Disposable Paper Coffee Cup

Material Composition Assumptions

A standard disposable coffee cup weighs approximately 20 grams and consists primarily of virgin bleached paperboard forming the structural base at 19 grams or 95% by weight. The inner surface receives a thin polyethylene coating at 1 gram representing 5% of total weight, which provides liquid barrier properties but complicates recycling processes. Additional sizing additives are incorporated during paperboard formation to enhance wet strength characteristics. Accompanying plastic lids composed of polystyrene add another 2-3 grams but are typically assessed as separate line items in environmental accounting.

Manufacturing Geography

Production concentrates heavily in Nordic European countries where integrated forest product facilities benefit from abundant renewable wood fiber resources and relatively low-carbon electricity grids. Finnish and Swedish manufacturers dominate the market due to proximity to sustainably managed boreal forests and grid electricity averaging 45 gCO2/kWh from the Nordic electricity mix. These facilities often operate combined heat and power systems utilizing wood waste biomass, further reducing the carbon intensity of manufacturing operations compared to regions dependent on fossil fuel-powered production.

Regional Variation

Manufacturing Region	Grid Intensity	Estimated CCI Score	Adjustment vs Default
Nordic Europe	45 gCO2/kWh	48	Baseline
United Kingdom	233 gCO2/kWh	55	+15%
Eastern Europe	520 gCO2/kWh	62	+29%
Australia (renewable sites)	35 gCO2/kWh	44	-8%
China (average grid)	555 gCO2/kWh	63	+31%

Provenance Override Guidance

1. Submit facility-specific electricity consumption data with renewable energy certificates or power purchase agreements documenting clean energy sourcing arrangements.

2. Provide documentation of recycled fiber content percentages with chain-of-custody certification, as post-consumer recycled content can reduce upstream forestry impacts.

3. Supply waste heat recovery system specifications and efficiency measurements, particularly for integrated pulp and paper operations utilizing biomass energy sources.

4. Document transportation distances from fiber sourcing locations to manufacturing facilities, including modal split between truck, rail, and water-based freight options.

5. Provide end-of-life infrastructure partnerships or take-back programs that demonstrate higher recycling rates than regional averages for polyethylene-coated paper products.

Methodology Notes

• The CCI score represents cradle-to-grave emissions including forestry, pulping, manufacturing, and landfill disposal for a standard single-wall paper cup with polyethylene lining.

• Scope 3 dominance reflects the significant upstream impacts from virgin fiber extraction and downstream methane emissions from landfilled organic materials.

• Functional unit assumes a 12-ounce capacity cup suitable for hot beverage service with standard barrier coating performance requirements.

• Plastic lid emissions are excluded from this assessment as lids represent separate SKUs with distinct material compositions and supply chains.

• Current data gaps include limited visibility into regional recycling infrastructure effectiveness and variations in forestry carbon sequestration accounting methods.

• End-of-life scenarios assume typical European waste management with 36% recycling rates and remainder directed to landfill with methane capture efficiency of 50%.
