  APPLICABILITY OF CLEANTECH I TECHNOLOGY OF CLEANER PRODUCTION I CASE STUDIES I PHOTO GALLERY I CONCEPT PRESENTATION

 

CLEANTECH as a management tool has universal applicability. However, experience reveals that the potential for implementation of CLEANTECH in a given facility or activity depends upon the following factor very significantly;

  1. CLEANTECH potential is directly proportional to the volume of the effluent: Examples to this could include paper mills, textile dyeing and processing, food processing industries, fast food chains and sewage handling systems.

  2. CLEANTECH potential is directly proportional to toxicity of materials/effluent: No one could imagine someone wasting cyanide, as the consequences are so well known.

  3. CLEANTECH potential is directly proportional to the hazard potential of process/materials: Examples could include the harrowing MIC leak in Bhopal or a liquid hydrogen transportation facility.

  4. CLEANTECH potential is directly proportional to cost of materials/wastes: Have you ever heard of a gold smith wasting materials.

  5. CLEANTECH is directly proportional to energy intensity of the process: The best example could be that of industrial drying processes in textile, paper and food processing sectors or the glass, ceramic and steel industries in particular.

Applying the above broad criteria and the experience of implementation, following could be some of the industries best suited for the implementation of CLEANTECH;

  • Pulp and Paper Industries. 
  • Drugs and pharmaceuticals. 
  • Textile dyeing and processing. 
  • Plywood and lamination industries. 
  • Metal heat treatment and surface finishing. 
  • Photo film industries. 
  • Leather processing industries.
  • Breweries and Distilleries. 
  • Food processing industries. 
  • Sugar Industries. 
  • Mineral processing industries. 
  • Butcheries and meat processing. 
  • Cement, glass and ceramic industries.
  • Asbestos based industries.
  • Chemical and petrochemical industries. 
  • Printing and Packaging industries. 
  • Coal based industries. 
  • Industries handling PCBs and other chemicals of concern. 

The above list could however be best stated as illustrative and not exhaustive. It only includes industries, where CLEANTECH could be implemented easily and readily reaping the low hanging fruit and to establish the usefulness of the techniques of cleaner production so as to motivate increasing number of facility owners and managers to adopt CLEANTECH for pollution control at profit. In actual practice, it could be gainfully implemented in every facility or activity. The best examples of other than manufacturing industries could be the public services like hospitals, transport, sewage handling & treatment and construction. A public or private sector office could be no exception to the above.

Some Possible CLEANTECH Initiatives

  • Totally chlorine free bleaching of pulp in paper mills

  • Lignin separation from black liquor for valorization

  • Chemical free processing of cane juice in sugar mills

  • Wastepaper de-inking for recycling in paper mills

  • Microwave heating/drying in food/ textile industry

  • Computer aided design, simulation and process control

  • Bio pulping & bio bleaching of pulp & paper

  • Freeze concentration of waste stream to recycle concentrate
