“…Previous studies on MHW separation mainly focused on the principal factors affecting MHW separation and participation behavior, which provided support for decision makers/stakeholders to choose the best scheme. The key factors affecting the behavior of MHW separation and participation include internal factors such as attitude and knowledge (i.e., behavior attitude, environmental awareness, recycling and separation knowledge) [15][16][17][18][19][20][21], external factors such as social ties (i.e., families, friends, and neighborhoods) [5,[22][23][24][25][26], facility convenience (i.e., separation facilities, distance to recycling, time costs, facilities) [2,27], economic and policy incentives (i.e., regulations, laws, economic profits, government subsidies) [2,[28][29][30][31], technology (i.e., digital technology, bio-energy technology) [32,33], publicity and education [34], and individual social digital factors (i.e., gender, age, income, educational level, etc.) [35,36].…”
