In order to win the battle to defend the blue sky and regulate the pollution control of volatile organic compounds (VOCs) in the furniture manufacturing industry in Guangzhou, in accordance with the "Air Pollution Prevention and Control Law of the People's Republic of China" and other relevant regulations, the Guangzhou Municipal Bureau of Ecology and Environment Notice on the Remediation of VOCs Pollution (Draft for Solicitation of Comments)", which was printed and distributed on December 19, and is now open for comments.
The time for soliciting opinions is from December 19, 2019 to December 28, 2019 (10 days in total).
The notice is applicable to newly-built and existing furniture manufacturing enterprises in the administrative area of Guangzhou that have processes such as painting, spraying, sizing, and drying that generate volatile organic compounds.
The notice shall come into effect on the date of issuance and shall be valid for three years.
The remediation task requirements include: The remediation task requirements include: (1) Clean replacement of raw and auxiliary materials.
For wooden furniture manufacturing companies, it is required to use low-VOCs content coatings such as water-based, UV-curable coatings, and the replacement ratio reaches more than 60%; for metal furniture manufacturing companies, promote the use of itubang.

(3) Install high-efficiency pollution prevention and control facilities.
The installation of pollution prevention facilities by furniture companies should include: waste gas collection facilities, waste gas treatment facilities and waste gas exhaust pipes.
The exhaust pipes of exhaust gas collection facilities shall be equipped with closable sampling ports in accordance with the requirements of the "Guidelines for the Standardization of Pollutant Discharge Outlets of Guangdong Province" (Yuehuan [2008] No.
42) to detect the concentration of organic exhaust gas before and after purification, and there must be no bypass Or exhaust gas leakage.
Exhaust gas treatment facilities should have the functions of treating paint mist, filtering dust, and efficiently purifying organic waste gas, and can reflect the exhaust gas flow rate, total VOCs concentration and total VOCs removal rate (in line with relevant national and provincial standards) to ensure the stable emission of exhaust gas.
The height of the exhaust gas discharge tube is generally not less than 15 meters.
