Researchers and donors consider informal recyclers as an important part of improving waste management in developing countries. This study investigates data relating to the recycling rate of waste pickers in Bantar Gebang, Republic of Indonesia. The study estimates the net weight of soft plastic and hard plastic recycling achieved by these waste pickers. Data were obtained from qualitative and quantitative field surveys conducted over a total of 808 days, from February 2010 to January 2018. Based on 78 households with a total of 156 individuals, the average monthly weight of collected recyclables was 126.7 kg per household. The average monthly weight of collected recyclables on an individual basis varied between 81.0 and 63.3 kg, depending on the number of informal recyclers in the household. The estimated total weight of collected recyclables was 3617.6 tons per month. Bosses sold these collected recyclables to different recycling factories depending on the expected profit. It was estimated that the activities of the waste pickers produced at least 725.4 tons of recycled pellets of soft plastic and 280.8 tons of recycled pellets and flakes of hard plastic. The informal recycling rate for all waste and non-organic waste on the site was 1.6% and 9.3%, respectively.

Nine years have passed since the accident at the Fukushima Daiichi Nuclear Power Plant, but it is still difficult for residents to return to their homes in some municipalities. In addition, it takes 30 to 40 years to deal with the accident, which requires long-term efforts and decision-making across generations. In order to construct such a project for the reconstruction of Fukushima, co-creation project management by multigenerational and diverse actors is necessary. In this research, we analyze project continuity from the viewpoint of P2M, with the aim of realizing social innovation, which is a long-term strategy, through initiatives such as Future Sessions at the Fukushima Study Group.

The hard infrastructure developments are the central issue in Fukushima reconstruction in spite of over eight years that have passed since the Fukushima nuclear accident. Therefore the development of the software program which identifies and resolves problems from the view of local communities and residents for Fukushima reconstruction is still lacking. The scope of research of the Fukushima Hirono Research Center for Sustainable Region (FHRC) embraces whole communities and the organizations in the affected areas in Fukushima. Mainly, it functions as an academic research base on the creation of social innovation for Fukushima reconstruction. The FHRC is creating a project to solve the problem by clarifying Fukushima recovery issues by creating a place that dialogue-based with various actors across fields and multi-generation. This research analyzes the process of creating a place for social innovation and fostering social acceptance in Fukushima.

Regarding the geological disposal of high-level radioactive waste (HLW) in Japan, there has been no widespread public debate. As no candidate site selection has progressed and it is long way to proceed the HLW disposal project. In order to overcome this situation, currently, technical one-way communication by experts is conducted under assumption of citizen’s lack of technical safety. The approach has been criticized as a ”Deficit model”, but because of its ambiguity, it is still discussed today. This paper applies the method of P2M theory to aim the public debate of the HLW disposal by analyzing the citizen’s policy preference change with 4 social acceptance factors (technical, institutional, economic and regional factors). The “Deficit model” communication case is tested and shows the limit of the current dialogue project of the HLW geological disposal which is placing too much on the technical safety.
