Stainless Steel Pet Bowl

Material Composition Assumptions

A typical stainless steel pet bowl weighing approximately 600 grams contains the following material composition based on standard austenitic stainless steel grades commonly used for food contact applications. Iron forms the primary constituent at 420-432 grams representing the base metal structure. Chromium contributes 96-108 grams providing essential corrosion resistance properties that enable the bowl’s durability in wet environments. Nickel content ranges from 48-60 grams and enhances formability while maintaining structural integrity. Minor alloying elements including manganese, silicon, and carbon comprise the remaining 12-18 grams and serve to optimize mechanical properties and manufacturing characteristics.

Manufacturing Geography

Stainless steel pet bowls are primarily manufactured in China, which dominates global stainless steel production capacity and has established supply chains for consumer pet products. The Chinese electricity grid operates at an average carbon intensity of 555 grams of carbon dioxide equivalent per kilowatt-hour, reflecting the country’s significant reliance on coal-fired power generation. This grid intensity directly impacts the emissions associated with electric arc furnace operations used in stainless steel production. Chinese manufacturers benefit from integrated supply chains that include both raw material processing and finished product assembly, though this concentration also means that grid decarbonization efforts in China will significantly influence global emission factors for these products.

Regional Variation

Manufacturing Region	Grid Intensity (gCO2e/kWh)	Estimated CCI Score	Adjustment vs Default
China	555	32	Baseline
European Union	275	26	-19%
India	632	34	+6%
South Korea	436	29	-9%
United States	386	28	-13%

Provenance Override Guidance

1. Submit production route documentation specifying the percentage of recycled content versus primary material inputs, as scrap-based production routes demonstrate significantly lower carbon footprints than virgin material processing.

2. Provide electricity consumption data for steelmaking operations along with specific grid mix or renewable energy purchasing agreements that differ from regional average grid intensities.

3. Document specific stainless steel grade and chemical composition, as different alloy compositions require varying amounts of energy-intensive alloying elements like nickel and chromium.

4. Supply transportation logistics data including shipping distances and modes for both raw material inputs and finished product distribution to major markets.

5. Provide end-of-life recycling commitments or take-back programs that ensure high recovery rates, as stainless steel recycling significantly reduces lifecycle emissions through material loop closure.

Methodology Notes

• The CCI score represents cradle-to-gate emissions for a typical 600-gram stainless steel pet bowl including raw material extraction, processing, and manufacturing through to factory gate delivery.

• Scope 3 emissions dominate the carbon footprint due to energy-intensive mining and processing of alloying elements, particularly nickel and chromium extraction from ore sources.

• Scope 2 emissions reflect electricity consumption during electric arc furnace steelmaking operations, with significant variation possible based on regional grid mixes and renewable energy adoption.

• The functional unit assumes a single pet bowl with standard food-grade stainless steel construction suitable for typical domestic pet feeding applications.

• Excluded from this assessment are use-phase emissions, end-of-life processing, and packaging materials, though the high recyclability of stainless steel provides significant credits in cradle-to-grave analyses.

• Data gaps exist around specific manufacturing processes for forming and finishing operations, which may introduce modest uncertainty in the final emission factors.
