Strocks Unfired Earth Block

Unfired earth blocks — clay-rich earth with chopped straw, pressed and air dried, never taken near a kiln. Firing is where essentially all of a brick’s carbon lives, so removing it changes the arithmetic entirely: the declaration reads −15.4 kgCO₂e per tonne at A1–A3, and even counting the straw carbon back at end of life the whole-life figure is +53.2, about a fifth of the same firm’s fired handmade brick. Used as the inner skin of an external wall, for internal load-bearing walls up to three storeys, and as a structural base to earth floors — not as an external facing brick. Strockettes are a smaller block from the same range, made for repairs to earthen buildings.
