1 Background and question
Background and question Facts of informal collection 1. Informal collection cause problems. 2. Integration of informal collection in in need. 3. 20 cases of informal sector integration showed the policy/legal and institutional barriers Facts of intelligent collection 1. 87 cases of ICTs application in waste management 2. 5 cases of intelligent collection in EU and more in China 3. Experience in EU proved to enhance collection efficiency by technology application 1. What are the intelligent collection in China? 2. What are their potential to integrate informal collection?
2 Methods
Methods u. Interviewed 15 intelligent collection cases with open questionnaire and filed survey. u. Interview content focused on: • Investment • Operation location • ICTs & Io. Ts tools application • Flow chart of material, cash, information. • Achievements • Challenges • Policy advice
3 Result 1: Two models of inte collection
Result 1. Two models of intelligent collection HM Interaction model HH Interaction model
1. Two models of intelligent collection HM Interaction machine HM Interaction scene
1. Two models of intelligent collection HM collection HH collection Informal collection ICTs tools adopted Barcode, GSM/GPRS, Sensors, Smartphone APP、Web, GSM/GPRS, GIS, Smartphone N/A Applicability PET bottles, Collect by machine, Textiles, Kitchen trade in electronic waste currency All recyclables Forms Collect by collector at door via appointment, trade in electronic currency Collect by collector at door randomly, trade in cash.
4 Result 2: Four comparative advantages of intelligent collection
Result 2. comparative advantage of inte collection 1): Organised intelligent collection
Result 2. comparative advantage of inte collection 2): Efficient material and cash flow of intelligent collection
Result 2. comparative advantage of inte collection 3): Big data of intelligent collection Intelligent collection system monitors 5, 000 PET bottle collection machines in Beijing
Result 2. comparative advantage of inte collection 4): Multi profit-making of intelligent collection u Recyclables trade u Other service at collection u Big data mining u Policy benefits
5 Conclusion
Conclusion What u Comparative advantages of intelligent collection How u. Hiring informal collectors. u. Providing waste source separation u. EPR for some high value recyclable resources. TBC ? show that it has the potential to integrate the informal collection.
