The heat values of waste mineral oils are equal to the heat value of the fuel oil. However, heat value alone is not sufficient for the use of waste mineral oils. as fuel. However, the critical physical properties of fuels such as density and viscosity need to be adapted to the system in order to be used. In this study, the engine oils used in the first 10,000 km of the vehicles were used as waste mineral oil. An organic-based Mn additive was synthesized to improve the properties of the waste mineral oil. It was observed that mixing the Mn additive with the waste mineral oil at different doses (4, 8, 12 and 16 ppm) improves the viscosity of the waste oil and the flash point. The resulting fuel was evaluated for emission using different loads in a 5 kW capacity generator to compare the fuel with standard diesel fuel and to determine the effect of Mn addition. In the experimental study, it was observed that the emission characteristics of the fuel obtained from waste mineral oil were worse than diesel fuel, but some improvement with Mn addition. As a result, we found that the use of waste mineral oils in engines in fuel standards was not appropriate, but may be improved with additives.

About 80% of the total pollution from ships is caused by operational oil discharges into the sea, often made deliberately and in violation of international rules; the main reasons can be due to cost savings or lack of adequate facilities in ports to receive waste oils. Therefore, reducing waste oil discharges is crucial for a proper protection of the marine environment. In this regard, the paper presents the preliminary feasibility of a particular waste recycling technology, aimed at obtaining marine fuel oil from sludge, through a pyrolysis process to be carried out in a small reactor onboard. The originality of the research consists in the adaptation of pyrolysis to oily waste produced by ships, since this technology is traditionally applied to solid waste and biomass. Furthermore, the plant has to be designed for operation on board the ship, therefore under very different constraints compared to traditional land plants. Although the preliminary lab tests and simulation results in the chemical process are promising enough, there are still some technical criticalities due to the energy optimization of the reactor for an efficient use onboard of the whole system. In addition, the possibility of recycling waste, directly onboard ships, is not yet covered by mandatory regulations, which is why shipowners generally still feel unmotivated to invest in such technologies.

ABSTRACT In June of 2000, U. S. Coast Guard Marine Safety Office (MSO) San Juan conducted the Annual Abandoned Vessel Inventory and noticed an abandoned vessel grounded on a beach in Fajardo, Puerto Rico. Personal investigation revealed that the vessel held approximately 5,000 gallons of waste oil in the engine room, posing a pollution threat to the local public. In a thorough attempt to identify the owner, the MSO used the knowledge of local fishermen, the marine police and Department of Natural Resource. When the owner could not be identified, the Captain of the Port decided to use the Oil Spill Liability Trust Fund to remove the threat of an oil discharge. Upon discovering that five marine batteries and filters had been hidden on board the vessel, it was determined that it was likely being used as a waste dumpsite. If it was indeed a dumpsite, the Coast Guard would then take control of the vessel, initiate salvage operations, and remove it from its location. Local contractors were hired in the first successful oil removal attempt, lasting two days. In April of 2001, the re-assessment was conducted and an additional 5,000 gallons of waste oil was again discovered on the vessel, confirming the belief that it was a dumpsite. A more in depth assessment was conducted, and another 10,000 gallons of fuel oil was discovered in the wing tanks. The second project commenced with a local environmental contractor hired to remove the 15,000 gallons of oil. Then a salvage contractor was hired to mechanically cut the vessel into scrap for disposal. During this time over 300 lbs. of commercial grade C-4 explosives and detonation cord were discovered in a hidden compartment in the aft end of the vessel. The total cost to the Oil Spill Liability Trust Fund was approximately $700,000.00 and over 2,000 man-hours were spent to complete the project. This three month long abandoned vessel removal is considered an important success for several reasons. Not only did the Coast Guard remove a major pollution threat from the environment, but the municipality has also renovated the beachfront area and installed a boardwalk for public access.

Vessels of the shipping industry produce sludge during the operation of the main engine, various types of auxiliary engines, and the handling of fuel oil on board ships. The sludge can be stored in special tanks and disposed of ashore or burned on board. In the European Union, according to the Port Reception Facilities Directive (EU) 2019/883, ships have to pay a port waste fee for the delivery of ship waste, which is calculated according to the size of the ship. Such an approach does not take into account the capacity of port green waste logistics. In this paper, the case of delivery of ship sludge to ports that are similar in terms of waste logistics capacity is analysed. It is presented as a mathematical game between ships and ports to improve green waste logistics and match the amount of oil sludge that can be discharged from ships to the capacity of ports. The goal of the game is to discourage free-riders, which can occur on both sides, between suppliers and ports. The waste rate can be used as a regulator and incentive that discourages sludge dumping when recycling is not feasible. A model evaluation is proposed using a numerical example.


One of the most promising ways of recycling waste oil and oil refining industries, in particular oil sludge, is their processing into valuable building and road materials. Solving this issue can help reduce the negative impact on the environment, rational use of natural resources and improve the state's economy. In this regard, it is important to conduct research on the physical and chemical properties and thermal characteristics of oil sludge samples taken under the conditions of Pavlodar Petrochemical Plant LLP, which was the purpose of this work.

Non-standard wastes — those defined as being both hazardous waste under the United Kingdom Hazardous Waste Regulations 2005 [1] and radioactive under the Radioactive Substances Act 1993 [2] — pose particular, unique challenges for radioactive waste management organizations [3]. Treatment and disposal routes for such wastes are limited, in some cases non existent, and generally not cost effective. A non-standard waste of particular concern in the United Kingdom, and indeed on the Sellafield site, is that of radiologically contaminated waste oil. The optioning process for treatment of bulk contaminated waste oil on the Sellafield site has assessed a range of options including incineration, chemical decontamination, physical decontamination and immobilization. Immobilization has proved to be a potentially useful option for oil wastestreams that fail to meet waste acceptance criteria for incineration facilities. Experimental development work has been undertaken at Sellafield during 2006 to test the suitability of an innovative technology for the solidification of waste oil with a cross section of wastestreams from the site. These trials have demonstrated that this polymer system is able to successfully immobilize a range of aged, chemically and physically diverse contaminated oil wastestreams and thus provide a potential solution to the disposal problem posed by this wastestream.

The biotreatment of an industrial waste oil condensate has been investigated. The waste is an oily emulsion resulting from chemical processing and condensation of grease trap wastes and industrial waste oils. The oil consists of a complex mix of hydrocarbons with significant fuel oil and lube oil fractions. Currently this waste is disposed of by incineration. The feasibility of using a biological pretreatment process to remove a significant proportion of the hydrocarbons has been investigated. Enrichment cultures produced a stable bacterial consortium. Flask cultures of this enrichment culture were capable of rapid emulsification of the oil. Within 10 days, 40–50% of the oil waste was degraded. Degradation was monitored using gas chromatographic analysis with flame ionisation detector (GC-FID) and by assessment of microbial dehydrogenase activity using triphenyl tetrazolium chloride (TTC) dye reduction. The enrichment culture consisted of 9 component organisms, 7 Gram negative and one Gram positive organisms. Their degradative abilities in monoculture have been investigated. Degradation of the waste using monocultures was monitored using GC-FID analysis of the Pristane:C17 ratio in the waste. The degradation capability of each of the component organisms in pure culture was similar to that of the consortium.
