Attending the “International Conference on Solid Waste 2015: Knowledge Transfer for Sustainable Resource Management”

The concept of “Wastes are misplaced resources” is already conceived; but the realization in a systematical way around the world is yet to begin. From the last decade, the sustainability issues of both management and treatment of solid wastes constitute the heart of the problem and embrace acceptance by many countries. Now it is the time to fuse the sustainability and effective resource utilization. Most importantly, time is crucial and the human are stamping their authority and challenging the resilience of the Mother Nature knowingly or unknowingly. Therefore, every stakeholders need to join hands to protect our Earth through sustainable use and management of resources.  


Sharing and knowledge transfer can provide impetus on reducing the trial and error time required at different parts of the world on a specific issue. Solid waste management is a collective effort and will be efficient and sustainable if stakeholders understand their own responsibility and accountability of preserving the environment to our future generations. The “International Conference on Solid Waste 2015: Knowledge Transfer for Sustainable Resource Management” (ICSWHK2015) definitely provide a great opportunity and platform to exchange the views, visions, and experiences on waste treatment technology and sustainable waste management among scientists, academics, practitioners and policy makers from all over the world. 

 
Attending this conference, Dr. Nguyen Vo Chau Ngan - PostDoctoral from SubProM project - on behalf of research team had an oral presentation with the title of  “Paddy straw application for energy production to reduce in situ straw burning in the Mekong Delta of Vietnam”. In this research, lab-scale 21 L batch anaerobic digesters were set up to ferment paddy straw in 60 continuous days. Straw was grinded in different small-sizes and pre-treated with digester’s effluent for 5 days. The temperature, pH, and redox recorded daily in most of the treatments were in good conditions for methanogen. The gas yield from the treatments of rice straw 0.2 cm was 760 L/kg ODMfermented, 0.5 cm - 756 L/kg ODMfermented, and 1.0 cm - 764 L/kg ODMfermented which was higher than the treatments of 0.05 cm - 677 L/kg ODMfermented and original size - 698 L/kg ODMfermented. The CH4 content in all treatments got more than 45% after three weeks which good enough for cooking purpose. The results confirm that the anaerobic practice could produce biogas from paddy straw and this can help reduce the local practice of burning straw on field. More straw apply for biogas production, less straw in situ burning that eliminate greenhouse gases emission.
