The
cogeneration category is found to have the low cost effectiveness due to its high investment required.
The abatement costs of the energy conservation measures was calculated to assess the economic
feasibility. Almost all measures were economically feasible, except for some measures under the energy
efficiency category. To encourage non-cost-effective measures, carbon credits should be promoted to
cover the implementation cost of the measure. The results in this research will be useful for industrial
sector, petrochemical companies, and other interested parties for transformation towards industrial
sustainability.
