Product catalog summary

General Information
NedZink B.V. produces pre-weathered titanium zinc products, NedZink® NOVA and NedZink® NOIR, with an Environmental Product Declaration (EPD) based on ISO 14025 and EN 15804 standards, valid from October 23, 2015, to October 22, 2020. The Life Cycle Assessment (LCA) includes the manufacturing phase, covering raw material production, transport, and packaging, with recycling credits.

Product Description
NedZink® NOVA and NOIR are high-purity titanium zinc products with added copper, titanium, and aluminum. NOVA is medium gray, and NOIR is anthracite black, used for roofing, façade cladding, and rainwater systems, suitable for indoor and outdoor applications without harmful emissions.

Technical Data
Key properties include a thermal expansion coefficient of 22 x 10^-6K^-1, tensile strength ≥ 150 N/mm², and a melting point of 420°C, complying with EN 988 standards.

Manufacturing Process
The process involves pre-alloying, melting, casting, rolling, and pre-weathering, with rigorous quality control adhering to ISO 9001 and ISO 14001 standards.

Environmental and Health Aspects
The products develop a protective patina, reducing zinc ion transfer. Zinc is essential and non-accumulative in the body, posing no health risks when used as intended. The service life exceeds 100 years under proper conditions.

Recycling and Disposal
NedZink products are highly recyclable, with a recycling rate over 90%, eliminating the need for zinc disposal.

LCA Calculation Rules
The declared unit is 1 kg of product, with a cradle-to-gate system boundary. Background data is sourced from the Ecoinvent database, with no allocation applied.

Life Cycle Assessment (LCA) Results
The LCA includes the product stage but excludes construction, use, and end-of-life stages. Key impacts per kilogram include a global warming potential of 2.09 kg CO2-Eq, with significant recycling credits in module D.

Environmental Impact
Special High Grade (SHG) Zinc production is a major contributor to environmental impacts, accounting for 53% of the global warming potential. Ozone layer depletion and acidification potentials are also heavily influenced by SHG Zinc, with contributions of 73% and 86%, respectively.

Resource Use
Details on renewable and non-renewable energy usage are provided, with significant non-renewable energy consumption during production. Fresh water net consumption is 2.26 m³.

Output Flows and Waste Categories
Hazardous and non-hazardous waste disposal is quantified, with 0.9 kg of materials available for recycling per kilogram of product.

Interpretation
The LCA interpretation highlights the dominance of SHG Zinc in various impact categories and the benefits of recycling, which significantly offset initial environmental impacts.

Requisite Evidence
Studies on zinc corrosion and run-off rates are referenced, indicating atmospheric conditions, particularly SO2 concentration, influence these rates.

References
The document cites various standards and studies, including ISO 14025, EN 15804, and several product category rules and environmental management standards.

The zinc is cast into blocks, cooled down and stored for further processing. Rolling and coiling: Blocks coming from the casting installation are homogeneous pre-heated for the “hot rolling” process. This takes place in a gas-fired continuous oven....

Impact categories for 1 kg of Nova/Noir pre-weathered zinc Life cycle inventory data for the production of zinc concentrate and SHG Zinc was adapted to the specific situation of NedZink and its SHG supplier, using the Dutch energy mix. (see also 3.5 Background Data) The contribution of Special High Grade Zinc (SHG Zinc) is the dominating factor in the GWP (Global Warming Potential) with a 53% contribution. The remaining 47% mainly consists of hazardous waste disposal (landfill) and energy usage (electricity and gas). The chemicals used during pre-weathering also have a small contribution (as...
