Discussion in the research unit of Bio-resource colloid engineering has confirmed the validity of colloid and interface science for interdisciplinary discussion. That is, colloid science can be an important basis for the research development in water, soil, food, pulp and paper, waste and resources management. In order to make full use of the results along the mission for next generation such as realization of carbon neutral society, SDGs, counter measure against microplastic pollution, the way of thinking in the field of civil and environmental engineering is considered to be practically useful. With this conclusion, we have decided to collaborate to organize joint session with grope of civil engineering in Delft University of Technology that is recently active as MUDNET in Europe. This opportunity will lead to construct a new global forum to enforce the knowledge of colloid engineering for the next generation.
