The Impacts of Shanghai’s July 2019 Municipal Domestic Waste Management Regulations on Energy Production

Cities all over the world are trying to divert municipal waste away from landfill and fossil fuel-assisted incineration and toward circular economies where waste is converted into new resources. Residential food waste is the most challenging sub-stream, as it is the worst culprit in producing greenhouse gases in landfill and incineration, and it is almost impossible to have residents separate it cleanly at source. Here we investigate the outstanding diversion results of Shanghai Municipality since the introduction of the July 2019 Municipal Regulations, of over 9600 tons per day of clean food waste, still maintained two years later. In particular, we question why they might have increased so sharply after July 2019 and examine historic policies to determine broad policy intentions, their implementations, and officially reported tonnages of different resulting waste streams. It was found that many prior steps included infrastructure building and piloting different behavioral approaches. However, the July 2019 policy brought in legal responsibilities to very clearly defined roles for each stakeholder—including for the residents to sort and for local governances to support them—and this pulled all the operational elements together. The immediate and sustained jumps in clean food waste collection fed biogas production (0.1–1.0 GWh/day) and energy-from-waste (less wet) (5.4–8.6 GWh/day)

Role clarification for local institutions:a missing link in multi-level adaptation planning? Insights from a multiple case study in Botswana

The meaningful engagement of community-based actors in climate change adaptation planning is crucial for effective plans, but achieving it is an ongoing challenge, even with participatory methods. In this paper we explore very different approach, using shared-values crystallization as a pre-process to standard vulnerability risk assessments (VRAs), which recently reported significant impacts on plans produced. We posit this could be due to learning via changed local perceptions of roles, and we use multiple-case study work with five Village Development Committees (VDCs) in North East District, Botswana, and examine VRA outputs, and pre- and post-VRA interview transcripts, for evidence. Findings indicate that VDC members who took part in the shared-values pre-process significantly clarified and prioritized their general roles, and subsequently engaged more deeply in the planning process, taking more responsibility and ownership for the final adaptation plans. They related climate risks to their local lived-realities better, producing quality action plans, funding innovations and mainstreaming of adaptation into wider local plans, alongside an eagerness to present ideas to higher-governance levels. These findings suggest the shared-values pre-process could be immediately valuable for multilevel adaptation planning practices, and that the concept of role clarification deserves more specific consideration in academic studies on participation.</p
