Dishwasher Tablets (pack of 30)

Material Composition Assumptions

Based on typical dishwasher tablet formulations, each tablet weighs approximately 20.5 grams with the following estimated composition:

• Surfactants (ethoxylated alcohol): 6.2g (30%)
• Palm kernel oil derivatives: 4.1g (20%)
• Sodium percarbonate (oxidizing agent): 3.1g (15%)
• Sodium bicarbonate: 2.5g (12%)
• Sodium pyrophosphate (builder): 2.1g (10%)
• Sodium silicate: 1.6g (8%)
• Enzymes (protease, amylase): 0.6g (3%)
• Polyvinyl alcohol (PVA) film wrapper: 0.4g (2%)

The total package weight for 30 tablets is approximately 616 grams, with additional cardboard packaging adding roughly 50 grams.

Manufacturing Geography

Primary manufacturing occurs in China, where large-scale chemical processing facilities produce both the active ingredients and final tablet formulations. China’s manufacturing dominance stems from established surfactant production infrastructure and proximity to palm oil supply chains from Southeast Asia. The regional grid intensity of 555 gCO2e/kWh significantly influences the manufacturing emissions profile, particularly during energy-intensive chemical synthesis and tablet compression processes.

Regional Variation

Manufacturing Region	Grid Intensity	Estimated CCI Score	Adjustment vs Default
China	555 gCO2e/kWh	52	Baseline
Germany	366 gCO2e/kWh	48	-8%
United States	386 gCO2e/kWh	49	-6%
India	708 gCO2e/kWh	58	+12%
Brazil	87 gCO2e/kWh	41	-21%

Provenance Override Guidance

1. Manufacturing facility energy consumption data (kWh per kg of product) with renewable energy procurement certificates
2. Supplier-specific palm oil sourcing documentation including land use change factors and transportation distances
3. Detailed surfactant production methods with energy intensity measurements for ethoxylated alcohol synthesis
4. PVA film supplier data including polymer production methods and packaging weight optimization metrics
5. Regional water heating energy requirements and consumer usage pattern studies for target markets

Methodology Notes

• The CCI score represents cradle-to-grave emissions for one complete package of 30 dishwasher tablets including typical consumer use patterns
• Scope 3 dominance reflects the energy-intensive nature of heated water during the dishwashing process, accounting for the majority of lifecycle emissions
• Functional unit assumes standard dishwasher cycles with average water heating requirements across residential settings
• Manufacturing emissions exclude facility construction but include chemical processing equipment energy consumption
• Regional grid intensity variations significantly affect both production and use phase emissions depending on local electricity generation mix
• Palm oil sourcing emissions include estimated land use change factors but exclude potential deforestation impacts due to data uncertainty
• Microplastic release during use phase is noted but not quantified in carbon equivalent terms due to methodology limitations
