Plastic Storage Bin

Material Composition Assumptions

A typical plastic storage bin consists primarily of polypropylene resin, which makes up approximately 95% of the total product weight. For a standard 1.5 kilogram storage container, this translates to roughly 1,425 grams of polypropylene material. The remaining 5% consists of colorants, UV stabilizers, and processing additives that enhance durability and appearance, totaling approximately 75 grams. Virgin polypropylene derived from crude oil refining represents the dominant material input, though some manufacturers incorporate recycled polypropylene content to reduce environmental impact. The polymer structure provides the necessary strength and flexibility characteristics required for repeated use cycles.

Manufacturing Geography

Plastic storage bins are predominantly manufactured in Asia, with China, India, and Southeast Asian countries serving as major production hubs. These regions benefit from established petrochemical infrastructure, proximity to raw material sources, and cost-effective labor markets. The manufacturing process occurs in facilities that typically rely on regional electrical grids with carbon intensities ranging from 400 to 800 kgCO2e per megawatt-hour. China’s national grid intensity averages approximately 650 kgCO2e/MWh, significantly influencing the carbon footprint of products manufactured there. The concentration of polypropylene resin production and injection molding capabilities in these regions has created integrated supply chains that reduce intermediate transportation requirements.

Regional Variation

Provenance Override Guidance

1. Submit certified material composition data showing actual polypropylene content percentages and any recycled material incorporation with third-party verification.

2. Provide facility-specific energy consumption records and local grid emission factors or renewable energy procurement documentation for the manufacturing location.

3. Supply detailed transportation logistics including shipping distances, modal split between ocean freight and trucking, and actual fuel consumption data for distribution routes.

4. Document production process specifications including injection molding parameters, cycle times, and energy efficiency metrics for the specific manufacturing equipment used.

5. Present end-of-life management data including actual recycling rates, waste diversion percentages, and regional disposal infrastructure capabilities for the target markets.

Methodology Notes

• The CCI score represents cradle-to-gate emissions for a standard 1.5 kilogram polypropylene storage bin including raw material extraction through manufacturing completion.
• Scope 1 emissions capture direct manufacturing energy use and polymerization processes at production facilities.
• Scope 2 accounts for purchased electricity consumption during injection molding and facility operations.
• Scope 3 encompasses upstream petroleum extraction, refining, transportation, and downstream distribution impacts.
• The functional unit assumes a 10-year useful life with capacity for multiple reuse cycles displacing single-use alternatives.
• Consumer use phase impacts are excluded as storage bins require no operational energy input during normal usage.
• Regional transportation assumptions may not reflect actual distribution patterns for specific market destinations.
• End-of-life recycling benefits are partially captured but vary significantly based on local waste management infrastructure.
