  1. BH60A1101 Environmental Technology Project Work: Sustainable Innovation CourseSolid waste treatment and management on water-based of Mekong delta area of Vietnamese region

  2. Content: 1> Background of project Climate change effects – The flooding risk Mekong delta case – DongThap province, Vietnam Current situations and toward to sustainability development 2> Project development Solid waste treatment and management options – The core technology or processes v.s sustainability and local Supply chain – logistic, markets Economical feasibility (subsidies, employment, saving) Auxiliary processes/technologies (IT, tools, education) Networks (Government, NGO) Scaling up the project 3> Limitation of project

  3. Background of project Footer

  4. Background of project The Nobel Prize-winning 2007 Intergovernmental Panel on Climate Change (IPCC) Report identifies Southeast Asia as among the most vulnerable regions on Earth. This is due in part to the geography of Vietnam as a low-lying coastal nation, the absolute number of people living in vulnerable, low elevation coastal zones (LECZ), defined as the contiguous area along the coast that is less than 10 m above sea level

  5. Background of project Vietnamese researchers predict that a sea-level rise of 100 cm would cause a predicted land loss of 40.000 km or 21.1 % of the Mekong River Delta’s land mass. This level of loss would expose and/or displace 17.1 million people, which is 23.1% of the population. For instance: Dongthap province - A province in Vietnam is a region located in the end of Mekong river. This province has about 1.67 million population in the area 3283 km2, population density 507 people per km2.

  6. Background of project Energy Fresh water Waste Transportation Economy Electricity in 2011 around 1,240 GWh and more than 99% families get electricity connection, electric price is 33-65 cents per MWh Fresh water is for 85% families in 2010, the price is around 10-20 cents per m3 Solid waste is 3.7 million ton per year, from domestic waste around 2.3 million ton per year including manure, percentage of organic waste is around 59% and recycle waste is only 13%, the treatment cost for each family is about 50 cents per month.

  7. Background of project Raining season: from May to November Drying season: from Dec to Apr 39000m3/sec in raining season. In the flood case, the water level can reach 4 meters above sea level Advantage: recharge ground water, making soil more fertile and provide nutrients, ect. Disadvantage: physical damages, water supplies, diseases, transport, economic, ect. Footer

  8. Background of project Sustainability development suggestion: • Energy: hydropower based, biogas • Water: raining storage, disinfection • Agriculture – Food: new technology • Health: improve sanitation system • Education: SD awareness, flooding risk management • Transport: boats, bridges, flood surviving kits, swimming training • Information: new development • Economy: fishing, new development • Architecture: new structures • Waste – The scope of project! The solid waste management problems to this province are lack of facilities to collection system, old and ineffective landfill plants, difficulties in the wet season whenever flood occurs

  9. Project development From Ark’s Project ‘One’ of Linda Beamish – Eco-Ark Design Consultant with solutions for an organic & ethical farm in a high risk flood zone. Footer

  10. Project development Smart Waste Snorkeler (SWS) System was proposed for underwater waste management after the grand flood in 2031 Footer

  11. Project development Floating Architectural Structures Ideas Footer

  12. Project development Landfill technology basis and toward to the floating or water –based treatment to organic waste Footer

  13. Project development Consider modified container structure Utilize barge structures Waste storage and closed treatment

  14. Project development Project achievement: improve awareness of population to segregate solid waste by put different kind of containers for organic waste, recycle waste and hazardous waste. Consider using the recycled material bags made from coconut cover or grass, leaves. • Proposal solid waste treatment on water –based: • Should have a floating supporting structure and enough strong in flood case • Leakage prevention systems • Closed system and can fermentation organic waste to produce biogas for energy usage • Easy to put waste inside and automatic closed Fixed volume

  15. Project development • Supply chain: • Suppliers: containers, barges, waste bags, transportation, supporting structures • Customers: residential area for around 20” volume of solid waste • Saving current solid waste treatment costs • Investment cost for one unit: • Barge cost: >30,00EUR (200ton) • Container cost: 1500EUR • Other cost • Employment: • Create new production – waste bags from biodegradable materials at local • Employees for operating and collecting of this system

  16. Project development • Education: solid waste segregation to each family, sustainability development, health effects from untreated solid waste in the flood case, living with the flood training • Networks: budget investment to purchase and install the system, subsidies to bags production, fines to families not collection and separate waste, sell biogas for users • Scaling of projects: can apply for Mekong Delta regions • Technology development: Government or NGOs support the budget on technology development of solid waste treatment methodologies on water-based.

  17. Limitation of project • Time limitation and resources to design or study new technology for waste treatment • Geography limitation and experiments or data collection • Not consider recycle waste or hazardous waste • Not calculate exact the number of population, just assume Mekong delta region, and solid waste volume or timing of treatment • Not define exact place to place the project in the residential area • Need more studies how to link to sustainability development like creating biogas for energy at least during the flood season or fertilizers for agriculture from the project • Not discuss to industrial waste

  18. Conclusion • Raise the new technology of solid waste treatment based on the flood case to open the problem of technology solutions in case it can not be applied landfill or incineration Footer
