Life cycle assessment

Life cycle assessment (LCA) of the production and distribution of one tonne of Zamak ingot

An exemplary low carbon footprint for recycled Zamak

Genlis Metal has confirmed its commitment to sustainable development by carrying out a rigorous life cycle assessment (LCA) of our recycled Zamak.

We assessed the environmental impact of producing and distributing one tonne of Zamak ingots, taking into account the various emissions and resource flows involved at each stage of their life cycle. Using products from the circular economy, such as by-products from foundries and various industries, as well as end-of-life parts, and drawing on a robust carbon footprint assessment, this study aimed to provide our customers with a clear, accurate statement on our environmental impact, in collaboration with IZA.

With a carbon footprint of 552.72 kg CO2 eq for Zamak 5 (Cradle-to-Gate in 2024), our data shows a strong environmental performance, especially when compared with often higher generic values.

The numbers speak for themselves

•    85% reduction in CO2 emissions compared with primary Zamak
•    84% more recyclable, ensuring a closed loop
•    0% loss in quality: recycled Zamak offers the same consistency and reliability as the primary product.

These results show that Genlis Metal’s recycled Zamak combines technical performance with environmental benefits. This means foundries can support their customers with a safe, sustainable and economical material, perfectly suited to large production runs and precision requirements.
