Marsh gas in Taiwan mainly derives from the wastewater treatment of the animal husbandry and pig farming, the household sewage, and landfills. If marsh gas can be recycled, it not only can gain rewards but also reduce the emission of the greenhouse gas. In fact, many industries, such as landfills, pig farming, and food manufacturing, have had equipment to deal with marsh gas and makes it become biogas power generation. Some other businessmen even have channeled marsh gas to the boiler that emerges steam as fuel directly to supply their businesses. Sanjuku Power Generation was set up in 1999 and it was the first biogas power generation in Taiwan. However, adhere to the goal of “zero waste" plan, calling for reducing, reusing and recycling nearly all the waste, waste here decreases sharply. Consequently, the marsh gas from landfills is reduced year by year. Marsh gas power generation has already been less than one tenth of the power at the peak period of 2012. Because the marsh gas is produced under 1 million steres a year, the expense of power generation is unable to make ends meet. As a result, the power plant is removed and power generation is operated by the commissioned companies.
