Staples (box of 5000)

Material Composition Assumptions

A typical box of 5000 standard office staples consists primarily of galvanized steel wire formed through industrial stamping processes. The total weight of the staple contents approximates 125 grams, representing nearly 100% steel composition with minimal protective coating materials. Each individual staple weighs approximately 0.025 grams and measures standard dimensions for compatibility with commercial staplers. The manufacturing process involves drawing steel wire to precise specifications, cutting to length, and forming the characteristic crown and leg configuration through automated machinery.

Manufacturing Geography

Primary production of office staples occurs in China, where extensive metalworking infrastructure and automated manufacturing capabilities support high-volume production at competitive costs. The Chinese electrical grid operates at an average carbon intensity of 555 grams of carbon dioxide equivalent per kilowatt-hour, reflecting the country’s mixed energy portfolio of coal, natural gas, and renewable sources. This manufacturing concentration results from established supply chains for steel processing, specialized tooling availability, and proximity to global distribution networks serving office supply markets worldwide.

Provenance Override Guidance

1. Submit comprehensive life cycle assessment data covering raw material extraction, steel production, wire drawing, and staple forming processes with third-party verification
2. Provide detailed energy consumption records for manufacturing facilities including electricity usage, fuel consumption, and process-specific energy requirements per unit produced
3. Document transportation emissions from steel suppliers to manufacturing facilities and from production sites to distribution centers with carrier-specific fuel efficiency data
4. Supply material composition certificates specifying steel grade, coating materials, and any recycled content percentages with supporting chain of custody documentation
5. Submit facility-specific emissions data including scope 1 direct emissions from on-site fuel combustion and scope 2 emissions from purchased electricity with regional grid factor validation

Methodology Notes

• The current CCI score reflects incomplete data availability for office staple products due to limited published life cycle assessment studies covering small metal office supplies
• Scope breakdown cannot be determined without comprehensive manufacturing process data spanning raw material extraction through finished product packaging
• The functional unit represents one complete box containing 5000 individual staples as typically sold in commercial office supply channels
• Excluded emissions categories include end-of-life disposal, consumer transportation, and stapler equipment manufacturing required for product utilization
• Significant data gaps exist regarding steel production impacts, coating process emissions, and packaging material contributions to overall carbon footprint
