Speech Title and Abstract

Integrated and Innovative Solutions on Net-Zero Circular Economy for High-Tech Facilities

Recently, with the rapid development of the global economy and the acceleration of industrialization, and large-scale deforestation have led to increased global warming which caused the negative externalities and spillover effects around the world. Both scientists and engineers have to find cost-effective carbon reduction strategies and technologies for high-tech factories.

For instance, construction of Net Zero circular economy strategies should be focused on governance and road maps, integration of energy and resources, circular technology and materials innovation, TCFD related financial disclosures and carbon border tax and sustainable finance. Development of digital transformation program should be investigated on digital technologies (blockchain, IoT, automation, and AI), data-driven decision-making and system integration, sustainability-minded innovation, leveraging digital technologies and collaborative and decentralized business models. Establishment of sustainable supply chain management should be emphasized on circular supply chain design and optimization, sustainable procurement and supplier management, logistics and transportation management, measuring and reporting on circularity and evaluating the economic and environmental benefits.

In general, the design efficiency could be improved by atom economy, catalysis, use of renewable feedstocks, and real-time pollution prevention. Energy efficiency could be enhanced by introducing best available technology with higher thermal and electrical efficiencies. Fuel switching by utilizing alternative fuels, waste fuels, hydrogen, biomass, and renewable energy. Carbon capture utilization and storage (CCUS) technologies including pre-combustion, oxy-fuel, post-combustion, direct separation, and carbon utilization can be employed to reduce the carbon emissions.

Among them, the natural mechanism of natural carbon sinks has attracted much attention as an economical means of reducing atmospheric CO2 concentrations. As a result, this paper was focused on investigating principles of natural carbon sink, natural carbon sink measurements, enhancement of the natural carbon sink, and biomass energy utilization technologies for achieving sustainable management of nature and increasing natural carbon stocks.

Finally, the integrated and innovative solution, i.e. Green solution, should be developed and based on implementing Green Chemistry Principles for Carbon Neutrality, Establishing Carbon Neutral Management for Circular Economy, Strengthening Sustainable Consumption and Production for Circular Economy, Development of Energy and material Efficient Technologies for Green Industry, and Use of IoT for Industry 4.0 and Sustainability.
