With the support of the joint Research Cooperation Program of the Bureau of International Cooperation, Chinese Academy of Sciences (CAS) and the Alliance of National and International Science Organizations for the Belt and Road Regions (ANSO) (Project: ANSO-CR-KP-2021-08, Technical Research and Application Demonstration for Sustainable Development of Biomass Waste Resources in Southeast Asian Countries), and on the invitation of the international partner, PT. Fuhai Industrial Estate, Prof. Wang Yin, the project leader, led a delegation on a visit to Indonesia from July 21 to 25, 2025.
On July 22, the research team held discussions with the representatives from their Indonesian partners: PT. Fuhai Industrial Estate, Mr. Vicko Suprijatna (Consultant of PT. IRMASULINDO), and Ms. Clarin Sukri (Manager of PT. Duo Multi Solusindo). The meeting focused on challenges and prospects for applying and promoting activated carbon water purification technology in Indonesia and the feasibility of expanding biochar applications beyond water treatment to mitigate soil contamination and enhance soil quality. In addition, two water purifiers were presented to PT. Fuhai Industrial Estate for trial use. The activated carbon filter technology of these water purifiers was provided by the Institute of Urban Environment, Chinese Academy of Sciences.
On July 23, the research team traveled to Mendalo Darat and met with local officials, including Regent Head Dede Noviyanto and Village Head Bambang Santoso. During the visit, the delegation demonstrated self-developed water purifiers and donated two purifiers – one to the village administration office and one to the household of resident Ms. Laura for free trial use. After on-site water testing, the tap water treated by purifiers became visibly clear and had a slightly sweet taste, earning strong approval from local officials and residents. Both District Head and Village Head expressed strong willingness for continued cooperation, emphasizing the need to scale up water purification capacity to meet urgent local demand for clean drinking water. Prof. Wang Yin is committed to further optimizing the technology and reducing costs to provide sustainable technological solutions for improving local water quality.

On July 24, accompanied by a representative from PT. At Fuhai Industrial Estate, the research team visited PT. Indofurnace. They toured the activated carbon line and held detailed discussions on current production processes, market demand, raw material supply, and the feasibility of cooperating in high-value deep processing of coconut shell-activated carbon.

On the morning of July 25, the research team met with Secretary-General Zhou Weiliang and Vice Chairman Lin Songshi of the Indonesian Chinese Chamber of Commerce, along with Indonesia Daily Editorial Advisor Qiu Sifeng. The delegation briefed them on the visit’s objectives and outcomes. Secretary-General Zhou commended the productive contributions of the Institute of Urban Environment, Chinese Academy of Sciences, to biomass and water quality research in Indonesia, supporting further scientific collaboration for environmental protection in Indonesia and globally. That afternoon, the delegation visited BRIN. Following in-depth discussions with Dr. Hens Saputra’s team, both parties agreed to jointly apply for Sino-Indonesian intergovernmental projects. The delegation donated a water purifier to BRIN.

The visit has reinforced Sino-Indonesian intergovernmental collaboration, accelerated the deployment of Chinese technology in Belt and Road nations, and advanced Indonesia’s development of secure drinking water systems, jointly advancing public welfare projects.
