Environmental Sustainability Comparison of Technologies
topic
Environmental sustainability comparison of shuttleless loom technologies assesses energy consumption per square metre of fabric produced with air-jet having the highest energy intensity from compressed air, noise emissions where air-jet at 95 decibels exceeds rapier at 83 decibels and water-jet at 78 decibels, water consumption and wastewater from water-jet operations, lubricant use and waste from mechanical systems, and carbon footprint per fabric unit at different electricity generation carbon intensities that influence the relative environmental ranking as grid decarbonisation changes the air compression energy carbon intensity.
Role
Provides the environmental performance comparison that increasingly influences technology selection as sustainability reporting requirements, carbon pricing, and corporate environmental commitments become factors in capital investment decisions alongside the traditional financial and technical criteria, with air-jet's high compressed air energy consumption being an increasing disadvantage in high-electricity-cost and high-carbon-intensity grid environments that make its energy intensity more financially and environmentally costly.
