Lignacite ECO 70 7.3N 140mm
The 140 mm depth of the ECO 70 block — at least 70% recycled and secondary aggregate. Its 17.3 kgCO₂e/m² is net of 16.3 of biogenic carbon held in the mix against 33.5 of fossil emissions, and C3 returns +13.7 of that at end of life. The 100 mm version of the same block is recorded separately and is not simply this figure scaled down.

Recorded Carbon Result
A1–A3 GWP-total per m² of 140 mm wall (216 kg), net of 16.3 kgCO2e of biogenic carbon in the mix against 33.5 of fossil emissions — a store the declaration returns as +13.7 at C3. Carbonation adds a further declared -1.89 in use (B1).
Indicator: GWP-total
Lignacite ECO 70 7.3N 140mm (HUB-2922)A1–A3 covers raw-material supply, transport to manufacture and manufacturing. It is product-stage information, not a whole-life result.
