Upcycling and Transforming Poly-Ethylene Terephthalate (PET) Bottles into Value Added Products for Household and Interior Decoration

This study investigated the upcycling and transformation of polyethylene terephthalate (PET) bottles into value-added products for household and interior decoration. Conducted at FUNAAB International School (FUNIS) and Muslim High School in Isolu community- Abeokuta, Ogun State, Nigeria. The research adopted a mixed research design which involved a practical (experimental) and theoretical aspects (quantitative). A mixed sampling technique (purposive, stratified, and simple random/convenience sampling) was employed to select 150 student respondents. With upcycled PET products household and interior decoration displayed, data were collected using a structured questionnaire and analyzed using descriptive statistics (frequencies, percentages, and mean scores) and an independent t-test for hypothesis testing. The findings revealed high levels of preference and acceptance for upcycled PET bottle products. Specifically, 78.7% of respondents agreed that upcycled baskets are affordable (M = 1.79, SD = 0.41), while 80.0% affirmed that lamps would be appreciated by environmentally conscious consumers (M = 1.80, SD = 0.40). Durability perceptions varied: 72.0% rated baskets as wear-resistant (M = 1.72, SD = 0.45), whereas only 59.3% agreed for lanterns (M = 1.59, SD = 0.49). The independent t-test revealed no statistically significant difference in perception between FUNIS (M = 3.22, SD = 0.69) and MHSI students (M = 3.06, SD = 0.58), with p = 0.144 (
