**2. Literature review**

Malaysian rubber industry has always been regarded as an environmentally sustainable industry. Rubber trees play an important role as a carbon dioxide sequester from the atmosphere at a rate comparable to if not better than the natural forest [5]. After the process of falling down, rubber trees are converted into renewable rubber wood for furniture based industry. The term renewable or environmentally friendly associated with the rubber wood arises from the fact that the rubber wood represents a relatively sustainable alternative as compared to the tropical woods extracted from natural forest [6].
