    Obtención de un material biodegradable impermeable para su utilización en vajilla desechable
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2024-02) Hurtado Salazar, Nelson Enrique; Molina Guerrero, Javier Alexander; López Velástegui, Jorge Enrique
    In recent years, industrialized nations have seen a significant increase in the production of household waste, likewise, the growing environmental awareness and the demand for sustainable alternatives have generated the need to develop biodegradable and waterproof materials that allow for environmentally friendly elements. A waterproof biodegradable material was obtained for use in disposable tableware, under an experimental methodology and a series of tests were carried out; hardness, flexure and impact, and waterproof and degradability testing, comprehensively addressing the challenges associated with obtaining this material; using the necessary international and national standards to ensure that the result is a valid option, which meets the requirements and parameters necessary to ensure people's food safety. In addition, a simulation of the behavior of the plate was carried out in a specific software, determining its maximum deformation, placing the maximum force obtained from the tests and indicating the fixed clamping conditions so that the plate does not present any displacement and achieve optimal results. The results allow us to assert that sugarcane bagasse has a lower resistance; These values were similar for the bending, impact and hardness test without the application of a waterproof film. Last but not least, for the issue of impermeability, the food grade film was applied where it yielded similar results for the final product, with rice husk being the best biodegradable and waterproof material.

    Diseño y construcción de una máquina para producir platos con material biodegradable para el Laboratorio de Materiales de la FICM-UTA
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2023-03) Guamanquispe Salas, Paúl Aníbal; Pardo Domínguez, Alex Fabricio; López Velástegui, Jorge Enrique
    From an environmental protection point of view, it makes sense to stop using singleuse containers made of polluting plastics and start using biodegradable and compostable products. Biodegradable and compostable tableware is much more environmentally friendly compared to disposable plastic tableware. A biodegradable material decomposes much faster than plastic, thus acting as a solution to a major issue today. Technical and technological know-how was provided to design and build a machine to produce dishes with biodegradable material. Research on biodegradable materials and how it can be transformed into a single-use container was carried out. Afterwards, the design was made considering several proposals of other examples and following design parameters, as well as standards related to the subject. The prototype was built and finally the tests were carried out with a proposed raw material, which is based on wheat bran. The biodegradable plates were manufactured by programming the prototype at a temperature in the matrices of 140 degrees Celsius, a pressure of 7 bars and within one minute a biodegradable plate of approximately 70 grams was obtained. Once the biodegradable plate was achieved, some tests were carried out to get an idea of its mechanical properties, especially its resistance to bending.
