Energy, environmental and economic assessment of a manufacturing plant with practical solutions

Abstract:

Considering the role that China has in the industry which triggers challenges in the environmental, economic and energetic sector. This study aimed to evaluate the energy consumption key points for a manufacturing factory located in Shanghai and propose practical projects to improve its performance. The methodology followed an inventory analysis and theoretical calculation in the three sectors mentioned, being the most representative the emissions of carbon dioxide, payback period and the standardization of the energy units. Among the results, the most energy-consuming areas and equipment were found; then, three projects were suggested to implement: The installation of a heat recovery system for the air compressor system, an insulation layer for the injection machine and installing a new air compressor, plus several common suggestions for manufacturing plants. Most of the projects presented a payback period lower than two years and relatively fast implementation for manufacturing plants.
