The seminar began with an opening statement by Associate Professor Naraphon Chan-o-cha, remarks by H.E. Mr. Warawut Silpa-a-cha, Minister of Natural Resources and Environment, representatives from the youth, the government sector, the private sector and the public, after which the spouses of leaders engaged in an interactive discussion and shared best practices on waste management.
