“THE-BEST-OF-2-WORLDS PHILOSOPHY: DEVELOPING LOCAL DISMANTLING AND GLOBAL INFRASTRUCTURE NETWORK FOR SUSTAINABLE E-WASTE TREATMENT IN EMERGING ECONOMIES”

Shweta Basu, 13105396

BEST-OF-2-WORLDS PHILOSOPHY Provides a network and pragmatic

solution for e-waste treatment in emerging economies.

It seeks the technical and logistic integration of ‘best’ pre-processing in developing countries to manually dismantle e-waste and ‘best’ end-processing to treat hazardous and complex fractions in international state-of-art end-processing facilities.

STAGES OF E-WASTE TREATMENT CHAIN Stage 0 (Collection) Stage 1 (Toxic Removal) Stage 2 (Pre-processing) Stage 3 (End-processing)

DIVERSITY OF E-WASTE TREATMENT CHAIN: CASE STUDY OF GOLD RECOVERY FROM COMPUTER

COMPARATIVE SCENARIOS AND EVALUATION METHODS

RESULTS:

ECONOMIC DISTRIBUTION ALONG TREATMENT CHAIN:

•Pre processing profit= revenues from selling the liberated scrap – fixed and operational cost•End processing profit= revenues from the recycled materials – purchase cost of secondary scrap, fixed and operational.

ECO-EFFICIENCY SCORES UNDER TH BO@W RECYCLING APPROACH:

The material composition of products has direct influence on its profitability and environmental impact occurred during the same treatment processes. Products containing substantial amounts of metals have higher eco-efficiency scores than products dominant in plastics or other low value materials.

MARKET PRICES OF RESOURCES AND LABOUR COSTS:

CONCLUSIONBo2W philosophy is novel to provide an

alternative of conventional approaches adopted in e-waste management. It is more pragmatic and economic compared to the construction of a comprehensive recycling chain with all necessary pre-processing and en-processing facilities available locally.
