I am an engineer for a green start-up company that manufactures durable surfaces made of recycled glass and portland cement. We typically fall underneath the "decorative kitchen counterop" category of this industry. We are now in a new stage of innovation and, in keeping with our mission, we are trying to keep as environmentally friendly and conscience as possible.
Are any of you aware of any new green additives or binders that could be used for the sustainablity of concrete? I know hot buzz words are "biopolymers" and "bioresins", but are they really, well...green?
Thank you so much,
