Mwanza. Tanzania has been able to reduce the use of Cloroflourocarbons (CFC) chemicals which affect the Ozone layer by 86 percent from 254 tonnes in 1999 to 35.8 in 2009. Speaking during the commemoration of the International Ozone Day which was officially marked in the country yesterday, the Mwanza Regional Administrative Secretary, Ms Doroth Mwanyika said the success was achieved as a result of the implementation of the Vienna Convention and Montreal Protocol. Tanzania is a signatory to the Vienna Convention of 1985 and the Montreal Protocol of September 1987 together with its amendments of London in 1993. To mark the day, Ms Dorothy through her representative Elias Makoyi, the Nyamagana District administrative secretary inaugurated the Refrigeration Recovery and Recycling Centre recently established at the Vocational Education and Training Authority (VETA) centre in Mwanza. The Mwanza centre will be the first to offer training on the refrigerant recovery and recycling education out of the five centres of Dar es Salaam, Kigoma, Mbeya and Zanzibar. According to Ms Mwanyika, the significant reduction of the CFC in the country was heavily contributed by the change of technology by three factories. She named them as Mansoor Daya, Ply Foam and African Enterprises all of Dar es Salaam. The success has also been contributed by the fact that most of the new big houses no longer use air conditions using CFC, she said. She said the remaining usage of CFC in the country is shared by 50 percent in businesses and factories while another 50 percent is in household equipments. She said the situation is caused by several challenges which include importation of used refrigerators and air conditions which use CFC. In order to make sure that CFC chemicals are no longer affecting the Ozone layer in accordance to the Montreal Protocol and its London amendments, the government through the Vice Presidents Office is implementing a national programme called Terminal Phase Out Management Plan. The project is funded by the government together with the Vienna Convention fund called Multilateral Fund and aims at renmoving CFC by 100 percent by January 2010 and making sure that the project is sustainable there after. After the Ozone layer is destroyed by the CFC chemicals it allows ultraviolet B radiation to reach the face of the earth causing skin cancer, blindness as well as reduction of the bodys ability to protect itself against diseases especially on children.
