To repurpose something is to adjust the use of an item and extend its useful life
[verb]
To repurpose something is to adjust the use of an item and extend its useful life, instead of disposing of it. Repurposing something is to use it again by adapting, reprocessing, or regenerating it – and making use of it for a different function.
e.g. It is possible to repurpose glass bottles and jars giving them another life as vases and candle holders.
