The Impact

The output of municipal solid waste is growing rapidly, which has brought tremendous pressure to urban development. The supply chain of municipal solid waste (MSW) in China mainly contains three processes: collection, transportation, and disposal. The waste is sorted at the collection and disposed of according to the classification. However, it is mixed at the transportation stage. Mixed transportation remixes the separately collected waste, which seriously affects the disposal effect. The supply chain of MSW urgently needs to be redesigned to improve the MSW disposal effect. First of all, on the ground of the waste treatment situation, we redesigned the supply chain of MSW in China. Secondly, combined with the redesign of the MSW supply chain, this paper established the function allocation model for collection stations, making a collection station only gather one type of waste, and built the transportation path planning model for vehicles, reducing the impact of waste storage on residents. Finally, based on the data of Xuanwu District in Beijing, the supply chain redesigning practical example of incinerable waste was given. The supply chain redesigning model in this paper not only makes full use of the existing infrastructure but also improves the disposal effect of waste. The supply chain redesigning model has practical application value.

The Impact

This case study is monitoring the impact of pH, nitrate, nitrogen in groundwater around Vidra landfill located in Ilfov; we used two monitoring wells, F19, and F10. For the obtained values, the following conclusions emerged: water from monitoring well F10 showed much higher loads compared to water from the monitoring well F19 on organic loading indicators (CCO-Cr, BOD5); although other values and indicators were higher in the monitoring well F10 to those obtained for the  monitoring well F19.

The Impact

Incineration is the main way to dispose the municipal solid waste (MSW) in Taiwan. The amount of MSW is rapidly decreased during recent 10 years due to the policies implementation of waste reduction and resource recycle since 2003. Assessment of incinerator operation stop and transformation therefore becomes an essential issue. An evaluation framework was constructed and put into practice in this research. With the considerations of service status, operation performance, MSW treatment status and the impact level of stopping operation was integrated and assessed in the first stage. An optimal model was built for re-programming the MSW clean strategies of original service areas by taking account of MSW collection distance, design capacity of incinerators and the heating value of solid waste in the second stage. A case study was implemented for four incinerators in Kaohsiung City of southern Taiwan to demonstrate the feasibility of proposed assessment framework.

Set Up

India generates 0.15 million metric tons (MT) of solid waste per day out of which more than 80% is organic fraction. Apart from this, 38% of the households use septic tanks where proper disposal of faecal sludge is also need of the hour. Anaerobic co-digestion (ACD) of two different substrates has positive potential towards solving this problem. In the present study, ACD of organic fraction of municipal solid waste (OFMSW) and septage solids (SS) was studied at three different levels, i.e., lab-scale, pilot-scale (1 m3), and full scale- capacity (325 m3). A loading rate of 1.5 kg VS/m3 was selected. The bio-methanation potential (BMP) assay showed a maximum biogas generation, i.e., 120±20.6 mL/gmVS with 68% maximum methane concentration at a 5:1 OFMSW and SS ratio. Cumulative biogas production after 30 days was 1.6 L/gmVS. The ultimate biogas production in the pilot-scale plant was 1000±100.5 L/day with 71% methane. The plant was also efficient in removing 87% of COD and 61% of VS. The full-scale anaerobic digester was set up at Mormugao Municpal Council, Goa India wherein the objective was to co-digest OFMSW and SS. This digester showed a similar removal pattern like earlier studies i.e., 94% and 45% COD and VS removal, respectively. The average methane content of the biogas was 68%. Full-scale operation of the anaerobic digester did not show any operational problems at the chosen co-digestion conditions.
