Interest rising in CNG as alternative to gas, diesel

In Uncategorized on April 5, 2010 at 9:27 am

As part of efforts to reduce exhaust fumes from industries and vehicles, more Vietnamese businesses and agencies have shown interest in switching to Compressed Natural Gas (CNG) to replace gasoline, diesel and propane.

However, converting to the more environmentally friendly fossil fuel has been slow due to the cost of converting old systems to those that can accommodate CNG.


According to reports from the Ministry of Planning and Investment’s Clean Tech Fund, harmful fumes released from industries this year could account for up to 33 percent of total emissions in the country. Meanwhile, electricity production could account for up to 27 percent of total emissions and vehicles could account for 24 percent.


Last year, bus operators in Ho Chi Minh City expressed interest in switching to CNG as the gas is also more cost-effective than regular fuel.


The Sai Gon Passenger Transport Company and HCMC Bus Cooperative Alliance each imported one CNG bus. The former company has also cooperated with PV Gas South Company to invest in special CNG stations and transport vehicles to provide the buses with CNG.


One station has now been built in the southern coastal province of Ba Ria-Vung Tau and is able to meet the fuel demand of 500 buses.


Another station has also been built in the Sai Gon Passenger Transport Company’s campus in District1, HCMC. Five trailers with a capacity to transport 3,760 kilograms of CNG each, are ready for operation.


The Ministry of Transport, its department in HCMC, and CNG providers have also held three seminars to introduce plans for implementing more CNG technology in Vietnam.


Meanwhile, the ministries of Natural Resources and Environment, and Planning and Investment also view the use of CNG as helping the country to cope with climate change.


According to Dr. Nguyen Trung Viet from the HCMC Department of Natural Resources and Environment, the Asian Development Bank (ADB) and other environmental organizations have funded $250 million for a program to increase the use of CNG in Vietnam.


Companies ask for assistance


Le Trung Tinh from the HCMC Department of Transport said that many transport businesses are hesitant about switching to CNG because of the initial cost involved in switching to a system able to accommodate the gas.


Changing engine types would save fuel costs, but the vehicle quality would reduce, he said.


Importing a fleet of new CNG buses is too costly for most operators with the vehicle prices double those of standard gasoline-using ones.


The Sai Gon Passenger Transport Company on March 29 sent the Ministry of Planning and Investment a proposal asking the ministry to approach Prime Minister Nguyen Tan Dung about approving a tax exemption on imported CNG bus engine systems.


The company says it is now waiting for a reply from the Government.


Mr.Tinh said that HCMC now has about 5,000 buses with 1,300 of them in need of modernization.


If authorities help businesses pay for clean-energy buses, the city would be able to convert 1,300 of the buses into more environmentally friendly vehicles.

Conference members advocate alternative medicine


QĐND – Friday, February 26, 2010, 22:23 (GMT+7)

The benefits of complementary and alternative medicine in serving public health were highlighted by experts at a conference held in HCM City on Feb. 24.


At the conference held by the UNESCI Centre for Public Health, they said this branch of medicine, a group of diverse medical and health care systems, practices, and products that are not generally considered part of conventional medicine, give patients more health care choices.


Alternative medicine has also become popular in industrially advanced countries including the US, they noted.


A survey conducted by the National Centre for Complementary and Alternative Medicine in the US found 74.6 percent of its residents used complementary and alternative medicine therapies and 54.9 percent used it in conjunction with western medicine.


Most of them use the complementary and alternative medicine to treat and prevent problems involving their joints.


Another study conducted by the Health Forum under the American Hospitals Association also showed that many hospitals in the US are providing complementary and alternative medicine therapies to meet patients’ demands.


In 2008, 37 percent of hospitals in the US used these therapies, an increase of 26.5 percent over 2005.


Complementary and alternative medicine has been applied widely in Canada, the UK, Ireland, France, Germany and Australia, the conference heard.


Experts at the conference also noted that “Universal Energy”, one of the complementary and alternative medicine therapies, has also been applied in other fields including agriculture in Vietnam in order to limit the use of chemical fertilisers and insecticides to protect farmers’ health as well as the natural environment.

VEA orders HVS to use slag alternative

In Vietnam Society on January 13, 2010 at 12:27 pm








Mr. Le Ke Son

Deputy head of the Vietnam Environment Administration (VEA), Le Ke Son, January 12 said inspectors had asked the Hyundai Vinashin Shipyard Co. (HVS) to use alternatives to toxic copper slag when cleaning and repairing ships.


Speaking to Sai Gon Giai Phong, Mr. Son said inspectors had ordered HVS to immediately begin using steel balls or water as alternatives to the slag, known as nix grains, to remove rust and paint from its ships.


Inspectors asked officials in the central province of Khanh Hoa where HVS is based, to support the Vietnam-Korea joint venture in maintaining production in times of economic hardship.


Mr. Son, tasked with leading the HVS investigation, stressed that the company’s earlier production and use of 800,000 tons of nix violated environmental protection laws and had caused public concern for over a year.


The shipyard was ordered last March by the VEA [a division of the Ministry of Natural Resources and Environment (MoNRE)], the environment police, and Ministry of Transport inspectors to take environmental protection measures.


Mr. Son said that HVS would still be responsible for the 800,000 tons of previously produced nix and the company must commit to building a waste treatment facility.


The VEA deputy head said that while copper slag was a more efficient material for refurbishing ships, residents’ health and the environment could not be sacrificed for economic benefits.


Mr. Son reiterated that nix grain is not an illegal substance; therefore, HVS would be allowed to use it in the future if it ensured a good storage area and came up with effective nix treatment measures.


The provincial Department of Natural Resources and Environment must conduct regular environmental monitoring and impose severe penalties if violations are found, Mr. Son added.

Also on January 12, HVS sent a document to the media explaining its use of nix. It said in the last two years, HVS has tried to reduce the amount of nix used to repair ships.


However, due to a drop in clients as a result of the economic crisis, over 1,000 of HVS’ 3,600 workers had to be laid off. HVS says it therefore had no choice but to import more than 20,000 tons of nix to increase the efficiency of its ship cleaning and maintain profits. The company said it would not buy more nix in the future.


A treatment factory for the slag is planned to begin construction in March, 2011 with a capacity of 300,000 tons a year.






Prime Minister Nguyen Tan Dung has asked the Ministry of Natural Resources and Environment (MoNRE) to focus on improving environmental management mechanisms and policies on sustainable protection of the environment.

MoNRE needs to immediately prioritize safe water supplies for both urban and rural areas, Mr. Dung said while addressing a year-end conference on January 12 in Hanoi to review MoNRE work in 2009 and outline plans for 2010.

He urged the ministry to pay due attention to inspecting and examining rivers nationwide to detect potential pollution problems early and deal promptly with polluters.

Regarding the planning and use of land, MoNRE should better its management and use land resources in an economically efficient and appropriate manner, PM Dung said.

He requested that MoNRE work to protect wet-rice farm land, and specialized and protective forests, to help ensure both food security and environmental protection.

MoNRE said it completed almost all targets set for 2009, notably the issuance of a resolution on stepping up economization of the natural resources and environment sector.
