A systematic and critical review of waste management in micro, small and medium-sized enterprises: future directions...

Waste management (WM) has received increasing attention in recent years in micro, small, and medium-sized enterprises (MSMEs). However, a comprehensive understanding of the WM research in MSMEs from different economic sectors is somehow absent in spite of its proliferation. The current review was conducted to indicate types of waste, hazards associated with waste, as well as strategies, antecedents (facilitators and barriers), and outcomes of WM in MSMEs from diverse economic sectors. The search was performed by using the Web of Science (WoS) database, which retrieves 420 articles. After excluding the papers that were not closely related to the topic, 84 articles were retained for an in-depth analysis, spanning a period of five years (from 2018 to June 2022). This review demonstrates that the types of waste generated from MSMEs include metals, plastics, chemicals, papers, wood, fabrics, stones, food, ceramics, glass, candles, and cooking oil, among others. It is also resulted that the hazards associated with waste include environmental pollution, CO₂ emissions, human diseases, health disasters, and marine life destruction. Examples of the WM strategies in MSMEs research are recycling, separating, sorting, reusing, and composting waste. The findings revealed that a lack of financial resources, knowledge, experience, education, and training are some barriers encountered by MSMEs in WM. Enhancing financial performance, economic growth, competitive advantage, and sustainable development are important outcomes of WM in MSMEs. There has been a paucity of research on MSMEs WM, necessitating a thorough investigation of several issues. This research discusses implications and recommendations and presents avenues for future research. The current paper is one of the first studies to conduct a systematic review of WM in MSMEs from different economic sectors.
