Sustainable options for kitchen and bath designs are available even if you were originally looking for a style made from the commonly used portland cement. Portland cement is of course, the traditional formulated concrete for pre-cast products, and is also a great contributor to greenhouse gas emissions.
Vitrastone, is a sustainable manufacturer of counters, sinks and 'vessel bowls', which are your bathroom sink/countertop styles. Vitrastone 'defines a new concrete category- they call, MPRG concrete. The name is derivitive from it's components. 'Mag Phos' cement the mp, and recycled glass, the rg. Mag Phos cements are cold fired'. www.vitrastone.com
Vitrastone takes 'substantially less energy to produce' It expands and contracts less so it doesn't easily crack. Other eco-advantages of Vitrostone also mentioned on their web-site is their use of 'regionally sourced, post-consumer and post-industrial recycled glass.' But most of the difference is in the binders used. Vitrostone uses a 'variety of cellulose materials'. This makes the biggest difference because with indoor products you are looking to avoid any off-gas fumes. There are more details on their awesome web-site, www.vitrastone.com.
All this and a five year warranty!
