Corporate Social Responsibility (CSR) has been an articulated practice for over 7 decades. Still, most corporations lack integrated framework to develop a strategic, balanced, and effective approach achieving excellence in CSR. Considering the world’s critical situation during COVID-19 pandemic, such is even more crucial now. We suggest subsuming CRS categories under Sustainable Development Goals (SDGs) be used that they subsume CSR since SDGs are comprehensive agenda designed whole planet....

Globally, petroleum has been the largest source of energy consumption compared to other sources such as natural gas and coal. As a result high demand for an source, contamination takes place due maintenance, production, exploration, storage, transportation accidental release, yielding in substantial ecological impacts. The contaminations presence soil have negative impact on human health development plant growth. According this, there is imperative need investigate environmental-friendly...

Abstract When pollutants like petroleum hydrocarbons as one of the major origins aquatic pollution, enter environment, they alter biological and/or physicochemical characteristics aforementioned sites due to their potential bioaccumulation, biomagnification, and resistance against biodegradation besides its toxicity carcinogenicity in nature. Thus, importance degradation, deterioration remediation these from environments such via a green method bioremediation is undeniable. Biosurfactants...

Different physical, chemical, and biological treatment methods are used to eliminate heavy metals pollutants from wastewater landfill leachate. Sequencing batch reactor (SBR) is a type of treatment. This study was conducted elimination urban leachate using an adsorbent, namely powdered ZELIAC (PZ) that improved SBR. PZ consists portland cement, limestone, rice husk ash, activated carbon, zeolite. Response surface methodology central composite design were elucidate the nature response in...

The effectiveness of southern cattail (Typha domingensis) for phytoremediation heavy metals from municipal waste leachate was investigated. Some plants were transplanted into pots containing 10 liters mixed urban and water (3/1 V: V) aerated during experiments. Central composite design (CCD) response surface methodology (RSM) used in order to clarify the nature experimental explain optimal conditions independent variables. In optimum conditions, amount removed Pb, Ni Cd 0.9725, 0.4681,...

Antibiotics are frequently applied to treat bacterial infections in humans and animals. However, most consumed antibiotics excreted into wastewater as metabolites or their original form. Therefore, removal of from aquatic environments is high research interest. In this study, we investigated the sulfamethoxazole (SMX) ofloxacin (OFX) with Chaetoceros muelleri, a marine diatom. The optimization process was conducted using response surface methodology (RSM) two independent parameters, i.e.,...

Advanced Oxidation Processes (AOPs) have been employed to degrade biorefractory organic matters. This study investigates the combination of classical Fenton reaction with electrochemical oxidation, electro-Fenton process, for treatment semi aerobic landfill leachate, collected from Pulau Burung Landfill Site (PBLS), Penang, Malaysia. The investigation has carried out in batch reactors aluminum electrodes establish optimal conditions. effects applied current, pH, time, separation distance,...

Biodiesel as a renewable fuel is made from materials such animal fats, plant oils, and can be used in compression ignition (diesel) engines by mixing with conventional diesel. Recently, nanocatalysts are being to generate biodiesel, they able make these reactions more sufficient having large surface-to-volume ratio. TiO2 ZnO nanoparticles categorized metal oxide nanoparticles. Each of them has its own special characteristics. Besides, show level cooperation which discussed below. In this...

Abstract A novel strategy of using microalgae Chlorella vulgaris for simultaneous bio-treatment petrochemical wastewater and lipid production was developed in the present study. Phycoremediation carried out 30 days. The profile fatty acids identified, specifications biodiesel including saponification value, iodine cetane number, long-chain saturated factor, cold filter plugging point, cloud allylic position equivalent bis-allylic were predicted by BiodieselAnalyzer® software. Besides,...
