Long-lasting Sealant Made from Waste Invented by a Filipino Farmer’s Son, Won a National Award 4

Over 2,000 aspiring inventors from 28 nations and regions applied for the international design award this year.

The annual design engineering competition recognizes, encourages, and inspires the next generation of innovators.

Pili Seal: Sustainable aircraft sealant. Philippines 2021 James Dyson Award winner.

Mark Kennedy Bantugon of the Philippines received a national award for his invention of the Pili Seal. During his internship at an aviation company, the Philippine State College of Aeronautics student developed the sustainable, two-component sealant after learning that a polysulfide-based sealant was industry standard.

Though effective, polysulfide-based products can be hazardous and harmful to individuals who use them.

Bantugon decided to use the waste of the pili tree, also known as spent resin, based on his education and experiences as a farmer’s kid. From there, he worked hard and went through 38 sealant compositions before settling on the best one.

Pili Seal has been subjected to 20 different property testing, including physical, chemical, mechanical, thermal, and rheological examinations.

Bantugon aims to continue researching and optimizing the sealant so that it can be utilized in various industries such as land and water transportation, constructions, structures, wood, and metal sheet roof applications. As a result, Filipino farmers may resort to resin waste as a source of income.

“I was struck by the lack of options to effective and sustainably-produced sealants in the aviation industry and thought there should be a way around. Pili Seal pioneers the study of upcycling waste materials for production of aviation sealant. Through my invention, I hope to inject a new perspective that beneficial and sustainable usage can be found from waste materials. I hope this will inspire greater innovation in global aviation, while empowering the livelihoods of local Filipino farmers through new streams of income,”

Bantugon said.

Bantugon’s idea outperformed ReConnect, a portable and compact gadget that restores internet connectivity in disaster-stricken locations. The third runner-up was a gadget called Non-Invasive Bacteria Detector on Wounds, which uses an electrochemical gas sensor to detect infections in wounds.

The international stage of the James Dyson Award 2021 is set to take place on October 13, 2021.
