The portion of kitchen waste in the municipal solid waste was estimated to 25% in Taiwan, most of which are perishable and result in disagreeable odor because of high content of biodegradable matters. Obviously it is not an adequate strategy to dump in landfill because of high concentration in leaching wastewater. On the other hand, incineration will result in the decreasing of energy recovery because of low heating values. Despite the drawback in the treatment, rich organic content of kitchen waste was taken as valuable resources to be recovered. Recently EPA has spent a lot of budget to encourage the local Counties and Cities to recover the kitchen waste for reutilization, most of those efforts were focus in pig feeding (about 75%) and composting process (about 25%). From the implementation of this project, the technical and economic effectives were evaluated through the comparison of several kind of utilization. Meanwhile, by the assessment of the local Environment Protection Bureaus, variable approaches were found to improve the recycling ratio, and was amount to 900 tons per day. Base on the achievements mentioned above, the strategies of kitchen waste recycling were proposed as a guideline for further promotion.
