Toward the establishment of a resource recycling society, there is a growing need in the waste treatment sector for separately collecting, to the extent possible, biomass such as kitchen waste (food waste) and paper from waste and recycling it. However, it is not easy to separately collect biomass from waste containing plastics, metals, etc., and it has become a challenge in the promotion of recycling. Mitsubishi Heavy Industries, Ltd. (MHI) Group is advancing the development of technologies for facilitating the separate collection of biomass resources from waste that had to be incinerated due to the difficulty in separate collection and converting them into recyclable materials. The overview and features of this system are introduced in this report.
