GRI INDICATORS:
Capitals:

The main types of non-hazardous waste generated by the ORLEN Group included calcium-based reaction waste from flue-gas desulfurisation in solid form, slag and ash from wet removal of furnace waste, and sludge from industrial wastewater treatment processes. The main types of hazardous wastes generated by the Group included sludges from non-biological treatment of industrial wastewater, post-reaction and post-distillation residue containing halogen compounds, and spent catalysts containing dangerous transition metals or their compounds.

In total, ORLEN Group companies generated close to 213,000 Mg of non-municipal waste in 2017.

The table below presents the types of waste generated by ORLEN Group companies.

Quantity of waste generated at ORLEN Group companies in 2016 and 2017

Quantity of generated waste [Mg] 2017 2016 change [%]
Hazardous waste 100,128 75,267 33.03
Non-hazardous waste 112,863 97,779 15.43
Total 212,991 173,046 23.08

The increase in the amount of hazardous waste was due to a change in the methodology for estimating the weight of type 19 08 13* hydrated waste, which was previously reported as dry mass by ORLEN Lietuva. The increase also reflects a rise in oil throughput and fuel production rates.

19,370 Mg of generated waste was disposed of and 83,229 Mg was recycled in on-site facilities. 4,957 Mg of waste, including 2,919 Mg of hazardous waste and 2,038 Mg of non-hazardous waste, was transferred to on-site landfills. The remaining waste, along with waste in storage generated in previous years, was handed over to licensed operators.

Waste management

The most frequently used recovery methods were regeneration or re-refining and bioremediation of waste oils. Waste disposal takes place chiefly in incineration plants or wastewater treatment plants.

In 2017, 5,178 Mg of hazardous waste and 109,553 Mg of non-hazardous waste was sent for recycling abroad. 30,350 Mg of hazardous waste was transferred within the territory of the Group’s home countries.
