A multi-stage sampling approach guided the selection of participants for the study. A structured questionnaire and interview guide were the instruments for data collection. Data analysis involved descriptive statistics and thematic analysis. Finding revealed that majority (51%) of the respondents use facebook and TikTok several times everyday. Moderate level of exposure to CE principles was observed. Majority (55%) of the respondents understand that circular economy model promotes waste reduction and effective materials management. 51% and 50% rejected that their awareness and engagement in CE are linked to Facebook and TikTok messages.
