Of the total energy consumed by our facilities worldwide in fiscal 2023, 43.3% was derived from renewable sources. The renewable sources include (i) wind and solar electricity consumed at our facility in Heinsberg, Germany (1.1% of total energy consumed) and (ii) heat from the burning of hardwood sawdust at four locations in our Quanex Custom Components business (38.8% of total energy consumed).
Water Usage (M3)

| European Fenestration | 8,495 | 9,815 |
| Corporation Total | 321,817 | 304,960 |
This figure represents the total water usage across all our manufacturing operations around the world. Quanex is keenly aware that water is a precious resource, and our teams strive to reduce water consumption through continuous improvement activities.

| North American Fenestration | 45,218,479 | 38,751,007 |
| Quanex Custom Components | 11,921,690 | 12,348,001 |
| European Fenestration | 9,947,239 | 8,567,077 |
| Corporation Total | 67,087,408 | 59,666,085 |
This figure represents the consumption of natural gas from all Quanex manufacturing locations around the world.
WASTE GENERATION
Hazardous Waste (mt)
| Divisions | FY2022 | FY2023 |
| North American Fenestration | 8.2 | 9.6 |
| Quanex Custom Components | 0 | 0.0 |
| European Fenestration | 82.1 | 82.1 |
| Corporation Total | 90.3 | 91.7 |
In considering our hazardous waste generation, we found that contradictory definitions of “hazardous waste” presented by various jurisdictions presented a roadblock to our ability to disclose a single worldwide metric. In Germany, for example, the legal definition of “hazardous waste” includes a certain process wastewater that does not qualify as hazardous within the United States or United Kingdom. The United Kingdom likewise has a more stringent hazardous waste definition than does the United States, though not as stringent as Germany. As such, it is important to view each of the fiscal year figures disclosed within the proper context by considering the conflicting legal definitions that drive each jurisdiction’s definition of “hazardous waste.”
Non-Hazardous Waste (mt)
| Divisions | FY2022 | FY2023 |
| North American Fenestration | NA | 9,579,447 |
| Quanex Custom Components | NA | 1,350,192 |
| European Fenestration | NA | 1,011,884 |
| Corporation Total | NA | 11,941,523 |

tCO2e = Metric Tons of CO2 equivalent
