Cleaner Production

The reality of global warming is felt all over the world, just as the realities of the causes are known to be human activities; irrespective of their location on the globe. The manner in which the natural resources are unsustainably utilized is the root cause of such phenomenon like ozone layer depletion, acid rain global warming, loss of biodiversity and depletion of non-renewable water and energy resources.
The UNEP definition of Cleaner Production (CP) is:
“The continuous application of an integrated preventive environmental strategy to processes and products so as to reduce risk s to humans and the environment”

The main focus is an integrated waste minimization, environmental pollution prevention and sustainable development. In this sense sustainable development can be describe as:

“A development that meets the needs of the present generation without compromising the ability of future generations to meet their own needs”

Module 1: Introduction to CP and Sustainability

The term ‘Cleaner Production’ can be misunderstood and hence it is very important to start up by defining and explaining what it means. On the other hand, the term sustainability is more easily understood, but does not capture all the elements of cleaner production; it is therefore used to complement the term cleaner production.

Module 2: CP in a Broader Environmental Context

‘CP’ focuses on the production process, and continuously seeks opportunities for improving the process, particularly with the view to reducing costs. Yet the CP process itself has to take place in and should take cognisance of the legal, social and environmental context of the production process. This module will discuss of some the main issues involved in this broader context, including the Health and Safety (of workers and of surrounding communities), the immediate and possible cumulative environmental impacts of the manufacturing process, and product safety.

Module 3: CP in a Business and Social Context

In this module we will briefly introduce the concept of environmental accounting and show how it relates to cleaner production and corporate responsibility and its impact on corporate image. Environmental accounting is gradually becoming a standard accounting procedure for corporations, due to pressure from regulators, shareholders and the huge concern over the climate changes being experienced.

Module 4: The CP Cycle

This module will take you through a journ ey that is cyclic; meaning that cleaner production is not a once-off activity, but a continuous process. The new CP thinking is that there is always room for improvement be it in productions of products or service delivery. The CP cycle involves planning
and organising, identification of opportunities, prioritizing and evaluation, implementation and measurement and review. We will look at each of these activities and discuss how they are carried out.

Module 5: Application of CP Techniques

You have now acquired sufficient knowledge regarding CP and now it is time to see how these theories come together to benefit a business venture. We will consider four case studies were CP principles have been applied with great benefits.
