Just days after test production began last week at Chinese company Semcorp’s separator film plant in Debrecen, the environmental authority has partially suspended operations at the factory, [...].

The news outlet contacted the government office, which provided the following statement:

“The environmental authority has immediately suspended test operations at seven point sources within Semcorp Hungary Ltd.’s Debrecen factory. The decision was made because emissions at 7 out of 16 point sources within the factory exceeded the limit values set in the integrated environmental permit.”

[...] Sources indicate that Semcorp considers the decision overly strict and has filed an appeal.

Semcorp manufactures separator films used in lithium-ion batteries. [...].

[...] it is already planning a second production unit with similar capacity in Debrecen, and is exploring the possibility of a third and fourth phase of expansion.
