ENVIRONMENT
Through our decarbonization strategy we are establishing our technology outlook on the transition to lower carbon and renewable energy and the future projects for implementation.
The first directions set forward aimed at reducing CO2 emissions involve:
- CO2 recovery from the current Hydrogen Production Plant, 120 kt/year capacity
- Renewable energy generation - 100 MW solar PV and 100 MW wind
- Co-processing of vegetable oils to produce HVO
- Building a new bioethanol plant
Rompetrol Rafinare owns and operates the Petromidia Refinery, in Năvodari, Constanța, with a petrochemical plant, and the Vega Refinery located in Ploiești, Prahova.

Energy
Within the Refining BU we monitor on a daily basis several energy efficiency indicators. These indicators are influenced by the increasing complexity of the refining units following the extensive development initiatives, the subsequent higher throughput, along with energy efficiency measures (low cost/no cost) & dedicated projects aimed at reducing energy consumption while optimizing operations.

BU Refining Energy is a compressive indicator which shows the integrated energy performance of Petromidia Refinery and the Petrochemical Unit, along with Vega Refinery. BU Refining Energy = (Petromidia + Vega + Petrochemical energy consumption) / (Petromidia + Vega + Petrochemical total throughput) Energy Intensity Index (EII) for Petromidia Refinery shows how efficiently it utilizes energy and is equal with Actual Energy Consumption in GJ/day divided by Standard Energy in GJ/day multiplied by 100. Actual Energy Consumption (GJ/day) = ∑ (steam consumption, steam production, fuel gas consumption, power consumption, coke on catalyst & flue gases from FH2, for Units and Off sites area) Standard Energy (GJ/day) = standard energy for all units (unit capacity * utilization * EII factor) + Off sites & Utilities energy The EII factor may either be a constant factor or a result of several variables describing the unit’s feedstock and operating conditions, while Off sites & Utilities energy is a linear function of daily net throughput and complexity. Petromidia Refinery Energy Index is the ratio between Total Energy Consumption and Refinery Total throughput. Energy Index for Polymers (EIP) shows how efficiently the Petrochemicals Plant utilizes energy and is equal with Actual Energy Consumption in GJ/day divided by total yield (polymer & polymer‑grade propylene) Vega Refinery Energy Index is the ratio between Total Energy Consumption and Refinery net Input. |

Water
Rompetrol Rafinare has dedicated internal procedures in place, which document water management, covering quality monitoring, verification and maintenance of wastewater transport facilities, sealing and isolation of structures/basins, monitoring of technological processes, checking the quality of process water from intake to discharge.
Water management is performed in compliance with the requirements of Water Permits, issued every 3 years.
All specific pollutants (mentioned in the permits) are monitored in the discharged water, with different frequencies (daily, weekly, monthly, quarterly). Water analyses are performed by ISO-17025 accredited laboratory.
In 2022 there was no exceeding of the concentration value limits for pollutants discharged.
In 2022, the water recirculation coefficient was 97% for cooling water.
BIODIVERSITY
Our biodiversity policy recognizes the crucial importance of biodiversity resources worldwide, as well as our company's direct and indirect impact on these resources and our dependence on them.
For each new project, prior to implementation, we conduct an environmental impact assessment which identifies, describes, and evaluates the significant direct and indirect effects of the following factors: 1. population and human health; 2. biodiversity, paying special attention to protected species; 3. land, soil, water, air and climate; 4. material assets, cultural heritage and landscape.
Rompetrol Rafinare – Petromidia (Năvodari) is located near Natura 2000 Sites, the Tașaul Corbu Lakes and the Black Sea. Also, the last stage of the Wastewater Treatment Plant is located on the territory of the Danube Delta Biosphere Reserve.
EMISSIONS
Our new projects capable of reducing GHG emissions (high cost/high impact on CO2 reduction):
- Increase share of biofuels in regular diesel components - Coprocessing of vegetable oils in 122-Diesel Hydrotreater (DHT). Unit revamp is required to process spent or fresh vegetable oils for producing Hydrotreated Vegetable Oils - HVO (technical study required for unit revamp)
- Partial replacement of conventional biofuels with second generation biofuel (study required for feed availability) - New Bioethanol Plant, 50 kt/year capacity, second generation biofuel
- Carbon Capture and Storage (CCS)/Carbon Capture and Usage (CCU) – included in Decarbonization Strategy | feasibility study with Roland Berger completed| output under analysis to define strategy
- Install new heater in the VD unit at Vega Refinery.
Petromidia Refinery
The primary source of CO2 emissions falls under SCOPE 1, which includes emissions generated by both stationary and mobile equipment. As for SCOPE 3, the primary source of emissions is the combustion of products produced and sold by the refinery, such as gasoline, diesel, and jet fuel.
It is worth noting that the refinery has implemented measures to minimize CO2 emissions. There is no venting process, and CO2 fugitive emissions are absent. Rather than measuring CO2 emissions at the stack, the refinery calculates the emissions based on activity data, such as fuel consumption and unit throughput.
The contribution of flaring to total GHG emissions (direct) in 2022 was 0.21 % (1,817 to CO2 from a total of 881,633 to CO2 – direct emission of refinery and petrochemical units: combustion of fuels in furnaces, boilers and process emissions). For comparative purposes the same indicator had a value of 1.07% in 2021 (7,514 to CO2 from a total of 702,940 to CO2), and 0.97% (7,915 to CO2 from a total of 812,031 to CO2) in 2020, while in 2019 it was 0.7% (6,786 to CO2 from a total of 992,859 to CO2).
Biogenic CO2, from the breakdown or combustion of biomass, is part of a natural cycle where it's absorbed by biomass and then released back into the environment. KMGI includes biofuel in its products, applying GHG Protocol guidance to account for its lifecycle emissions, which assumes net zero impact.

** Scope 2 emissions, which are related to the purchased steam, were calculated for the years 2019 through 2021. During this period, the steam producer, UT Midia, was not part of our group and was only acquired in November 2021. As of 2022, with Rompetrol Energy now part of the Group, we have established boundaries to prevent double reporting at the KMGI level.

In terms of air quality assessment, Petromidia Refinery relies on the Aria soft provided by Aria Technologies to monitor and predict the dispersion of pollutants in the vicinity of the Petromidia platform, in compliance with Romanian and European Union regulations. The ARIA application models the dispersion of pollutants such as SO2, NOx, CO, PM, VOC, and H2S during normal oper-ations by gathering online data from the activities con¬ducted on the Petromidia platform. To ensure accurate modelling of pollutant dispersion into atmosphere, meteorological data from the local weather station is also considered.

To monitor air quality indicators such as H2S, VOC, BENZEN, SO2, PM 10, and meteorological conditions, two air quality monitoring stations have been installed in the Vega Refinery area in accordance with the requirements of Law no. 104/2011 (which transposing Directive 2008/50/EU on ambient air quality and cleaner air for Europe). The reports generated by these stations are sent daily to the competent authorities for environmental protection local authorities. The aim is to detect any potential breaches of atmospheric limit values.

WASTE
Petromidia Refinery - The waste generated by the company is managed in accordance with the legal provisions on waste management, embedded in internal procedures and instructions.
92% of the total waste that left the Petromidia platform in 2022 was sent for recovery.
Vega Refinery has contracts with authorized companies for the collection, transport and recovery/disposal of waste generated by the activities carried out on the entire site.
Historical Waste (not resulting from normal production) from Vega Refinery landfill (14 lagoons) is located on the northern side of the refinery platform and covers an area of approximately 82,450 m2. The lagoons have waterproof layers of compacted soil and bentonite.
There is an ongoing project to clean the lagoons; the existing waste is treated and stored in waterproofed cells according to GED 757/2004. The total quantity treated and stored by the end of 2022 is 89,039.48 tons.
In 2022, no spills recorded by either Petromidia or Vega refineries.
