Abstract

This report provides informative discussion on the different processes involved in raw and refine sugar production. It also provides calculations on material and steam balance for raw house and refinery. Based on the computed material and steam balance, the PSTC is 1.4421 while the refining yield is 1.2045. The special topic of this field report is the waste management scheme LSC employs in their operation. This study shows that LSC follows the waste management hierarchy where the priority is waste minimization followed by waste treatment and disposal. In waste minimization, they use different techniques and operating procedure such as ash clarifier, water softening treatment and waste reduction. For wastewater treatment, they use biological treatment where microorganisms are utilized to reduce organic substances. Lastly for waste disposal, majority of the waste are distributed to the planters since most of the waste may be used as soil conditioning. It is recommended to analyse the each section of the waste water treatment to evaluate the effectiveness of each step of the treatment. This can be achieved determining the percent waste treated in each step by getting the quality of the input and output stream.
