Bio-green synthesis of calcium acetate from oyster shell waste at low cost and reducing the emission of greenhouse gases
Sustainable Environment Research - Tập 33 - Trang 1-11 - 2023
Biological wastes obtained from food, oyster shells, were recycled to calcium carbonate and then used as bio-green raw material to replace limestone/carbonate stone for calcium acetate (Ca(CH3COO)2·H2O) production. The conditions (ambient temperature occurred in an exothermic reaction, drying time, yield, and solubility) of the reaction between the bio-green CaCO3 and three different acetic (CH3CO......
Competitive photo-degradation performance of ZnO modified bentonite clay in water containing both organic and inorganic contaminants
Sustainable Environment Research - Tập 29 - Trang 1-12 - 2019
This study reports the activity difference of zinc oxide modified bentonite clay (Photo-Zn-Bent) photocatalyst when in contact with different environmentally toxic pollutants in a single component and bi-component pollutant systems. The layered structure of purified and swollen nano-bentonite clay (Bent) has tunable interlayer spacing to grow zinc oxide (ZnO) nanoparticles, thereby integrating the......
CFD and experimental studies on capture of fine particles by liquid droplets in open spray towers

Identifying groundwater recharge zones using remote sensing & GIS techniques in Amaravathi aquifer system, Tamil Nadu, South India
Sustainable Environment Research - Tập 29 - Trang 1-9 - 2019
In order to increase the sustainability of the wells and arrest the declining groundwater level trends in Amaravathi aquifer system, southern India, remote sensing and geographic information system (GIS) approach was attempted to identify favourable regions for construction of artificial recharge structures. GIS overlay analysis was carried out wherein 8 layers viz. geology, geomorphology, slope, ......
Fertilization-induced reactive nitrogen gases and carbon dioxide emissions: insight to the carbon-nitrogen cycles
Sustainable Environment Research - Tập 33 - Trang 1-12 - 2023
Different agricultural practices can pose significant threats to environmental quality and human health. This study aimed to assess the emissions of reactive nitrogen (NH3, NOx, and N2O) and carbon dioxide (CO2) induced by fertilization in spinach and cabbage farmlands. Field and pot experiments were conducted to analyze the emission fluxes and intensities of reactive nitrogen gases and CO2. The f......
Implementing circular economy concept by converting cassava pulp and wastewater to biogas for sustainable production in starch industry
Sustainable Environment Research - Tập 31 - Trang 1-12 - 2021
Adoption of the circular economy concept to utilize wastes and by-products from the cassava starch industry for biogas production has been considered a viable option. The annual generation of wastewater and cassava pulp in Thailand is reported to be approximately 21 million m3 and 9.5 Mt, respectively. This research therefore aimed to analyze the key drivers and challenges in implementing the circ......
Electrochemical degradation of methylene blue accompanied with the reduction of CO2 by using carbon nanotubes grown on carbon fiber electrodes
Sustainable Environment Research - Tập 32 - Trang 1-14 - 2022
In this study, the degradation of Methylene Blue (MB) dye accompanied with the reduction of CO2 was performed in an electrochemical (EC) process by using carbon nanotubes grown on carbon fiber (CNTs/CFM) electrodes as the cathode and anode in a two-compartment electrochemical cell. The growth of CNTs on CFM via chemical vapor deposition led to the significant improvement in physicochemical propert......
Sulfolane degrading bacteria from petrochemical plant: activated sludge enrichment, isolation and characterization
Sustainable Environment Research - Tập 33 - Trang 1-9 - 2023
Sulfolane is extensively used as an extractive solvent in sour-gas processing plants in the petrochemical industry. After repeated use, deteriorated sulfolane becomes corrosive and may leak into the environment to threaten aquatic and terrestrial organisms or cause shock loading of wastewater treatment systems. It is therefore important to remove sulfolane from the environment and maintain stable ......
Stability evaluation of a grid-tied hybrid wind/PV farm joined with a hybrid energy-storage system
Sustainable Environment Research - - 2023
This paper presents the stability-evaluation outcomes of a multimachine power system (MMPS) connected with a large-scale hybrid wind farm (WF) and photovoltaic (PV) farm or hybrid wind/PV farm (HWPF) and a hybrid energy-storage system (HESS) consisting of a vanadium redox flow battery (VRFB) and a supercapacitor (SC). A probability scheme is used to determine the rated power of the proposed HESS, ......
Techno-economic analysis and environmental impact of biovalorization of agro-industrial wastes for biodiesel feedstocks by oleaginous yeasts
Sustainable Environment Research - Tập 30 - Trang 1-13 - 2020
Different types of agro-industrial wastes including lignocellulosic wastes, carbohydrate and protein-rich wastes, syrup wastes and glycerol wastes were explored as biodiesel feedstocks. This strategy not only can partially replace fossil fuel but also simultaneously decrease the environmental impact. This is the first report on the techno-economic analysis and CO2 emissions of biovalorization of t......
