jednorazowo

Jednorazowo is a Polish adverb meaning “for a single use” or “one-time.” It is derived from the adjective jednorazowy (single-use, disposable) and is used to describe actions performed only once, or items intended to be used only once. In speech and writing, it can modify verbs or phrases, as in “Produkt został użyty jednorazowo” (The product was used once) or “Koszty poniesiono jednorazowo” (Costs were incurred at one time). The related noun form jednorazowość denotes the characteristic of being single-use.

In a broader sense, jednorazowo also appears in contexts referring to disposable products or packaging: “produkty jednorazowego użytku” (single-use products), “opakowania jednorazowe” (single-use packaging), or “sprzęt medyczny jednorazowego użytku” (single-use medical devices). The concept is central to discussions of waste, sustainability and policy, particularly regarding plastics and other disposable materials. Many regulations promote reusable alternatives and reduce single-use items, such as bans or charges on certain jednorazowe products.

Compared with similar terms, jednorazowo emphasizes the temporal aspect (one-time), while jednorazowy describes the object's nature (intended for one use).
