Some of the ecological challenges presented by bio-concrete production, as outlined in the paper, is the high energy needs for synthesizing urea, and effluent run off.
Other challenges stated are the corrosion of steel reinforcements from the calcium chloride. One would need corrosion resistant reinforcements.
Corrosion is a problem with conventional reinforced concrete. The other day I saw an article about an MIT prof who was making rebar with a stainless steel outer layer that holds up better.
Sounds super interesting and promising.
