Best practice
When using "which is produced", ensure the clause provides essential information about the noun it modifies. If the information is non-essential, consider using "that is produced" or restructuring the sentence for better flow.
Common error
A common error is using "which" instead of "that" in restrictive clauses. If the clause is essential to the meaning of the sentence, use "that"; use "which" only for non-essential, parenthetical information.

Ludwig's WRAP-UP
The phrase "which is produced" serves as a relative clause to provide extra, non-essential information about a noun. As Ludwig AI confirms, it's grammatically correct and commonly used, particularly in scientific, news, and encyclopedic contexts. It's important to distinguish its use from "that is produced", which introduces essential information. When writing, remember that "which is produced" adds descriptive details but isn't crucial for defining the subject. Alternatives like "that is manufactured" or "that is created" can offer stylistic variety.
