Abstract

1. Title A plan of managing system on Environmental technology development(Ⅰ) Report on the basic demand of environmental technology development in industries. 2. Objectives of the project The basic demand of environmental technology development in industries was widly investigated to promote the development of domestic environment techhology and to establish a plan of managing system on environmental technology development. 3. Period of the project from June 19, 1993 to December 31, 1993 (7months) 4. Contents of the project Generally a level of Domestic environment technology is around 20～30% to that of advanced countries. To promote the development of environment technologies, this report analyzed the environment technologies required in domestic and described the present status of environment technologies in industries to manage the supply and demand of the technologies efficiently. For this purpose, the production and discharge of the pollutants in both the whole industries and each industrial unit were analyzed as well as the productivities according to the '91 and '92 source inventory data of Ministry of Environment. Several aspects of end-of-pipe technologies and environmentally sustainable technologies which were currently applied for pollution prevention were investigated. Also, the present status of pollution in noise and vibration, odor, flying dust, soil and groundwater, and marine as well as air, wastewater and waste were described. After that, the required environmental technologies for pollution prevention were studied. 5. Results and Reconmandation Based on the Korean Standard Industrial Classification and Classification used in waste management, industries were grouped 9 main and 40 sub-classification. From these industries, a total productivity in 1992, Korea was equivalent to 187,802.4 billion won which shares the manufacture, construction, finance, security, real estate, whole and retail sale, and accomadation, etc. in sequences. Producing amounts of air, water, special waste, solid wastes from the industries are 4,088.6 kt/yr(82% of the total 4,966.6kt/yr), 82,008.8k㎥/day(44.5% of the total 82,008.8k㎥/day), 7,804kt/yr, 48,058kt/yr(39% of the total 123,154kt/yr), respectively. Specified amounts of the industrial air pollution produced by the industries were described. Numbers of the point and the non-point sources of air pollutants were 38,375 and 6,994,443 which produced 55% and 45% of total pollution, respectively, and 84.6% of the total amount of the total ameunt of the air pollutants, was generated from fossile fuel. Only 0.7% of the 2,025,616 total factories, 5% of the total 14,715 manufacturing factories polluted water due to their industrial wastes which was 8,200.8k㎥/day(44.5%) of the total national waste water. Of the total national solid wastes, the industrial waste was 48,058kt/yr(39%) and the special waste was 7,804kt/yr generated from 5,172 factories. We estimated a total amount of wastes would reach to the double of this figure in the early of 21 century which requires the higher effecacy of the environmental technologies than these days. In chapter 4 and 5, we described the environmental sustainable technologies and end-of-pipe technologies which may permit to secure the national and international environmental markets, and to increase the efficacy of the prevention of degree of the pollution. Further, these technologies should be applied by industries for decreasing cost. Also, specific environmental clean technologies should be developed consistently for pollution-inducible factories.
