IS THERE A DECLINE IN INDIAN CHEMICAL MANUFACTURING SECTOR?
Considering the level of technology developed and adopted in the developed countries and the need to be globally competitive in the present era of liberalization and globalisation, Indian manufacturing sector, on the whole, appears to be feeling somewhat nervous and diffident. In short, there appears to be a crisis of confidence among the manufacturing sector in India particularly in the fast changing chemical industry.
The other two units in South India namely Madras Fertilisers Ltd. in Chennai and FACT in Kerala are in doldrums and face the threat of closure before long if appropriate revival and rehabilitation programmes for these units were not to be worked out by the Government of India immediately.
Further, as there is tremendous enthusiasm amongst the job seekers and investors to involve themselves in service oriented functions which appear to be having less risk and generally perceived to provide quicker results compared to the manufacturing sector, the progress and development of manufacturing sector are being considerably affected. In the long run, such trend would not do good to India, as it would result in wiping out the excellent benefits and knowledge gained over several decades in developing and stabilising the manufacturing industry. Lesser importance to the manufacturing sector as an investment activity and providing greater stress on service oriented investment activity would lead to weakening the basic structure and strength of the industries and the over all national economy itself in the long run . More than the services sector, manufacturing activity would only provide core strength to the task of building up a strong industry based economy.
The present conditions call for urgent measures and proactive policies to strengthen the manufacturing sector in chemical industries in all possible ways.
Perhaps, possibly one reason for the falling fortunes of chemical manufacturing sector in India is the reluctance of Indian industries to invest in technology, which is one of the pre conditions for the growth and optimisation of performance and progress of chemical industries. Continued focus in research and development activities with long term plans and carefully identified goals and targets are necessary.
There is always an element of risk involved in research and development functions and this is part of the challenges and opportunities facing the chemical industries. The reluctance to invest and labour hard in the research and development activities would be sure way of retarding the progress of chemical industries.
For a long period, India has been remaining by and large as mere buyer and recipient of technologies. There are not many claims in India for the development of basic technologies, though there have been some isolated instances of excellent and credit worthy achievements in the field. A large number of research and development bodies set up by the government and huge facilities created in several universities have not provided benefits commensurate with the investment made. As a matter of fact, the progress of chemical industry in the past have been only to the extent of technologies made available to the country by the multi national companies, that are based in developed countries .
With the globalisation of economy and not much restriction for transportation of products and goods from one country to the other, acquisition of technology in the specialised areas have become very difficult. The competitive technologies are not any more available for ready sale.
With technologies being not available and indigenous efforts proving to be unequal to the demand and requirement, the net result is that manufacturing sector in the country is getting neglected.
The technology crisis in India can be well realized, if one would know that India is unable to set up facilities for several chemical products which have demand in India and great prospects internationally, due to want of indigenous technology and difficulty in securing technology from abroad. There are many such products which include synthetic vanillin, coumarin, poly vinyl alcohol, titania slag etc. etc.
The Indian industries and the government should discuss this subject with great concern immediately and work out some long term strategies. A well coordinated approach between industries, government owned CSIR labs and universities are urgently called for.
Strengthening the manufacturing sector in the chemical industries in a meaningful way is possible only by encouraging strong indigenous technology development capability.
GLOBAL PHOTOVOLTAIC INDUSTRY – PROFILE
Worldwide, annual installations by the photovoltaic (PV) industry grew from 4,000MW in 2002 to 1.7GW in 2006, an average annual growth rate of over 42%.
According to the European Photovoltaic Industry Association, installations of new solar capacity in the US totalled 141MW in 2006, while the cumulative installed capacity of solar modules worldwide reached just below 7GW.
Currently, over 90% of global PV production is silicon wafer-based. Solar cell semiconductors can be made from other materials such as cadmium telluride and copper indium diselenide, but the easy transferability of silicon technology from the electronics industry and the long history of silicon based semiconductors make silicon by far the most popular material for solar cells.
Strong 40%+ PV industry growth began in 2003 and is yet to stop. The demand for silicon for PV cells has led to industry wide material shortages and increasing silicon feedstock prices.

Propylene is a colourless, flammable gas that forms explosive mixtures with air.
Propylene consumption is dominated by polypropylene (PP), which accounts for about 60% of global demand and has been the fastest growing of all the major propylene derivatives. Other important derivatives are acrylonitrile, oxo alcohols, propylene oxide, cumene and acrylic acid. Smaller uses are in oligomers, isopropanol and fine chemicals.
Propylene is a byproduct of the production process of ethylene through steam cracking of oil or natural gas.
It is a coproduct of fluid catalytic cracking (FCC) at petroleum refineries. At present, propylene is produced mainly by two sources namely heavy feed crackers and fluidised catalytic crackers (FCCs) in refineries.
Supply scenario of propylene is likely to remain tight in the global market.

Stevia rebaudiana Bertoni is a herbaceous perennial plant belonging to the Asteraceae family. It is native to the oriental region of Paraguay.
The leaves of Stevia plant are 20-30 times sweeter than the regular sugar we use. Apart from being natural unlike other sweeteners, it is also found to be zero calorie.
The crop was first established in Japan in 1968. By mid-1970s, standardized extract and pure stevioside was utilized commercially in Japan for sweetening and flavouring foods and beverage as a substitute for several synthetic sweeteners.
The crop has been introduced in several countries, including Brazil, Korea, Mexico, USA, Indonesia, Tanzania, India and Canada.
