Preliminary assessment of indoor industrial noise pollution in Kuwait

Sound is considered as a pollutant when it exceeds undesirable limits for the recipient. One of the significant environmental problems associated with industries is noise pollution generated by machinery. The main objectives of this study were to measure noise levels generated by machinery that the workers were exposed to at five industrial facilities in the State of Kuwait. Also, to assess if these levels were within acceptable standards, for Kuwait lacks environmental standards for such a pollutant. To achieve the objectives of the study two food manufacturing companies, a cement-brick making plant, a furniture factory and a car washing facility were selected for the purpose of the research.The study showed that workers operating machinery at the five facilities were exposed to high noise levels without any kind of ear protection. Noise levels recorded during the study were very high and exceeded the British Noise at Work Regulations of 1989. In Kuwait there are no regulations to abate noise in the working environment and workers are not required to wear ear protective muffs. The results of the study indicate that, the concerned environmental and health organisations in Kuwait should be compelled to establish noise level standards and controls to safeguard the health of workers and the public at large.     

Property-performance relationship of core-shell structured black TiO2 photocatalyst for environmental remediation

● Properties and performance relationship of CSBT photocatalyst were investigated. ● Properties of CSBT were controlled by simply manipulating glycerol content. ● Performance was linked to semiconducting and physicochemical properties. ● CSBT (W:G ratio 9:1) had better performance with lower energy consumption. ● Phenols were reduced by 48.30% at a cost of $2.4127 per unit volume of effluent. Understanding the relationship between the properties and performance of black titanium dioxide with core-shell structure (CSBT) for environmental remediation is crucial for improving its prospects in practical applications. In this study, CSBT was synthesized using a glycerol-assisted sol-gel approach. The effect of different water-to-glycerol ratios (W:G = 1:0, 9:1, 2:1, and 1:1) on the semiconducting and physicochemical properties of CSBT was investigated. The effectiveness of CSBT in removing phenolic compounds (PHCs) from real agro-industrial wastewater was studied. The CSBT synthesized with a W:G ratio of 9:1 has optimized properties for enhanced removal of PHCs. It has a distinct core-shell structure and an appropriate amount of Ti³⁺ cations (11.18%), which play a crucial role in enhancing the performance of CSBT. When exposed to visible light, the CSBT performed better: 48.30% of PHCs were removed after 180 min, compared to only 21.95% for TiO₂ without core-shell structure. The CSBT consumed only 45.5235 kWh/m³ of electrical energy per order of magnitude and cost $2.4127 per unit volume of treated agro-industrial wastewater. Under the conditions tested, the CSBT demonstrated exceptional stability and reusability. The CSBT showed promising results in the treatment of phenols-containing agro-industrial wastewater.

Reverse logistics in the Chinese auto-parts firms: implementation framework development through multiple case studies

In recent years, the implementation of reverse logistics (RL) in automobile manufacturing has drawn extensive interest from the Chinese government that has launched relevant take-back and environmental regulations and pilot projects. This study focuses on RL implementation issues in Chinese auto-parts manufacturing sector. Based on comprehensive literature review and multiple case studies in the Chinese auto-parts firms, this paper proposes a conceptual RL framework and highlights the major implementation issues. The purpose of this paper is to draw an overall picture of RL in the Chinese context, highlighting implementation issues in the auto-parts sector. Our study suggests that Chinese RL implementation requires close government monitoring mechanism and incentives, top management commitment within firms, technology and human capabilities support.

Characterization and adsorption capacity of modified 3D porous aerogel from grapefruit peels for removal of oils and organic solvents

With the rapid industrialization, especially offshore oil exploitation, frequent leakage incidents of oils/organic solvents have adversely affected ecological systems and environmental resources. Therefore, great interest has been shown in developing new materials to eliminate these organic pollutants, which have become worldwide problems. In this study, a cost-effective, environmentally friendly porous aerogel with three-dimensional (3D) structure was prepared from grapefruit peel by a facile hydrothermal method as the adsorbent of oils/organic solvents. The as-prepared modified grapefruit peel aerogel (M-GPA) showed mesoporous structure with high specific surface area of 36.42 m²/g and large pore volume of 0.0371 cm³/g. The excellent hydrophobicity of M-GPA with a water contact angle of 141.2° indicated a strong potential for adsorption of oils and organic solvents. The high adsorption capacity of M-GPA for a series of oils and organic solvents was 8 to 52 times as much as its own weight. Moreover, the M-GPA was easily regenerated and a high adsorption capacity recovery above 97% was maintained after five adsorption–regeneration cycles. Therefore, the M-GPA is a promising recyclable adsorbent for the removal of oils/organic solvents from polluted water.
