This paper discusses how to make a diaper made with biodegradable materials. With the population increasing, pollution has become more prevalent in our current society, especially with waste that cannot be broken down and composted. Other companies that make diapers do not make use of environmentally friendly materials. Instead, they use gels and cloths that are not able to decompose. We used kapok fiber and bamboo cloth to tackle this problem and create environmentally safe and fully biodegradable diapers. We tested the diaper prototype dubbed the “Kaboo Diaper” using the rewet and absorbency test. The absorbency test showed that the diaper absorbed 323g of simulated urine. The rewet test showed that the diaper picked up 24g of water over time, passing industry standards. Showing the diapers to mothers contacted by the Health and Sanitation unit of Brgy. Oranbo deemed the prototype ready to use.
