Environmental impact assessment on the emissions of quarry site processing of al-nawaser cement factory, nw yemen

Abstract

Al-Nawaser cement plant is processed to construct in Al-Mahweet, NW Yemen. The quarry area is composed of limestone of Amran Group as a main raw source for cement production, which is exposed in the high mountains beside the plant site. The chemical analysis of limestones shows 50.31% CaO content, with 0.71% MgO. No previous studies were published to discuss the environmental impact assessment in Al-Mahweet, in which Al-Nawaser cement plant is the first to construct in the area. This paper discusses the environmental impacts in the quarry and surrounding area assessing various pollution creates from emitted gases and dust, based on the guidelines of WHO and YEPA specifications. The paper discusses a mitigation plan for dust, gases emissions and noises during the quarrying and trucking processes, to prevent and/or minimize the pollution impacts of CO, CO2, SOx and NOx gases comes from the detonation of the raw materials, viechels and crushers with dust in the quarry site and surrounding area. This study deals with the expected pollution impacts in the quarry site created from blasting and extraction of the raw materials emitted gases and dust directly affect the villages, population, agriculture, surface and ground waters and biodiversity. Moreover, machines (shovels, primary crushers) and trucks operation add another impact source of emitted gases and noises.
