Towards Large Scale Dissemination of
Sustainable Building Materials and Technologies
Shrashtant Patara
There
is an acute housing shortage in India coupled with a perceptible
shift towards energy intensive materials like cement, steel,
aluminum and PVC. The inevitable growth of population and societal
expectations over the next few decades will require significant
augmentation in the supply of building materials. The construction
sector also accounts for 22% of CO2 emissions
in the country and already consumes a disproportionately large share
of non-renewable energy. Future generations will face
insurmountable environmental problems unless technological course
corrections are made. “Sustainable building materials and
technologies” are without doubt the road along which we, as a
nation and perhaps the whole world, must travel but it is not easy
to define our destination in terms of tangible results, particularly
for the poor. Development Alternatives believes that sustainable
building materials and technologies must ultimately result in over
30 million houses being built and hundreds of thousands of jobs
being created without destroying the environment. Given the
futility of the state trying to build these houses and employing
more people, latent demand in this sector can only be activated if
building materials are made more cost-effective and easily available
through an efficient delivery system.
Our approach
In its Swiss Agency for Development and
Cooperation (SDC) sponsored Building Materials Programme BMP), DA’s
approach presupposes the need for continuous growth in this sector,
without which none of the above results can be achieved.
Augmentation of supply is based on sustainable production systems
that integrate:
q |
Issues affecting local availability
of resources and their potential for renewability |
q |
Basic human needs and equitable
access to resources |
q |
Resource efficiency and material
intensity of production |
q |
Factors affecting scale, labour
efficiency and material movement. |
The BMP is being implemented by DA and
its partners at both local and national levels with support from
SKAT - the Swiss Centre for Development Cooperation in Technology
and Management. In order to learn from the experience of resource
management and institutional support mechanisms in a less developed
market, the Bundelkhand region in central India has been selected
for pilot introduction of technologies. Building upon previous
work, a much larger geographical canvas is being used to explore
mass marketing systems for Micro Concrete Roofing technology and
technology promoters have been engaged to put Compressed Earth Block
technology on a commercial fast track. All of these initiatives are
complementary in nature and will ultimately lead to the development
of technology packages and management systems for large scale
decentralized delivery of building materials.
Technologies Selected
Technology selection is the first
milestone that needs to be crossed before sustainable technology
packages can be developed and disseminated. It is constrained by
the limitations of desk research and can at best be a sound
analytical assessment of what products and technologies might be
suitable in a region. However, our experience has shown that if the
selection process is based on a serious understanding of people’s
needs, material resources, energy, skill availability and competing
products in the region, the likelihood of technologies being
accepted in the area is quite high. The specific technologies
selected in 1995 in the DA-SDC BMP were :
q |
Compressed Earth Blocks |
q |
Concrete Blocks |
q |
Vertical Shaft Brick Kilns |
q |
Ferrocement Roofing Channels |
q |
Micro Concrete Roofing |
Large Scale Dissemination Strategy
Elements of the approach described above
and the strong desire to maximise impact have been used by the
project team to weave a coherent large scale dissemination strategy
that has, while evolving continuously, stood up to logical scrutiny
over the past three years.
The first phase of the dissemination
strategy is to establish technical feasibility. Each technology is
adapted to achieve initial techno-economic viability and enviro-social
soundness. On the basis of feedback received from trials, potential
benefits to the user, the entrepreneur and the environment are
maximized. The elements of this phase consist of (see box for
detailed description):
q |
Technology appraisal |
q |
Acquisition of basic know-how |
q |
Prototype system development |
q |
Optimization with respect to people,
resource and environmental factors |
Decentralized production systems hold
the key to sustainable economic development. DA has therefore
placed great emphasis on designing profit making technology packages
for micro-enterprises. The technology packages consist of :
q |
Product profile, technical
specifications |
q |
Hardware-equipment, accessories,
etc. |
q |
Software-training manuals,
construction process |
q |
Marketing know-how and business
support services |
In the BMP, technical aspects are
integrated with human issues to define a complete technology
system. The selected technology packages go through a rigorous
Ecological, Social, Technological and Financial rating process in
order to assess impacts of these technologies in the region (see
separate article).
The feasibility phase is followed by a
dissemination preparation phase which involves:
q |
Lead enterprise development |
q |
Establishment of support service
providers |
q |
Establishing business networks |
The MCR technology package went through
an intensive dissemination preparation phase (April 1993 - Dec.
1997). Key aspects included technology positioning,
micro-enterprise development and an in-depth market study.
Technology positioning - MCR Leads the Way
Large scale dissemination can only be market based. In fact in a
sustainable commercial environment it must be market driven.
Each technology package is designed to
ensure that its product meets price specifications of the mass
market, which in India, has low levels of surplus cash for house
building. Durability and affordability or in other words, “Value
for Money”, are important criteria in positioning a technology.
Individual products are also analyzed
with reference to competing products to identify gaps within which
the product can rapidly establish its position. For example, early
market studies for MCR technology found a large gap between thatch
or country tile roofing and asbestos or G.I. sheets. The technology
adaptation team focused its efforts on meeting the cost
specifications of this niche i.e. a roof between Rs. 150 Rs. 200 per
square meter. This segment was broken into quite easily by the
first few producers and has accounted for the bulk of sales made in
rural areas and small towns.
Marketing through development of Micro-enterprises
Micro-enterprises are the most efficient
and sustainable way to deliver sustainable building materials on a
widespread scale at a rapid rate. The BMP has therefore focused its
efforts on the development of viable enterprise models.
Each technology package goes through a
“lead enterprise” stage in which the project team interacts closely
with entrepreneurs on technical, market and financial aspects to
formulate a replicable enterprise package. Lead enterprises are
also instrumental in establishing primary market acceptability of
the products and defining scope of other value adding services such
as roofing.
These activities lay the foundation for
market expansion in the large scale dissemination phase.
Market Potential
Identification of suitable regions and
assessment of market potential are vital steps in the technology
dissemination process. SDC and DA commissioned HOLTEC Consulting
Pvt. Ltd. part of the Holder bank Group, to conduct a study of MCR
Tiles in ten regions of India. it was confirmed that
commercialization of MCR production and marketing is a significant
business opportunity. The study predicted demand for 202 MCR
enterprise by the end of 1998. On a national scale this would
translate into 2500-3600 production units being established over the
next five years. Put together, they would be capable of installing
15 million sq. mt. of roofing worth 3 billion rupees every year.
A market potential study for Bundelkhand
based on census trends and likely shifts in product choice revealed
that out of an estimated 344000 new houses required between 1996 and
2000:
q |
15,480 will use brunt bricks fired
with VSBK technology |
q |
3,096 will use concrete blocks |
q |
1,720 will use compressed earth
blocks |
q |
11,696 will use MCR tiles |
q |
5,848 will use ferrocement roofing
channels |
Successful completion of the
dissemination preparation phase sets the stage for the large scale
dissemination phase, in which the major steps are Market
Development, Technology Liberation and finally Project
Disengagement.
Market development
In the initial stages of technology
promotion, success in marketing of MCR was designed through
decentralized initiatives; primarily micro enterprises that produced
and sold an average of 4000 - 5000 tiles per month with very little
promotional effort. Expanding upon their success, TARA Crete
Building Products demonstrated the impact that active market
development could have on latent demand in the Jhansi area. Their
operation is currently logging sales of approximately 12,000 tiles
per month and is still growing
The Project Resource Centre located at
TARAgram near Jhansi has developed the market for all its building
products: MCR tiles, FC roofing channels and concrete products.
This has been achieved by offering building solutions to house
owners, institutional users and district agencies which include a
package pf services; including design and construction. Such
initiatives have focused on rural and peri urban areas.
Market Expansion
The BMP is now engaged in creating
greater diversity in terms of product use, delivery mechanisms and
scales of marketing operations according to the nature of specific
markets and enterprise profiles and commercial technology
promoters. The scale of production is optimized according to the
specific business model.
The strategy for market expansion is
based on the evolution of the MCR technology package to meet the
needs of not only the micro-enterprise but larger scale marketing
operations as well. Our partners, COMTRUST have planned a 2000 tile
per factory for their high volume, high quality market in South
India, Vishwakarma Industries envisages a chain of outlets in Punjab
and TARA-BKF is franchising MCR production and sales in Bhopal and
Dehra Dun.
Looking Ahead Towards Liberation
Development Alternatives has attempted
to position all the building products-technology combinations within
a framework: the Market-Technology matrix (see Table). The
products which have high acceptability in the market are burnt
bricks and concrete products; both being produced at several levels
of technology which coexist in different regions in India. Micro
concrete roofing tiles have established market acceptability only in
limited reigns. The new products invariably use energy efficient
processes and new technologies. The design of the dissemination
strategy is highly dependent on the position of the product in the
Market-Technology Matrix. It defines the market conditions and
technology combinations selected for the Building Materials
Project. The MCR and CEB modules are based on technologies that
have achieved market acceptability in selected regions. The thrust
of technology promotion will be with Commercial Technology Promoters
in high potential regions and well developed markets. These include
Product Marketing Companies, Franchise Companies, Technology
Suppliers and Industrial Consultancy Organisations. The specific
role of New Technologies is that they offer high potential in less
developed markets for
q |
Augmenting Supply |
q |
Resource Efficiently |
q |
Energy and CO2 |
q |
Waste Utilization |
q |
Local Market Development |
The consolidation of a set of these
technologies will be achieved through the Bundelkhand module which
will identify and strengthen local initiatives through complimentary
set of Institutional Technology Promoters.
Development Alternatives has designed
the BMP in a manner that both substantive outputs are achieved and
pools of competence are built within a partner network which can, in
the future, manage the development and dissemination of other
sustainable building technology packages. q
Process
of Technology Development and Adaptation
The
objective is to develop technically and financially viable
technology packages that can be used by large number of
producers to manufacture and market affordable building
materials with improved performance that meet the aspirations
of the users.
The
technology packages are evolved through the following steps:
Technology appraisal:
The
technologies selected have to address a basic need or problem
in the region, against which performance specifications are
drawn up, for example: in walling CEB technology addresses a
niche between mud and local clamp bricks.
Acquisition of basic
know how:
This process involves establishing contact with experts and
other organsations, in-house capacity building and
assimilation of inputs on the product , product design,
production methods including machine selection along with
exposure to situations where the technology has been used
successfully.
Prototype Production
System Development:
It
involves optimization of design as per local conditions,
development of tools and accessories for improved production
and quality control requirements. Preliminary market research
is conducted through apilot test enterprise to identify user
expectations and market needs. Extensive training in
production is carried out for effective utilization to
popularize the building system.The production systems have to
be filed tested over period of time leading to further
improvements in equipment design involving addition of
accessories, tools, handling equipment and field testing
devices. This is a crucial step in order to get the
technology validated, improve production economics leading to
definition of a business profile and explore acceptability
among potential entrepreneurs.
Optimization with respect to Ecological Social Technological
Financial parameters:
Each technology package is reexamined with respect to these
parapets to improve performance of all parapets especially
social and financial. The degree of mechanization and level
of investment are also guided by the ESTF parameters so that
the capital and resource productivity is maximized. |
