Different types of tools and techniques mechanization fueled biometan ( pure biogas ) which is and will continue to be developed , among others, the fields of mechanical engineering agriculture ( tractors , water pumps / irrigation , pond aeration windmills biogas ) , agricultural process engineering / food ( powerl thresher of corn , beans and rice Mill Unit biogas ) , workshops and agricultural electricity ( electric generators , welding generators and handlebar , biogas burner ) , organic composting tools ( cutting machines , composter and machinery sieving biogas ) .
Basically , every agricultural machinery and engineering tools – which requires the engine – with the presence of certain biogas engine can be changed from the use of fuel oil ( BBM ) into fuel biometan ( pure biogas ) .
