Effectively Applying Japanese Waste Treatment Technology

Hai Phong Urenco is responsible for ensuring environmental sanitation, collecting and treating waste in Hai Phong City. Every day, the company collects and treats 900 - 1,000 tonnes of rubbish and 300 cubic metres of garbage leachate, manages and operates a solid waste treatment facility with a daily capacity of 150 tonnes together with Trang Cat and Dinh Vu treatment facilities. These are huge workloads and require timely, close and accurate operation. For this reason, Hai Phong Urenco has applied modern technologies to all stages of operation.

 

The company uses Google Maps application to measure and estimate workload, manpower and vehicles for waste collection in every route in the city. At the same time, Hai Phong Urenco also monitors activities in subordinate units and individuals through job descriptions to have timely guidance. All information, documents and records are updated and synced across all electronic devices and phones. Data are processed by the Digitalised Meeting Room. By applying this technology, the employees are assigned tasks logically and scientifically.

 

Japan’s ODA-funded projects have helped the company with more professional experience in waste treatment, thus improving the living environment for citizens. Mr Le Ngoc Tru, General Director of Hai Phong Urenco, said, “Defining modern technological application is the key to solving environmental dilemmas, we have constantly learned and boosted cooperation with foreign organisations and partners. We have successfully implemented some projects, including solid waste - to - compost fertiliser treatment facility (South Korea), landfill dumpsite using Fukuoka methods (Japan), JICA-funded medical waste incinerator (Japan), and waste classification pilot project (France). The company has carried out five Japanese projects and planned to acquire more technologies from Japan.”

The Fukuoka semi-aerobic landfill technology is part of environmental cooperation and assistance programme between the Fukuoka University, Fukuoka Environment Agency, and Hai Phong City. This method is widely used in Japan and 12 countries in the region. This method collects and recirculates leachate by a perforated drain pipe system simply installed at the bottom of the landfill site. The surface of the landfill has aerobic systems to facilitate microbial decomposition and reduce methane gas concentration in the landfill up to 45 percent. With a lot of cultural similarities and being industrial cities, Hai Phong Urenco had positive achievements after it carried out in Hai Phong City. Data collected from Dinh Vu dumpsite showed that carbon dioxide index fell 30.4 percent (when Fukuoka method is not in use) to 8 percent and methane gas index from 67 percent to 6 percent. COD and BOD5 indices in wastewater dropped from 80 percent to 20 percent. Wastes are decomposed faster.

 

Besides, to treat increasing hazardous medical wastes from hospitals, Hai Phong Urenco has cooperated closely with the Japan International Cooperation Agency (JICA) to carry out the “medical waste incinerator” project with an hourly capacity of 200 kilos. The project will use IVMS-200 incinerator for processing hazardous medical and industrial wastes designed, fabricated, installed and test-run by Irisan Kizai Corporation (Japan). This incinerator uses advanced Japanese technology. This technology treats medical wastes and hazardous wastes by air-blowing method which consumes less fuel and saves energy. Emissions meet Japanese environmental standards.

 

To continuously improve professional expertise, the company has sent its specialists to cities with advanced waste treatment technologies such as Tokyo, Kyoto and Fukuoka. Hai Phong Urenco also encourages its employees to suggest initiatives to improve environment and treat wastes. To date, 40 scientific themes have been submitted, with most being very practical and innovative. This not only helps employees promote their expertise but also help better environmental protection.

 

Hai Phong Urenco has overcome all difficulties and challenges to fulfil their heavy tasks of protecting the environment of Hai Phong and contributing to community health improvement.
