Project Information
Title: Eco-friendly and Bio-degradable Menstrual Pads
Subject: Medicine and Health
Subcategory: Personal Hygiene
Grade level: Middle School - Grades 7-9
Academic Level: Ordinary
Project Type: Building / Engineering
Cost: Low
Awards: Global Finalist
Affiliation: Google Science Fair
Year: 2016
Materials: Dry leaves, cotton, jute, coconut husk, hay, and wood shavings, arrowroot mixture
Concepts: Absorbency
Description: The aim of this project was to make a menstrual pad that would last six hours, provide comfort and quality, but degrade within a short period of time. Due to recent concerns regarding diseases caused by dioxins present in pads, the objective of this project was also to make chemical-free pads. This involved the use of natural absorbents instead of chemical polymers, and a casing that wouldn’t be bleached. Six different materials that could be used as absorbents were tested including dry leaves, cotton, jute, coconut husk, hay, and wood shavings.

Menstrual Pads

A sanitary napkin, sanitary towel, sanitary pad, menstrual pad, or pad is an absorbent item worn in the underwear by women and girls who are menstruating, bleeding after giving birth, recovering from gynecologic surgery, experiencing a miscarriage or abortion, or in any other situation where it is necessary to absorb a flow of blood from the vagina.

A menstrual pad is a type of feminine hygiene product that is worn externally, unlike tampons and menstrual cups which are worn inside the vagina. The frequency a woman will need to change her pad will vary depending on whether her menstrual flow is heavy or light.

Menstrual pads are made from a range of materials, differing depending on style, country of origin, and brand. US brands include Kotex, Always, Equate, and Stayfree. Lil-lets are available in several other English-speaking countries.

These pads are not to be confused with generally higher absorbency incontinence pads, which are worn by people who have urinary incontinence problems or experience stress incontinence. Although menstrual pads are not made for this use, some people use them for this purpose.

There are disposable pads and reusable cloth pads that are environmentally friendly and do not contribute to landfill as they are reusable and do not come in or contain plastic packaging.
