Eco-efficiency is critical for
organisations that seek to be both environmentally conscious and
profitable. It helps to "produce more out of less" to avoid wasting
natural resources and to reduce emissions and damage to the environment.
The textile coating and laminating industry, utilising solvent or
water-based polymeric mixtures, is one of the industries coming under
extreme environmental pressure to replace traditional procedures and use
eco-efficient coating agents. In this study, eco-efficiency analysis was
used to compare the eco-effectiveness of two different coating agents,
polyacrylate and polyurethane, each in organic solution as well as
aqueous dispersion forms. The "ecological fingerprint" and
eco-efficiency portfolio were graphically illustrated for these coating
agents based on the customer benefit, defined as coating one square
meter of a textile fabric in a conventional laminating unit. According
to the analysis results, polyacrylate dispersion in water was the most
eco-efficient coating agent whilst polyurethane resin dissolved in
organic solvent was found as the coating agent with the least
acceptability as an eco-efficient product.
