    Improvement in chemical vapor deposition (CVD) methods to efficiently synthesize high-quality carbon nanotubes (CNTs) is critical to commercialization of CNTs. Methods with less environmental impacts are preferable for sustainable chemistry. However, in the field of material sciences, the environmental impacts are rarely quantified. Here we provide a systematic investigation on the life cycle greenhouse gases (GHGs) emission of two emerging CNT synthesis methods: on-substrate and fluidized-bed CVD. Based on years-long experiments, we show the impacts of important configurations. We find that the life cycle GHGs of CNT production ranged from 28.55 (on-substrate) to 0.48 (fluidized-bed) kg CO2e/g CNTs. Considering the scale-up effects to industrialized levels, CNT production can be as low as to present carbon fiber (0.02 kg CO2e/g materials).

     概要を見る

    This study aims to assess the sustainability of P fertilizers consumption in a country. We has developed a Social Life Cycle Assessment (SLCA) framework to semi-quantify the "hidden" social impacts in a systematic manner. These include issues like P security of countries without the resource, human right conflicts in mining countries, etc. Our results showed that, although producing recycled-P fertilizers cost more than importing mineral-P fertilizers, social impacts in the supply chains could mostly be alleviated. A case study of Japan using the developed framework has been published in journal, Sustainability, in July 2017, “Support Phosphorus Recycling Policy with Social Life Cycle Assessment: A Case of Japan” by the researcher.
