 It is argued by some more qualified than myself that because carbon is locked into the straw during its growth, that carbon is effectively "banked" thereby offsetting the carbon in the other building materials so that a strawbale building can have a  

zero or even negative carbon rating. This line of reasoning seems to me to be more valid than the "offsets" used to cancel out our extravagancies with token gestures.

   Another plus for SB: Research is now showing that because farmers are not allowed to burn off straw, and have to plough it back into the soil, this is creating a problem with soil fertility inasmuch as straw needs fungal action for it to decompose and there is now an excess of fungi building up in the soil, year by year, seriously depleting its' fertility.

  Hello,

  It's hard to make exact calcullations, because it is very complex phenomenon. But there are some approximate figures. It is called embodied energy.

  Here are the tables:

  With straw:

  Without straw:

  2007/11/2, Rikki Nitzkin <rikkinitzkin at earthlink...>: 
    I have gotten a request for exact figures on
    -how much energy is spent in producing a bale
    -how much CO2 is produced by it

    can anyone help?
