Eco-design is an advanced design approach which plays an important part in the
national innovation project and serves as a key point for the successful transformation of the
supply structure. However, the practical implementation of the pro-environmental designs and
technologies always faces a dilemma situation, where some processes can effectively control
their emissions to protect the environment at relatively high costs, while others pursue the
individual interest in making profit by ignoring the possible adverse environmental impacts.
Thus, the assessment on the eco-design process must be carried out based on the
comprehensive consideration of the economic and environmental aspects. Presently, the
assessment systems in China are unable to fully reflect the new environmental technologies
regarding their innovative features or performance. Most of the assessment systems adopt
scoring method based on the judgments of the experts, which are easy to use but somewhat
subjective. The assessment method presented in this paper includes the environmental impact
(EI) assessment based on LCA principal and willingness-to-pay theory, and economic profit
(EP) assessment mainly based on market price. The results from the assessment are in the form
of EI/EP, which evaluate the targeted process from a combined perspective of environmental
and economic performance. A case study was carried out upon the utilization process of coal
fly ash, which indicates the proposed method can compare different technical processes in an
effective and objective manner, and provide explicit and insightful suggestions for decision
making. |
