The concept of Clean Technology : CT
The concept of Clean Technology was first introduced in 1989 by the Industry and Environment Programme Activity Center (IE/PAC) under United Nations Environment Programme (UNEP) and became widespread throughout the world, especially in the industrialized countries. Clean Technology was one of the main topics in World Environmental Summit in 1992. Thailand started to introduce Clean Technology to the industrial sector in 1990 and the concept became widespread in 1997. The Department of Industrial works of Thailand has implemented the Cleaner Production technology in the domestic industrial sector to promote productivity and reduce pollution, as well as improve the competitiveness since 2000. The main activities of Clean Technology in Thailand are as follows:
- Development and establishment of guidelines for production process improvement and activities promoting manufacturing
- Development of industrial production factors determining the process efficiency for each type of industries to identify the loss occurred during production and the environmental impacts
- Establishment of the standard procedures for cleaner production for each type of industries (increase productivity and pollution prevention)
- Human resource development and cleaner production information support.
Clean Technology is a pollution and residue reduction process that can minimize pollution and residues from process as much as possible or close to zero. The concept is reducing produced residues by determining their sources which can be resolved by changing material, management system, technology and product. Besides managing source of residues, clean technology can also be used to manage final residues by reusing or recycling until the residues cannot be further utilized beside subjecting to treatment process.
