Scientists have recently paid attention to the contamination of soil by MPs as their detrimental impacts on soil systems are largely unknown. MPs are considered to be vectors for other soil contaminants, such as potentially toxic elements (PTEs) and organic contaminants. PTEs are persistent contaminants and are often released into soils in large quantities. MPs adsorb PTEs, mainly via electrostatic attraction and surface complexation, and increase their mobility in soils. These complexes can be easily absorbed by plants; hence, the accumulation of PTEs in plants can be enhanced in both microplastic and PTE contaminated soils. Furthermore, there is a high risk of food chains contamination by PTEs due to crops grown in both microplastic and PTE-contaminated soils. Consequently, countermeasures including policy- and governance-based approaches that target circular economy as well ...

However, Surabaya City failed to maintain this momentum and the positive environmental reputation of the city began to deteriorate. In the mid nineties, Surabaya City faced a tremendous challenge in managing solid waste in an environmentally sustainable manner. In order to help this situation Kitakyushu City, in partnership with a variety of private entities and research institutions including the Japan International Cooperation Agency (JICA) Kyushu International Centre, the Kitakyushu International Techno-Cooperative Association (KITA), the Institute for Global Environmental Strategies (IGES), and the J-Power Group, JPec Co., Ltd., have been working to once a...
