Final answer:
China is the developing country with the highest rate of municipal solid waste generation, facing growing waste management challenges.
Step-by-step explanation:
According to the article 'Sustainable recycling of municipal solid waste in developing countries', the developing country with the highest municipal solid waste generation rate is China. Developing countries are seeing a rapid increase in waste generation; while high-income countries such as the United States have high environmental standards, middle- and lower-income countries like China are still developing their infrastructure and standards, which contributes to higher waste generation rates.
China's MSW composition reflects its waste challenges, with a significant proportion consisting of food residue, demonstrating the magnitude of organic waste in the country. Recognizing the importance of environmental protection standards, China and other developing countries are likely to increase their environmental protection efforts as their economies grow and standards of living improve.
