Various embodiments of the present disclosure provide techniques and systems for improving efficiency of fulfillment systems. One technique may include moving a plurality of container carriers to one or more carrier recirculation systems. The technique may include moving a plurality of item containers to a container recirculation system, positioned at least partially parallel to a carrier recirculation system of the one or more carrier recirculation systems. The technique may include moving, using a container partitioning assembly of the container recirculation system, an item container of the plurality of item containers into an induction system. The technique may include moving, using a carrier partitioning assembly of the one or more carrier recirculation systems, a container carrier of the plurality of container carriers to a loading position relative to the induction system. The technique may include loading the item container into an interior portion of the container carrier.

An apparatus for transferring and accumulating objects. The apparatus includes at least a first group and a second group of accumulation channels parallel to each other. Each accumulation channel having an elongated extension along a direction parallel to an accumulation direction between a loading end and an unloading end of objects. The accumulation channels of the first group having the loading ends aligned with each other and the accumulation channels of the second group having the loading ends aligned with each other. The apparatus further includes at least a first and a second transfer device for transferring objects to said accumulation channels. The first and second transfer devices receive objects in an alternating manner and the loading ends of the accumulation channels of the first group are misaligned with respect to the loading ends of the accumulation channels of the second group.
