| Abstract | In today's economic scenario, taking into account environmental concerns, more and more
sugar factories are now .considering energy and environmental issues. The overall objective
of this study was to improve the performance of cane-sugar industry through Cleaner
Production measures. The study was conducted in two cane-sugar factories, Factory A and
B, in India, which is the world's second largest sugar cane producer. It was undertaken to
analyze the energy and environmental performance of the sugar mills, suggest suitable
Cleaner Production options for implementation and to provide assistance to the facto1ies'
management in following up the pe1formance efficiently.
The Cleaner Production approach adopted combines various issues: energy demand and
supply, pollution, natural resources, financial and monitoring-reporting. Three major
phases were considered: (1) making a Cleaner Production audit in both factories, (2)
suggesting and discussing Cleaner Production options for implementation in Factory A and
(3) improving monitoring and reporting in Factory B. Analytical tools employed include
energy and mass balance, cost-benefit ratio, financial cash flow and energy performance
simulation.
(1) The analysis of energy and environmental performance in Factory A revealed that
pollution load is acceptable as per local regulations. However, the sugar recovery and
energy generation/consumption were lower than in Factory B. Some general
recommendations have been thus suggested for Factory A.
(2) Three options for Factory A, namely a piping/pump/motor optimized system, hydraulic
drives for milling tandem, and a diffuser for sugar extraction, were considered for further
technical and financial analysis. Implementing these options would increase revenue
through reduction of bagasse consumption, i.e. by-product valorization. Optimizing the
piping/ pump/ motor system is financially viable under retrofitting condition. Changing the
mill steam turbo-drives to hydraulic drives and milling tandem to diffuser are preferable
options under replacement condition.
(3) The monitoring and reporting system of Factory B was studied and suggestions made,
which will facilitate easy monit01ing department wise through tools in a user-friendly
manner. The analysis has been described using data of Factory A, which clearly highlights
the improvements suggested. |
