Priority survey between indicators and analytic hierarchy process analysis for green chemistry technology assessment

OBJECTIVES: This study presents the indicators and proxy variables for the quantitative assessment of green chemistry technologies and evaluates the relative importance of each assessment element by consulting experts from the fields of ecology, chemistry, safety, and public health. METHODS: The results collected were subjected to an analytic hierarchy process to obtain the weights of the indicators and the proxy variables. RESULTS: These weights may prove useful in avoiding having to resort to qualitative means in absence of weights between indicators when integrating the results of quantitative assessment by indicator. CONCLUSIONS: This study points to the limitations of current quantitative assessment techniques for green chemistry technologies and seeks to present the future direction for quantitative assessment of green chemistry technologies.

Research on the development of green chemistry technology assessment techniques: a material reutilization case

OBJECTIVES: This study presents a methodology that enables a quantitative assessment of green chemistry technologies. METHODS: The study carries out a quantitative evaluation of a particular case of material reutilization by calculating the level of "greenness" i.e., the level of compliance with the principles of green chemistry that was achieved by implementing a green chemistry technology. RESULTS: The results indicate that the greenness level was enhanced by 42% compared to the pre-improvement level, thus demonstrating the economic feasibility of green chemistry. CONCLUSIONS: The assessment technique established in this study will serve as a useful reference for setting the direction of industry-level and government-level technological R&D and for evaluating newly developed technologies, which can greatly contribute toward gaining a competitive advantage in the global market.
