灰石纳米催化剂（FAP）对响应面进行优化的废油炸油分批酯交换反应通过伪二级反应产生了约97％的生物柴油，有效率为0.48（mol L ^-1）^-1 min ^-1和13.11 kJ mol ^-1的活化能。淀粉行业和生物柴油酯交换过程的副产物是开拓性的一步；玉米浸泡液（CSL 0.2 g L ^-1）和生物甘油（6.24 g L ^-1）作为氮源和碳源，将新型生物脱硫红球菌jialingiae菌株HN3（NCBI基因库登录号MN173539）的二苯并噻吩生物脱硫（BDS）效率提高了六倍。此外，在分批BDS工艺（1/3石油/水）中将此类生物产品应用96小时后；HN3对0.62 wt。％的硫中的82.26％进行了脱硫，而不会影响石油柴油的热值。为了达到零废物的目的，执行了一个辅助的开拓步骤，在将废废FAP有效地用于四个连续的酯交换循环后，将其应用于紫外线照射下光修复的4-硝基苯酚污染的水中。有利的是，新鲜和废FAP记录了相同的光降解能力。他们遵守Langmuir-Hinshelwood动力学模型的地方（R² ≥0.966）记录相同的速率常数（K_应用0.032分钟^-1）和四个连续污染的水的处理循环，有效地再利用。©2021化学工业协会和John Wiley＆Sons，Ltd
