Experiments on a blockchain-based waste classification management platform and evaluation of entropy-cloud model
Based on the four characteristics of blockchain technology(BT),namely decentralization,traceability,tamper-proofness and incentive mechanisms,this paper constructed a blockchain-based waste classification management platform with the functions of points incentive,publicity and educa-tion,online transaction and data traceability and selected a pilot district in Hefei City to test the effec-tiveness of the platform through questionnaire survey,field sampling and physical component analysis from January to September 2022.The results show that the recycling potential of recyclable waste in-creases by 20.4％compared to pre-test,and the food waste mixing rate decreases by 23.5％;the pub-lic support and participation rate exceeds 95％as of September 2022,and the successful traceability rate of violations reaches 83.2％.Meanwhile,the paper introduced the entropy-cloud model for the first time to evaluate the blockchain platform.The results show that the comprehensive determina-tions of waste classification management in the S1(January-March),S2(April-June)and S3(July-Sep-tember)trial phases are 2.53,2.66 and 2.82,and the comprehensive evaluation grades are Ⅳ(poor),Ⅲ(fair)and Ⅱ(good),respectively.The platform can solve the universal problems of poor classifica-tion quality and low public participation,and meet the requirements of the era of mandatory waste classification in China.The entropv-cloud model can consider the randomness of questionnaire and sampling results,and realize the transformation from qualitative concept to quantitative data,which is innovative and feasible in the field of waste classification management.
