Assessment of the environmental performance of a newly developed technology of Dimethyl Carbonate (DMC) production; a Direct synthesis from CO2 and Methanol over CeO2 with 2-Cyanopyridine: Process development, simulation, optimization, and environmental impact assessment. (A member of a research group at the Chemical Systems Engineering Laboratory, Tohoku University, Japan) (Current project/2019-2020).
A chemical synthesis project that aims to develop new technology in the field of chemical engineering. It seeks to reduce CO2 emissions through the conversion of Dimethyl Carbonate from CO2 by utilizing captured CO2 emissions and converting them to useful chemical products in the form of DMC. My contribution to the project include (1) model and simulate the chemical processes, (2) assess and evaluate the environmental impacts of the technology, (3) chemical process optimization, (4) identify the environmental hotspots of the new technology (5) evaluate the Japan Electricity Grid Mix as a source of energy from both renewable and non-renewable energy resources for power supply to the technology, and (6) perform what-if analyses.
Resource Efficiency and Circular Economy
The concept of the circular economy (CE) is a trending topic, and it has been a proliferation of scholars, practitioners, industry, and policymakers. CE aims to overcome the prevalent take-make-use-dispose linear pattern of production and consumption. A circular pattern put back the value of resources and materials, utilizing them in the economy as long as possible; advocating reduced primary resources extraction in favor of secondary ones. This project explores three major concepts of CE: the economic, environmental, and social aspects and synthesizing the relationship between them. It aims to (1) review and classify the CE aspects and key concepts in the literature through Qualitative Data Analysis (QDA) of the articles published on CE, including the various CE definitions; and (2) classify and propose C E indicators to measure how close or far countries and industries are from the transition to CE.
Urban Environmental Resource Management
Waste management in developing countries is a research project aims to discuss, evaluate, and propose integrated solutions to waste management in developing countries. The project mainly focuses mainly on the Middle East and North Africa (MENA) region. The findings of this project should provide a scientific baseline and a reference to waste satiation in those countries. Waste types of focus are municipal and e-waste. The project is part of the major interests of the author in which it concentrates on the environmental impacts and systematic solutions founded on the integrative and life-cycle thinking approaches. Latest findings whenever available will be published as in international journals. Technical reports might also be available. Ultimately, the project should assist in mitigating the environmental impacts and to provide appropriate solutions to address the practices of the improper waste management that are based on the informal collection, informal recycling, open dumping, open burning, and unsanitary (uncontrolled landfilling).
This research focuses primarily on the environmental impacts of Waste Electrical and Electronic Equipment (WEEE; e-waste) in both developing and developed countries. In the case of developing countries, it estimates emissions their impacts on human health, environment, and ecosystems due to the poor practices as seen in several countries of the treatment and disposal of WEEE; in addition to examining the estimated inventories of emission, particularly toxic metals. The scope of this project considers both the traditional approaches to WEEE handling and state-of-the-art technologies. Environmental assessment through life-cycle thinking, material, and substance flow analysis are studied. The project also aims to develop approaches for proper WEEE handling, resource conservation, cleaner production, and approaches to positive impacts on the economy.
Metals Production (Rare Earth Metals, Precious Metals, and Base Metals)
The goal of this research is to build environmental profiles for metals production from cradle to gate. The primary focus on metals is precious and rare earth metals. The result of this research might aid to decrease their environmental impacts, lead to better cleaner production, and enhancements of production technologies. It offers a scientific baseline on their discharges to air, soil, and water as well their contribution to environmental problems such as acidification, human toxicity, freshwater aquatic system, and climate change.
