"How to say 'double usage' in English?"

"Double usage" can be translated into English as "double utilization" or "twice used". The term refers to an object, material, or resource that has been used twice, rather than once, for a specific purpose. This may occur due to various reasons such as cost-efficiency, environmental preservation, or optimization of production processes.

For example, a company might choose to use recycled materials for its products, reducing waste and costs while also promoting sustainability. Another example could be the use of renewable energy sources, which are utilized not only to generate electricity but also to heat buildings during winter months.

In terms of vocabulary, "double utilization" is a more formal and technical term that might be preferred in certain contexts such as business or engineering. "Twice used" is a simpler and more commonly used phrase that can be used in everyday conversation.

It's worth noting that "double usage" can also be applied to concepts beyond physical objects, such as skills or knowledge that have been put to different uses. For instance, a musician might write a song once and then perform it multiple times on different stages, using the same melody but varying the lyrics and instrumentation each time. In this case, "double usage" would refer to the way the musician has maximized the value of their creation through varied performance experiences.
