In 2025, Ermenegildo Zegna generated a total of 1,212metric tonnes of waste.a
Of this amount, 70.79% of Ermenegildo Zegna's total waste generated was recovered through methods such as recycling, reuse, or composting, while 29.21% was disposed of through landfilling, incineration, or combustion.a
In 2025, Ermenegildo Zegna reported a total waste generation of 1,212 metric tonnes, of which 70.79% was recovered through recycling, reuse, or composting.This moderate level of recovery indicates that Ermenegildo Zegna is taking steps toward improving its waste diversion practices, though there is still room to enhance recycling and recovery efforts.a
Since 2023, Ermenegildo Zegna's total waste generation remained relatively flat, but fell by 4.79% in 2025, which may reflect the beginning of a downward trend in material intensity or waste generation.a
Over the same period, Ermenegildo Zegna's waste recovery rate remained stable both in the long term and in 2025, suggesting limited progress, or consistent recovery performance, without major shifts in strategy.a
Overall, Ermenegildo Zegna’s waste generation and recovery data show a mixed and inconsistent trend. A deeper analysis of the company's activities, industry benchmarks, and operational changes is needed to assess its sustainability performance more precisely.
In 2025, Ermenegildo Zegna generated a total of 1,212 metric tonnes of waste.a

Since 2023, Ermenegildo Zegna's total waste generation remained largely unchanged, but decreased by 4.79% in 2025, which could signal the early stages of a reduction strategy.a
Over the same period, Ermenegildo Zegna reduced the hazardousness of its waste by 17.98%, with a further 52.74% decline in 2025, suggesting a sustained and meaningful shift toward safer waste profiles and lower environmental impact.a
Overall, Ermenegildo Zegna's waste and hazardousness trends are mixed or inconclusive. A more detailed review of its materials, industry standards, and operational changes would help clarify the net environmental impact of its waste strategy.a
In 2025, Ermenegildo Zegna reported that 9 metric tonnes of its total waste output were classified as hazardous. This represents 0.74% of its overall waste generation.a
The company treated this hazardous waste using a combination of methods.A majority (55.56%) was diverted from disposal through recovery-oriented treatments such as recycling or reuse. This suggests that Ermenegildo Zegna has established processes to reduce the environmental burden of its most harmful waste streams.a
