Lean Energy Consideration of a Nigerian Sawmill Facility

Abstract

Leanness can be defined as minimization of waste. Waste depletes resources but does not have any improvement on the values of the products. It can occur in many forms and in many places. Lean methods help to reduce waste. Waste can be minimised by isolating and eliminating those activities that have no value adding effect on products. Lean programs create a cultural and people-oriented transformation by educating entire organizations on how to identify hidden wastes and empowering each employee to enhance the quality of production. Lean energy can be achieved by exposing the aspects that contribute to the supplementary energy component. This work considers isolating the energy wasting components of machines used in log processing by analyzing the entire energy use pattern. In the log processing industry sector, energy is consumed for a wide range of activities such as sawing, lighting, saw sharpening and other maintenance activities. The sawmill facility under investigation is the electric motor. The entire machines used in the production process have electric motors as their prime mover. The power rating of the electrical devices and capacity of each unit were collected from the personnel in charge. The production processes were monitored and measurements of necessary parameters were taken with the aid of the following instruments: Wattmeter, digital laser Tachometer, stop watch and tape; data were recorded for weeks depending on the size of the site being considered. The study showed that a 10hp motor replacement would likely perform the sawmilling operation on the band saws more efficiently.
