Round Two: Banana-fiber sanitary pads need curves and wings

A plan to manufacture sanitary pads made from banana fiber in Rwanda hit a snag in field tests: The Rwandan women were skeptical of the pads’ quality. They prefer pads that look and feel like the more expensive imported pads than the locally made ones meant to replace them.

That was the lesson from field tests of a prototype pad manufacturing machine that we reported on earlier. Design changes are underway.

The pads are an early attempt to remove a little-known stumbling block to economic development in Rwanda and other impoverished countries. Some of the world’s poorest countries do not produce their own pads. Instead, they rely on expensive imports.

Women who don’t have them may stay home rather than risk embarrassment in public, skipping about 50 work and school days each year. When they must go out, some women have resorted to using rags or even bark and mud.

Elizabeth Scharpf is working to provide financing for micro-businesses in sanitary pad production. Her organization, Sustainable Health Enterprises, specializes in developing market-based solutions to developing world problems.

Scharpf ‘s plan called for a machine that local workshops could produce and sell to women who wanted to establish a home business making pads. Katherine Smyth, a recent MIT graduate, took on the challenge. She developed a table-sized prototype that she calls a Komera.

Today, the Komera prototype consists of fancy plastics, metals, and parts that are easily found in the United States. Its final incarnation, Smyth plans to make it from simpler materials easily sourced in Rwanda. It should cost about $1000.

The first pads that rolled out of a Komera were rectangular and bulkier than the trim designs and contoured edges of commercial pads. Smyth and her team are tweaking the machine to produce pads that resemble the ones that come out of a box. She also plans to add wings to attach the pads to underwear, she said. New tests should begin in the coming months.
