Emission reduction benefits and efficiency of e-waste recycling in China

摘要

Recycling of e-waste is an effective means for e-waste management. It has made great contribution to improving environmental benefits. This paper evaluates the emission reduction benefits and efficiency of e-waste recycling in China, using the direction distance function of DEA. Calculations show that from 2013 to 2017, the total emission reduction benefits of 29 provinces in China e-waste was 6.34 billion yuan, with an average emission reduction efficiency of 0.88. The emission reduction benefits of CO_2 was 390 million tons, and the average emission reduction efficiency was only 0.82. The wastewater emission reduction benefits was 570 million yuan, with an average efficiency of 0.9. The emission reduction benefits of solid waste and SO_2 are 5.37 billion yuan and 400 million yuan respectively, with the same emission reduction efficiency of 0.89. E-waste recycling in China still has huge potential for emission reduction.
