Broom (plastic/natural)

Material Composition Assumptions

This assessment assumes a standard household broom weighing approximately 400 grams. The bristle component comprises the largest portion at 240-300 grams of polypropylene or nylon fibers, representing sixty to seventy-five percent of total weight. The handle section accounts for 80-120 grams of wooden or bamboo material, making up twenty to thirty percent of the product mass.

Metal binding components including ferrules and wire fasteners contribute 12-20 grams or three to five percent of total weight. Packaging materials such as cardboard sleeves or plastic wrapping add 8-16 grams, representing two to four percent of the final product mass.

Manufacturing Geography

China serves as the dominant manufacturing region for household brooms, benefiting from established plastic processing infrastructure and lower labor costs. The country’s electrical grid operates at 555 grams of carbon dioxide equivalent per kilowatt-hour, which influences the carbon intensity of manufacturing operations.

Chinese facilities leverage economies of scale in both synthetic bristle production and wooden handle processing. The concentration of suppliers within industrial zones reduces transportation costs between component manufacturers and final assembly operations.

Regional Variation

Manufacturing Region	Grid Intensity	Estimated CCI Score	Adjustment vs Default
China	555 gCO2/kWh	2.8	Baseline
India	708 gCO2/kWh	3.1	+11%
Germany	366 gCO2/kWh	2.3	-18%
United States	386 gCO2/kWh	2.4	-14%
Mexico	458 gCO2/kWh	2.6	-7%

Provenance Override Guidance

1. Submit detailed material composition data showing actual weights and types of bristle materials, handle composition, and metal components used in production.

2. Provide manufacturing facility energy consumption records including electricity usage per unit produced and any renewable energy sources utilized.

3. Document transportation distances and shipping methods from raw material suppliers to manufacturing facilities and from factories to distribution centers.

4. Supply bristle material production data including polymer processing energy requirements and any recycled content percentages in synthetic components.

5. Include facility-specific emissions data covering direct manufacturing processes, waste treatment systems, and any on-site energy generation capabilities.

Methodology Notes

• The CCI score represents cradle-to-gate emissions including raw material extraction, processing, manufacturing, and packaging but excludes end-of-life disposal impacts.

• Scope 3 emissions dominate the footprint at eighty percent, primarily driven by upstream polymer production and raw material processing activities.

• The functional unit assumes one standard household broom with typical bristle density and handle length suitable for residential cleaning applications.

• Assessment excludes retailer operations, consumer use phase impacts, and end-of-life treatment processes including landfill decomposition or recycling.

• Data gaps exist regarding regional variations in wooden handle sourcing and the carbon impacts of different bristle manufacturing techniques across suppliers.
