STUDY OF WASTE MANAGEMENT FOR A SUGAR MANUFACTURING PLANT

Abstract

The present project report deals with the study of waste management for reduction, segregation, collection, storage, recycling and disposal of sugar wastes in sugar manufacturing plant. This study is carried out in Mahalaxmi Sugar Mill, Iqbalpur, Distt Hardwar. Importance of waste management in the context of sugar manufacturing plant is highlighted. The study is intended to illustrate . how the productivity improvement and higher effectiveness is achieved. The study also illustrates the concept of productivity measurement. By rectifying the defects of individual units and making modifications and alterations in the existing machinery, the efficiency of equipment and the capacity of plant would be increased. The total losses would considerably reduce thereby increasing the productivity. In order to identify weak areas of the system, MBO approach has been adopted for carrying out productivity analysis. The wastivity indices for different stages of sugar manufacturing have been calculated. Also the productivity indices for different subsystems in Mahalaxmi Sugar Mill and overall productivity index for the plant have been calculated. Results show that wastivity is low at Syrup Sulphitor and high at "C" Centrifugal Machines II and at evaporator. The reason for high wastivity at "C" Centrifugal Machines II is that here outputs are "C" light molasses and "C" sugar, both being wastes although "C" light molasses is fed back into "C" vacuum pans and "C" sugar is fed back to Syrup Sulphitor for their further processing. The reason for high wastivity at evaporator is that more sugar particles pass through water vapour due to entrainment. Overall plant productivity comes out to be 0.52 which is low. Further analysis reveals weak areas where effectiveness improvements are
