Abstract
The Base of the Pyramid (BoP) refers to 4 - 4,5 billion people
in the world, who are living on less than a few dollars per day.
This majority of the world's population has a little resources
and is usually considered as a group with no purchasing
power and therefore is currently unserved and underserved
by current products and services. However, more than any
others, the low-income consumers are constantly and eagerly
looking for products that can improve their living and working
quality at an affordable price. Hence it is important today to
re-conceptualize and pay interested in the value-demanding
customers at the BoP. This is also considered as mission to
offer low-income people pathways to prosperity. By investing

The Base of the Pyramid (BoP) refers to 4 - 4,5 billion people

re-conceptualize and pay interested in the value-demanding
customers at the BoP. This is also considered as mission to
offer low-income people pathways to prosperity. By investing
in the 4-5 billion-person market, will engage in ways to do
well (make profit) and do good (improve humanity).

This Master's Degree Project is supported by the Innovation
Engineering group at the Department of Design Sciences, Lund
University, in collaboration with Blekinge Institute of Technology,
Sweden and Universidade Federal do Amazonas, Brazil.
An one-month fieldtrip has been taken place at the rural
communities near Manaus, Amazonas, focused on the target
of low-income people living in the Amazon region in order to
access closer to the daily life of local and clearly understand
the context of the people within.

Cassava is the third most important crop plant after rice
and maize in Asia, Africa and Latin America, and its flour is
a primary calorie source in tropical regions around the world.
In the Amazon region, Cassava roots are processed into a
type of flour called Farinha, which is extremely common and
is used as a basic staple food. The product also provides an
important income to huge numbers of households in the rural
areas.

Transforming cassava into flour is a long process which takes
a couple of days and basically includes six steps: Peeling, Washing,
Grinding, Drying, Sifting and Frying. Men usually engage
in machine operations for grinding, pressing and sifting, while
women and children are usually responsible for any manual
operations such as peeling, washing and frying. It has been
reported that peeling the roots by hand is a major problem
and takes 65% of the total time of the whole process. This
hard and tedious job has low productivity and high product
losses, and it is very time consuming and requires physical
labour in poor working conditions. However, machines for peeling
cassava are rare in this region due to the high cost of
available machines in the market, the scarcity of electricity,
and high cost of gas. How could this be improved?

My goal in this project was to design and develop a solution
for how a low cost product could satisfy the identified needs,
thinking about the importance of rural development and poverty
alleviation and how small scale productions can contribute
to households and livelihood security.

The result is a cassava peeling machine that improves working
conditions, increases the productivity, reduces product
losses, reduces time consumption and physical labour. Due to
the limit of electricity and high cost of gas, a pedal-powered
concept was chosen. The rotating drum efficiently maintains
the purpose of rubbing the cassava skin off, using high-tech
abrasive rollers with wire brushes. (Less)
