Abstract China’s manufacturing industry faces the dual imperatives of supporting economic growth while reducing emissions to achieve national carbon neutrality targets. This study analyses the potential for decarbonisation across manufacturing sub-sectors. Using factor analysis and fuzzy comprehensive evaluation, it assesses industries based on foundational advantages, growth prospects, and sustainability. The results rank sub-sectors and identify promising areas like eco-friendly equipment and agricultural processing. However, carbon-intensive industries require urgent transformation. To optimise China’s industrial structure for low-carbon development, coordinated efforts across policy, industry, and enterprise are needed. Supportive regulations, industrial integration, and technology adoption can incentivise green manufacturing. By strategically promoting circular economy models, China can enhance quality and efficiency, convert waste into value, and contribute to global climate action. This study provides insights into aligning manufacturing growth with carbon neutrality in the new economic era.

Abstract The study took as a purpose to determine the Total Carbon (TC) content in the biomass, the Starch Carbon fraction (SC) and its annual dynamics in the biomass of perennial organs (stem and root) in adult trees of two of walnut tree ( Carya illinoinensis ). Four adult Western and Wichita tree stem and root samples were carried out monthly for a whole year. The TC was determined with an elemental analyser and the SC has gotten based on the molecular mass of the glucose (0.40 gC/gGlucose). t -Student test was performed between varieties per organ for the comparison of TC and SC through the program SPSS 15.0 with a significance of p ≤ 0.05. The results in Western variety were 160.02 kg TC and 4.90 kg SC to 7.54 kg SC in the stem; 64.58 kg TC and 1.74 kg SC to 3.09 kg SC in the root; in Wichita variety were presented 119.72 kg TC and 4.49 kg SC to 6.83 kg SC in the stem; 45.72 kg TC and 1.35 kg SC to 2.75 kg SC in the root. The root was the organ where the greatest amount of SC was stored in relation to the stem, due this latter constitutes a transport organ. Temperature has a marked inversely proportional influence on the accumulation of SC in both varieties. Global solar radiation and solar radiation proportionally influence the accumulation of SC.

Abstract Extreme hydrological events, such as floods and droughts, are becoming more frequent as a result of climate change, leading to negative impacts on various economic sectors. The Pannonian-Carpathian Basin is particularly affected by the increasing frequency of hazardous hydrological events. Agricultural production, which is a highly significant economic sector in the region, is particularly vulnerable to these unfavourable climatic conditions. Changes in precipitation patterns and soil moisture levels can lead to reduced crop yields, while floods can pollute water sources and erode fertile soil. Mapping of Inland Excess Water (IEW), also known as ponding water or waterlogged areas, is crucial for informed decision-making, damage compensation, risk management, and future prevention planning. Remote sensing technology and machine learning have been demonstrated to be valuable tools for the mapping of IEW. The 2014 floods in Southeastern and Central Europe serve as a reminder of the importance of effective flood risk management. This study used a Geographical Information System (GIS) and a Semi-automated Classification Processing (SCP) tool to process high-resolution RapidEye satellite images from the 2014 floods in the Srem region of Serbia. The Spectral Angle Mapping (SAM) classification model was used to produce a map of IEW. The SAM model achieved an overall accuracy of 92.68 %. The study found that IEW affected approximately 2.90 % or 99.59 km² of the territory in Srem. The obtained maps can be used by responsible water management agencies to prevent and control excessive inland water.

Abstract The study focused on the development of an environmentally friendly bioplastic material using sustainable seaweed-based biocomposites. Algal biomass ( Gracilaria edulis ) was processed and combined with starch, glycerol, glacial acetic acid, and chitosan to create flexible, homogenous biopolymer films. These films exhibited comparable physical properties to commercial plastics and retained their inherent colour post-processing. Spectroscopic analysis revealed intense UV-Vis peak points aligned with seaweed composition. Mechanical testing demonstrated adequate strength and flexibility, similar to starch-based bioplastics, with a tensile strength of 3.383 MPa and lower elongation strength of about 31.90 %. Material migration tests indicated a preference for water, suggesting suitability for low-moisture foods. The bioplastic film displayed notable biodegradability and compostability, showcasing its potential as a sustainable alternative for food packaging. This innovative contribution advances eco-friendly bioplastic material, addressing plastic pollution and promoting biocomposite use.

Abstract The research conducted here will hopefully lead to the creation of a practical, inexpensive method for purging aqueous solutions of contaminating phenolic chemicals. A biosorbent system comprised of eggshells and iron was studied for its potential to effectively detoxify phenol. Both the eggshell and the iron systems were used in the preparation of the adsorbents in order to achieve the desired result of having the properties of both systems. Scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), and X-ray diffraction (XRD) were used for characterisation. Batch tests were conducted to evaluate the adsorption capacity of eggshells and iron under the influence of different operating parameters (shaking speed, pH, initial phenol content, and contact time). In the design-expert modelling, the optimisation conditions were found to be a pollutant concentration = 30.0 mg . L – 1 , pH of 3.00, adsorbent dose = 0.11 mg . L – 1 , shaking speed = 150 rpm, and time = 120 min for an phenol reduction rate of 94.4 % which it was extremely near to the experimentally value (96.6 %). The CCD modelling that was performed in the RSM verified the findings that were predicted. On the basis of laboratory results, the prediction proved accurate.

Abstract The abandoned copper mine in the Moldova Noua area is still producing mining pollution today due to the drying of tailings ponds and the carrying of contaminated dust by the winds, leading to potential contamination of surface waters and groundwaters. The purpose of this study is the assessment of some surface waters and groundwaters potentially contaminated by mining pollutants from Moldova Noua area regarding their hydrochemical and ecotoxicological properties. The physicochemical parameters (pH, conductivity, dissolved oxygen, and turbidity) were determined in situ , with the concentrations of heavy metals (As, Cd, Cr, Cu, Fe, Mn, Ni, Pb, and Zn) being determined in the laboratory. Inhibition of acid phosphatase enzymatic activity and yeast toxicity tests were the two ecotoxicological tests used for the evaluation of mining pollution effects on the quality of surface waters and groundwater. The results highlighted that most of the physicochemical parameters and heavy metal concentrations were within normal limits. With the exception of the surface water sample collected from the Bosneag River, upstream of Moldova Noua, all samples induced inhibition compared to the positive control in the ecotoxicological tests applied. Statistically significant correlations were observed, with the total concentration of iron ions presenting the most statistically significant correlations with other parameters. A grading scale was used to assess the state of the waters, highlighting the weak impact of mining pollutants on the analysed samples.

Abstract Removal of residual tetracycline (TC) in the environment is an important issue for pollution control. In this study, a TC-degrading strain named JX_1 was isolated from the soil around an industrial park, the strain was identified as Burkholderia sp. by 16s rDNA sequencing analysis. The effects of various factors on TC degradation by the strain were studied, results indicated that the inoculation amounts and liquid volume had little effect on TC degradation rate. However, the degradation rate of TC by strain increased with the increase of pH, and the residual concentration increased gradually with the initial TC concentration increased. The degradation rate of 125 mg/L TC by strain JX_1 was 75.76 % under the conditions of temperature 37 °C, 2 mL inoculation amount and 200 mL liquid volume. Under the same conditions, the degradation rate of TC was increased to 91.39 % with the addition of 0.75 g/L MnSO 4 , indicating that Mn(II) could improve the degradation rate of TC by strain JX_1 to a certain extent.

Abstract One of the most important effluents in Guadiana Valley, Durango is El Tunal River, mostly used for agricultural and livestock supply. This river has been polluted by agricultural activity and wastewater discharges. Thus, this study aimed to evaluate the current quality of water and agricultural soil near the river, to estimate the environmental situation of the agricultural sector and its main pollution sources. Hence, a total of 24 soil and five water samples were taken, analysing parameters of organic matter, pH, nutrients, and heavy metals(loid)s (As, Cd, Pb, Zn) in five agricultural areas. The randomised experimental design showed significant variations in soil ( p < 0.05) of organic matter, nitrogen, As, and Pb between sampling points, confirming suitable conditions for agriculture. Although contamination by heavy metal(loid)s exists, it is below permitted levels. In contrast, the physicochemical quality of the water indicated high levels of phosphates, total dissolved solids, and total coliforms, mainly in the nearest site of a wastewater treatment plant, thus the quality of the water is not suitable for consumption and irrigation for sensitive crops. Nevertheless, rainfall contributes to improve the quality of the river by diluting pollutants. Moreover, constant use of this water might represent a risk to human health and agriculture as it could transport elements to crops or soil, becoming a severe environmental problem.
