Evaluation of Environmental Requirements for Sustainable Ready-Mix Concrete Production in Abu Dhabi Emirate

Abstract

Sustainability is the main concern for current and future construction projects in the world. In any project, attaining sustainability requires the integrity of four main elements. These elements cover economical, societal, cultural, and environmental aspects to its successful implementation and integration in an anthropogenic framework. Concrete is one of the main building materials used in current construction activities around the world; therefore, many issues pertaining to concrete long term sustainability arise. This makes issues related to environmental evaluation and assessment for the ready-mix concrete production process of vital importance. The release of particulate matter (PM) including PM10 and PM2.5 could be considered the main air pollutant that is emitted from this industrial sector; where PM can be released from different stages of ready-mix concrete production process. Another concern arising from the ready-mix concrete operations which may affect the soil and ground water quality is the spills or leaks that may occur from the storage containers used for diesel, motor oil, and chemical admixture. In 2010, Environmental Agency-Abu Dhabi (EAD) collected data pertaining to the operations of 73 ready-mix concrete facilities in the Emirate of Abu Dhabi. The data showed that the average production rate of concrete is around 250,000 m 3 /year, which indicates that the concrete industry is a very active industry in the Emirate. Hence, EAD has established a set of plans and requirements to minimize the environmental impacts of concrete production on the environment and public health. The environmental impact of the concrete manufacturing can be reduced by conserving use of raw material ingredients, conserving energy consumption, and following Best Management Practices (BMPs) related to readymix concrete production. In this paper, a variety of BMPs are presented for ready-mix concrete manufacturing facilities in Abu Dhabi. These BMPs cover the following areas: raw materials handling and transport, process operation, housekeeping, waste management, emergency response, G. Kashwani et al. 334 and training record. EAD can then regulate the ready-mix concrete manufacturing sector in Abu Dhabi using these BMPs and the requirements of the issued permitting conditions in order to have a sustainable industrial sector.

“…Salah satu tindakan yang dilakukan untuk mendukung komitmen pemerintah Indonesia adalah tumbuhnya industri hijau. Dampak lingkungan dari pembuatan beton dapat dikurangi dengan menghemat penggunaan bahan baku, menghemat konsumsi energi, dan mengikuti Praktik Manajemen Terbaik (BMP) terkait dengan produksi beton siap pakai [1].…”

Oportunidades de reducción de impactos ambientales de la producción de hormigón en Panamá

“…Esta oportunidad contribuiría a minimizar las cantidades de polvo emitidas durante estos procesos. La reducción de estas alturas podría implementarse en el lugar de la recepción de materia prima, pesaje o dosificación de las materias primas para la producción de hormigón (Kashwani et al, 2014).…”

Application of Green Retrofitting Ready Mix Concrete Plant in Indonesia to Increase Financial Benefits and Reduce Environmental Issues: A Case Study

“…In the composition of perm3 concrete products, a material ratio of 7-15% water is required, cement 15-20%, fine aggregate 25-30%, and coarse aggregate 30-50%. The environmental impact of concrete manufacturing can be lowered by reducing the use of raw materials, reducing energy consumption, and following Best Management Practices (BMP) related to ready-mix concrete production (Kashwani, Sajwani, Ashram, & Yaaqoubi, 2014).…”
