主題
Activating Biomass to Reverse Climate Change / Retarding Global Warming through Biocarbon​
​活化生物質反轉氣候變遷 / 以生物碳減緩地球暖化

摘要

• Climate Mitigation: Goals & Objectives

          – COP21 goal for halting catastrophic rise of atmospheric CO2
          – How to restore atmospheric CO2 to safe level by year 2100

• Principal concerns of Taiwan semiconductor industry:

          – Reliable and sustainable source of electricity: thorium MSR (not here)
          – Greener source of ultrapure water for washing chips/wafers

• Carbonization of Biomass by Supertorrefaction (STR)

          – Biocarbon (bioliquids & syngas byproducts not discussed here): activated carbon, biochar, biocoal (C-neutral)
          – Large-scale usage of biocarbon, which is not burned, can give negative CO2 emission and reverse climate change before 2100
