The sustainable development principle states, “meeting the needs of the existing without compromising the needs of succeeding generations.” Increasing population is directly proportional to the heightened resource consumption, thus leading to significant waste generation. Waste generation is not the problem, but rather nonstrategic disposal and management of waste are the problems. Modern problems demand modern solutions. This chapter “Innovative Strategies for Sustainable Waste Disposal” enfolds the innovative strategies and approaches for waste disposal, projecting toward environmental sustainability. The “3R initiatives” that is reduce, reuse, and recycle, launched in Japan in 2005 and later implemented worldwide, was one such approach. However, over the period, more approaches come to light such as composting, anaerobic digestion of waste, and incineration. With the advent of artificial intelligence, waste disposal and management have taken a new path. The introduction of smart bins and raising awareness among people about segregating different types of waste from the home and their packaging in color-coded garbage bags have been decisive. In this chapter, the concerns for irresponsible waste disposal and how badly this act harms the environment in long term are addressed. To protect the environment from the fatalistic effects of the inappropriately and nonstrategically disposed waste, innovative approaches are to be adopted and implemented more openly and new innovative strategies must be designed. This chapter focuses on the need of developing innovative approaches combining with new technologies. It highlights the limitations possess by traditional methods and create space for improvement in them. With this chapter, authors aim to raise awareness on the root causes of waste generation and reflect the idea of innovative waste disposal strategies.
