Abstract :
Para-arsanilic acid (p-ASA) is widely used as a feed additive, making it a pervasive environmental pollutant. Due to its migratory and transformative nature, p-ASA can easily convert into more toxic inorganic arsenic during its migration, thereby increasing the ecological burden and posing a threat to human health. Efficient removal of p- ASA from water is crucial for mitigating arsenic contamination. Efficient removal of p-ASA from water is crucial for mitigating arsenic contamination. This study introduced zirconium-loaded collagen fiber membrane (CFM-Zr), a novel, sustainable membrane adsorption material synthesized by retanning collagen fiber membranes (CFM) with zirconium (Zr). Leveraging the physicochemical properties of CFM and the strong affinity of Zr forp-ASA, CFM-Zr achieved highly efficient p-ASA removal. The resulting membrane was made entirely from green, low-carbon and recyclable raw materials, achieving sustainable removal of p-ASA while realizing the concept of treating waste with waste for environmental recovery. Remarkably, the retanning with zirconium significantly enhanced the Zeta potential of CFM-Zr, strengthening its electrostatic attraction to p-ASA, with a maximum adsorption capacity of 289.02 mg & sdot;g- 1, which was 19.72 times higher than that of the CFM before retanning (13.95 mg & sdot;g-1). Its adsorption rate constant was 12.54 mg & sdot;g-1 & sdot;min- 1. Moreover, CFM-Zr showed good reusability and exhibited electrostatic adsorption and metal coordination effects on the "organic" parts (-OH,-NH2) and "inorganic" parts (As-O) of p-ASA, effectively removing it. This work provided a promising bio-based material for water purification, promoted the sustainable utilization of leather industry waste, and offered significant advancements in environmental remediation and resource recovery.

Abstract :
China generates over 100 million tons of food waste annually, leading to significant environmental pollution and health risks if not managed properly. Converting FW into a high-value-added platform molecule, lactic acid (LA), through fermentation offers a promising approach for both waste treatment and resource recovery. This paper presents a comprehensive review of recent advancements in LA production from FW, focusing on pure strains fermentation and open fermentation technologies, metabolic mechanisms, and problems in fermentation. It also assesses purification methods, including molecular distillation, adsorption, membrane separation, precipitation, esterification and hydrolysis, solvent extraction, and in-situ separation, analyzing their efficiency, advantages, and disadvantages. However, current research encounters several challenges, including low LA yield, low optical purity of L-(+)-LA, and difficulties in the separation and purification of LA. The integration of in-situ separation technology coupled with multiple separation methods is highlighted as a promising direction for future advancements.

Abstract :
Eucommia ulmoides gum (EUG) with high purity was extracted directly from the Eucommia ulmoides pericarp using a biphasic solvent system consisting of deep eutectic solvent (DES) and petroleum ether. The addition of DES enabled the deconstruction of lignocellulose and the exposure of EUG, leading to the efficient dissolution of EUG in petroleum ether. The extraction rate of EUG was 22.986 %, and the purity of EUG was 98.01 %. The chemical structure of EUG was confirmed by FTIR and NMR characterization. XRD and DSC analysis reviewed the partial destruction of crystal structure and the decline of beta- crystal phase of EUG during the extraction process. Moreover, the extracted EUG exhibited high tensile strength of 10.360 MPa, excellent elongation at break of 78.663 % ascribed to the unique crystallinity that enhanced the flexibility of molecular chains. In addition, the recycling performance of DES and petroleum ether was verified, and the recovery rate were up to 94.04 % and 82.60 %, respectively, indicating that this method is expected to replace the traditional pretreatment method for extracting EUG.

Abstract :
Extracting uranium from seawater has become an important method to supplement the nuclear industry. Herein, we introduce a simple route to load conjugated microporous polymers onto collagen fiber membranes, resulting in a novel membrane adsorbent material (CMPA-F/CFM) for uranium capture. Its Langmuir adsorption capacity reaches 304.9 mg center dot g-(- 1) (at 318 K), with fast adsorption kinetic of 60 min, and excellent adsorption selectivity with Kd d = 4.69 x 104 4 mL center dot g-(- 1) under the temperature of 298 K, initial concentration of 50 mg center dot L-1,-1 , and pH = 7, thus allowing a satisfactory adsorption performance in a 7-day real ocean experiment with a uranium adsorption capacity of 1.25 mg center dot g-1.(-1 ). Furthermore, in continuous dynamic adsorption experiments, CMPA-F/CFM could treat up to 19.0 L center dot g(-1-) 1 of low-enriched uranium (LEU) solution (1 mg center dot L-1),-1 ), with a uranium removal rate of up to 87.5 % (10 L of seawater). This study demonstrates broad potential application of membrane adsorption in extraction of low-enriched uranium.

Abstract :
As an emerging micropollutant, p-arsanilic acid (p-ASA) would release highly toxic arsenate and arsenite during migration transformation. Herein, a three-dimensional polyethylenimine-aminated leather collagen fiber (CF-PEI) decorated with MgZnFe (MZF) metal oxides, i.e., CF-PEI@MZF monolith, was reported for the ultradeep p-ASA removal. The synergetic functions of hydrogen bonding and electrostatic interaction from the CF-PEI and coordinative interaction from the MZF on the monolith allow an ultrarapid kinetic that could achieve ca. 80% of the adsorption equilibrium within 20 min and a benchmarked exothermic Langmuir adsorption capacity as high as 588.24 mg g(-1) for the p-ASA. It also performed an unparalleled feasibility in the continuous treatment to reduce the concentration of p-ASA to below 0.05 mg L-1 for real applications. We also highlight the monolith structure with great features of easy separation and recycling use for real industrial applications. All these demonstrate the merits of our CF-PEI@MZF monolith in addressing environmental engineering challenges.

Abstract :
An annual production of about 500 million tons of household food waste (HFW) has been documented, resulting in significant implications for human health and the environment in the absence of appropriate treatment. The anaerobic fermentation of HFW in an open system offers the potential to recover high value-added products, lactic acid (LA), thereby simultaneously addressing waste treatment and enhancing resource recovery efficiency. Most of LA fermentation studies have been conducted under mesophilic and thermophilic conditions, with limited research on the production of LA through anaerobic fermentation under hyperthermophilic conditions. This study aimed to produce LA through anaerobic fermentation from HFW under hyperthermophilic conditions (70 +/- 1 degrees C), while varying pH values (5.0 +/- 0.1, 7.0 +/- 0.1, and 9.0 +/- 0.1), and compare the results with LA production under mesophilic (35 +/- 1 degrees C) and thermophilic (52 +/- 1 degrees C) conditions. The findings of this study indicated that the combination of hyperthermophilic conditions and a neutral pH (pH7_70) yielded the highest concentration of LA, measuring at 17.75 +/- 1.51 g/L. The mechanism underlying the high yield of LA at 70 degrees C was elucidated through the combined analysis of organics dissolution, enzymes activities, and 16S rRNA microbiome sequencing.
