Investigation of Distributed Quantity of Chemical Substances
The investigation of distributed quantity of chemicals is to identify the types of chemical and production, import, use, export and the purpose of uses of substances and is being used as a basic data for management policy of chemicals. This began as a demonstration project in investigating the amount of chemicals distributed in 1996 and total investigation is conducted every 4 years.
The distributed quantity of chemicals in 2010 was 432.5 million tons, increased by 3.5% compared to 2006 (14/6 million tons). This also shows similar progress in the comparison analysis with a national statistic index related to crude oil imports, rate of operation in the manufacturing factory and industrial production.
The amount of chemicals produced was 289.1 million tons, increased by 0.9% compared to 2006 (286.3 million tons). The major produced substances were: crude oil (35.7 million tons), Portland cement (26.6 million tons), Bunker C (20.8 million tons), naphtha (17 million tons) and diesel (12.8 million tons), these top 5 substances accounted for 39% of the total production.
The amount of chemicals imported was 231 million tons, increased by 22% compared to 2006 (189.3 million tons). The amount of crude oil imported was decreased (4.6 million tons); however, the amount of naphtha and ferric oxide used to steel material were increased, or 2.7 million tons and 5.2 million tons, respectively.
The amount of chemicals exported were 87.6 million tons, which was increased by 51.8% compared to 2006 (50.8million tons). Major 5 exported chemicals were: crude petroleum (14.2 million tons), kerosene (6 million tons), Naphtha (5.4 million tons), xylan (6 million tons) and diesel (4.6 million tons), accounted for 41% of the total exports.
Investigation of Emissions of Chemical Substances
A Pollutant Release and Transfer Resister (PRTR) is a system that allows industry sector to present pollutant or substance released to air, water system or environment while treating chemical substances in the site and to find out the amount of release outside for recycling or treatment and report to the government. The government collects these data and discloses to the public. This emission reporting and disclosure project was implemented in 1999 and the results were presented in 2001 for the first time, disclosing results every year.
Emission rate (emission/dealings) is tended to gradually decrease since the beginning of the system. The volume of class one carcinogen contracts is increasing steadily while the emission is decreasing. A tendency to decreased emission is much more obvious.
The number of business site subject to information disclosure has been increasing gradually since 2008 and as from 2010, business sites should disclose the total emission of chemicals. Also the purpose of PRTR and business's efforts to reduce emission are continuously trained and promoted to avoid any unnecessary misunderstanding and exaggeration in emission results among related parties, including the public and businesses.
