The aim of research - to investigate possibilities to decrease biodiesel fuel production cost price by using cheaper raw materials and introducing of integrated biofuel and biolubricant production system at the same enterprise. Investigation of properties of fatty acid methyl esters produced from fatty waste -animal fat (beef tallow and pork lard) and fibre linseed oil show that methyl esters produced from the above mentioned raw materials could not be used as biodiesel fuel in pure form. The properties of tri-component ester mixtures containing up to 30% of fatty acids produced from fatty waste (mixture of lard or tallow methyl esters with linseed oil methyl esters in proportion of 4:1) and rapeseed oil methyl esters meet the requirements of standard LST EN 14214 with antioxidants and depressants added. Concentration of harmful components in exhaust gases when engine is fuelled with the above mentioned mixtures is the same or slightly lower if compared with those of rapeseed oil methyl esters. Rapeseed oil and rapeseed oil methyl esters could be used as bases for biolubricant production. Their anti-wear properties are better if compared with the investigated commercial mineral oil. After modification of rapeseed oil and rapeseed oil methyl esters with additives the anti-wear properties are nearly the same as properties of semi-synthetic lubricants.
