Deadline is approaching, HBCD comprehensive elimination needs to be accelerated

Hexabromocyclododecane (HBCD), as a flame retardant with excellent performance, mature technology and low price, plays an important role in the industries of expandable polystyrene (EPS) and extruded polystyrene (XPS) insulation materials.

Hexabromocyclododecane (HBCD), as a flame retardant with excellent performance, mature technology and low price, plays an important role in the industries of expandable polystyrene (EPS) and extruded polystyrene (XPS) insulation materials.

Up to now, the total annual output of EPS and XPS insulation boards using HBCD as flame retardant in China has reached 1.

It's not easy to say goodbyeIt's not easy to say goodbye

Since the 1990s , HBCD has been widely used in thermal insulation materials, electronic equipment, polyester textiles, automobiles and other fields.

Since the 1990s , HBCD has been widely used in thermal insulation materials, electronic equipment, polyester textiles, automobiles and other fields.

In the 21st century, the characteristics of HBCD persistent organic pollutants have been confirmed by scientists.

However, eliminating HBCD is not easy.

According to the data provided by the China Plastics Processing Industry Association, China is the world’s largest producer and marketer of EPS and XPS .

At the press conference on HBCD performance work in the plastics industry and the exchange meeting on HBCD performance work held in Beijing on April 9th , Zhu Wenwei, chairman of the China Plastics Association, said that the elimination and replacement of HBCD is a systematic project.

Liu Jingjiang, director of the Agricultural Housing Construction and Green Building Materials Division of the Science and Technology and Industrialization Development Center of the Ministry of Housing and Urban-Rural Development, also said that how to balance green development and economic benefits is also a big challenge in the development, application and promotion of new alternatives.

The "successor" is hard at workThe "successor" is hard at work

To eliminate HBCD , the first step is to find a good " successor .

According to Qian Lijun, deputy secretary-general of the China Petroleum and Chemical Industry Federation’s Flame Retardant Materials Committee and a professor at Beijing Technology and Business University, during the 5- year exemption period, relevant scientific research units and manufacturers in China have carried out a large number of HBCD alternatives development.

"In order to meet downstream customers’ demand for new green alternatives, Japan Daiichi Pharmaceutical, Shandong Neptunus Chemical Co.

It is understood that Shandong Xurui New Material Co.

While flame retardant manufacturers are actively preparing for the war, downstream product processing companies are also intensively promoting the replacement of HBCD .

According to Zhang Benrong, technical engineer of Wuxi Xingda Foam New Material Co.
, Ltd.
, Xingda Foam started to develop new non- HBCD EPS flame retardant products as early as 2015.
At present, the new products can meet the requirements of flame retardant grade B2 or B1 .
, The mechanical properties of the product are comparable to HBCD flame retardant products.

Speaking of the economics of alternatives, Qian Lijun believes that although the current prices of the two alternatives are still higher than HBCD , in the future, with the increase in usage and mass production, their production costs will be reduced accordingly, and applications can be realized.
Simultaneous replacement of effects and production costs.

Choosing a good "successor" is only the first step in the elimination of HBCD .
After banning HBCD , how to deal with the aftermath of HBCD waste, ensure the harmless disposal and recycling, and assess and control environmental risks will become the focus of China's compliance work.

Ren Yong, deputy director of the POPs Convention Division of the Foreign Cooperation and Exchange Center of the Ministry of Ecology and Environment, said that after the end of the HBCD exemption period, the Ministry of Ecology and Environment will conduct regular enforcement supervision and inspection of HBCD production enterprises with the State Administration of Market Regulation in 2022 to ensure that enterprises perform their obligations.

He also noted that the next 20 ~ 50 years, China will have more than 1000 million tons with use of HBCD in the EPS , XPS insulation sheet will gradually expire, waste treatment, disposal and recycling of bromine and so there are a lot Work to be done.
For example, establishing national inventories and databases, developing best available technologies, and promoting best environmental practices to realize the recovery and recycling of bromine, EPS , and XPS .

Zhu Wenwei representation, of HBCD after a comprehensive alternative, the association will be of HBCD , the EPS beads, the EPS plate, XPS sheet of major manufacturers to conduct field research to understand the relevant circumstances, checks the EPS , XPS industry of sheet products for quality testing ; production enterprises and on the market HBCD and containing HBCD of the EPS , XPS waste and other research.
On this basis, the association will analyze the situation of HBCD- containing waste, organize industry experts to conduct waste recycling technology research, and organize forces to establish HBCD recycling bases ; cooperate with relevant departments to organize environmental safety assessment units to conduct HBCD production sites And the safety of the use environment is tested and evaluated.

Among them, the establishment of detection methods for HBCD in EPS and XPS insulation materials is the basis for environmental assessment and harmless disposal.
