“…One study explored the sustainable potential use of HOFA as a natural adsorbent to remove organic and inorganic compounds from wastewater (Mofarrah et al, 2013a & b;Mofarrah & Husain, 2013). The preliminary results indicate that developed activated carbon from HOFA has potential industrial applications, especially removing heavy metals such as arsenic (As), copper (Cu), and lead (Pb) from wastewater streams.…”

Air quality deterioration in urban areas; high energy demand and consumption due to regional population growth and economic development; concerns about safe drinking water supplies due to a scarcity of fresh water; air quality deterioration, industrial pollution, waste management, and pollution in coastal areas; and subsequent stress on marine ecosystems are all major environmental challenges being faced by the Kingdom of Saudi Arabia. For effective protection of the environment, an interdisciplinary approach within a sustainable framework, which integrates human needs with economic development and environmental protection, is required. This paper presents an overview of Saudi Arabia's major environmental problems and challenges and offers opportunities to use economic growth, social equity, and protection of the environment as interrelated components. The role of active participation by governments, stakeholders, businesses, academic institutions, and individuals in the decision-making process and an inter-disciplinary research approach will be identified for each major environmental issue.

Epoxy Flooring/Oil Fly Ash as a Multifunctional Composite with Enhanced Mechanical Performance for Neutron Shielding and Chemical-Resistance Applications

et al. 2022

Heavy-oil fly ash (HOFA) is a graphitic carbon powder extracted in vast amounts as a waste material from burning crude oil in power plants. This HOFA has attractive structural properties besides its high amount of pure carbon (∼90 wt %). This powder exists in spherical, highly porous micron-sized particles, which implies its great potential as a mechanical reinforcement for different polymers. In this work, HOFA has been utilized to enhance the mechanical properties of epoxy flooring at HOFA weight fractions of 0, 1, 1.6, and 3.2 wt %. The obtained results revealed that the prepared epoxy-flooring/ HOFA composites at a HOFA content of 1.6 wt % showed significant mechanical improvements compared with the pristine polymer. The tensile strength and Young's module values were enhanced by ∼17 and 11%, respectively. Furthermore, the neutron-shielding performance was investigated. The composite with 1.6 wt % showed better neutron attenuation and lower transmittance than the pristine epoxy. The chemical resistance was also extensively studied against sodium hydroxide, nitric acid, and sulfuric acid. The changes in morphology, chemical elements, mass, volume, and molecular structures were investigated rigorously for pristine epoxy and its composite with HOFA at 1.6 wt %. After exposure to these chemicals for 21 days, the tested properties of the epoxy-flooring/HOFA composite showed better chemical resistance than that of the pristine epoxy. Where the epoxy-flooring/ HOFA composite showed a surface with low cracks and blistering, it showed lesser changes in mass and volume and fewer molecular structure changes. These results indicated that it is possible to use this multifunctional composite for several applications, including the petrochemical industry, radiation shielding, construction, and automobiles.
