Kad god razvrstate elektronski otpad, koristite odvojeno sakupljanje.

Kad god means whenever or every time that. It refers to something that happens repeatedly.

• kad = when
• kad god = whenever / any time that

So this sentence is giving a general rule or instruction, not talking about one single occasion.

Serbian has no articles, so there is no direct equivalent of the or a/an.

That means:

• elektronski otpad can mean electronic waste or the electronic waste, depending on context.
• odvojeno sakupljanje can mean separate collection or the separate collection system, depending on context.

English speakers often look for an article, but in Serbian the meaning is understood from the situation.

Razvrstate is the 2nd person plural (or formal singular) form of the verb razvrstati.

So it can mean:

• you all sort / classify
• you sort / classify when speaking politely to one person

In this sentence, it is used in a general whenever clause: whenever you sort electronic waste.

Razvrstati is a perfective verb, while razvrstavati is its imperfective partner.

Here, the perfective form razvrstate suggests the action as a completed sorting event each time it happens. The idea is roughly:

• whenever you sort it out / whenever you finish sorting it

If the sentence used razvrstavate, it would sound more like focusing on the ongoing or habitual process of sorting.

So:

• razvrstate = each completed instance of sorting
• razvrstavate = the activity/process of sorting

Here it is functioning as an imperative: use.

The form koristite can look the same as:

• 2nd person plural present = you use
• 2nd person plural / formal imperative = use

Context tells you which one it is. Since this sentence is clearly giving an instruction, koristite means use.

Both forms address either:

• more than one person, or
• one person formally/politely

In public notices, instructions, and official recommendations, Serbian often uses this plural/formal form. So the sentence sounds like a standard public instruction, similar to English notice-style language.

It is in the accusative case because it is the direct object of razvrstate.

However, for inanimate masculine nouns, the accusative looks the same as the nominative. So:

• nominative: elektronski otpad
• accusative: elektronski otpad

That is why there is no visible ending change here.

In Serbian, otpad is commonly used as a mass noun, much like waste in English.

So elektronski otpad means electronic waste in a general sense, not one piece of waste. Serbian does not need a plural noun here.

Literally, it means separate collection.

• odvojeno = separate / separated
• sakupljanje = collection / gathering

In context, it refers to using a separate collection system or separate waste stream for electronic waste.

No. Here odvojeno is an adjective, not an adverb.

It agrees with sakupljanje, which is a neuter singular noun:

• odvojeno sakupljanje = separate collection

It may look like an adverb because many Serbian adverbs also end in -o, but in this phrase it is adjectival and modifies the noun sakupljanje.

Serbian often uses the present tense in time clauses after words like kad, kada, and kad god, especially when talking about general rules or future-related situations.

So Serbian says, literally:

• Whenever you sort electronic waste, use separate collection

This is normal Serbian grammar. English actually does something similar in many cases: we also say When you arrive, call me, not When you will arrive, call me.

Yes. Serbian word order is fairly flexible.

For example, this would also work:

• Koristite odvojeno sakupljanje kad god razvrstate elektronski otpad.

The meaning stays basically the same. Putting the kad god clause first makes it sound a bit more like setting the condition first: Whenever this happens, do this.

The comma separates the introductory subordinate clause from the main clause:

• Kad god razvrstate elektronski otpad = subordinate clause
• koristite odvojeno sakupljanje = main clause

This punctuation is normal in Serbian when a dependent clause comes first.
