Speech Title: Environmental Science Approached Closed Agro-waste Loop Enhancing Circularity

Circularity refers to a circular economy aimed at eliminating waste and continual use as a resource for another product. Circular systems employ reduce, reuse, and recycling to create a close-loop system leading to the use of resource inputs with less creation of waste, pollution and carbon emissions. Agro-waste can be utilized as material supply, nutrient elements for plant growth, carbon sequestration into the soil, capture CO2 via photosynthesis and accumulation of CO2 as carbon fixed in the plant biomass. Besides, become food for another process, either a by-product or recovered resource for another industrial process, or regenerative resources for nature, e.g., compost. Green productivity as coined by acceptance waste equals food. The innovative technologies have to be deployed safely and managed their risks properly. Closed-loop systems are the conceptualization of integrated approach to manage the entire life cycle of resources as a philosophy driven zero waste signified waste as a resource lead to developing technologies and innovations about turning the materials recovered from waste into new products provided similar environmental quality and benefits. Fact-finding through the environmental science approach and realized how the natural environment is treated brings about clarify and open-ended the value loaded natural environment with accountability in the working process and enhancing circularity.

Keynote Speaker III

Assoc. Prof. Win Chaeychomsri
Kasetsart University, Bangkok, Thailand

Assoc. Prof. Win Chaeychomsri received a Bachelor’s Degree in Biology, Master’s Degree in Tropical Medicine, and Doctoral Degree in Animal Biotechnology. He has been a lecturer in Department of Zoology, Faculty of Science, Kasetsart University since 1994. He is an outstanding lecturer in research and innovation. His current research interests are in the fields of parasitology, immunology and animal biotechnology. He has authored books, published more than 100 technical papers in various journals and conference proceedings. He gets 3 petty patents and 2 patents. These petty patents and patents involve the production technology of freeze-dried crocodile blood that will be used as dietary supplement for health improvement. In addition, he is in an ongoing effort trying to develop new products from crocodile bile and bone for health maintenance and also crocodile oil products for health promotion and skin treatment.
