This study examined waste Rontgen ray film (WRF) and silane-treated golden apple kernel (GAK) as possible co-feedstock materials for co-pyrolysis, which produces bioenergy, in a biorefinery setting. Kinetic behavior and thermodynamic characteristics of the GAK with WRF blend were assessed using non-isothermal thermogravimetric tests at heating rates (HT) of 5, 10, 15, and 20°C/min. Three iso-conversional models, such as Kissinger–Akahira–Sunose (KAS), Starink (SI), and Flynn–Wall–Ozawa (FWO) were used to calculate the activation energy (Ea), enthalpy (ΔH), entropy (ΔS), and Gibbs free energy (ΔG) of the co-pyrolysis process. The KAS, SI, and FWO models estimated average activation energies of 181.59, 189.61, and 179.77 kJ/mol, correspondingly, with corresponding coefficients of determination (R2) of 0.92, 0.92, and 0.91. The average thermodynamic parameters were ΔH = 146.51 kJ/mol, ΔS = 21.66 J mol−1 K−1, and ΔG = 119.54 kJ/mol. The co-pyrolysis process is not spontaneous in the conditions under study, according to these kinetic and thermodynamic parameters. All things considered, the results show that the GAK: WRF blend has advantageous thermal and energy properties, underscoring its potential as a sustainable waste-to-energy alternative biomass fuel.","PeriodicalId":11701,"journal":{"name":"Environmental Progress & Sustainable Energy","volume":"45 4","pages":""},"PeriodicalIF":2.6,"publicationDate":"2026-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148811283","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We report here the synthesis of a recyclable functionalized magnetic coconut fruit shell biochar (CFS-MBC) and chitosan-modified magnetic biochar (CFS-CSMBC) for polystyrene microplastics (PSMPs) removal from an aqueous medium. The characteristics of CFS-MBC and CFS-CSMBC were systematically investigated by using Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). In the batch adsorption study, at pH 3, the amount of adsorbent, exposure time 0.6 g and 40 min with PSMPs (80 mg/L concentration) exhibited maximum 91% PSMPs adsorption with CFS-CSMBC. The experimental findings of adsorption isotherm and kinetics showed a better fit to the Langmuir isotherm and pseudo-second order models, respectively. Maximum adsorption capacity of 1.98 and 4.75 mg g−1 were reflected with CFS-MBC and CFS-CSMBC, respectively. The calculated thermodynamic functions clarified that the PSMPs adsorption phenomenon was spontaneous and exothermic in nature. Reusability investigation reflected that CFS-MBC and CFS-CSMBC retained high sorption ability for PSMPs even after five consecutive cycles. Phytotoxicity tests reported that CFS-MBC and CFS-CSMBC treated PSMPs solution enhanced growth and biochemical parameters of mustard plants, hence reflecting their practical application prospective. Hence, this study introduces CFS-MBC and CFS-CSMBC as an environmental-benign, highly efficient, multi-functional and recyclable sorbent for PSMPs removal from aqueous matrices.","PeriodicalId":11701,"journal":{"name":"Environmental Progress & Sustainable Energy","volume":"45 4","pages":""},"PeriodicalIF":2.6,"publicationDate":"2026-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148811294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Waste cooking oil is a very prominent and economical energy source for producing biodiesel as its use can greatly reduce waste whilst also generating a renewable and sustainable biofuel. In this work, an energy balance and an economic analysis of biodiesel production using both edible sunflower oil and waste cooking oil (WCO) were conducted. Two types of catalyst were studied: a homogeneous catalyst (KOH) and a heterogeneous catalyst (CaO derived from Noble Pectin seashells). The use of WCO for biodiesel production using CaO derived from Noble Pectin seashells was found to be an energy gain process, with a net energy gain of 8.64 MJ per liter of produced biodiesel and an energy use efficiency greater than 1. The total energy input and output were calculated as 36.18 and 44.82 MJ/L respectively. Moreover, the economic analysis of the process showed a benefit-to-cost ratio of 2.60. Hence, the use of WCO as a second-generation feedstock serves as a novel and cost-effective approach for the production of biofuels. Although studies, such as this one, prove the potential of WCO for biodiesel production on an economic and energy basis, several research gaps still remain before practical application can be adopted. Therefore, more research efforts are still required to study the use and application of WCO for biodiesel production on an industrial scale.","PeriodicalId":11701,"journal":{"name":"Environmental Progress & Sustainable Energy","volume":"45 4","pages":""},"PeriodicalIF":2.6,"publicationDate":"2026-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148811116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study was conducted to compare the degradation of vanillin using homogeneous and heterogeneous electro-Fenton (EF) processes. Initially, electrocatalytic characterization was performed on a cathode material synthesized by solvothermal deposition of cobalt ferrite (CoFe2O4) nanostructures onto a carbon felt (CF) substrate and compared with bare CF. Subsequently, the effectiveness of the CF@CoFe2O4 cathode material in vanillin oxidation was compared at different pH values and currents with the heterogeneous electro-Fenton process. The highest vanillin degradation and total organic carbon (TOC) removal were achieved at pH 3. Following a 3 h heterogeneous EF process at 50 mA, 100% degradation, and 74% TOC removal were achieved, while the electrode's performance remained unchanged after 5 reuses. This study reports the first-time use of a CF@CoFe2O4 cathode in the electro-Fenton degradation of vanillin, achieving faster and more efficient removal than a conventional CF cathode while ensuring stability, low metal ion leaching, and environmental compatibility for sustainable treatment of persistent organic pollutants. Vanillin degradation was further accelerated at pH 3 due to reduced mass transfer limitations, enhanced hydroxyl radical generation from controlled metal ion leaching, and a more efficient redox cycling of metal ions.","PeriodicalId":11701,"journal":{"name":"Environmental Progress & Sustainable Energy","volume":"45 4","pages":""},"PeriodicalIF":2.6,"publicationDate":"2026-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148811131","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The structural and functional properties of the synthesized materials were characterized using SEM, XRD, and FTIR. Although Cd exposure did not hinder lettuce growth, it significantly increased Cd concentrations in plant tissues. Under alkaline conditions, the application of Triple Super Phosphate reduced Cd levels from 57.7 to 39.4 mg kg−1. In acidic soil, treatments with nHAP derivatives lowered Cd concentrations from 64.7 to approximately mg kg−1. Likewise, in hydroponic systems, nHAP, nWHAP, and nRHAP significantly decreased Cd concentrations from 206 to <190 mg kg−1. Markedly, these amendments did not adversely affect the uptake of essential nutrients such as K, Ca, Mg, Fe, Zn, Cu, and Mn; in fact, Zn uptake improved under alkaline conditions. Overall, nHAP and its derivatives show promise in reducing Cd accumulation while maintaining plant nutritional balance.

FTIR analysis showed gelatin introduced amine and hydroxyl groups, enabling Cr(VI) complexation and hydrogen bonding. Gelatin also improved adsorbent recoverability, retaining >60% efficiency after four cycles.
