Factors Influencing Knowledge on Single-Use Plastics and Their Management Among Traders in Selected Markets in Accra

Abstract

Plastic pollution, encompassing single-use plastics (SUPs), poses a persistent global threat across societies. This research examines the factors that affect traders' knowledge about SUPs and their management in specific markets in Accra, Ghana. A cross-sectional study design was utilized, gathering data from 415 traders in three selected markets in Greater Accra through a semi-structured questionnaire. Descriptive and inferential statistical analyses, including independent samples t-tests, one-way ANOVAs, and chi-square tests, were conducted. The results indicate that traders have a strong knowledge of the public health (mean score = 5.56/6, 92.7% achievement rate) and environmental consequences (mean score = 5.79/7, 82.8% achievement rate) of SUPs, achieving average rates of 92.7% and 82.8%, respectively. Their comprehension of the economic effects was somewhat lower, with a 74.2% achievement rate. Higher education, especially tertiary degrees, strongly predicts greater knowledge, particularly in public health (F(4, 410) = 17.858, p < 0.001), environmental (F(4, 410) = 32.876, p < 0.001), and economic knowledge (F(4, 410) = 36.046, p < 0.001). A significant portion of traders (67.2%) favoured a ban on SUPs, with significant associations with higher environmental (χ²(1) = 33.59, p < 0.001) and economic knowledge (χ²(1) = 60.58, p < 0.001). Traders proposed various sustainable alternatives, such as stainless steel, bamboo, and bio-based plastics. Traders in Accra know the harms of SUPs but need more economic insight. Many support a ban and sustainable alternatives, showing potential for policy change. To reduce plastic use, we need education, financial incentives, stronger regulation, and collaboration to create a green environment.
