The construction industry is responsible for approximately 40% of global CO₂ emissions and generates one third of all waste in the EU. To meet climate goals, we must change how we build. LGSF (Light Gauge Steel Framing) offers a path to sustainable construction — and the numbers prove it.
Steel: The Most Recycled Material on the Planet
Steel is 100% recyclable — without any loss of quality. Unlike concrete, which degrades when recycled, or wood, which is usually burned or landfilled after its service life, steel can be recycled indefinitely.
Fact: Steel is the most recycled material worldwide. More steel is recycled than all other materials combined — including paper, glass, aluminum, and plastic.
Recyclability Comparison
| Material | Recyclability | Quality After Recycling | Typical End-of-Life Fate |
|---|---|---|---|
| Steel (LGSF) | 100 % | No loss | Recycling → new steel |
| Concrete | 20–30 % | Degraded | Crushed → road base |
| Brick | 10–20 % | Degraded | Landfill / crushing |
| Wood | 30–50 % | Degraded | Incineration / landfill |
| Aluminum | 90 % | Slight loss | Recycling |
Construction Waste: 2% vs 25%
One of the most compelling arguments for LGSF is the dramatic reduction of construction waste.
Traditional construction generates 15–25% waste of total materials. This means a quarter of purchased materials end up in landfill. With LGSF, waste is under 2% — because every profile is custom-made according to a digital model.
Bob Moore from the US company Lark Builders summed it up best: “The waste from an entire 12×24 foot steel building fits in one hand.” And for that waste — steel scrap — you even get paid because it is fully recyclable.
Carbon Footprint: Whole Life Cycle
Critics often point to the energy intensity of steel production. But looking at the entire life cycle of a building, the picture is different:
Manufacturing
- Traditional steel production (BF-BOF) has a high carbon footprint
- Modern recycled steel production (EAF — electric arc furnace) reduces emissions by 30–70 %
- ArcelorMittal XCarb™ program: steel made from recycled material with renewable energy
Construction
- LGSF: minimal waste, less transport (lighter material), shorter build time
- Concrete: huge water and cement consumption (cement production = 8% of global CO₂ emissions)
- Masonry: wet processes, high waste, long construction
Operation (50+ years)
- LGSF buildings are 5–6× more energy efficient than concrete
- Lower energy consumption for heating and cooling = lower emissions over the entire lifespan
- This is the decisive factor— operational emissions account for 60–80% of the building's total carbon footprint
End of life
- LGSF: dismantling and 100% steel recycling
- Concrete: demolition, crushing, majority to landfill
- Masonry: demolition, limited recycling
EU Green Deal and the construction sector
The European Union aims for climate neutrality by 2050. Key milestones:
- 2030: Reduction of emissions by 55%
- 2035: Reduction of emissions by 90%
- 2050: Climate neutrality
The Construction Products Regulation emphasizes the circular economy— materials must be recyclable and buildings must be designed for dismantling. LGSF naturally meets both requirements.
LEED and BREEAM certification
LGSF buildings contribute to achieving prestigious sustainability certifications:
- Recycled content— steel from EAF contains 70–90% recycled material
- Regional materials— steel is produced locally in Europe
- Construction waste— less than 2% meets the strictest requirements
- Energy efficiency— passive standard without compromise
- Design innovation— dismantlable construction for future recycling
Wood is not as green as it seems
Wood is often presented as the “greenest” building material. The reality is more complex:
- Only 36% of a felled tree ends up in the final building product (AISC)
- The rest is waste — bark, sawdust, offcuts
- Wood requires chemical treatment against insects, mold, and rot
- Wooden structures have a lifespan of 30–80 years vs. 50–100+ years for steel
- Deforestation contributes to loss of biodiversity and carbon sinks
