Waste management and plastic waste recycling in Japan, China, Singapore and South Korea - What trends can be observed under different regulations

Abstract

Plastic pollution of oceans and seas is increasing every year and coastal countries need to pay particular attention to this problem. Four Asian countries - Japan, China, Singapore, South Korea - were analysed in terms of the amount of waste and plastic waste generated and their recycling rates. For each country, available data were collected and converted into a common unit of measurement - metric tonnes per 1,000 people. The countries' performance to date was analysed and used as a basis for projections for 2030. Based on the trends so far, Japan has seen an 11% reduction in plastics waste and a 6% reduction in waste over the period, while China has seen a 27% increase in waste and an 8% reduction in plastic waste. In South Korea, plastic waste increased by 49% and waste by 21%. In Singapore, waste decreased by 13% and plastic waste increased by 15%. On current trends, none of the countries are projected to reach their 2030 targets. However, by complying with current and newly introduced regulations, they have a chance to move closer to their targets.
