Volatile organic compounds, commonly referred to as VOC, are the abbreviations of the first letters of the three words Volatile Organic Compound. In 2019, the state updated the VOC organic waste gas treatment standards for the electronics industry. Electronic companies should learn the latest new standards for VOC waste gas emissions in a timely manner to prepare for the new environmental impact assessment requirements in 2019. Shenzhen ESKY cleanrooms Technology Co., Ltd. summarizes the new industrial VOC treatment standards for your reference.

 

National level:

In 2008, the Ministry of Environmental Protection issued the "Electronic Industry Pollutant Emission Standards for Semiconductor Devices" (Draft for Comments). The limit value of VOCs is 100mg/m3 for existing enterprises and 80mg/m3 for new enterprises.

In 2008, the Ministry of Environmental Protection issued the "Electronic Industry Pollutant Emission Standards for Electronic Components" (Draft for Comments). The limit of VOCs is 80mg/m3 for existing enterprises and 50mg/m3 for new enterprises.

In 2008, the Ministry of Environmental Protection issued the "Electronic Industry Pollutant Emission Standards for Electronic Terminal Products" (Draft for Comments). The limit of VOCs is 70mg/m3 for existing enterprises and 50mg/m3 for new enterprises.

In 2008, the Ministry of Environmental Protection issued the "Electronic Industry Pollutant Emission Standards for Flat Panel Displays, Vacuum and Optoelectronic Devices" (Draft for Comments). The limit of VOCs is 100mg/m3 for existing enterprises and 80mg/m3 for new enterprises.

In 2015, the Ministry of Environmental Protection issued the "Electronic Industry Pollutant Emission Standard" (draft for comments), which stipulates that the maximum allowable emission concentration of non-methane total hydrocarbons is 100mg/m3, and the special emission limit is 80mg/m3, and TVOCs are not involved.

In 2018, the Ministry of Environmental Protection issued the "Electronic Industry Pollutant Emission Standard" (second draft for comments), which stipulates that the maximum allowable emission concentration of non-methane total hydrocarbons is 100mg/m3, and TVOCs is 150mg/m3. The special emission limits are 50 and 100 respectively.

Local level:

Beijing's "Comprehensive Emission Standards for Air Pollutants" (DB11/501-2007) stipulates that the VOCs limit for semiconductor and electronic product manufacturing is 50mg/m3 for existing enterprises and 20mg/m3 for new enterprises.

Tianjin's "Volatile Organic Compound Emission Control Standards for Industrial Enterprises" (DB12/524-2014). The maximum allowable VOCs emission concentration for the electronics industry is 80mg/m3.

Shanghai's "Semiconductor Industry Pollutant Emission Standards" (DB31/374-2006). The maximum allowable VOCs emission concentration is 100mg/m3.

Guangdong Province's "Emission Standards for Volatile Organic Compounds in Electronic Industry" (Draft for Comments) in 2017. The maximum allowable emission concentration of VOCs is 30mg/m3.

Guangdong Province's "Emission Standards for Volatile Organic Compounds in Electronic Equipment Manufacturing Industry" (Draft for Comments) in 2017. The maximum allowable emission concentration of VOCs is 40mg/m3.

Jiangsu Province's "Semiconductor Industry Pollutant Emission Standards" (Draft for Comments) in 2018. The maximum allowable emission concentration of non-methane total hydrocarbons is 60mg/m3.

Beijing's "Emission Standards for Air Pollutants in Electronic Industry" (Draft for Comments) in 2018. The maximum permissible emission concentration of non-methane hydrocarbons is 20mg/m3, and TVOCs is 40mg/m3.

Industrial VOC waste gas treatment has entered the secondary stage, and the VOC emission standards for the electronics industry are in the new national standard and local standards. The formulation of local emission policies is a reasonable adjustment on the national standard. The VOC emission standards for Suzhou electronic enterprises stipulate that the maximum permissible emission concentration of non-methane hydrocarbons is 60mg/m3. Enterprises should adjust the latest emission requirements in a timely manner to avoid the consequences of non-compliance with environmental impact assessment standards.
