1. A method for producing a formed building material comprising:
- a) contacting a gaseous waste stream comprising a CO2 with water comprising proton removing agent to form a CO2 charged water;
b) producing a CO2-sequestering component from a saltwater solution of divalent cations and the CO2 charged water under one or more of precipitation conditions favoring precipitation of the CO2-sequestering component comprising a metastable carbonate comprising amorphous calcium carbonate, vaterite, aragonite, or combinations thereof; and
c) forming the formed building material from the CO2-sequestering component in a process comprising contacting the CO2-sequestering component with water, wherein the formed building material is selected from the group consisting ofa) a brick having a compressive strength ranging from 5 to 100 MPa;
b) a block having a compressive strength ranging from 5 to 100 MPa;
c) a tile having a compressive strength ranging from 5 to 75 MPa;
d) a cement board having a compressive strength ranging from 5 to 50 MPa;
e) a drywall having a compressive strength ranging from 1 to 20 MPa;
f) a conduit having a compressive strength ranging from 5 to 75 MPa;
g) a beams having a compressive strength ranging from 35 to 150 MPa;
h) a basin having a compressive strength ranging from 5 to 60 MPa;
i) a column having a compressive strength ranging from 25 to 200 MPa;
j) a fiber-cement siding having a compressive strength ranging from 2 to 25 MPa;
k) a slab having a compressive strength ranging from 10 to 100 MPa;
l) acoustic barrier of at least 0.5 m in length; and
m) insulation material.
