Abstract: The invention provides a system for rearing insects, including at least one room for storing a plurality of crates for storing insects to be reared, a dosing station for filling insects and/or feed to the crates, an automated central harvesting unit including a harvesting station for unloading the insects from the crates for subsequent processing of the insects and/or a plurality of further processing stations, a crate collection system for transferring the crates between the at least one room and the central harvesting unit comprising a plurality of crate collection devices for collecting crates in or from the at least one room, and a connection for connecting the at least one room and the central harvesting unit.

Abstract: A support element for storing crates, wherein the support element is an elongate element having a cross section that is substantially formed in an U-shape, comprising a bottom section and two opposite side walls extending from the bottom section. The side walls each comprise a top portion, forming two elongate supporting areas, whereby the elongate supporting areas are configured to support a crate or a column of stacked crates, The inner side sections of the side walls each comprise a step symmetrically protruding to the inside of the U-shape forming two elongate running surfaces, whereby the elongate running surfaces are configured to support a conveyor system for transporting the crate. The invention further refers to a support system, a storage system and to a rearing unit.

Abstract: The invention relates to a biomass composition comprising insect particles or worm particles. The insect particles are for example derived from larvae such as fly larvae, in particular larvae of the species black soldier fly. The insect particles are for example provided by grinding insects. The biomass composition comprises for example ground grain and/or tuber parts of a root vegetable. The invention also related to a method for providing a biomass composition comprising insect particles or worm particles. In addition, the invention relates to the use of the biomass composition in the production of fertilizer, biofuel, animal feed. Furthermore, the invention relates to such fertilizer, biofuel, feed, comprising the biomass composition.
