Definition
废旧 is an attributive adjective (定语形容词) meaning 'old and discarded' or 'obsolete'. Unlike regular adjectives, it can only be placed directly before a noun to modify it — you cannot use it as a predicate (e.g., you cannot say *这个东西废旧). Instead, you must say 这个东西是废旧的 or use a different structure. Common collocations include 废旧物品 (waste items), 废旧电池 (used batteries), and 废旧材料 (scrap materials).
attr.
(attributive) old and uselessdiscardedscrap
