February 23 (SeeNews) - Croatian fertiliser producer Petrokemija Group [ZSE:PTKM-R-A] said on Wednesday it swung to a consolidated net loss of 9 million kuna ($1.4 million/1.2 million euro) last year, from a 267 million kuna net profit in 2020, due to rising prices of natural gas and CO2 emissions, shrinking demand and an overhaul of production capacities.
