1. Impact of Introducing a New Plant/Equipment on the Materials
Balance Principle (10 Marks)
(a) Description
The materials balance principle in environmental economics states that
matter and energy cannot be created or destroyed, only transformed.
This principle is derived from the laws of thermodynamics. In economic
production, raw materials extracted from the environment are
transformed into goods and residual waste. Therefore, whatever enters
the production system must either leave as useful output or as waste
(solid, liquid, or gaseous emissions).
When a new plant or new equipment is introduced, it affects the
materials balance in different ways. If the equipment is more efficient, it
reduces waste per unit of output, meaning fewer emissions are released
into the environment. For example, installing cleaner production
technology can lower pollution intensity while maintaining production
levels. This improves environmental performance without necessarily
reducing output.
However, if the new plant increases production capacity, total material
input may rise. Even if the plant is more efficient per unit, overall
pollution may increase due to higher total output (known as the scale
effect). Thus, the materials balance principle shows that environmental
impact depends on both efficiency and production scale.
