“…Reducing the weight and the thickness of the products, designing that allows the product to be more easily recycled, changing the packaging are examples of this approach. The main point of view in the change of packaging is that the protection of the product is guaranteed by the minimum amount of packaging material [8].…”

“…However, with the developments of quality and savings the investment can be repaid in a very short-dated and with this application the company can more easily switch to more up-to-date and modern production processes. Such applications also provide improvements in product and production quality [8][9][10] . Reuse/Recycling: Reusing rinse water from one process to another cleaning process is an example of on-site recycling or reuse.…”

The public awareness and the growing perception of social cognizance about the environment have forced the textile industry to produce environmentally friendly products. For this reason, nowadays many companies and organizations focus on the environmentally friendly way of production. In order to create a sustainable textile, the main change factors have been linked to eco-materials so less and harmless waste, reusing/recycling, lesser usage of energy, water and chemicals and ethical issues in production processes. This article emphasizes the environmental effects of textiles in detail and contributes to cleaner production and sustainability in the textile industry by initiating a discussion on the opportunities for change in textile processes in accordance with the laws.

The removal of aniline blue dye from aqueous solutions using the A-site doped perovskite Ce 1−x Bi x CrO 3 (x = 0, 0.5, 1) was investigated. The perovskite oxides were synthesised using Sol-Gel method and characterised by conventional powder X-ray diffraction technique. The X-ray diffraction measurements suggested that doping with Bismuth Ion influences both the crystal structure and the particle size of the oxides, and consequently affects the adsorption properties. It was found that both CeCrO 3 and Ce 0.5 Bi 0.5 CrO 3 compounds are orthorhombic and have approximate particle size of 87 and 36 nm respectively, whereas BiCrO 3 oxide has rhombohedral space group symmetry and the particle sizes are less than 49 nm. The batch mode study demonstrated that the removal capacities of Aniline Blue at 150 min and pH = 4.3 for Ce 0.5 Bi 0.5 CrO 3 , CeCrO 3 and BiCrO 3 are 779.67, 705.45 and 440.18 mg/g respectively. The results reflect the influence of the A site doping on the adsorption properties of the oxides. The removal of Aniline Blue was found to be negatively correlated with temperature and pH.

“…However, the treatment facilities target easily biodegradable organic matter, rather than refractory non-biodegradable organic matter, as long as the facilities can comply with traditional regulations for Depending on the type of industry, some industrial discharges are abundant in NBDSCOD, and thus, more refractory in a biological treatment process. For example, it has been reported that dyeing factories discharge a large amount of NBDSCOD [4,8,9]. Because many chemical dyes are based on aromatic or heterocyclic ring structures, which are considered non-biodegradable, industrial discharge from dyeing factories likely contains substantial amounts of NBDSCOD.…”

Municipal wastewater treatment plants (WWTPs) in Korea collect and treat not only domestic wastewater, but also discharge from industrial complexes. However, some industrial discharges contain a large amount of non-biodegradable organic matter, which cannot be treated properly in a conventional biological WWTP. This study aimed to investigate the characteristics and biodegradability of the wastewater organic matter contained in the industrial discharges and to examine the fate of the industrial discharges in a biological WWTP. In contrast to most previous studies targeting a specific group of organic compounds or traditional water quality indices, such as biological oxygen demand (BOD) and chemical oxygen demand (COD), this study was purposed to quantify and characterize the biodegradable and nonbiodegradable fractions of the wastewater organic matter. Chemical oxygen demand (COD) fractionation tests and fluorescence spectroscopy revealed that the industrial discharge from dyeing or pulp mill factories contained more non-biodegradable soluble organic matter than did the domestic wastewater. Statistical analysis on the WWTPs' monitoring data indicated that the industrial discharge containing non-biodegradable soluble organic matter was not treated effectively in a biological WWTP, but was escaping from the system. Thus, industrial discharge that contained non-biodegradable soluble organic matter was a major factor in the decrease in biodegradability of the discharge, affecting the ultimate fate of wastewater organic matter in a biological WWTP. Further application of COD fractionation and fluorescence spectroscopy to wastewaters, with various industrial discharges, will help scientists and engineers to better design and operate a biological WWTP, by understanding the fate of wastewater organic matter.
