The world’s trash problem is a long-term issue and is not expected to solve away in the near future. The traditional garbage management systems like incineration, landfill, composting, recycling, waste compaction, underground disposal have its own drawback and are not equipped to manage with the hues waste generated by the current day industrialization and population growth. The environment and human health can be harmed by improper waste collection, treatment, and also disposal. The types of wastes that are generated such as agricultural waste, municipal solid wastes, hazardous waste, biomedical waste, industrial waste, and chemical waste need to be disposed in a non-detrimental way. Waste containing hazardous substances can endanger human health and harm natural ecosystem. To solve this problem, efficient and sustainable waste management is becoming more and more crucial. Hence, to overcome the issue, it is required to adopt smart waste management technologies that can increase the management efficiency, minimum collection cost, and can divert more and more waste away from the sanitary landfills. The smart innovative technologies for management of wastes are like ‘smart waste bins, waste level sensors, e-waste kiosks, pneumatic waste pipes, artificial intelligence (AI) recycling robots, garbage truck weighing mechanisms, solar-powered trash compactors, recycling apps’, etc. It has been studied that start-ups have received grants of multimillion dollars during the year 2021 in order to develop smart environmentally friendly technologies. It is expected that the smart waste collection market to reach revenue of about $4.5 billion in the year 2027. Further, the state governments are looking to adopt stringent waste recycling regulations. The present study aims to discuss the various smart and innovative waste management techniques for a sustainable and greener environment.
