Evaluation of corrosion cost in some selected food and agro‐processing industries in Nigeria

Abstract

Purpose

Because of the peculiar nature of food and agro‐processing industries, the industries cannot tolerate corrosion deposits in their production lines. Hence, there is the need to account for corrosion control before and during the production operations. This is more so in Nigeria where there is little or no proper accountability of corrosion cost in all production system.

Design/methodology/approach

The industries investigated were grouped into: meat and meat product, dairy and milk, beverages and brewery, confectionery and agro‐processing centres. Questionnaires and interview pro forma were used to collect information from ten major factories/outlets in each category. The study involved the use of life cycle costing to assess corrosion management alternatives and to determine the annualized value of each option.

Findings

Among the corrosion prevention methods identified in the industries, greasing gave the least cost contribution (15.9 percent) to the total cost of corrosion prevention followed by painting (17.97 percent) and cleaning (66.14 percent) in that order, while the contribution of each corrosion maintenance method to the total cost of corrosion maintenance was, respectively, 13.08, 7.23, 20.73 and 58.96 percent for annual maintenance, repair, rehabilitation and wages of workers.

Originality/value

This study reveals some of the control measures commonly adopted for minimizing corrosion damage in some selected food and agro‐processing industries in Nigeria. It also investigated the cost implication of each measure and how it affects the present value of processing machineries in each industry. The results of the study have created a state of awareness of corrosion problems to stakeholders, which would encourage preventive actions.
