Hazardous substances
Zinc Oxide is classified under the GHS as hazardous to the aquatic environment (see safety data sheet HS-PT-00001, revision 12, 2022). The hazard relates to release into the aquatic environment, for example through spills. The product is supplied in closed big bags. Release of dangerous substances during the use stage is not assessed in this cradle-to-gate EPD.
Product description
This study evaluates the environmental performance of Zinc Oxide Maximo 955x, distributed in big bags (capacity of big bags: 1,000 kg; weight: 2.8 kg).
Zinc oxide Maximo 955x is a critical component that activates and accelerates the vulcanization process of tire manufacturing and rubber compounding. Many characteristics in rubber are attributed to Zinc oxide, such as: thermal properties, mold cleanliness and shrinkage, tire abrasion and wear resistance, ultraviolet light protection and processability.
Interpretation
Raw material supply contributes 40% to over 90% of the total impact from cradle to gate. Transportation of raw materials is around 10-15% in most impact categories. This is related to the materials with larger mass transported by truck (57% of facilities providing EAF dust in Mexico). Rail transportation impacts are lower per kgkm in comparison. The manufacturing stage is driven by energy consumption for mixing, separation, and other production stages using coal, natural gas and electricity.
LCIA results are relative expressions and do not predict impacts on category endpoints, the exceeding of thresholds, safety margins or risks. EPDs are comparable only when they follow the same PCR, functional unit and system boundary. The full EPD (PDF) contains the methodology, scenario assumptions and verification statement.
