Global warming and increased pollution from all aspect of business activities highlight the importance of green management for firms operating in Nigeria and worldwide. More so, sustainable development practices is one of the elements that contributes directly or indirectly to business value. As the Nigerian population and its industries continue to grow, the problem of proper waste disposal becomes increasingly difficult. Products of the manufacturing process amplify the need for improved waste disposal. Efficiency is sometimes pursued at the expense of environmental sustainability. To produce as much as possible in the most cost-effective manner, manufacturers may adopt practices that appear to be cheap but are actually resource-intensive in the long run. The perspectives on manufacturing companies operations have expanded from economic to environmental and social aspects in current trends. Manufacturing companies are not only aiming to improve operations in terms of flexibility, delivery, quality, and cost, but also attempting to be competitive in terms of economic, environmental and social issues. Hence understating sustainable developmental practices is necessary and should be prioritized in the decision-making processes by company management.
