While the CS/PLLA-based scaffolds showed the infiltration of trabecular bone and amounts of new tissue forming, but there were still some residual materials in the defect area.
In contrast, the CS/PLLA-based scaffolds showed the infiltration of trabecular bone and amounts of new tissue forming and the implanted materials becoming completely absorbed in some areas.

The global warming impact of the Mg production in China has been estimated close to 42 kg CO2 eq/kg Mg ingot [5], which is related largely to a high input of raw materials and a large volume of the generated solid waste, the Mg slag.
The waste Mg slag with a large volume should be recycled or re-used as constriction materials in order to decrease the global warming impact.
Congyun Huang et al. used Mg slag to replaced 20% limestone in raw materials for burning of Portland cement clinker, reporting a positive effect of the Mg slag on clinkerization [7].
Fluorite, ranging 2-3%, is often mixed in raw materials to catalyze the MgO reduction in Pidgeon process [5, 6].

But it is not very convenient in producing and using the beam slabs due to the limited space of the transferring columns, and the pedestals will be constructed in large quantities of materials, then the cost is much higher.
The width of a pedestal unit must include two production lines at least, and the space of the beams and materials to be transferred should take into account.
The width of road for transporting materials shall be determined by the construction equipment as well.

The fixation of CO2 to polymeric materials for the application in industrial field is one of the most valuable researches for the 21st century considering the environmental issues [1,2].
However, tedious procedures of DMC preparation in the conventional solvent-based ways are time-, energy- and materials-consuming.
