Water reuse and energy reductions are production disclosures with explicit denominators
Management says its domestic bases applied waste-glass-fiber recycling and pure-oxygen combustion technology and links these processes with lower unit energy consumption and emissions. It describes a water-reuse system with a biological-membrane treatment system handling 4,800 tonnes of wastewater per day. This is wastewater handling, not glass-fiber production capacity or a separately identified furnace. For FY2011 it reports reductions from the prior year of 10.10% in energy per unit of enterprise value added, 6.10% in energy per unit of current-price output value and 5.50% in energy per unit of glass-fiber yarn. The first two economic denominators differ from the physical yarn-output denominator. It also reports 18.26% lower wastewater discharge per unit of yarn and 36.27% lower chemical oxygen demand, or COD, per unit of yarn. These intensity measures connect resource use and discharge with production, but do not establish falling absolute group energy use or total pollution. The company's stated goal for total emissions is retained as a goal rather than a proven result, and the passages do not allocate the reductions among specific lines or quantify annual savings attributable to each technology.
