India has huge natural bamboo stocks that have been an integral part of Indian culture for many millennia. Bamboo in many ways is the mainstay of the rural Indian economy, sparking considerable social and ecological spin-offs. In the early part of the century, large tracts of bamboo occurred in many parts of the country but were treated by forestry sector (which was then cast in a production forestry mode) as a weed of little economic value and were used mostly by the rural communities for crafts, making implements and as housing material. It was the discovery of bamboo as a source of long-fibre by the Forest Research Institute in Dehradun that started the process of using bamboo in a variety of industrial applications, so far unexplored, with several paper mills and rayon mills being set up. But in the absence of a clear policy of husbanding of the resource there was rapid degradation and decimation of the resource in much of the country. Bamboo resources plummeted so alarmingly that at present the resource is limited to few pockets in the country. Two-thirds of the bamboo in the country is restricted to the North-Eastern Region (NER) while the remaining one-third is spread across the country.

But there is hope for the resurgence of bamboo, and this is based on evidence of significant new and contemporary economic opportunities that have emerged over the past decade. A bamboo revolution that holds the potential of reversing economic downturns and ensuring profitability, is very much possible.  Bamboo is an untapped avenue of economic growth and a burgeoning bamboo sector can rope in prosperity, profits, and sustainable livelihoods.

 Despite the severe degradation of the resource in the past, India still has a considerable growing stock of bamboo, and comparative annual harvest figures[1] still place India at the top of the global league. It is important to realize the considerable latent potential that bamboo has to contribute to economic growth, poverty alleviation, generating employment, rehabilitating vast tracts of degraded land generated due to past agricultural and industrial practices and policies, and revitalizing the social, economic and ecological well-being of rural economies.

 In line with this, goals should be aimed to focus on recovering the resource lost to the rural poor, as it has been a natural capital that has helped them to keep their economies afloat even in times of significant cash crunches. Attempts should be made to replenish bamboo stocks, make it economically beneficial to rural communities in a way that it provides them opportunities to earn a sustainable income and improve their standard of living. Efforts should also be made to increase the economic opportunity from the use of bamboo as an industrial raw material, to raise employment opportunities (especially for the educated and unemployed rural youth), and to rehabilitate the degraded lands across the country (making available and productive a natural resource which is increasingly becoming scarce and expensive).

  DEMAND DRIVEN SCENARIOS

 As per the statistics available from the FAO, approximately 678,000 cubic meters of round wood logs were imported into India in 1997. The import quantity has gone up since then. According to the latest estimates available, the volume of logs imported was about 1.4 million cubic meters in 1998-1999. It is estimated that this figure would be around 2.0 million cubic meters for 1999-2000.

 The sawn wood and panels import, which was about 57,000 cubic meters, also would have gone up considerably, though no reliable figures are available. Although timber is normally obtained from government forests, community lands and private lands, the national timber production statistics report only timber extracted from government forests. These statistics indicate an increase in demand for wood even as there has been a decrease in the production of timber from government forests. The recorded production of timber accounts for less than half of the industrial wood demand in India.

 

 Each of the value-added industries that have been identified in the table above would pursue a growth rate based on the demand for the products. The demand, in turn, would be based on the increased acceptability of the products in the international and domestic markets. The demand will be a function of:

• 1. Increase in the cost of substitute materials such as wood, steel and other building materials
• 2. Recognition of the high durability of bamboo-based materials
• 3. Community appreciation of bamboo as a sustainable livelihood crop and their increased acceptance of the same

4. Mass usage of bamboo in government projects like housing and roads

5. Acceptance of bamboo as a material for flooring and furniture making as well as a food item among the higher income groups

From the year 2010 to 2015, the growth in the bamboo industry should be starting to acquire a definite contour. While the focus in the foundation years was on the industries that were already using bamboo as a raw material – the paper industry and handicrafts – and setting up the infrastructure and investment in new industries, the emphasis in this stage will be on the shift from lower value-added applications to higher value-added ones – bamboo board, flooring and bamboo shoot for example. This stage will mark the transformation of bamboo from a mere forest produce to a commercial commodity.

Bamboo can find a medley of new application areas that have a tremendous market opportunity, potential as well as value addition. Bamboo products could find application in high absorption and mass consumption industries like roads and housing because of its attributes of high strength and low weight. The use for bamboo grids for reinforcement of roads is an innovative application, which has not been used elsewhere in the world. Bamboo makes for excellent construction material and Ecuador has used bamboo extensively and successfully in construction of homes. Bamboo offers a low-cost but strong housing solution. Bamboo briquettes are also a new application as far as India is concerned, but they are widely used in other bamboo growing countries. Another market that could be tapped is the niche market of bamboo shoots. It is a highly popular delicacy across the world and its consumption in India needs to be promoted. Bamboo’s capacity for regeneration makes it an eminently suitable replacement for wood and it is perhaps why bamboo is referred to as “tomorrow’s timber.”

 The last 15 years has seen a mushrooming of the variety of commercially available bamboo products. As well as traditional products, there is now successful commercial production of bamboo flooring, laminated furniture, building panels (similar to timber based plywood, chipboard or MDF), high quality yarn and fabrics, activated carbon, bamboo extracts and so forth. These are no longer novelty items but are successfully competing in the marketplace and gaining market share. These recent developments have created new opportunities for leveraging bamboo as a basis for rural industrialization and poverty reduction. In particular, the emergence of new higher added-value processing increases the sector’s potential economic impact, especially in poor rural communities, compared to traditional lower value processing industries.

Unfortunately not all of the bamboo plant can be used to such effect. Premium processing needs premium parts of the bamboo (typically the middle lower part of large culms). So modern bamboo industries need a mix of different businesses producing a variety of products, with premium bamboo parts going to premium uses (e.g. flooring, laminated furniture), mid quality parts (e.g. upper mid section) going to medium value added processing (e.g. blinds, mats, chopsticks) and the leftovers, sawdust and other processing ‘waste’ being used in the bulk processing industries such as paper, charcoal or chipboard.

But the use of bamboo in these industries would be possible only if it makes commercial sense. Unless it makes business sense to replace existing materials with bamboo, the crossover would not be possible. To make bamboo and its products economically viable, the intervention of a number of facilitators and stakeholders is required. 

From a production perspective, it is possible to divide the sector into distinct sub sectors, each of which can exist on a standalone basis or in combination with the others:

1. Handicrafts: characterized by high levels of semi-skilled and skilled manual processing of relatively small volumes of bamboo culms.

2. Bamboo shoots: essentially a high value agricultural crop that can either be grown primarily for shoots or in parallel with the production of culms.

3. Industrial processing: semi-mechanized and mechanized processing of comparatively large volumes of bamboo culms. Industrial processing industries can be further divided according to the value of the processing and grade of material used:

i. Premium processing (e.g. flooring, laminated furniture, Ply board)

ii. Medium value processing (e.g. Incense sticks, Blinds)

iii. Low value and bulk processing (e.g. charcoal, paper & pulp)

4. Unprocessed culms: supplied to the local construction industry or used for domestic household applications.

Laminated bamboo furniture is a modern invention but has already become popular in many countries. It is produced from molded bamboo components and to the uninitiated eye the furniture is unrecognizable as having been produced from bamboo. A huge range of furniture can be produced, such as table and chairs, bookshelves, beds, cabinets and recliners. The furniture is durable, practical and has a modern appearance and in recent years elegant designs have been produced in China and Japan.

The laminated bamboo furniture unit is a relatively large-scale venture requiring start-up capital and a number of experienced personnel. By innovating new designs and seeking out new markets the unit will be able to develop rapidly and there are significant opportunities to open up exporting markets for laminated bamboo furniture in more affluent countries. The unit can easily be established at the community level, ideally as a cooperative venture. In view of the scale of investment required it might be preferable to establish the unit with the assistance of state agencies or NGOs to ensure the venture is successful and the community is the true beneficiaries.

Drawing the profile
In Furniture construction, full-scale drawings are utilized to enable one to pick measurements off the drawings while actual construction is on. For this purpose, the design is drawn full scale.

Bending with Heat
Following the practice of the cane furniture manufacturers of the North East, blow lamps were used to apply focused heat on to the poles and force bend it on a Wooden Horse (Mould). Basically the mould or horse is made out of solid wood. While one beam is perpendicular to the ground, there are two support beams parallel to the ground. The artisan makes a notch in the perpendicular and after hitching the bamboo in the notch, applies direct heat through the blowlamp. The notch is basically locking the bamboo in place and manual pressure is applied towards gravity to bend the heated pole. From time to time, a wet cloth is run onto the heated area of the pole so that the bend cools and solidifies. The pole is taken off the horse regularly, and measured on a drawing /profile to check for accuracy.
Though tedious and labor intensive, the method is able to achieve almost 100% accuracy. There is loss of the surface thickness as the excessive heat scorches the bamboo and the scraping the black skin reduces the thickness of the pole. However if totally solid bamboo is used, the loss of surface has a negligible effect on the strength of the bamboo.

Preparing the raw material
The outermost skin is scraped off to bring out the smooth luster and even colour of the bamboo. In the process, the knots on the internodes are also flattened /evened out.

For straight sections, the scraping is done before sizing. For sections that are to be bent into profiles, the bending is carried out before.

After the correct profile is achieved, the bamboo is then scraped to remove the outermost skin and the burnt marks.

Knot removing and planning surface
Various methods can be applied for surface finishing of bamboo. For knot removal, planer can be used to scrape the knots. The Team also explored using rudimentary sanding machine, and found it to be extremely useful in scraping the outer surface of the bamboo. This method reduces the drudgery of manual hand shaving.

Joinery and Assembly techniques
Most of the joinery used in Bamboo furniture is same as those used for wooden furniture. Simple joints like tendon -mortise joints work in totally solid bamboo. Plugs are inserted at hollow ends.

The furniture is an assembled frame-by-frame using carpenter vice. Bamboo dowels are used diagonally to seal joints. Before inserting the joints, industrial adhesive is used to add strength to the joinery.

Laminated blank making
Prepared sections of bamboo wood are coated with glue and then placed together in jigs to form the sub-sections of the furniture. Straight sub-sections can be pressed together in a standard hot-pressing machine, but curved sections require specially shaped jigs and are pressed by tightening bolts holdings the jig-forming elements together. They are then placed in a heated chamber for curing.

Finishing the product
At final assembly, the product is sanded before applying the termite resistant coating and melamine. Finishing involves the following stages, all designed to produce a high quality, uniform surface finish: Bleaching, prestaining, staining and coloring, wash coating, filling sealing or wash coating, glazing, top coating, rubbing, polishing and cleaning. Addition of upholstery and other fitting completes the furniture.

Market-Size: The consumption of wood other than plywood for making furniture is estimated at 3.36 million cubic meters in 2005 and set to rise to 4.62 million cubic meters by 2010. Bamboo as a substitute for wood to make furniture is expected to grow up to US$224 million by 2010. A range of furniture for school, office, showroom and home is made from bamboo. Bent-laminate furniture from bamboo is currently under prototyping. Consistent supply of processed bamboo is the key to the growth and development of this industry .

Bamboo is an important means for generating income and improving the nutritional status of over 2 billion poor and disadvantaged people. It also provides the resource base for expanding Small and Medium Enterprise sector, providing employment and income generating opportunities to alleviate poverty. As such it constitutes an excellent entry point for local poverty alleviation initiatives.

Bamboo benefits rural-urban communities because it, (a) lends itself to agricultural approaches, (b) can be grown on non-agricultural land with annual harvests, (c) is easily processed by simple tools because it splits linearly, (d) bamboo based industrial development benefits the communities through its demand for human resources for growing, harvesting, transportation and processing of bamboo, (e) bamboo growth also works for land protection, soil quality improvements including improved water holding capacity, higher water capture and recharge benefiting agriculture and food security.

Bamboo remains an untapped avenue of economic growth in India. Its premise is that if the bamboo industry is pulled from its current status of a peripheral industry and pushed centre stage to being a prominent and profitable one it can successfully reverse economic downturns and bring an about-turn in the economic fortunes of the country. This would be particularly true for the Central Gondwana regions (CGR, Madhya Pradesh, Chhattisgarh, Western Uttar Pradesh) of the country where the resource is abundant and could be sustainably harvested in the years to come because of its amazingly quick propagation.

With its inherent properties, bamboo combines the best of forestry and agriculture. It holds the promise of rejuvenating watersheds and degraded lands, fortifying the country’s ecological security. What would distinguish growth in this sector is that it would directly benefit large sections of the rural poor, as they could be involved in the plantations, harvesting and primary processing bamboo units. The long-term relationship with this sector would help the economically disadvantaged sections escape the debilitating poverty trap. The development of the bamboo sector could follow in the footsteps of the dairy sector whose miraculous makeover has enabled 10.5 million farmer families earn a supplementary income of Rs 1,800 per month. This industry’s growth model has been successfully replicated in 22 states in the country and it spells hope for the bamboo sector.

The blueprint envisaged in meticulous detail here for the bamboo industry projects a growth in the sector from Rs 65 billion in 2003-2007 to Rs 240 billion in 2013-2017; a growth that would could even overtake that of the biggest bamboo economy of the world, China. The overarching model also projects an employment opportunity of 1.67 million in 2003-2007 that would climb sharply to 11 million in 2017. For example, the NER, whose economies have been trailing behind, the estimates are the bamboo sector can take their gross domestic product from Rs 230 billion in 2003 to Rs 290 billion in 2007 that would translate into a growth rate of 5 per cent. The bamboo industry would have a potential of employing a total of 1.88 million people in this region by 2017.

                        KEY CONCLUSIONS

§         The global market for bamboo products USD 7 billion + per annum*

§         Bamboo based enterprises can prove to be the key in rural economic development and mass employment creation

§         Governments and local administration must provide sustained and consistent support if the sector is to develop

§         The future of global bamboo markets looks strong, driven by growing demand for sustainable wood-replacement products

§         The commercialization of recent technological innovations has created significant new market opportunities for floor tiles, laminated furniture, panels and activated carbon.

§         New, higher value added processing greatly increases the potential for poor economic development compared to traditional lower value enterprises. For example, every tonne of bamboo used for producing bamboo boards has 5 times more pro-poor financial impact than if used for paper.

§         Markets in US, EU, Australia and Japan present significant opportunities for several high value products

§         The competitiveness of future bamboo enterprises will be largely driven by ‘value added utilization’ of the entire bamboo plant.
