A pathway-resolved national model for quantifying environmental loads from pet-dog waste: A case study of South Korea
Summary
Researchers built a national pathway-resolved mass-balance model for South Korea to quantify how pet-dog waste is disposed of across landfill, sewer, and open-environment routes, identifying it as an underappreciated but quantifiable source of microplastics and nutrients entering urban water systems.
Pet-dog waste (PDW) represents an emerging waste stream linking municipal solid waste and urban water systems, yet its pathway-specific environmental loads remain unquantified at national scale. We develop a pathway-resolved mass-balance model for South Korea that allocates PDW into three disp...
