With every oil tanker comes the risk of an accident and oil spill. Sorbents are the most suitable means to remove oil spills. Aerogels as sorbents have high porosity and can be made from cellulose from paper waste. The literature does not distinguish between paper and cardboard as sources of cellulose aerogels and little is known about composites of cellulose aerogels consisting of cellulose fibres and chemically untreated, unprocessed fibres or particles of straw, wool, macroalgae or cellulose acetate from cigarette butts. In this study, the sorption properties for marine diesel oil and biodiesel of such aerogels and their regenerative capacity with bioethanol were investigated. Cellulose aerogels were prepared from office paper and cardboard waste without and with chemically untreated algae, straw, wool and cellulose acetate as a composite by freeze drying. All samples were hydrophobised with methylsilane. The density to calculate the porosity and the contact angle were determined. Then the sorption capacity was determined over five cycles of sorption of oil and regeneration with bioethanol. The average contact angle of all samples was 125°, indicating hydrophobicity. Paper-based aerogels were found to consistently have higher sorption capacities for biodiesel, marine diesel oil and bioethanol than cardboard-based aerogels. In particular, the wool/cellulose aerogel composite was found to have better sorption capacity for biodiesel, marine diesel oil and bioethanol than all other samples. The cellulose acetate/cellulose aerogel composite showed significantly higher sorption capacities than the paper and cardboard control samples (highest value is 32.25 g g−1) only when first used as a sorbent for biodiesel, but with a rapid decrease in the following cycles.

Cigarette butts are the most known variety of anthropogenic litter on Earth, which consists mainly of cellulose acetate. It can be prepared as aerogel which can be used to remove oil pollution caused by heavy shipping traffic in the Baltic Sea. It is prepared as a solution in acetone which then is poured into water and oven-dried afterwards. The hydrophobicity can be simply improved by wetting with a little amount of oil. Aerogel’s sorption capacity, as well as its regeneration for sorption of crude oil, marine diesel oil, and biodiesel sorption from water surface, has been estimated. Their recyclability to fresh samples with re-characterization has been also determined. It has been found that multiple use of cellulose acetate aerogels is not effective because the sorption capacity decreases by up to 80% after a single use. However, the sorption capacity of recycled samples decreases by only 20% on average compared to the samples from the first batch. This capacity could be fully exploited during the life cycle of cellulose acetate.

Phthalate acid esters (PAEs) are widely used as raw materials for industries that are well known for their environmental contamination and toxicological effects as “endocrine disruptors”. The determining of PAE contamination was based on analysis of dimethyl phthalate (DMP), diethyl phthalate (DEP), dipropyl phthalate (DPP), dibutyl phthalate (DBP), diisobutyl phthalate (DiBP), dicyclohexyl phthalate (DCHP) and di(2-ethylhexyl) phthalate (DEHP) in wastewater and sediment samples collected from city sewer systems of Lithuania and Poland, and Denmark for comparison. The potential PAE sources as well as their concentrations in the wastewater were analyzed and discussed. The intention of the study was to determine the level and key sources of pollution by phthalates in some Eastern European countries and to reveal the successful managerial actions to minimize PAEs taken by Denmark. Water and sludge samples were collected in 2019–2020 and analyzed by gas chromatography-mass spectrometry. The highest contamination with phthalates in Lithuania can be attributed to DEHP: up to 63% of total PAEs in water samples and up to 94% of total PAEs in sludge samples, which are primarily used as additive compounds to plastics but do not react with them and are gradually released into the environment. However, in water samples in Poland, the highest concentration belonged to DMP—up to 210 μg/L, while the share of DEHP reached 15 μg/L. The concentrations of priority phthalate esters in the water samples reached up to 159 μg/L (DEHP) in Lithuania and up to 1.2 μg/L (DEHP) in Denmark. The biggest DEHP concentrations obtained in the sediment samples were 95 mg/kg in Lithuania and up to 6.6 mg/kg in Denmark. The dominant compounds of PAEs in water samples of Lithuania were DEHP > DEP > DiBP > DBP > DMP. DPP and DCHP concentrations were less than 0.05 μg/L. However, the distribution of PAEs in the water samples from Poland was as follows: DMP > DEHP > DEP > DBP, and DiBP, as well as DPP and DCHP, concentrations were less than 0.05 μg/L. Further studies are recommended for adequate monitoring of phthalates in wastewater and sludge in order to reduce or/and predict phthalates’ potential risk to hydrobiots and human health.

The ambitious new International Maritime Organization (IMO) strategy to reduce greenhouse gas emissions from ships will shape the future path towards the decarbonization of the fleet and will bring further ecological challenges. In order to replace the larger oil-based part of marine fuel with components from renewable sources, it is necessary to develop multi-component blends. In this work, biomethanol and biodiesel with two additives—dodecanol and 2-ethylhexyl nitrate—in 20 blends with marine diesel oil (MDO) were selected as alternative components to replace the pure marine diesel oil-based part of marine fuel. For this purpose, two base blends of diesel and biodiesel with and without additives were produced with biomethanol from 0 to 30% (volume basis). Of all the blends, the blends with 5% (volume basis) methanol had the best property profile in terms of density, kinematic viscosity, calorific value, cloud point, and cetane index according to the ISO 8217:2017 standard (DMB grade) in compliance with the IMO requirements for marine fuels. However, the flash point must be increased. The boiling behavior of the blends was also investigated. A cluster analysis was used to evaluate the similarity between the blends based on their different physical properties.

Oil pollution caused by heavy shipping traffic in the Baltic Sea could be removed by the help of highly porous aerogels made from the waste. These could be produced from environmentally friendly cellulose, e.g., from paper waste, but would have to be hydrophobized for oil sorption. Such a cellulose aerogel was investigated in this research work. Six types of aerogel with 0.5, 1.0, 1.5, 2.0, 2.5 and 3.0 wt% cellulose with porosities in the range of 96–98% stabilized by unsaturated polyester as cross-linker have been produced. Aerogel’s sorption capacity as well as its regeneration for sorption of crude oil, marine diesel oil, and biodiesel sorption from water surface and mechanical strength has been estimated. It was found out that crude oil sorption capacity reach 29.67 ± 0.39 g g−1, biodiesel—29.07 ± 0.26 g g−1, while marine diesel oil—26.26 ± 0.39 g g−1. The aerogel with 0.5 wt% cellulose shows the best sorption properties after 10 cycles of the sorption.

The contemporary progress in civilisation is combined with new scientific approaches, technological innovations and the huge and growing use of natural resources, which leads to their over-exploitation and, as a result, to their depletion. There is an opinion that without further regulation of economic growth and excessive harvesting of resources, the entire ecosystem of the Earth can be irreparably destroyed. The 2030 Agenda is based on the decoupling principle, which means that the economic growth of the manufacturing and service sectors must be faster than the consumption of natural resources and energy. To this end, countries around the world have developed and are still pursuing different environmental measures, such as regulations, laws and orders, taxes, etc. The most popular management systems in Europe are ISO 14001 and EMAS. The newest analyses reveal that a large number of companies that have received an EMAS certificate are not willing to renew their registration after some time and the reasons are not very clear yet. The article discusses the methods for environmental impact assessment, sustainable industry development and motivations for resources efficiency. The study of the selected three production companies operating in Lithuania and currently using a pollution prevention tool – the environmental management system – is presented and discussed aiming to evaluate the effectiveness of resources consumption.

In April 2018, the IMO adopted an ambitious GHG emissions reduction strategy for shipping. It will shape the future fleet decarbonisation pathway and helps to choose alternative fuels and technologies. Methanol as marine fuel leads to drastically reducing sulphur and PM compared to conventional marine fuel. Meanwhile, biodiesel, as sustainable energy source, is characterized by high cetane index, low toxicity, and good biodegradation. Methanol-biodiesel-diesel blends require only limited modification to engines and fuel systems. For this reason, methanol and biodiesel may be well suited partly substitute oil-based fuels in the existing ship fleet. In order to replace the larger portion of fossil compound in marine fuel by components from renewable sources, it is necessary to develop multi-component blends. However, an increase in the proportion of components in a blend could be critical for the final properties of the blend and requires detailed research. The physical-chemical properties of the methanol (up to 30 %), biodiesel (up to 10 %) and diesel components as well as their mixtures have been analysed. It has been found that considering to ISO 8217:2012 standard and environmental requirements a blend with 10 % methanol and 10 % biodiesel is the most suitable alternative for marine applications.

Regional sustainable development demands detailed structured efficiency counting methods overview, which allow to analyse industrial symbiosis effects. Currently industrial symbiosis is defined as mutual commercial and managerial co-habitat of business entities, which mainly in scientific literature are analysed in terms of legislative procedures and management rules. Regional sustainable development depends on Industrial symbiosis efficiency and synergy, which also can be counted by using methods of applied efficiency parameters. The article analyses the main efficiency counting parameters, used to evaluate industrial symbiosis in terms of regional sustainable development systems.

Recent emission related limits imposed on marine fuel are causing the ship owners to look for alternative fuels to comply with the new limits. Depletion of fossil fuel raised the attention of researchers to investigate renewable energy sources such as biodiesel and alcohol. Methanol blends as marine fuel leads to drastically reducing sulfur and particle emissions, adopting methanol also shows lower nitrogen oxide emissions and, when produced from renewable sources, lower CO2 emissions over the entire fuel lifecycle. Biodiesel has the potential in fulfilling the environment and economic concerns as it is a renewable and sustainable energy source. Empirical relationships among physical-chemical properties and blends of biomethanol-biodiesel-diesel were assessed by direct gradient analysis. It was inspected how the physical-chemical properties change along an ordination axis of detrended correspondence analysis using “vegan” package in R. Physical-chemical properties from the multivariate model were predicted by using two types of blends’ data. The first one was based on the simulated ranges from the used data in calibration of the redundancy analysis, whereas the second one consisted of simulated ranges extrapolated up to 99% of both blends. It was concluded that a blend with 10% biomethanol and 20% biodiesel was the most suitable alternative fuel for marine applications (considering to ISO 8217:2012 standard and environmental requirements for marine fuel).

The annual global oil market is about 40 million tons, including vegetable oil-based lubricants, and modified esters currently account for only about 10–15%. Half of these lubricants are getting into the atmosphere, water, and soil. That is why environmentally friendly lubricants present a rapidly expanding branch of industrial lubricants, which will become increasingly important over the next century. The aim of this work is to make a comparative analysis of fats. Animal fats and fish oil which are inappropriate for food industry were selected for the investigation purposes. The base and ferment hydrolysis were made in order to separate free fatty acids from selected fats. The produced esters, animal fats, and fish oil were studied by evaluation of their physicochemical properties. As a result, octyl esters which were produced from animal fats and fish oil are ascribed to 22, fish fats to 32, and animal fats to 46 classes.

This work aimed to evaluate the sorption capacity of natural sorbents (wool, moss, straw, peat) and their composites during the sorption of crude oil and of diesel overspread on the water surface. The work presents the research results of the maximum sorption capacity of the sorbents/their composites using crude oil/diesel; the sorption capacity of the sorbents/their composites when crude oil/diesel is spilled on the water surface; and the research results of the unrealized part of the crude oil/diesel in the sorbents. The results of the analysis showed that all the sorbents and their composites have their selectivity to crude oil less than 50%. Also the results showed that the distribution of diesel and water in the sorbents and their composites is very different compared with the distribution of crude oil during the sorption analyses. In total, the diesel in the liquid mass absorbed by the straw and the peat amounted to 17 and 20%, respectively. This shows that these sorbents are much more selective for water but not for diesel. A larger part of the diesel was in the liquid amount absorbed by the composites—up to 33%. Accordingly, the use of these composites in watery environments is much more effective than the use of individual sorbents. The composition of sorbents in the composite enhanced both the hydrophobic and the oleophilic properties; as a result, a more effective removal of the diesel and oil from the water surface was achieved.

One of the most popular transportation methods of crude oil is water transport, leading to potential spills of these pollutants in the seas and oceans and water areas of ports, during their extraction, transportation, transhipment and use. The growth of the Lithuanian economy and the expansion of competitiveness were hardly imagined without the development of the Klaipeda seaport. However, the intensity of shipping and the increase in cargo loading volumes at specialised terminals are associated with a higher risk of environmental pollution. To achieve a sustainable development of the seaport, it is necessary not only to ensure the prevention of potential water pollution but also, if necessary, to use environmentally friendly technology for pollution management. The work analyses the possibilities related to the collection of oil products from the water surface using natural sorbents (peat, wool, moss and straw) and their composites.The research of absorbed amount of crude oil and diesel fuel spilled on the water surface, while using sorbents and their composites, determined that sorbents' composite straw-peat (composition percentage of straw-peat 25-75 %) absorbs the major amount of both crude oil (60 % of the spilled volume) and diesel fuel (69 % of the spilled volume) comparing to single sorbents and sorbents' composite straw-peat (composition percentage of straw-peat 50-50 %).

The aim of the presented research was to assess the NOx emission and dispersion from marine ships in Klaipeda sea port. NOx emissions from ships operating in Klaipeda sea port were calculated using the Lloyd's Register detailed ship movement method, after collecting the information about technical characteristics of each marine ship visiting the port and the time spent staying in the port. After calculating the emission, the modelling using AERMOD software was completed and the dispersion of pollutants over different seasons of the year was determined. When performing the evaluation of NOx emissions it was estimated, that most of these pollutants enter the atmosphere from stationary vessels moored to quays with active auxiliary motors; this accounts even for up to 72% of the total NOx emission from marine ships in Klaipeda port. It was calculated that a total of 945.6 tons of NOx compounds enter the air basin from ships which operate in Klaipeda port. It was determined that the seasonality and meteorological conditions are a significant factor affecting the dispersion of pollutants. During winter time, a higher dispersion of pollutants is typically found at the source of contamination, and in the summer pollutants are decomposed more quickly and their concentrations as formed above the port are 30% lower, however, 40-50% higher concentrations are formed over the Klaipeda city residential districts.

Oil spills impose serious damage to the environment. A spilled crude oil or its products affect aquatic flora and fauna and influence the atmosphere as well. Such pollutants are especially dangerous for the water ecosystems, where biological self-purification processes are slower (for example the Baltic Sea), than in warmer regions. In this paper, we evaluate a sorption capacity of ecologically friendly natural sorbents, when the crude oil and diesel are spilled on the surface of water. The experiments are carried out in the laboratory, and the water from the Lithuanian Baltic Sea coastline and Curonian Lagoon is used. Moss, straw, wool, sawdust, and peat are the natural sorbents evaluated during the experiments. Chromatographic analysis of crude oil and diesel during the process of sorption was conducted as well. An experiment with some synthetic sorbents was carried out to compare the results with natural ones. The experiments showed that the most suitable material for crude oil or diesel fuel spilled on the water surface is peat. As well, Lagergren’s model was adopted to the case of the sorption processes we have investigated. It can be exploited as a decision support tool while deciding the required time interval to achieve maximum sorption capacity of the sorbent in use.

Many modern technologies for treatment of soil polluted with oil products are developed through creation of new and efficient bio-agents that help to degrade oil products. Another trend in development of new technologies aims to speed up the growth of soil microorganisms, this way accelerating biodegradation of oil products without the help of introduced microorganisms. The biodegradation of diesel fuel and heavy fuel oil was tested in the soil using chemical additives (oxidizing agents). The tests aimed to ascertain the impact of H2O2, KMnO4 and MnSO4 on residual concentrations of heavy fuel oil and diesel fuel, and the total number of microorganism colonies, as well as the number of oil-oxidizing microorganism colonies in the soil. After the statistical analysis of the data obtained during the experiment, a statistically significant (p

The present paper deals with an important environmental issue: air pollution with volatile organic compounds (VOCs) in oil terminals. In attempt to determine the dependence of VOCs concentration in the air on the wind speed and oil loading intensity analyses were carried out during shorter time intervals, when the fluctuations of ambient temperature are minimal (1−3) °C. VOCs concentrations were analysed by gas chromatography method in different chosen observation posts during different seasons. A complex analysis of experimental study and impact of meteorological conditions on the air pollution was performed taking into account the oil loading intensity in oil terminals and the types of loaded oil products. A new indicator was introduced for the analysis of the obtained results—a loading indicator that characterizes the amount and type of handled products as well as the number and type of operations carried out in the terminal. The dependence of the change of VOCs concentration on the loading indicator has been determined. Santrauka Analizuojama svarbi aplinkosauginė problema – oro tarša lakiaisiais organiniais junginiais (LOJ) naftos terminaluose. Siekiant nustatyti LOJ koncentracijos ore priklausomumą nuo vėjo greičio, aplinkos drėgmės ir atmosferos slėgio, atliktitrumpesnės trukmės tyrimai, kai aplinkos temperatūros svyravimai yra minimalūs – 13 ºC. Pasirinktuose stebėjimo postuose dujų chromatografijos būdu nustatytos LOJ koncentracijos skirtingais sezonais. Atlikta kompleksiniai eksperimentiniai tyrimai ir meteorologinių sąlygų (oro temperatūros, aplinkos drėgmės, atmosferos slėgio, vėjo greičio irkrypties) įtakos oro taršai analizė, atsižvelgiant į naftos terminalų krovos intensyvumą ir kraunamų produktų rūšis. Analizuojant gautus duomenis įvestas naujas rodiklis – krovos indikatorius, apibūdinantis kraunamų produktų kiekį, rūšį, terminale atliekamų operacijų skaičių ir pobūdį. Nustatytas LOJ koncentracijos kitimo priklausomumas nuo krovos indikatoriaus. Statistiškai apdorojus rezultatus akivaizdu, kad naftos terminaluose krovos operacijų skaičius ir pobūdis(krovos indikatorius) lemia LOJ koncentraciją pažemės atmosferos sluoksnyje. Atlikus LOJ koncentracijos tyrimo skirtingais sezonais duomenų analizę ir daugiafaktorinę dispersinę analizę, 95 % patikimumu nustatyta, kad LOJ koncentracijos kitimas pažemės atmosferos sluoksnyje priklauso nuo vėjo greičio, kai vėjo stiprumas yra didesnis nei 4 m/s (10 m aukštyje, P < 0,05). Резюме Исследована проблема испарения легколетучих органических соединений (ЛОС) на нефтебазе. Для того, чтобыустановить зависимость концентрации ЛОС от скорости ветра, влажности воздуха и давления атмосферы былопроизведено исследование концентрации ЛОС в воздухе, во время которого изменение температуры непревышало 3 градусов. Методом газовой хроматографии были исследованы сезонные выбросы ЛОС в приземныеслои атмосферы. Комплексно проанализированы полученные экспериментальные данные и метеорологическиеусловия (температура и влажность воздуха, давление атмосферы, сила и направление ветра) с учетомпроизводимых операций по перегрузке нефтепродуктов и их типа. Для более точного анализа полученных данныхбыл сформулирован новый «индикатор погрузки», который характеризует количество и тип перегружаемыхнефтепродуктов, количество и тип производимых технологических операций. В связи с этим была установленазависимость концентрации ЛОС от индикатора погрузки. Статистический анализ данных показал, что количествопроизводимых технологических операций на нефтебазах, а также их тип, влияют на изменение концентрацииЛОС. Анализ исследования сезонных выбросов ЛОС и многофакторный дисперсионный анализ данных с 95%й точностью показали, что изменение концентрации ЛОС в приземных слоях атмосферы зависит от скорости ветрав том случае, если она превышает 4 м/с на высоте 10 м (P < 0.05).
