Keywords in NIES

  • "Municipal solid waste (MSW)" primarily consists of waste from our daily lives. In Japan, nearly 80% (by weight) of MSW is incinerated. Through the incineration process, organic matters in MSW become gases such as water vapor and carbon dioxide and are released from smokestacks. The remaining incineration ashes consist of stone-, ceramic- or glass-like materials and their finely crushed particles, including various metal fragments. Incineration ashes thus have high concentrations of precious metals (e.g., gold and silver) and hazardous metals (e.g., lead and cadmium) that were inconspicuous in MSW before incineration.
  • Johkasou: on-site domestic wastewater treatment system Johkasou, like sewerage, is a system for domestic wastewater treatment. While sewerage is a centralized system that collects wastewater from tens of thousands of households and treat it at a plant, Johkasou is a decentralized system.

Discovering the Social Mechanisms of Waste Management

“Let me explain the rules for trash here in Japan. On average, 10 to 20 households set up a collection point. Residents walk or drive with their trash to the collection point. Trash is separated by each household, and separation rules are different in each municipality. In this situation, an increasing number of elderly people are finding it very difficult to take out the trash on a routine basis.

Keywords: Local community, Neighborhood association, Super-aged society, Taking-Out-the-Trash, Waste collection point
