The agricultural sector throughout the world has seen shifting significantly by suitably using e-technology. A good number of studies have been conducted on agriculture and food security. The growth rate of world organic farming or business increases to more than the growth rate of traditional agriculture. In Bangladesh the pace of growth of organic agriculture is insignificant. The organic agriculture or organic supply chain in Bangladesh was scarcely studied. Hence, an intensive study is needed for the organic agriculture industry to pursue the organic supply chain that leads to a promising growth of organic business. A great deal of research has been conducted to explore the factors that may influence the organic supply chain and growth of the organic business. Several theories such as the diffusion of innovation theory, theory of planned behavior, marketing system and price of organic products, and quality function deployment have been studied and proposed to enhance the understanding of the issue. The integration of all these literature and theories has attracted the researcher’s attention. Thus, this study aims to explore the influence of information systems, e-technology, and the dynamics of the actors (consumer, retailer, intermediaries, transporter, farmer, and basic suppliers) on the organic supply chain enhancing the growth of the organic business. By adopting secondary data with collected data (primary data) using self-administrated questionnaires the research work was evaluated. A total of 389 responses from the organic agriculture industrial actors, consumers, and transporters were collected using stratified random sampling methods. To inspect and analyze data, Path Analysis and Structural Equation Modeling (SEM) techniques were used with AMOS. The results of the study indicated that the proposed model provided a good understanding of the factors influencing the organic supply chain. From the result, it was also revealed that the organic supply chain has a significant impact on the growth of organic farming and organic consumers and the performance of organic businesses. The research objectives of this study were accomplished and all research hypotheses were supported. This study theoretically offers useful information and collected data might help to further research relevant to the organic supply chain. In addition, the study finds a way to foster a better understanding and knowledge of the organic supply chain. It is encouraged to do future research to study the factors and information and impact of the organic supply chain from various aspects.Keywords: organic supply chain, e-technology, organic agriculture, growth of organic business, SEM, AMOS

“…Zirconium dioxide (or Zircania, ZrO 2 ) as broad bandgap (3.25-5.1 eV) semiconductor has been widely explored due to the presence of a large number of O 2 vacancies on the surface, significant ion exchange ability and physiochemical stability [91]. ZrO 2 NPs possesses a high value of the dielectric constant, tensile strength, melting and boiling point, however, its wide band gap and low separation rate of photogenerated electron and hole hinder the wide-scale applications [92]. To overcome this, various enhancement strategies like doping, heterojunction formation incorporation of cocatalysts, etc., have been potentially explored.…”

“…Recent research has manifested that zirconia-based materials show high redox abilities, large surface area, and low thermal conductivity in PDP. In this regard, Aldeen et al [92], comprehensively explored the altered ZrO 2 NPs based photocatalysts for organic pollutant degradation. The typical insights of inorganic pollutant degradation, specifically the heavy metal ions present in wastewater, are missing.…”

In this study, Copper oxide/zirconium dioxide (CuO/ZrO2) nanocomposites (NCs) as a photocatalys was examined during photocatalytic degradation process (PDP) in the efficient removal of Sulfamonomethoxine (SMM) from pharmaceutical industry wastewater (PI ww) plant, İzmir, Turkey. Different pH values (3.0, 4.0, 7.0, 9.0, 10.0 and 12.0), increasing SMM concentrations (5, 10, 20 and 40 mg/l), increasing CuO/ZrO2 NCs concentrations (100, 200, 400, 800 and 1000 mg/l), different CuO/ZrO2 NCs mass ratios (1/2, 2/3, 3/4, 4/4, 4/3, 3/2, 2/1), increasing recycle times (1., 2., 3., 4., 5., 6. and 7.) was operated during PDP in the efficient removal of SMM in PI ww. The characteristics of the synthesized nanoparticles (NPs) were assessed using XRD, DRS, FESEM, EDX, FTIR, TEM and XPS analyses, respectively. The acute toxicity assays were operated with Microtox (Aliivibrio fischeri also called Vibrio fischeri) and Daphnia magna acute toxicity tests. The photocatalytic degradation mechanisms of CuO/ZrO2 NCs and the reaction kinetics of SMM were evaluated in PI ww during PDP. Cost analysis was evaluated for SMM removal with CuO/ZrO2 NCs by PDP in PI ww. ANOVA statistical analysis was used for all experimental samples. Maximum 99.6% SMM removal was obtained during PDP in PI ww, at 350 W UV-vis light irradiation power, at 147 mW/cm2 light intensity, after 120 min, at pH=12.0 and at 25oC, respectively. Maximum 99.2% SMM removal was found with PDP in PI ww, at 5 mg/l SMM, at 350 W UV-vis, at 147 mW/cm2, after 120 min, at pH=12.0 and at 25oC, respectively. Maximum 99.5% SMM removal was measured to 800 mg/l CuO/ZrO2 NCs with PDP in PI ww, at 5 mg/l SMM, at 350 W UV-vis, at 147 mW/cm2, after 120 min, at pH=12.0 and at 25oC, respectively. Maximum 99.4% SMM removal was measured at 4/3wt CuO/ZrO2 NCs mass ratios, at 5 mg/l SMM, at 800 mg/l CuO/ZrO2 NCs, at 350 W UV-vis, at 147 mW/cm2, after 120 min, at pH=12.0 and at 25oC, respectively. Maximum 99.5% SMM recovery was measured in PI ww during PDP, after 1. recycle time, at 5 mg/l SMM, at 800 mg/l CuO/ZrO2 NCs, at 4/3wt CuO/ZrO2 NCs mass rartio, at 350 W UV-vis, at 147 mW/cm2, after 120 min, at pH=12.0 and at 25oC, respectively. 97.31% maximum Microtox acute toxicity removal was found in SMM=20 mg/l after 180 min, and at 60oC. It was observed an inhibition effect of SMM=40 mg/l to Microtox after 180 min, and at 60oC. 93.27% maximum Daphnia magna acute toxicity removal was obtained in SMM=20 mg/l after 180 min, and at 60oC, respectively. It was obtained an inhibition effect of SMM=40 mg/l to Daphnia magna after 180 min and at 60oC. As a result, the CuO/ZrO2 NCs during PDP in PI ww was stable in harsh environments such as acidic, alkaline, saline and then was still effective process. Finally, the combination of a simple, easy operation preparation process, excellent performance and cost effective, makes this CuO/ZrO2 NCs a promising option during PDP in PI ww treatment.

“…However, its large bandgap of 3.87 eV and high electron-hole recombination rate makes ZrO 2 's photocatalytic activity limited to the UV range [27]. Interestingly, several recent studies have demonstrated that the combination of various other metal oxides with ZrO 2 to form a heterojunction would eventually increase its visible-light-active efficiency during the degradation process [28].…”

Antibiotic pollution beyond the safety limits poses a significant threat to the environmental sustainability and human health which necessitates the development of efficient methods for reducing antibiotics in pharmaceutical wastewater. Photocatalysis is a proven technology which has drawn considerable attention in semiconductor photocatalysts. Our study aims to develop a highly efficient Cr2O3/ZrO2 photocatalyst for the degradation of tetracycline (TCL) under visible light. The synthesized catalyst was well characterized by XRD, HR-TEM-SAED, XPS, FT-IR, BET and UV-Vis-DRS methods. The effects of various parameters on photocatalytic degradation were evaluated in detail, showing that 97.1% of 50 mgL−1 tetracycline concentrations could be degraded within 120 min at pH 5 with a 0.1 gL−1 photocatalyst-loading concentration under visible light (300 W Xe lamp). The uniform distribution of spherical ZrO2 nanoparticles on the surface of the Cr2O3 nano-cubes efficiently reduced the recombination rate with an energy bandgap of 2.75 eV, which provided a faster photodegradation of tetracycline under visible light. In addition, a plausible degradation pathway and photoproducts generated during the photocatalytic degradation of TCL are proposed based on the LC-ESI/MS results, which suggested that efficient photodegradation was achieved during the visible light irradiation. Thus, our study reveals that the cost-effective Cr2O3-based photocatalyst with multi-reusability and efficient energy consumption could be an efficient photocatalyst for the rapid degradation of TCL during the wastewater treatment process.
