First Day Poha making factory:
Poha factory visit was on 5th October in Pen, Narangi. We saw it in batches. We started with the main area where paddy (raw material) was kept.
Joshi Poha Factory:
Joshi Poha factory was established in 1948, the factory produces flattened rice (poha) flakes which are an ingredient of a major snack, in Maharashtra. The raw material used for this is paddy and is procured within the Taluka at the rate of Rs. 14/kg. If local people get their own paddy to make poha then the cost if Rs. 5/-. Many varieties of paddy are used like Ratna, Jaya, Suvarna, Karjat, Sahyadri. Capacity of the poha factory is 20 quintals.
Flow chart:
Figure 2: Flow chart of Poha making
• Paddy is cleaned and impurities are removed then it is soaked in hot water for 3 hours. If the paddy is straight from plant i.e. moist, one doesn’t need to soak it in water.
• After drying i t in shade overnight, paddy i s p u t i t i n t h e h o p p e r a n d g o e s i t i n roaster ( w i t h s an d ) in a n oven with big rotating s t e e l drum ( a t 2 1 0 d e g r e e C e l s i u s ) to remove moisture. Roaster driving motor was of 5 HP.
Figure 3: Roaster in action
• Roasted paddy comes out and some fraction of it gets popped
• These flakes are then passed through sieves to remove unwanted material (husk)
• Husk obtained from sieve machine is treated as a fuel (put in hopper) for this oven. The fly ash is used as an additive in brick making.
• These filtered flakes are passed through a roller to flatten them. S t arch hel ps i n get t i n g i t fl at t ene d. The degree of flatness is adjusted by varying pressure applied by hand.
• Flakes thus obtained are of fairly even size but some would be whole, some broken in the process which are also separated.

The capital required to create one job for the poha mill that we visited is estimated to be about Rs.20750. Although the enterprise itself is not capital intensive, a major factor that
Sathe Rice mill:
After visiting the Poha factory, we headed towards Sathe rice mill situated further ahead.
The rice mill was established in 1910. It is a major industry in Pen since large number of paddy fields exists. The mill employed a r o u n d 10 workers, out of which 2-3 handled the milling jobs and the remaining handled the packing and transportation. As per the input from some employees, they receive a daily input of about nearly 80 quintals. The f i n a l o u t p u t i s s o l d a t R s . 1 5 0 p e r q u i n t a l . Being a medium scale set-up, a minimum of 30kg input is required for an individual operation cycle.
Figure 4: Economic determinant for Rice Milling
As we can see in figure 4, the raw material (paddy) is taken from rural area and the finished product is also consumed within the rural area. Surplus finished product is also sent to outside environment.
The various steps followed in making of Rice Mill are as follows:
Flow chart:
Figure 5: Flow chart of rice mill
First the paddy is de-stoned and put through a conical structure below the ground level from where the paddy is lifted using lifts.
Paddy is then put through de-husker (two rubber wheels) where the husk is removed.
The husk is removed through various zigzag sieves.
First level of polishing is done and bran is removed.
Final whitening (second level) of polishing is done.

Compared to a poha mill, the rice mill needs higher initial capital investment as the complete process is mechanized. The capital needed to create one job in the rice mill that we visited works out to about Rs.205625. This is ten times the amount of capital investment required to create a job in the poha mill. The machinery used in the rice mill was imported which contributed to high initial capital investment.
Tabla and Mridangam workshop:
After visiting rice mill, we went to see tabla and mridangam workshop. We saw two workshops. Tabla and mridangam are two of the most popular m u s i c a l instruments used in the Hindustani and Classical music respectively. O n e o f t h e workshops that we visited was a 3rd. generation of the family. The first facility had two employees and the second one had 5 people for day to day operation.
Figure 6: Economic determinant for Tabla making
As we can see from figure 6, the raw material comes from external environment and the finished product also goes to external market/environment.
The membrane for drum is made from goat skin and is bought from markets in Gujarat and Sholapur (Dilip Narayankar). The wood required for the drum is obtained from Gujarat and Delhi. The ink required for ‘Sur’ or Shyahi or the Black made up of carbon. Sur has to be rubbed by black stone for 8 hrs. It is bought from Surat in Gujarat. The body metal for the Duggi (of Tabla) is bought from Mumbai.
Cost of Goat Skin = Rs150- 200 per piece Cost of Ink = Rs 250/kg
Cost of body metal = Rs 650/kg
The finished instrument is then sold in Mumbai and Pune. The workers were telling that the business was growing and there was an increased demand these days.
Ganpati idol making factory:
After visiting. Tabla and Mridangam workshop, we went to see Ganpatai idol making in a nearby workshop. Ganapati idols were being made using plaster of paris (POP). They also mentioned that some idols are made using “shaadu maati”, clay. Typically 5000-6000 idols are made for the season. Maximum of 5 - 6 feet idols are made. They had about 10 -15 workers.
Figure 7: Economic determinant for Ganpati making factory
As we can see from figure 7, the raw material comes from external environment and the finished product also goes to external market/environment. Some finished products are also consumed locally.

industry. In a labour intensive setup, people can be trained and skills can be developed in an informal way which will help people to find employment. In the case of capital intensive industries, one needs specialized training which itself would incur a substantial expenditure and which cannot be done in an informal way as it requires training using machines.
Therefore, a policy which promotes labour intensive small scale enterprises which can also train and enhance people’s skills can go a long way in providing people employment in a labour surplus nation like India. This would a paradigm where human development is the priority rather than a capitalist paradigm where profit is the sole motivation
Ganesh idol making enterprise which is a similar case to that of wooden toy making requires an initial capital investment of Rs.95428. Ganesh idol making is a labour intensive process which has traditionally been a source of employment for rural people in India.
Toy Making Unit:
The toy making unit was a very interesting visit. The production was confined to a single room of 400 square feet. The owner was a very old person who told us that due to the new generation's interest in video games these wooden toys are very low in demand.
As making wooden toys involved wood turning mechanism to shape the wood pieces, all the toys made form it had circular shape. The interesting part was the painting. Coloured lac was used for colouring the turning wood. Once the colouring is done certain leaves which had oily texture were rubbed on the wood. The oil in leaves used to give a varnish kind of smoothness and shine to the surface of wooden toy. As everything was done when the wooden toy was rotating at high speed the quality of finished product was nice.
The assembly for wood turning was very simple. There was a 2hp motor which, through the pulleys, rotated the wood piece. Workplace involved only a single person and was very primitive. There seems to be no arrangement for safety as motor was installed very near to the storage area. That coupled with the primitive electrical connection to motor and lots of wood around posed a real danger of fire.

In the case of a wooden toy making rural enterprise, the capital investment to create one job was about Rs.27,000 without including the cost of land. Industries similar to toy making which are traditional small enterprises are under threat from escalating land prices where including land prices in the initial capital investment would render it unviable. The initial capital investment which includes the price of land is about Rs.1,27,000.
RCC Pipe Making Factory:
RCC Pipe making unit was not functional at the time of visit though we were able to see the machinery and moulds used in making the RCC pipes. The most interesting machinery was the use of a Truck's Gearbox used with an electric motor to get a variable speed drive. It was a pure innovation as it served the purpose of different RPM outputs without the use of a costly motor.
Figure 8 : RCC Pipe making from development point of view
RCC pipes, as the name suggest, make use of iron mesh embedded in concrete for strength.
Once the moulds are placed together sandwiching the mesh the concrete is pumped. The interesting part is that the final mould is rotated at high speed to let concrete spread evenly.
This rotation is done at different RPM at different times and the duration is different for different size of pipes.
Once the Rotation is done the mould is left to set for some time. This is done to let concrete set. Once the concrete is set enough to be rolled, the moulds are opened and the piped is rolled towards the curing tank. The pipes remain in the curing tank for few days depending on the their demand and the size of pipe. After few days of curing the pipes are ready to be
transported.
Vinoba Bhave's birth place Gagode :
We ended our first day field visit by paying a short visit to village Dagode, which is birth place of Maharshi Vinoba Bhave. We also visited Vinobaji's ancestral house where he had spent the initial years of his life. We were informed about the ' Bhoodaan & Gramdaan Movement' which emphasizes on community ownership. Brief introduction about the
biography of Vinoba Bhave enlightened us towards the simple ways of life & the philosophy of community ownership.
Second Day Interaction with Rural Communes :
Rural Communes was established in 1976 and since then it has actively worked for the cause of tribals and landless peoples. The main thrust of Rural Communes is training and capacity building. It is also involved in natural resource management issues related with water, soil and forests. For example, watershed development work done by Rural Communes at
Shedoshi village has changed the face of village completely. Due to availability of water for most of the year people are now cultivating a range of vegetables and other crops which have helped them economically.
Other fields in which Rural Communes is active are sustainable energy sources, Food security through sustained agriculture, Appropriate Rural Technology development and creating awareness among people for home garden for medicinal plants.
Parle Biscuit Factory:
Figure 10 : Parle Biscuit Making Process
We visited Parle factory on 6th Oct morning. As it was a large scale factory the scene was totally different from the factories we visited on 5th October.
We were first taken to an auditorium where were given clear and strict instructions that we are not allowed to use mobile and cameras. We were shown a 15 minute animation movie which pretty much showed the complete process of biscuit and candy making.
We were then taken to a candy making area where the famous "Kachha Mango Bite" candies.
The process seemed fairly simple as follows -
Liquid glucose and sugar are heated to melt till 140 degrees.
Water and steam are then used to make glucose and sugar mixture uniform and the whole mix is then filter pressed.
Whole mix is cooked and then while blending the flavours are mixed.
The mixture is properly kneaded to get a uniform mix.
The kneaded mixture is then sent to tablet making machine where candies take their shape.
The candies are then sorted and wrapped for packing.
After candy making, we visited the biscuit making facility where Parle-G and Coffee biscuits were made in parallel conveyor belts.
Raw material like Flour, sugar, edible oil and milk are mixed and kneaded.
The kneaded mix is then moulded to get uncooked biscuits.
Biscuits are then baked in an oven over conveyor belt followed by cooling.
The biscuits are then wrapped and packed.
Visit to Shedoshi Village:
Collaboration of Indo- German Scheme, NABARD & Rural Communes undertook the project of watershed development in the village of Shedoshi. The project started in 1984 &
ended in September 1999. The hilly region was divided into 11 micro watersheds so that each one can be considered individually for development project. The total cost of the project is about Rs. 166,00,000. Villagers have collected Rs.1,31,000 as maintenance fund via
voluntary labour (Shramadan). Tribal people sacrifice their livelihood of the day in order to contribute towards the project in the form of voluntary labour. Landless people also
contribute for the project even though they are not directly benefitted from the project. So 302 landless families have also actively participated in the Shramadan process.
Before the implementation of the Watershed project Yashodatai Waman Wagh had taken initiative to address some problems of the village like drinking water, employment &
livelihood, migration, debt, etc. People were migrating for jobs & ignoring their health. First intervention was in the form of formation of Women's Group. Women group started to grow vegetables because of increased water availability for cultivation as a result of watershed project. Plantation of Cashew nuts, Mango trees was done with the initiative of RC to encourage horticulture.
Watershed project covered the area from hill top to valley through various interventions like earthen dam, concrete dams, check dams, contour trenches, etc. Under the project a storage tank was constructed on the hill top which served as a source of irrigation during the rabbi season for the second crop. On the slope of the hill several contour trenches were dig in order to conserve the soil & water flowing.
After completion of project villagers have been applying for various government schemes.
For upliftment of society only watershed development is not enough it needs social &
Vertical Shaft Brick Kiln:
Final visit place for the field visit was the Vertical Shaft Brick Kiln (VSBK) run by Waman Bhau in Shedashi Khadki. VSBK is the joint venture of Centre for Technology Alternatives for Rural Areas (CTARA), Indian Institute of Technology, Bombay & Rural Communes, an NGO based in Narangi. This type of kilns are very rarely tried in India whereas this kiln type is quite popular in China as well as some parts of India like Uttar Pradesh & some parts of Maharashtra like Beed district. Main goal of the project was to help the local tribal
community. Main inhabitants of the area Katkari tribe whose traditional occupation was brick making & as construction labours.
The VSBK method of brick making is more efficient in terms of energy consumption &
hence less polluting. Main fuel source for VSBK is cow dung which is easily available, whereas main fuel for traditional process is coal. Brick making using VSBK is a continuous process whereas traditionally it is a batch process which is goes for a month & 40,000 to 50,000 bricks are produced. VSBK produces around 2,400 bricks in a day, so around 72,000 to 75,000 bricks in a month. Hence in terms of production & energy efficiency it is better than traditional brick making. It also requires less area for set up because of its vertical structure.
Mixture for making bricks is prepared by mixing soil & fly ash, then it is moulded & dried.
Sun dried green bricks are then put in the VSBK for baking. Vertical structure of the shaft makes it easier to operate as one just needs to put the bricks from upper opening of the shaft
the bricks plays important role in uniform baking of the bricks. Bricks are kept in the VSBK in units of six layers & each unit requires about 4 hours of baking. Trolley mechanism supported by the jack screw is used in the VSBK to move the bricks vertically within the shaft & to take the ready bricks out of the shaft. Heat distribution is also uniform in case of VSBK as main fire is lit up in the middle of the shaft so that, bricks at the lower end which are already baked & ready.
Many employees are Katkaris who need special training while handling the bricks to avoid the losses due to breakage. These bricks need careful handling & Katkari workers are provided the special training to work on VSBK.
Brick making is huge industry worth of Rs. 50,000 Crores, which is bigger than another important industry of air conditioning & refrigeration. Hence the industry needs attention from researchers & academic community.
Conclusion:
The two day field visit, was highly beneficial in understanding the actual beneficiaries for technology. It a was a good combination of various types and levels of industries and the guiding principles of each. The main thrust was empowerment and self-sustenance through technology and participation. Following is the conclusion based on various parameters we experienced:
Technology and Self-reliance:
The poha mill was stark in contrast to the Parle biscuit factory. The modern industrial manufacturing is capital intensive and uses technology that is imported. Most of the production is automated which results in decreased number of jobs. The factory runs on imported technology from Germany. The employees at the factory could not recall any instance when lesser automation prevailed at the facility. It was made known to us that certain machines have been made more efficient and advanced. They make much less noise and are more efficient compared to the machines used before them. In contrast, the poha mill runs on completely indigenous technology. The level of technology in use is not very
sophisticated (read western and imported technology). Except the belt drive (which is manufactured somewhere in Madhya Pradesh), all the other parts are fabricated locally.
The local people manage the poha mill completely and they are not dependent on ‘experts’ to maintain the plant. On the other hand, the Parle factory is completely automated which requires special training for employees who would be operating these machines.
Employment:
enough (In terms of jobs to locals or community development) to the local community to justify the amount of capital poured into building up the plant.
Resources:
Except milk and a few others, most of the raw material is brought to the facility from far off places. And going by the same logic, the local economy does not have so much demand for biscuits and confectionery from Parle’s factory. The products manufactured are sent to all parts of India for consumption. It was clear that this factory operated on the ‘economics of scale’ rationale where production in larger volumes with high capital investment results in cost advantages and improved efficiency in terms of use of resources. In the poha mill, local resources are processed locally.
Waste Recycling:
In the poha mill, the husk that is obtained after separating the rice is used as fuel for the furnace. Thus, the waste is recycled effectively unlike the biscuit factory which uses electricity produced predominantly from coal or nuclear energy. The externalities of the biscuit factory are much higher in terms of effect on environment compared to the poha mill.
Another aspect of the poha mill was that the nutrients between the husk and rice is used a fodder for cattle. The nutrient between the husk and the rice doesn’t go wasted and is used effectively.
Alienation and Modern Workplace:
The more modern and automated the industrial facility which is followed by increased
‘professionalization’ of the workplace, human beings become resources which need to be taken care to improve productivity. Alienation of the worker from his workplace becomes a fact and it could be felt in the biscuit factory. Workers in the biscuit factory were working like machines involved in excessively repetitive tasks. On the other hand, even though the workers in poha mill also had to endure ‘repetition’, the condition perceived in poha mill was different. Human beings were in constant conversation with other and each relied on the other to complete their tasks. They were in constant conversation and there was an implicit feeling of ‘recognition of the human in the other’ in the poha mill. Although the poha mill might not pay as much as a biscuit factory and also looks decrepit and old, the work environment was healthier from a psychological perspective.
Rural Enterprises: On the brink
Small enterprises like poha and rice mill are struggling to remain economically viable due to a number of reasons. Multi-national companies which operate on much larger scale are able to offer similar products at cheaper prices and have flooded the local market. In order to sustain economically and also employ local people, small enterprises have been dependent on subsidies from government on tax rebates and electricity.
People in the rural and semi-rural places like Pen believe that there has been a transformation in the way people perceive life with the gradual withering away of the traditional economy.
They don’t foresee a future for small enterprises like the poha mill in pen which is gradually being transformed from being predominantly rural to an urban place where more people turn away from agriculture due to its diminishing scale of return. With the turn away from
agriculture, people who were self-reliant (in terms of growing their paddy and getting their poha from poha mill) have started depending on the market for their basic needs. There is a gradual process of people giving up their direct relationship with nature and market has become the mediator between man and nature. The people who we spoke to were feeling that this process is inevitable.
The changing life style was termed as one of the prime reasons for lack of market for toys manufactured by traditional means. With kids taking to video games and television in India, the demand for traditionally manufactured toys has gone down. The traditional toy making enterprises feel that it is vital to ‘remember’ and memory of their ancestral craft forms an important part of their identity. The case is quite similar with tabla makers who felt that electronic musical equipments which can mimic any traditional instrument as the major source of concern for them.
The ‘Ganpati’ murti making industry in India is quite substantial in that it provides
