Determination of the knowledge of e-waste disposal impacts on the environment among different gender and age groups in China,Laos,and Thailand

Abstract

E-waste is the fastest growing waste in the solid waste stream in the urban environment. It has become a widely recognised social and environmental problem; therefore, proper management is vital to protecting the fragile environment from its improper disposal. Questionnaire surveys were conducted to determine the knowledge of environmental impacts of e-waste disposal as it relates to mobile phones among different gender and age groups in China, Laos, and Thailand. The results revealed that gender was positively correlated with their knowledge of the status of environmental conditions (P₁₀₄) (r = 0.077, n = 1994, p < 0.01) and negatively correlated with their knowledge of how to improve environmental conditions (P₁₀₅) (r = –0.067, n = 2037, p < 0.01). In addition, an increase in age was positively correlated with respondents’ concern over the environmental conditions (P₁₀₃) (r = 0.052, n = 2077, p < 0.05) and P₁₀₅ (r = 0.061, n = 2061, p < 0.01) mentioned above. The results indicated that female respondents were less knowledgeable about how to improve environmental conditions than male respondents in the three countries. Knowledge gaps were detected in the respondents, at age ⩽17, in the three countries, and from age 18–22 to 36–45 or older from Thailand and China, on their knowledge of the existing e-waste-related laws. Thus, an effort to bridge the gaps through initiating proper educational programmes in these two countries is necessary.
