The present invention relates to a system for cultivation of algae, extraction of lipids and transesterification of the lipids to obtain biodiesel. The toner container includes a pouch member that contains a new toner therein and can be turned inside out, and a cover member that covers an outside of the pouch member and includes an inlet through which a waste toner flows in, the inlet being formed opposite to a side of the cover member from which the new toner contained in the pouch member is discharged. A second data packet, which contains at least a part of the first data packet, is generated.
