ABSTRACT

Xavier University- Ateneo de Cagayan is one of the top universities in Mindanao and is located in Cagayan de Oro City. The campus has a cafeteria that offers many food outlets and serves the students and the campus community every day. Almost all people in the campus go to the cafeteria and consume different products contained in plastic materials and one of these plastic materials is HDPE plastic (High Density PolyEthylene). However, the amount of HDPE plastic in Materials Recovery Facility gradually increases, approximately 66% increase from 2014 to 2015.The study aims to recycle the product into a plastic lumbers using solar furnace. The design of the solar furnace is by utilizing parabolic solar reflector with an addition of Fresnel lens. There are two types of Fresnel lens being used, spot lens and linear lens. One of the main goals of this study is to generate a melting temperature using parabolic mirror, parabolic mirror with spot lens, and with linear lens. Once the HDPE plastic is melted using the solar furnace, the molten plastic would be molded into plastic lumbers. Results showed that the highest temperature obtained using parabolic mirror with linear lens and spot lens is 193℃ and 240℃, respectively, which is greater than the required melting temperature of the HDPE plastic of 130℃. Based on the results, the designed XU Solar Furnace has the ability to melt the HDPE plastic materials and recycle it into plastic lumbers.
