The impact of using plastic straws has been a long controversial discussion in terms of
environmental aspects. This study aims to develop a straw extrusion machine that uses
dough-type corn mixture as the raw material to address the environmental risks caused by
producing and using plastic straws. This project used 304 food-grade stainless steel
surrounded with acrylic boas will be used to support the weight of the motor, auger,
extruder, and UV. The machine undergoes multiple testing to show its effectiveness of the
machine in terms of how many mixtures can be put into the machine and how many straws
it can produce; the prototype was able to extrude and mold up to 415 grams of the mixture
in 20 minutes based on the tests conducted. The researchers conducted two (2) phases to
test the capability of the prototype, the project demonstration, and the evaluation. The
machine was evaluated based on the seven (7) criteria included in the Technological
University of the Philippines evaluation instrument, functionality, aesthetic, workability,
durability, economy, safety, and salability and gained a mean score of 4.52 with a
descriptive rating of excellent. Furthermore, it is highly recommended to improve the
functionality and efficiency of the prototype.
