Millennials' Deals with Plastic: The Effect of Natural Environmental Orientation, Environmental Knowledge, and Environmental Concern on Willingness to Reduce Plastic Waste

Abstract

To maintain environmental sustainability can be managed and resolved by changing human behavior, especially by reducing plastic waste. This study investigated whether natural environmental orientation, environmental knowledge, environmental concern, and environmental attitude affect the extent to which millennials avoid or reduce the purchase of single-use plastic tableware, food with plastic packaging, and plastic water bottles called Willingness to Reduce Plastic Waste (WRPW). This study used quantitative using the purposive sampling method. Data collection techniques using online questionnaires were sent to respondents with criteria for educated millennial Muslims at Islamic universities in East Java, Central Java, and West Java. The survey was conducted for three months and obtained 369 respondents. The questionnaire is processed by using SEM analysis with Smart PLS. The results show that environmental knowledge provides a direct and an indirect effect on willingness to reduce plastic waste through environmental attitude. Meanwhile, environmental concern has no direct effect on willingness to reduce plastic waste, yet it has an indirect effect through environmental attitude. This research implies that concern for the environment is not necessarily accompanied by the willingness to reduce the use of plastic. However, adequate knowledge about the environment can increase the willingness to reduce the use of plastic among millennial generations who prioritize logical thinking and adapt to their knowledge.

Processing Banana Peel Organic Waste in Tourism Areas as an Effort to Control Aquatic Environmental Pollution

“…Pada dasarnya, masyarakat mengerti akan dampak negatif yang ditimbulkan oleh sampah, namun perilaku acuh menyebabkan kurangnya kesadaran menjaga lingkungan sekitar (Puteri & Yuristin, 2020) berserakan di jalan, selokan, pesisir pantai, perairan laut dan lainnya menjadi pemandangan sehari-hari yang dapat dilihat. Sampah anorganik berupa botol, gelas dan kantong plastik mendominasi sampah yang terlihat sehari-hari karena konsumsi sampah tersebut cukup tinggi (Solekah et al, 2022). Dampak sampah anorganik plastik sudah diketahui berbahaya bagi lingkungan khususnya manusia.…”

“…Environmental concern refers to the awareness and consideration of environmental issues, which can positively influence individual behavior (Adnan et al, 2018).

Environmental concern is an individual's supportive attitude toward solving environmental problems (Chaudhary, 2018).…”

Understanding the interplay of environmental orientation, climate change beliefs, innovativeness, and attitudes in agricultural production

“…Understanding farmers' approaches to sustainable agriculture and climate change adaptation techniques is based on this attitude. Farmers have different farming preferences and lack a common sense of self (Solekah, Handriana, & Usman, 2022). According to Gull, Saeed, Suleman, and Mushtaq (2022), a farmer is often seen favorably if he employs sophisticated equipment and inorganic fertilizers and is concerned about the environment.…”

“…A farmer's decision-making process in agriculture en-ables the assessment and formation of positive or negative beliefs about agricultural production. Foundational theories on attitudes suggest that people's decisions can reveal their attitudes, even when measuring the process of belief development may not always be feasible (Howe et al, 2019;Solekah et al, 2022). Depending on their demands for output or the circumstances of their home, individual smallscale farmers have been seen to behave differently in practices (Fairbrother et al, 2019;Gull et al, 2022).…”
