Dr Sun Xiaolong is the Founder and Managing Director of Zerowaste Asia (ZA). He has more than 20 years of research and industrial experience in waste, wastewater, and materials science. He is proficient in waste and wastewater treatment, waste-to-resource management, environmental impact assessment, green construction materials, and materials science.
Together with his team in ZA, he has completed numerous industrial, research and development, and consultancy projects in waste and wastewater treatment as well as waste-to-resource management. His team collaborated with NEA to conduct Singapore's first comprehensive study on incineration bottom ash (IBA) utilisation in 2012 and was contracted by NEA to treat IBA into NEWSand. Dr Sun has provided solutions to challenging waste and wastewater treatment for various industries with pollutants including heavy metals, organic pollutants, fluoride, cyanide, phenolic compounds, chemical oxygen demand (COD), total suspended solids (TSS), colour, ammonia nitrogen, etc.
Dr Sun obtained his PhD in Materials Science and Engineering from NTU. He is the inventor of 14 patents and author of numerous research publications on environmental technologies. He is familiar with toxicity characteristic leaching procedure (TCLP), as well as environmental standards in Singapore, China and the European Union.
Designed the process and chemical reagent to treat a type of complex heavy metal wastewater from electronic industry. The wastewater contains 2 ppm of complexed Nickel, which could not be treated to meet 0.1 ppm standard by other technologies at a low cost. Dr Sun then designed a new treatment process and chemical based on the client's requirements, which is simpler and more cost-effective as well as enabling the process to continue running and meeting the discharge standards.
Worked with local and overseas governmental agencies and incineration plants to treat their incineration bottom ash and incineration fly ash, e.g. led and provided proprietary incineration bottom ash treatment solution to the NEWSand project. Conducted environmental impact assessment and leaching studies to recommend possible disposal or utilisation channels of the treated incineration ash. Established environmental standards for waste treatment and waste-to-resource.
