| Research Abstract |
Industrial systems and daily life in Japan are shifting to a recycling-based society to reduce energy and resource consumption. To establish a society based on recycling urban resource recovery centers (mines) are important as places to reduce waste volumes, reusing and recycling valuable materials with application of mineral processing technology. The authors have studied applications of mineral processing in urban mines, and developed new methods and processes as described below.
1)A process for recycling of plastics and metals from scrapped copy machines was developed and the processing pilot plant was constructed using the TACUB jig developed in our laboratory.
2)A metal recovery process from melting plants of incinerated municipal-solid waste was developed using a leaching-sulfudization method.
3)A process recovering electrode materials from waste nickel metal hybrid batteries in a hybrid vehicle was developed using selective crushing at low temperature and 3 stages magnetic separation.
4)A process recovering fine and coarse aggregate and cement hydrate powder from waste concrete was developed using TACUB jig and multi-gravity separator.
5)An advanced process to treat wastewater containing manganese was developed using sulfur reducing bacteria.
6)A microencapsulation method to remediate soils contaminated by heavy metals was developed.
