Abstract

Greenmill Water Corporation (GWC) is located at Malambing st. Jubileeville Barangay. Masaya, Bay, Laguna. It is a producer of bottled purified water which it sells to distributors and retailers in the country. The company produces purified or mineral water which it bottles in different sizes. Process waste within the company reduces efficiency, productivity and increases cost. In GWC, a large amount of waste water is being generated, which was found to be the largest waste contributor. Waste water constituted 24.23% of the output of the purification system. In order to reduce the amount of waste water being generated, the assignable causes of waste water in the system were identified using an Ishikawa diagram and their root causes analyzed using CNX analysis. These root causes were then classified and grouped into controllable and experimental causes. Recommendations were made to address these root causes. For the controllable root causes, the recommendations were; stricter supervision of the bottling process by the plant manager in order to enforce and monitor the adherence to SOPs; posting reminders of SOPs on the bottling line in order to remind workers; provide a step by step checklist for the setup of the purification section in order to eliminate mistakes in setup procedures; giving a refresher course on SOPs in the bottling line and to educate workers on the importance of SOPs; regular checking and calibration of the Polyethylene terephthalate (PET) bottle filling machine so that it fills the bottle up to the brim. For experimental factors the recommendations given were; quarterly audits of the supplier to ensure that PET bottles are clean and ready for bottling upon delivery; installment of timed auto shutoff valve to 5 gallon filling hose to eliminate overfilling of bottles; to add queue in between the final rinsing and filling of 5 gallon bottles so that the worker would not perform both tasks at the same time; and to implement daily inspection and maintenance of tank and pipes system to reduce and prevent leakages from occurring in the system. The above recommendations will require an initial investment of PhP 12,031 and an annual cost of PhP 10,031, but will result to an annual savings of PhP 180,872. A 10 year cash flow projection with 12% MARR, resulted to an NPV of PhP 676,853.
