Modeling Clay (set)

Material Composition Assumptions

A typical modeling clay set contains multiple components with varying environmental impacts. The primary material consists of clay or polymer-based compounds that form the moldable medium, representing approximately 200-400 grams or 70-80% of the total product weight. Pigments and colorants comprise roughly 10-20 grams or 3-5% of the set, providing the range of colors available to users. Packaging materials including plastic containers, cardboard boxes, and instruction materials account for the remaining 15-25% of the total weight, typically ranging from 50-100 grams depending on the set size and presentation format.

Manufacturing Geography

The majority of modeling clay sets originate from manufacturing facilities in China, where established petrochemical and plastics industries support polymer clay production. Chinese manufacturing benefits from integrated supply chains for both traditional clay materials and synthetic polymer bases. The regional grid intensity of 555 gCO2/kWh reflects the coal-heavy electricity mix that powers these manufacturing operations, significantly influencing the carbon footprint of energy-intensive polymer processing and clay preparation stages.

Regional Variation

Manufacturing Region	Grid Intensity	Estimated CCI Score	Adjustment vs Default
China	555 gCO2/kWh	Data insufficient	Baseline
Germany	366 gCO2/kWh	Data insufficient	Lower emissions expected
United States	386 gCO2/kWh	Data insufficient	Lower emissions expected
India	708 gCO2/kWh	Data insufficient	Higher emissions expected
South Korea	436 gCO2/kWh	Data insufficient	Lower emissions expected

Provenance Override Guidance

1. Submit detailed material composition data specifying the exact polymer formulations, clay mineral content, and pigment types used in the specific product formulation.

2. Provide manufacturing facility energy consumption records including electricity usage, fuel consumption, and any renewable energy sources utilized during production.

3. Document transportation logistics covering raw material shipping distances, manufacturing location, and distribution pathways to final retail destinations.

4. Supply packaging specifications detailing all container materials, weights, recycled content percentages, and end-of-life disposal or recycling capabilities.

5. Include any third-party lifecycle assessment studies or environmental product declarations specific to the modeling clay formulation and manufacturing process.

Methodology Notes

• Current CCI score estimates are unavailable due to insufficient peer-reviewed lifecycle assessment data for modeling clay products in academic literature
• Manufacturing processes typically generate the majority of lifecycle emissions for clay-based products, though specific scope breakdowns cannot be determined without comprehensive study data
• Functional unit represents one complete modeling clay set as sold to consumers, including all clay materials and associated packaging
• Assessment excludes use-phase activities, end-of-life disposal scenarios, and retail distribution beyond manufacturer gate
• Significant data gaps exist regarding polymer clay formulation variations and their respective carbon intensity differences across product lines and manufacturers
