From the perspective of using rubberwood as fuel, it is apparent that rubberwood is a promising candidate as an alternative renewable energy source. In addition, the conversion technologies such as combustion, pyrolysisand gasification have been used to generate energy from rubberwood biomass. In fact, Lim et al. identified that the energy content of rubberwood can be as high as about 68.61 million gigajoules (GJ) per year or 40.04 GJ per hectare per year. Based on this estimation of energy content, Table 3 summarizes the potential energy production that could be realized from the rubberwood waste available for fuel.
Table 1. Estimation of Energy Generation from Rubberwood Waste as Fuel
As shown in Table 1, the energy supply from rubberwood waste reduced significantly owing to the reduction in rubber cultivation area, which consequently decreased the available amount of rubberwood biomass.
In Thailand, there is a furniture factory that produces rubber wood. Every year, a large amount of rubber wood is used for furniture production. Due to poor production management, the factory cannot make ends meet. Coincidentally, ZBG company inspected the rubber wood production line in Thailand, and the head of the factory invited ZBG engineers to visit and guide.
In the factory, ZBG engineers found that the boilers used for drying wood on the production line were coal-fired boilers, which were expensive, and the bark and other wastes generated in the wood production process were disposed of at a low price to the plywood factory. This invisibly increases a lot of running costs.
