Waste management
In 2010, the total amount of waste from MOL Group operations (without INA and IES) was approximately 157 thousand tons, signalling an 18 percent increase compared to 2009. Due to our efforts the ratio of reused or recycled waste has increased by 15% since 2008.
Total weight of waste by type (t)
The increase in waste production resulted from several turnarounds and other maintenance works which had been postponed from the previous year. For example, the disposal of a large amount of oily sludge accumulated in the Danube Refinery’s waste water treatment plant led to 5,900 more tons reported in the Refining Division. The quantity of non-hazardous waste increased by 9000 tons due to an obligation to clean the designated area for the construction of the new CCGT Power Plant at the Danube Refinery.
Total weight of waste by disposal method (t)
Examples of waste management actions:
- Instituted waste reduction methods at the Rijeka Refinery in order to reduce the creation of oily sludge. Sludge was treated utilising the decanter and centrifuge technique (partial reuse);
- Treatment of 3000 tons of oil-based mud cuttings has been managed through bioremediation in Pakistan. Treated cuttings were later used in construction as fill material;
- Launched the Green Office Programme at several sites and countries. Measures included digitalization of documents, reduction of paper use (recycled paper use, 2-sided printing), installation of shared printers and refilling toner cartridges.
In our Lubricants Division, 19 % (2009: 9.2%) of sold products were recollected and used as raw material for bitumen production in our refineries.
Spills
In 2010, there were 15 spills into the environment (over 1 m3) by the MOL Group (excluding INA). Another 11 cases happened at our Croatian operations. The majority of spills happened at E&P due to ruptures on mainly oily water delivery pipelines. Some of the causes of the ruptures included the age of the pipelines, changed fluid composition at oil fields, and stealing of condensate from pipelines. In order to prevent further spills, E&P has invested great effort to replace or repair critical pipeline corridors.
Furthermore, due to pipeline sealing problems or other technological reasons, additional spills occurred at Refining and Marketing (10) and at Retail (2), resulting in another 186 m3 of contamination.
After detecting the incidents, all necessary measures for aleviating the damage and its consequences were immediately put into effect.
Remediation
MOL Group spent nearly 3 billion HUF for remediation of environmental damage in 2010. The share of responsibilty was divided among the Group as follows: MOL Plc. HUF 1.07 billion, Slovnaft HUF 1.45 billion, TVK HUF 0.12 billion and IES HUF 0.2 billion. Remediation actions were also necessary in other countries, including Bosnia, though the order of magnitude was lower.
Remediation tasks are managed at the group level, and are gradually being extended to the member companies. In INA, an assessment of provision-based environmental liabilities and the subsequent provisions (in line with the IFRS requirements) was completed in 2010. The primary goal of 2011 is the preparation of the future remediation programme and beginning the process of to eliminating environmental burdens.
The majority of our remediation and monitoring tasks are naturally in Hungary and Slovakia, with the number of related locations exceeding 250. Liabilities arise along the entire value chain. Besides the refineries, petrochemical and logistic sites, we also aim to improve the environmental status of various production facilities and filling stations. We have focused on monitoring activities, since in this way we can receive feedback regarding the success of remediation and risk minimisation actions. In 2010, we completed remediation at seven locations, and closed the post-monitoring phase at twenty further sites.
In 2010, with the support of the National Office of Research and Technology (NKTH), we continued our four-year (2009-2012) innovation programme in cooperation with TVK Plc. and external partners. The project titled ”Chemical Sector and Liveable Environment – Development of Innovative Technologies in the Protection of the Environment” supports the analysis and validation of sustainability criteria in remediation activities, as well as operating technologies with minimal power consumption and low waste or no-waste production (contaminated water, soil, filters, etc.). Successful tests of innovative barrier technologies were executed in the shallow and deep zones, which we aim to continue in 2011 as well.
