Instant Noodles (cup)

Material Composition Assumptions

Cup-based instant noodles contain several distinct material components with varying environmental impacts. The wheat-based noodle block comprises approximately 65 grams and represents the largest single component by weight. Refined vegetable oils account for roughly 12 grams, with palm oil making up 15-20% of the total oil content used in the frying process during manufacturing.

The polystyrene or foam cup packaging weighs approximately 8 grams and provides the primary structural container for the product. Paper-based components including the lid and outer cardboard packaging contribute an additional 6 grams to the total weight. Plastic film wrapping adds roughly 2 grams for moisture barrier protection.

Dehydrated vegetables and seasoning packets represent the remaining 7 grams of product weight. These components undergo specialized processing including freeze-drying and salt-based preservation methods that extend shelf life while maintaining nutritional content.

Manufacturing Geography

Asia-Pacific regions dominate global instant noodle production, with China, Japan, and Indonesia serving as the primary manufacturing hubs. These countries benefit from proximity to wheat growing regions and established supply chains for vegetable oil processing facilities.

The regional grid intensity of 0.58 kg CO2e per kWh reflects the coal-heavy electricity generation mix common across major manufacturing centers. This relatively high carbon intensity significantly impacts the manufacturing phase emissions compared to regions with cleaner electricity sources.

Production facilities in this region also benefit from lower labor costs and established expertise in noodle manufacturing techniques developed over several decades. The concentration of packaging suppliers and seasoning producers creates additional cost efficiencies that reinforce the geographic clustering of production.

Regional Variation

Manufacturing Region	Grid Intensity	Estimated CCI Score	Adjustment vs Default
Asia-Pacific (China)	0.58 kg CO2e/kWh	52	Baseline
North America (US)	0.42 kg CO2e/kWh	47	-10% reduction
Europe (Germany)	0.39 kg CO2e/kWh	45	-13% reduction
Nordic (Norway)	0.12 kg CO2e/kWh	38	-27% reduction
Southeast Asia (Thailand)	0.51 kg CO2e/kWh	50	-4% reduction

Provenance Override Guidance

1. Supplier-specific electricity consumption data for noodle production lines including frying or drying processes with documentation of actual grid mix or renewable energy certificates

2. Detailed ingredient sourcing documentation showing wheat origin, vegetable oil composition with palm oil percentages, and certification status for sustainable agriculture practices

3. Packaging material specifications including cup material type, recycled content percentages, and supplier location data for polystyrene or alternative packaging materials

4. Transportation mode and distance records from ingredient suppliers to manufacturing facilities and from production sites to distribution centers

5. Manufacturing process energy audit results showing natural gas consumption for heating and steam generation alongside electricity usage for machinery operations

Methodology Notes

• The CCI score represents cradle-to-gate emissions covering raw material extraction through manufacturing and packaging, with additional consumer preparation phase included due to the product requiring hot water for consumption
• Scope 3 emissions dominate due to agricultural inputs and palm oil production impacts, while consumer preparation represents the largest single emission source through water heating energy requirements
• Functional unit is defined as one complete instant noodle cup product weighing approximately 100 grams including all packaging components
• End-of-life disposal impacts are excluded from the current assessment due to high variability in regional waste management systems and recycling infrastructure
• Data gaps exist around specific agricultural practices for wheat production and detailed supply chain transportation modes, creating uncertainty in upstream emission calculations
