Development of technology for recycling woody biomass ash that fixes CO2 (BECCS-ASH®)
Abstract
The authors are developing BECCS (Bio-Energy with Carbon Capture and Storage) technology that storesCO䈻 in green areas by fixing CO䈻 derived from woody biomass power generation in woody biomass ash andrecycling the ash as greening materials. This report focuses on the bottom ash of woody biomass ash, and we
examined the effect of carbonation on the elution characteristics of the bottom ash, the amount of CO₂
absorption, the physical properties of greening materials prepared by kneading purified water-generated soil
as secondary materials, environmental safety, and effects on plant growth.
In the elution test of carbonated woody biomass ash, the carbonation treatment showed a decrease in pH
and a decrease in Pb, Cr(VI), and F, while an increase in elution of As and B was observed. The amount of
CO₂ absorbed by BECCS-ASH was 5-24 g-CO₂/kgDW-ash, which was similar to previous reports of MSW
bottom ash. The greening material satisfied soil environmental standards, and pH, EC, saturated hydraulicconductivity, and available moisture also met the criteria for the performance of artificial soil. In addition,
the results of the plant damage test suggested that the effect on the germination and growth of Komatsuna(Brassica campestris) was small, and that BECCS-ASH could be used as a greening material capable ofcarbon storage.
