Reusable Microfibre Cloth

Material Composition Assumptions

A typical reusable microfibre cloth weighs approximately 100 grams and consists primarily of synthetic polymer fibers derived from petrochemical feedstocks. The standard composition includes polyester fibers comprising 70% of the total weight, contributing roughly 70 grams to the overall mass. Polyamide or nylon fibers constitute the remaining 30%, adding approximately 30 grams to provide enhanced durability and cleaning performance. These synthetic materials undergo specialized processing to create the characteristic split-fiber structure that enables superior dirt and moisture absorption compared to traditional cotton alternatives.

Manufacturing Geography

The majority of global microfibre cloth production occurs in China, which accounts for over 60% of worldwide synthetic textile manufacturing capacity. Chinese facilities benefit from established petrochemical supply chains, specialized textile machinery, and economies of scale that reduce per-unit production costs. However, the carbon-intensive electricity grid in China, with an average intensity of 555 gCO2/kWh, significantly increases the embedded emissions from energy-intensive fiber production processes. Manufacturing operations require sustained high temperatures for polymer extrusion and rapid cooling systems for fiber formation, making electricity consumption a major contributor to the overall carbon footprint.

Regional Variation

Manufacturing Region	Grid Intensity	Estimated CCI Score	Adjustment vs Default
China	555 gCO2/kWh	38	Baseline
India	708 gCO2/kWh	43	+13%
Turkey	387 gCO2/kWh	32	-16%
Germany	348 gCO2/kWh	30	-21%
Norway	98 gCO2/kWh	22	-42%

Provenance Override Guidance

1. Factory-specific electricity consumption data per kilogram of finished microfibre cloth production, including detailed breakdowns of energy use during polymer processing, fiber extrusion, and textile finishing operations.

2. Renewable energy certificates or power purchase agreements demonstrating the percentage of manufacturing electricity sourced from wind, solar, or hydroelectric generation rather than grid-average power.

3. Raw material traceability documentation showing the carbon intensity of polyester and polyamide feedstocks, including whether recycled content displaces virgin petrochemical inputs.

4. Transportation manifest data detailing shipping distances, modes of transport, and fuel consumption from manufacturing facility to final distribution centers.

5. Water treatment system specifications and energy consumption for managing wastewater generated during textile dyeing and finishing processes.

Methodology Notes

• The CCI score represents cradle-to-gate emissions including raw material extraction, polymer production, textile manufacturing, and distribution to retail locations
• Scope 3 emissions dominate the profile due to downstream microfiber pollution during consumer use phases and challenging wastewater treatment requirements
• Functional unit assumes a standard 100-gram microfibre cloth with typical polyester-polyamide blend composition
• End-of-life disposal impacts are excluded due to varying regional waste management practices and limited incineration emission factors
• Consumer washing frequency and water heating energy consumption show high variability across households and geographic regions
• Microfiber release quantification relies on laboratory studies that may not fully represent real-world washing machine conditions and filtration system performance
