Most people see RASTRA as environmentally-friendly because we divert plastic waste from landfills - alot of waste. For an average sized 2,400 s.f. house we divert about 3,100 cubic feet of styrofoam that would never decompose in a landfill. That's pretty good. But RASTRA's biggest contribution to the environment is reducing the amount of CO2 in our atmosphere - both by reducing energy consumption and saving trees. You see, a 2,400 s.f. house requires 2.3 acres of forest to build, and as we all learned in the 6th grade, trees absorb CO2. If left to grow, these same trees would absorb 11,818 lbs of CO2 per year. So when you add this total to the amount we save in reduced energy consumption, a 2,400 s.f. RASTRA home positively contributes by 8-10 tons each and every year! That's 240-300 tons over the life of a 30-year mortgage and alot more over the life of the home itself. Now I don't know how to rank that level of performance on any 'green scale', but this is a pretty big deal in my mind.
I'm starting to sound like an infomercial - "but wait, that's not all".
Because RASTRA eliminates wood rot and has a much longer service life, it reduces landfill waste. New construction waste is also reduced. And for those living near one of our manufacturing plants, we don't use alot of fossil fuel to ship the materials. Lastly - and this is it - we only use less than 2kWh to produce one panel.
For those who include indoor air quality in your green criteria, RASTRA does not promote mold growth, allows HVAC systems to more effectively remove irritants from the air we breathe, and eliminates wood preservatives and pesticides.
I can't quite remember how well I answered the question "how green is RASTRA" during my original presentation, but I think a safe answer would be "as green as it gets".
Thanks for visiting.
