General Bisphenol A is used as an intermediate (binding, plasticizing, hardening) in plastics, paints/lacquers, binding materials and filling-in materials. The substrate is mainly used for the production of polycarbonate resins (71%) and epoxy resins (27%). Furthermore bisphenol A is used as an additive for flame-retardants, brake fluids and thermal papers. The current (1999) world-wide production of bisphenol A is approx. 2,000 ktonnes/year. Over the next 5 years, overall production is believed to grow to around 3,500 ktonnes/year in 2005. Sources and emissions The production of bisphenol A in the Netherlands in 1999 was around 280 ktonnes/year, which is approx. 35% of the total production in Europe and around 14% of the total world production. A review of all produced, used amounts and emissions is given in Table 1. Over the years bisphenol A consumption has more than doubled. From 1993 to 1996, total consumption for polycarbonates grew with 11.6% per year and is expected to continue to grow at an average annual rate of 7.6% during the period 1996-2001. Bisphenol A consumption for the production of epoxy resins will also grow but more moderately. In 1999 annual bisphenol A consumption in Europe is estimated at 680 ktonnes. Total polycarbonate consumption in the Netherlands is 14 ktonnes/year while other consumption of bisphenol A based products is 11 ktonnes. Emissions of bisphenol A may occur during bisphenol A production, production of products using bisphenol A and from products in-use. Emission during bisphenol A production is around 2 tonnes/year to surface waters and 1 tonne to air. The most important emissions during bisphenol A product processing occur during production of phenoplast cast resins (43 tonnes to water in Europe), thermal paper production (151 tonnes to water in Europe) and the use of bisphenol A as inhibitor during PVC production (25 tonnes to water in Europe). Total emissions are 2.1 tonnes to air, 199 tonnes to water and 30 tonnes to soil in Europe. The specific emissions for the Netherlands are unknown. Emissions from products in-use are estimated at 160 kg from polycarbonates and
