Zinc Environmental Profile – Life Cycle Assessment – 2015 Update

Understanding the environmental footprint of zinc starts with documenting the resource requirements (energy and non-energy) and environmental releases associated with zinc mining and refining, but it also involves understanding the impacts and the benefits of using zinc during other stages in the product life cycle. These benefits can arise in use (extending the life of galvanized steel products) and through end-of-life recycling (by utilizing recycled zinc to create new products). This environmental profile was developed to provide updated information from the original Zinc Environmental Profile published in 2010 and life cycle data on primary zinc to stakeholders along the zinc value chain.

Zinc sheet has a number of attributes that make it desirable for use in a range of applications. It is durable; it is 100% recyclable, and for major applications such as roofing and wall claddings, the recycling rate reaches 95%. This high recycling rate significantly reduces the impacts of the production of the zinc used in zinc sheet. Zinc is also aesthetically pleasing, which means it is less likely to be replaced before needed.
