Implementation of Green Chemistry Principles for Chemical Industries towards Sustainable Development Goals: The Use of Renewable Resources

Sustainable development goals (SDGs), the collection of 17 goals proposed by the United Nations in 2015, aimed to improve the world by tackling social, environmental and economic sustainability. Among SDGs, clean water and sanitation (SDG 6), affordable and clean energy (SDG 7), industry, innovation, and infrastructure (SDG 9), responsible consumption and production (SDG 12), and climate action (SDG 13) are related to the outcomes of impure water, clean energy, toxic chemicals, and climate change. Water scarcity affects more than 40 % of people around the world, and one in every four people would be negatively impacted by water scarcity in the future. In particular, contamination by toxic chemicals and global warming are the major contributors to global water pollution and scarcity, respectively. Therefore, green chemicals in accordance with green chemistry principles (GCP) is one of the business opportunities proposed by Business & Sustainable Development Commission in their flagship report “Better Business, Better World”. GCP are comprehensively developed and utilized in industrial management, governmental policy, educational practice and technological development around the world. To implement GCP practices into chemical industries, we proposed new categories of GCP including (1) pollution and accident prevention, (2) safety and accident assurance, and (3) energy and resource sustainability. The integration of GCP and chemical industry can be achieved by cleaner production, the continuous application of an integrated preventive environmental strategy applied to processes, products and services. This could increase the overall efficiency of energy and resources, while reducing risks to humans and the environment. We also illustrate several portfolio options of technologies for establishing waste-to-energy and –resource supply chains, such as biomass wastes utilization, towards circular economy system. Lastly, we provide several perspectives and prospects, including (1) developing green technologies for cleaner production, (2) establishing sustainable material management system, (3) building smart circular economy park, (4) promoting green economy business models, and (5) implementing multi-scale system analysis towards green engineering and sustainable technology.
