About Medium Industrial Factory in Malaysia

Medium industries in Malaysia have capital investments which are in between light and heavy industries. A buffer zone, which is the area or distance between industries and residential areas, is introduced to distance the residential area from the area of activity to reduce the exposure to pollution.

Figure 1: Buffer Zone between Industrial Area and Residential Area

The buffer zones vary based on the specific activity carried out in the industry itself. Below are some examples of a few general activities which can be categorized under the Medium Industry. There will be overlapping of activities of light, medium and heavy industries but the categorisations are mainly based on the scale of the activity itself.

A primary buffer zone is an area or distance which is located outside the designated area for the project or proposed activity. The medium industry has a buffer zone that has the size which is smaller than the heavy industry and larger than the light industry. The table shown below shows the criteria for an industry to be considered as light industry and the minimum buffer zone for it:

CategoryIndustry/Activity DescriptionPrimary buffer zone requirement
MediumModerate pollution potential and risk due to burning, explosion, and/or hazardous chemicals Moderate air pollution potential (including odour) from low levels of residual air pollutants Moderate potential for emission of greenhouse gases and/or ozone depleting substances Moderate noise and/or vibration with no significant residual impactGenerate significant quantities of wastewater containing low levels of residual pollutants Generate scheduled wastes which are mostly readily treated or managed within prescribed facilities.Greater or equal to 150 m. Buffer distance for specific processes or polluting sources which are difficult to control effectively may require greater buffer distances. Actual buffer is to be determined by modeling studies where necessary.
