A Bud Sorter white plastic bin is a specialized, typically food-grade, receptacle used in the post-harvest processing of cannabis flowers. It is designed to work as a component of a manual or automated sorting system, where trimmed cannabis buds are placed.

The bin's primary function is to temporarily hold and segregate buds that have been sorted by size, quality, or strain. The white color is often preferred in cannabis and horticulture environments because it is non-pigmented, easy to clean, and provides a clear, high-contrast background, which helps processors visually inspect and grade the product for consistency and contaminants.

In essence, it is the clean, hygienic container that receives the final, sorted cannabis flowers before they proceed to curing or packaging.
