Another example is a food waste recycling system developed by a multidisciplinary team of government agencies, corporations and academia, this is similar to an ongoing Japanese project related to methane fermentation and high-speed composting technology with waste recovery logistics and multi-stakeholder collaboration. For example, continuous exchanges of knowledge and practices on an RCS between Japan and Viet Nam yield significant academic and practical fruits in the IR3S research project. A Vietnamese research team has examined typical ecosystem services in the wetland conservancy of the Mekong River delta (Triet and Caines, 2007).
