Clamshell
composed mainly 95–99% (by weight) of CaCO3, the waste clamshell
is potentially convert to calcium oxide (CaO) for many application
such as filtration media/toxic-waste remediation agent/
adsorbent [2], additive of refractory [3], doped material to modify
electrical and optical (dielectric) properties [4], flue gas desulfurization
and pollutant emission control [5], construction material
[6] and solid base catalyst [7]
