Steel is the most recyled material in the world. SPX supports sustainable development - in that it meets the needs of the present without compromising the ability of future generations to meet their own needs. SPX structures are made from 95% recycled steel - the most recylced material in the world - more than all other materials combined.   Also, with no rerquired maintenance, galvanized steel has a zero-carbon footprint during its lifetime in use. 

1.  Is galvanizing sustainable?  Galvanizing, the coating of iron on steel with zinc, is probably the most environmentally friendly process available to prevent corrosion. It is estimated that corrosion costs around 4% of GDP. Effective corrosion protection is a vital means of reducing the embodied carbon of buildings and structures.

2.  Can galvanized steel be reused?  Many galvanized steel products can be removed, re-galvanized and returned to use. For example, highway guard rails are often removed and replaced during routine highway maintenance and resurfacing.  The redundant barriers are returned to the galvanizing plant for re-galvanizing and are then used again in similar applications.

3.  Can galvanized steel be recycled?  Galvanized steel can be recycled easily with other steel scrap in the electric arc furnace (EAF) steel production process.  Zinc volatillises early in the process and is collected in the EAF dust that is then recycled in specilalist facilities and often returns to refined zinc production.

4.  How much zinc is recycled from galvanized products?  In 2006, the European steel industry (EU27) produced 1,290,750 tonnes of EAF dust, which contained 296,872 tonnnes of zinc (i.e.  23%). 93% of this zinc (276,920 tonnes) was recycled. (source: Gesellschaft fur Bergbau, Metallurgie, Rohstaff - und Umwelttechnik, Germany).

5.  What is the embodied carbon of galvanized steel?  A review of available life cycle studies by Life Cycle Engineering (Torino, Italy) has indicated the typical metrics for galvanizing one kilogramme of steel to EN ISO 1461 will produce 0.1 - 0.33 kg CO2 equivalent.  The range represents variations in type of steel components, geographical factors and study methodology.

6.  What is the galvanizing industry doing to support sustainable construction? Galvanizers Association has been a major contributor to the European Initiative for Galvanizing in Sustainable Construction.  Many independent experts have contributed to this initiative including Prof. Tom Woolley, a well-known advocate of green and natural building.  The aims of the initiative were to help architects, specifiers, engineers, developers and their clients consider how to use galvanized steel in the context of sustainable construction.
