Rapid urbanisation, population growth, and rising consumerism have made plastic trash management in emerging countries a major environmental issue. This chapter covers plastic waste management in developing countries, outlines their main issues, and suggests ways to handle this rising issue. Developing waste management infrastructure in developing countries needs to catch up to the exponential rise. Plastic garbage often ends up in open dumpsites, rivers, and oceans, endangering ecosystems, human health, and socioeconomic development. Due to resource shortages, awareness gaps, and government capacity constraints, innovative and sustainable solutions are needed. Lack of recycling facilities, low garbage collection rates, insufficient waste segregation, and non-biodegradable polymers in common products complicate plastic waste management in developing countries. Insufficient financing, regulation enforcement, and a lack of cutting-edge technologies significantly restrict plastic garbage management. This chapter suggests that developing countries can combat their plastic pollution crisis by integrating informal recycling into formal waste management systems, public awareness campaigns and educational programmes, innovative technologies like waste-to-energy conversion and chemical recycling, and international knowledge exchange and technology partnerships. Proper plastic waste management in developing countries can protect natural habitats, biodiversity, and climate change, create jobs, boost local economies, and promote sustainable development. These countries may contribute to global plastic pollution reduction by overcoming obstacles, using new techniques, and grabbing opportunities.
