Katalyyttejä käyttämällä voidaan rajoittaa ympäristölle haitallisten komponenttien muodostumista ja valmistaa ympäristölle haitattomampia tuotteita. Myös prosessien raaka-ai-neiden kulutusta ja jätteiden muodostumista voidaan vähentää katalyyttien avulla. Kemianteollisuus on siirtymässä ympäristövai-kutustensa vähentämisessä yksinkertaisista poisto-tekniikoista päästöjen muodostumisen estämiseen. Oikein valittuihin, selektiivisiin katalyytteihin perustuvien prosessirat-kaisujen uskotaan muodostuvan taloudelliseksi vaihtoehdoksi tuotannon ympäristöhaittojen minimoinnissa.%Catalysis is one effective way to control pollution of the environment, now and in the future. New catalytic technologies are helping to protect the ozone layer, reduce the greenhouse effect, create environmentally safer transportation, solve environmental problems of energy production, purify the emissions of chemical and other industries, raise energy efficiency, minimize the use of raw materials and process renewable raw materials. Reformulated fuels that are environmentally more friendly can be produced via new catalytic processes, as can substitutes for CFC compounds. NO_x, SO_x, VOCs, CO, CH_4, and the automotive exhaust gases as well as O_3, N_2O, and CO_2 can be converted to less harmful products by catalytic processes. Catalysts for the oxidation of aqueous organic compounds in wastewater treatment are being developed. Re-use of by-products from the chemical industry, odour control and toxic waste gas purification are areas where catalytic processes will play a major role. Beyond the existing technologies, there are still many opportunities for innovation and for improved and fundamental understanding of the new catalytic technologies in environmental protection. Particularly important is the application of catalytic technologies in processes that use fewer toxic raw materials, eliminate hazardous by-products and produce less emissions. By the year 2000, the manufacture and use of catalysts for environmental protection will be on a more scientific basis than today.
