Cleaner production for environmental conscious manufacturing in the foundry industry

The purpose of the paper is to illustrate application of the cleaner production concept so as to incorporate environmental protection into business performance. The study analyses areas pertaining to the foundry industry that impact negatively on the environment leading to unsustainable resource utilisation and suggests options for promoting sustainable development within the industry, with specific focus on a foundry in a lower income country (LIC).

Data were collected using the cleaner production (CP) Methodology. Pre‐assessment and assessment was carried out and options generated. The options included both low cost and capital intensive approaches.

The paper finds that the CP approach adopted provides clear guidance for generating options and can be used as a practical basis for managerial decision making and policy formulation. Of major concern is resource depletion and pollution associated with the foundry processes. Used resin sand contains toxic chemicals cause leaching and as such, reclamation of resin sand is suggested. There is need for low income countries (LIC's) to identify the best available technologies (BAT's) that are available within the foundry industry and take these aboard or better still improve on them.

This research developed environmental options that can be applied in the foundry industry. However, it can be said that the findings may have limited global application since the analysis was carried out at one Foundry Company.

The paper focuses on a single foundry factory, since the case study approach was used. As such, environmental indicators and options may vary, since the processes from one foundry to another are bound to differ.

This paper is an attempt at combining theoretical and practical ideas to cover the scope of sustainable manufacturing in the setting of a developing country with a view to identify the lessons that can be learnt and to identify the points of departure when compared with studies done elsewhere. The work informs cleaner production assessment at any level, with a focus of production experiences in the foundry industry in a lower technology, developing economy that is less industrialized. The paper establishes a framework of options that can be applied in the foundry industry and other pollution‐intensive industries.
