    Production of biodiesel from food crops may cause negative economic, social, and environmental effects, therefore the alternatives are sought to satisfy the raw material demand for biodiesel production [1,2]. The aim of research is to evaluate the possibilities of application of non-food (Camelina sativa) ) oil, fatty wastes of animal origin and butanol for biodiesel production by applying biotechnological methods. The most effective biocatalyst suitable for the biodiesel synthesis from mixture of camelina oil and animal fat by transesterification with butanol was selected. The study involved six lipases as catalyst: Novozyme 435, Lipozyme TL IM, Lipozyme RM IM, F-EC, G “AMANO” 50. The synthesis of biodiesel was performed under the following conditions: temperature from 30 to 80oC; butanol-to-oil molar ratio from 1 to 7; enzyme content 3-17%; water content 0- 12%; duration 1-24 hours. Biodiesel properties were analysed according to the requirements of standards. Camelina oil is high in unsaturated fatty acids (more than 85 %) [3], iodine value of esters produced from camelina oil equals to 144 I2/100 g and exceeds the maximal value presented in the standard. In contrary, animal fatty waste is characterized by low iodine value (52 g I2/100 g) [4], the content of saturated fatty acids equals to 53 %. In order to meet the quality requirements presented in the standard, mixture camelina oil and animal fat in ratio 1:3 could be used for biodiesel production. For the investigations biocatalyst - lipase Lipozyme TL IM was selected. The optimal conditions for the production of biodiesel fuel were determined: 9 % of the lipase Lipozyme TL IM (of the weight of oil); molar ratio of oil and butanol – 1:6; temperature – 40 °C; duration – 6 hours in the first production stage. The optimal conditions of the second stage are as follows: lipase content – 5 %; molar ratio of oil and butanol – 1:8; temperature – 40 °C; duration of synthesis – 6 hours. It was determined that butylesters meet the standard requirements, when the additives of antioxidants Ionol BF 200 (1000 ppm) and depressant Chimec 6635 (2000 ppm) are used.
