INTERNATIONAL CLEANER PRODUCTION INFORMATION CLEARINGHOUSE

CASE STUDY #32 1. Headline: Reducing emissions in steel pipe coating 2. Background: NIF-NOT: Targeting cleaner production in Poland The NIF-NOT Cleaner Production Program is an independent, cooperative venture between the Societies of Chartered Surveyors from Norway (NIF) and Poland (NOT). Sponsored by the Norwegian and Polish governments, the program has been in operation since 1991. After three years of active work throughout the country, over 400 companies and institutions (such as universities and local authorities) and more than 600 individuals have participated in the program. Between 1992 and 1993, the Polish Ministries of Environment, Industry and Trade signed a Letter of Intent, aimed at achieving sustainable industrial development based on cleaner production as an environmental management tool. A Declaration of Cleaner Production was subsequently issued, to be signed by companies accepting the goals of the Letter of Intent, and applying the Cleaner Production strategy at company level. Added to the NIF-NOT program, these two documents have created a more formal and permanent structure, and stronger support for the program. At the time of writing, over 150 companies have signed the Declaration and are working in accordance with the Cleaner Production strategy. According to clients' requirements, the Ferrum steelworks manufacture steel pipes must have an outside insulation which is corrosion resistant. The pipes are coated with a bitumen compound , a coating process which is very harmful to the environment, producing toxic gaseous emissions of 47.6 tons/year and generating 194 tons/year of solid waste. The Ferrum steelworks manufacture a wide range of pressure and galvanizing tanks, boiler drums, turbine pipelines, constructions for metallurgical and building machine industries, and steel pipes. The company employs approximately 1 500 people. 3. Cleaner Production Principle: New technology 4. Description of Cleaner Production Application: The new coating technology consists of the following process. - shot blasting - successive deposition of: * powdered epoxide resins * copolymer as a combining agent * ethylene plastics as the outside layer. 5. Economics: Reduction in environmental fees and operating costs US $3.5m Capital investment US $6.2m Payback period 1.75 years These figures are based on a production rate of 670 000 m2 of insulated coating. The capital investment was half- financed by a low-interest loan from the National Environment Protection Fund. 6. Advantages: Use of the new coating technology has resulted in reductions in the emission of aromatic and aliphatic hydrocarbons and in solid wastes. This has led to a decreased impact on the municipal waste dump, and improved air standards in the surrounding area. Harmful bituminous substances have been eliminated, and the lifetime of the pipes has been prolonged by 100 per cent.
