Indian companies do not distinguish between `Technology Absorption’ and Technology Adoption’. Comment.


This is necessary to understand the nature of technological change in general and its social implication in particular. Freeman has categorized technological change into the following three categories:

Incremental innovations: These are small and marginal improvements brought about by individual units and firms out of the experience of working with the specific process or the product. These generally give rise to productivity improvements or better products/process resulting in lower costs. Although each single incremental innovation may have relatively insignificant effect on the productivity or the cost, the cumulative effect of many of these innovations taken together may result in significant improvements. Also some of the management techniques like work study, organisation and methods (O&M), value analysis, etc, are used on specific processes with objective of productivity improvement and cost reduction and most of them would actually result in accelerated incremental innovation. The R&D efforts in India have often resulted in incremental innovation e.g., developments in auto industry.

Radical Innovation: These are major changes in the process or the product generally brought about by formal research and development efforts. Radical innovations are disjointed events, difficult to predict and have a substantial effect on productivity, cost and the quality of the product. Consequently, they act as catalysts for the growth of new markets. The development of a “jumbo” passenger aircraft, or one with supersonic speed would fit in this category as would the development of so many new drugs. Sometimes, a whole cluster of radical innovations develop, interlinked with each other, giving rise to the creation of new industries and services.

New Technological Systems: Some of the radical innovation, in course of time, end up development an entire cluster of many radical innovation interconnected with each other both technologically and economically, thus creating an entire new industry. The cluster of petrochemical innovation finally created a petrochemical industry and the cluster of synthetic materials innovation similarly gave birth to the synthetic materials industry. It is to be noted that the various radical innovations forming part of a new technological system are connected not only technologically but also economically.

1) Continuous monitoring of technology transfer plan at the product, divisional and corporate levels.
2) Training of engineers in identified areas at the collaborator’s works after familiarsing them with the documentiation received from the collaborator, so that they could derive the maximum benefits from their stary asyt the collaborator’s works.
3) Analysis of documentation, technical information etc. Received from the colloborators by the R & D groups and preparation of specific developmental plans for import substitution, product improvement cost reduction, etc. Keeping in view the innovations taking place internationally.
4) Entrusting the R & D group with the responsibility to carry out product improvement research so that the technology acquired is upscaled and improved upon further.
5) Associate the Technology Management Group from the initial stages of technology transfer plans including negotiations, training, dicussions, etc. held with the foreign collaborator.
The above trategies should help the organisation to absorb/adapt imported technology and achieve self-reliance at the earliest, thereby avoiding further imports of technology.
An on-line system for monitoring tecnology changes and a system for evaluation of their relevance and impact on the organisation have therefore to be given the foremost place in the organisation’s corporate planning process.
The above discussion is also relevant for a new organisation, as it is for asn existing set-up, except that it does not have previous experience and built-up technological capabilities, and hence has to generally acquire technological from elsewhere on perhaps lesser favourable terms. Any enterprise-new or existing, besides keeping track of the changes, has to keep itself in readinees to implement the changes at the fastest speed and thus keep its resources, such as funds, men and material always in readiness.
While an enterprise, on one hand, may establish its own R & d facilities and keep up the upgrading of the facilities, on the other, its process of technology evaluation has to be active all the time in orfer to remian competitive.
An enterprise must have a system of forecasting technological changes with time schedule and organise the human resorce (HR) structure in amnner that all unit operation, s individually and colelctively, are optimal.
Technology Management in Indian Cement Industry
Technolgoy Transfer Sceario in Cement Industry
Cement Industry has only recorded substantial growth since independence (from about 1 million tonners to 63 million tonne capacity) but also has undergone dramatic technological change. Starting with high-energy intensive, high manpower and practically no instrumentation, the industry now is high energy efficient, employs low manpower and has state of art instrumentation, including automation with expert system. The industry from a stage or having 97% of its capacity under the wet process has now 80% of its capacity under the dry process system. The compulsion process had to be reduced to half of what was then for each unit of cement produced. This study gives features of the technology changes which have takes place and are skill underway. The study is based on the proceedings of the national worshops on energy management in Cement Industry held at Hyderabad on 29th August, 1991.

Industry Profile
The Cement Indsutry has recoreded substential growth in the past decades. The installed capacity which was about million tonnes in 1950 has shot up to about 64 million tonnes in 1990-91. The acutal production of cement in 1990-91 was 48.75 million tonnes representing an average capacity utilisation of 76%. The cement demand at the end of 1994-95 is expected to be around 65 million tonnes. This implies that at the average capacity utilisation of 75% the installed capacity needed by 1994-95 would be around 85 million tonnes requiring an additional capacity creation of 21 million tonnes in the next four years. But, the current indications are that the installed capacity by 1994-95 would be only about 75 million tonnes implying shortfall of 10 million tonnes.
The structure of Indian Cement indsutry has undergone a significant change with respect to plant size and process employed. The industry has grown phenomenally in that last six years and after the cement decontrol and liberalisation policies, the industry is enjoying good times now with booming markets and better realisation of prices. But this is not a matter for complacence but an opportunity to aim at higher capacity utilisation, adopt energy efficient technology, etc. In the past decades, there has been a general shift towards dry process plants which are energy efficient compared to wet process. At present there are still 71 wet process kilns representing 16% of the industry capacity. Though in terms of units wet process kilns represent 43%, their share in production capacity is low at 16% due to lower ratings ranging between 200 to 60 tonnes per day (tpa). The industry is now wetnesing a steady move to higher capacity rating kilns of 1.0 million tpa. Further, some companies are already moving towards 1.5 million tonnes per annum capacity cement plants. Many Indian cement plants have already adopted latest technologies such as the precalciners which facilitate the use of high ash coals and time stone of inferior quality which leads to substantial fuesl and electricity savings.
Energy Consumption Trend
Cement manufacturing is an energy intensive operation with energy accounting for about 30% of the production cost. In terms of direct manufacturing costs, energy constitues 60% of the total direct costs. The sector consumes about 10 million tonnes of coal and 5.5 billion units of electricity. Of the total estimated demand in the industrial sector, the coal requirement in the current industry accounts for 5% and power requirement 4.5%
Systematic studies have been conducted in the country and abroad and what follows hereinafter has been identified as the techological improvement areas. All these area not only relate to energy conservation but also to adapting state of art technology.

Energy Conservation Approaches
Considering the vast magnitude of potentiality for energy in cement plants, it would be worthwhile classsifying the options under following categories:
Stage 1: Operational improvement and optimation measures and efficient electrical load management.
Stage 2: Retrofit (modernisation, expansion etc. of old or existing plants) options for energy conservation through improved process controls, capacity enchancement etc.
Stage 3: Adoption of state of art technology for energy efficiency improvements.
Energy Conservation opportunities
• Energy conservation opportunities in operational improvements and optimisation.
• Energy conservation opportunities through process controls, capacity enhancement / add-on devices.
• Energy conservation opportunities through adoption of state of art technology.
Appropriate technology cover the following broad areas:
a) conversion of wet process plants of dry process plants
b) conversion from preheater technology to precalciner technology.
c) Conversion of planetary coller system to grate cooler system.
d) Adoption of vertical roller mille in place of the traditional ball mille for grinding control and energy conservation.
e) Adoption of the state of art micro processor based controls for effective process control and energy conservation.
f) Use of alternative fuels such as lignite and natural gas in the case of plants with precalciner technology.
g) Adoption of on-line composition analysers to monitor and maintain raw meal mix in order to optimise on kiln heat consumption.
h) Simulation pilot plants for analysis of grindability index of raw meals, clinker and coal to enable judicious belending for grinding energy reduction.
i) Adoption of bucket elevator conveying system in place of pneumatic conveying system.
j) Adoption of rope way for material transport in place of traditional dumper system which is more energy intensive.
The power consumption in cement manufacturing is mainly spent in grinding and handling operations and hearly seventy per cent of it is consumed in raw material grinding, sintering and cement grinding systems. The energy consumption pattern is found to vary from one plant to another due to factors such as:
a) Age of the plant
b) Type of process adopted
c) Plant size capacity and system design
d) Plant layout and material handling system
Hence there cannot be a universal standardised approach towards conservation and each plant is required to be examined on its own merit.
Energy audit has to be done periodically to monitor efficient use of energy. This would include studying various operations using energy, and equipment and examining their relative efficiency / performance and adopting energy conservation methods.
Mobile energy diagnostic unit (energy bus) which is a unique facility equipped with latest and sophisticated facilities and on-board computer with relevant software for faster and accurate assessment of energy use pattern is available in the country, and can be used in cement plants.
Number of cement plants in the country have adopted some of these measures in various combination and have improved energy efficiencies. This has been achieved partially through technology acquisition and partially indigenous effort. The absorption of technology for equipment, process, operations and quality control has been of very high order and it is hoped that the remaining gaps will be further narrowed down from continuous technology development and upgradation efforts on the part fo machinery manufacturers, cement manufacturers and related R&D institutions. It may be mentioned here that most of the cement machinery manufacturers had technical foregin collaboration arrangements and are producing plants based on those imported technologies. Many cement plants with huge capacities such as Modi Cement and Gujarat Ambuja Cement have been built up with imported technologies from USA and other countries. While cement plants in India have quality control and testing facilities they have really not created any substantial R&d facilities, baring a few only such as Dalmia Cement and ACC. Most of them depend on the foreign technical support or support from machinery suppliers.
National Council of Building Materials (NCBM) at New Delhi, Central Building Research Institute at Roorkee, ACC Research Station at Thance (Bombay) are some of the main R&D institutions related to cement industry. The cement costs in India are not internatioally competitive due to various factors including technological deficiencies. Pollution control, waste utilisation, optimisation of operations are some other area which need more attention of the cement industry.
