Course description and aims

This course provides the knowledge concerning the concept of cascaded use of resources for the optimization of resource use efficiency, and the methodologies for the production of materials and energy to minimize waste materials and energy.

Student learning outcomes

At the end of this course, students will be able to: 1) understand the methodologies for maximizing the resource use efficiency through the cascade utilization of resources and utilization of renewable resources; 2) understand the concept for minimizing the waste production by utilizing wastes as a raw material for other processes; 3) understand the utilization of resources and wastes that contribute to the construction of a recycling-oriented society by combining the above-mentioned two items.


Biomass, Biorefining, Biogas, Composting, Cascade use of biomass

Competencies that will be developed

Intercultural skills Communication skills Specialist skills Critical thinking skills Practical and/or problem-solving skills

Class flow

In the first half of the class, a summary of the previous lecture are provided. In the latter half, the main points are discussed in detail. Students are asked to provide solutions to some of the questions that have been posed as necessary. Always check the required learning for each class and be sure to complete them as part of preparation and review.

Course schedule/Required learning

  Course schedule Required learning
Class 1 Biomass resorces and wastes Understand the importance of the effective use of the biomass resource and waste that are abundantly present on the earth
Class 2 Biorefining, production of chemicals from biomass resorces Explain the production of chemicals as an example of biorefining which is a conversion technology for biomass
Class 3 Biorefining, production of fuels from biomass resources Explain the present state of the art and production principles for bioenergy which is attracting growing interest as one example of biorefining
Class 4 Wastewater treatment, fermentative biogas production Understand the principle of conversion technology used to produce biogas from wastewater as a raw material
Class 5 Wastewater treatment, new innovation in biogas production Explain new technologies for monitoring the performance of biogas plant using molecular biology
Class 6 Solid waste utilization, compost suppressing plant pathogens Understand the production procedure for compost which suppresses plant diseases among the applications of solid waste composting
Class 7 Solid waste utilization, production of high quality biofertilizer Explain the principle of the methods for utilizing molecular biology for the reproducible production of compost with high fertilizing effects
Class 8 Cascade utilization of resources and wastes for a sustainable society Understand the mechanisms for minimizing waste through the combination of various elemental technologies and reproduction of raw materials


No textbook is set. Handouts will be distributed at the beginning of every class.

Reference books, course materials, etc.

Handouts will be distributed at the beginning of class when necessary and elaborated using PowerPoint slides. PowerPoint documents that are to be used in class will be made available in advance via the OCW-i system. Students are expected to use these documents for preparation and review purposes.

Assessment criteria and methods

Learning achievement is evaluated by report.
