The environmental sustainability of SPC flooring is generally considered to be good. SPC stands for Stone Plastic Composite, and it is made from a combination of natural limestone powder, polyvinyl chloride (PVC) resin, and stabilizers.

SPC Rigid Core Flooring is free from harmful substances such as formaldehyde and heavy metals, which makes it a safe choice for indoor environments. Additionally, SPC flooring is recyclable and can be reused in the production of new flooring materials.

Moreover, SPC Vinyl Plank flooring does not require the use of adhesives during installation, as it has a click-lock system that allows the planks to be easily snapped together. This reduces the emission of volatile organic compounds (VOCs) and contributes to better indoor air quality.

It's worth noting that the overall environmental impact of SPC flooring also depends on factors such as the sourcing of raw materials and the manufacturing processes used by different brands. Hence, it's advisable to look for flooring products that are certified as environmentally friendly by recognized organizations, such as those meeting the standards set by the FloorScore or GREENGUARD programs.
