The article presents analysis of the influence of selected methods alongside with devices applied to process oil waste from engine power room plants on the changes in oil waste morphology in order to improve burning conditions in auxiliary boilers. Study results facilitated the choice of the most favourable method, in view of environmental protection, of preparing oil waste to burn so that the waste is transformed into fuel for auxiliary boilers on the ship. Burning oil waste entails changes in its morphology, therefore, measurements of toxic emissions of CO and NOx have been conducted for each of the different processing methods.

The paper presents the results of anaerobic digestion and co-digestion under mesophilic conditions in the OxiTop system and in lab-scale fermentors. The goal of the study was to determine the effect of reaction-based oil waste on biogas production in co-fermentation with sewage sludge (mixture of thickened primary and excess sludge). The average water content in sewage sludge was 97 %, with 70 % of total volatile solids concentration (TVS) in total solids. Weight content of oil waste in the mixture of sewage sludge ranged from 15 to 45 % (w/w) and the increase in TVS to 83.7 % was observed. The primary investigations of gas productivity by manometric method (OxiTop) showed that biogas production increased with increasing content of oil waste in the mixture with sewage sludge. The rate constant of the first-order kinetics for biogas production was determined. To determine the yield parameters of co-fermentation, the experiment was performed in four continuously stirred anaerobic reactors with a working, volume of 10 dm3. Organic loading rate (OLR) changed from 0.9 to 3.1 kg TVS/m^3d. High correlation between biogas flow rate and OLR was observed. Volumetric biogas production rate and the average methane content in the biogas increased from 0.79 to 1.98 m3/m3-d and from 52.3 to 62.3 %, respectively, as OLR increased. The results obtained in lab-scale fermentors are promising and open the possibilities of the implementation of co-fermentation of sewage sludge and oil waste.

W artykule przedstawiony został obraz rynku tłuszczów odpadowych w Polsce. Dokonana została analiza jakościowa i ilościowa poszczególnych rodzajów tłuszczów w wybranych województwach. Dokonano szacunków produkcji i wielkości rynku tłuszczu odpadowego w całej Polsce. Przedstawione analizy dotyczą odpadowych tłuszczy zwierzęcych, posmażalniczych oraz porafinacyjnych kwasów tłuszczowych. Dane zostały zebrane na podstawie corocznych raportów składanych przez wytwórców odpadów. W artykule znalazła się również dyskusja i szereg uwag na temat wiarygodności systemu pozyskiwania danych tego typu w Polsce.

In the article waste fat market in Poland has been analyzed. Quality and quantity analyze has been made as well as evaluation of the total quantity of waste fat produced in Poland. Analyzed shown in the article include animal fat, waste fat remaining after frying processes and post-refining fatty acids. All data was obtained for reliable sources like annual reports of corporations producing waste fat. In the article several remarks about reliability of sources of information about waste management was made.
