Here, 에 marks the location where something was placed.

So:

• 집결지 = gathering point / assembly area
• 집결지에 = at / in the gathering point

With verbs like 놓다 (to place, put down), 에 is commonly used for the destination or location of placement.

Compare:

• 책상에 책을 놓았습니다. = I put the book on the desk
• 방에 가방을 놓았습니다. = I put the bag in the room

So 집결지에 tells you where the sacks and trash tongs were put.

집결지 means a place where people gather or assemble.

It is made up of:

• 집결 = gathering, assembling
• 지 = place/site

So it often means:

• assembly point
• meeting point
• gathering area

It sounds a bit formal or situational, and you might see it in contexts like:

• volunteer cleanups
• organized events
• emergency instructions
• military or group movement contexts

In everyday casual speech, people might sometimes use more common alternatives depending on context, but 집결지 is perfectly natural in notices or organized activities.

마대 usually refers to a large sack or bag, often a rough work bag used for carrying things like trash, recyclables, grain, or construction materials.

In this kind of sentence, it likely means something like:

• collection sack
• large trash sack
• work sack

It is not the most basic beginner word, so it is normal if it feels unfamiliar. In cleanup contexts, 마대 often means the big bags provided for collecting litter.

Because the two nouns are being linked together as one combined object of the verb.

Structure:

• 마대와 쓰레기 집게를
• the sacks and trash tongs
  • object marker

In Korean, when two nouns are joined with 와/과, the object particle is often attached only to the final noun phrase.

So this is natural:

• 사과와 바나나를 샀어요. = I bought apples and bananas.

Not:

• 사과를 바나나를 샀어요. ✘

You can think of 마대와 쓰레기 집게 as one grouped object, and 를 marks that whole group.

와 and 과 both mean and for nouns.

Which one you use depends on the sound of the noun before it:

• after a vowel: 와
• after a consonant: 과

Since 마대 ends in a vowel sound, it becomes 마대와.

Compare:

• 사과와 배
• 책과 공책

하고 can also mean and, but it is generally more conversational.
In a sentence like this, which sounds like a notice or report, 와/과 fits well.

It is written as two words here:

• 쓰레기 = trash
• 집게 = tongs, pincers, grabber

So 쓰레기 집게 literally means trash tongs or litter pickers.

This is a noun + noun combination, which is very common in Korean. The first noun describes the second:

• 커피 잔 = coffee cup
• 휴지 통 = trash can
• 쓰레기 집게 = trash tongs

In real-life translation, you might say:

• litter pickers
• trash grabbers
• trash tongs

depending on the exact tool.

놓았습니다 is the formal polite past form of 놓다.

Breakdown:

• 놓다 = to put down, place, set down, leave in a position
• 놓았습니다 = placed / put / set down

It sounds formal and complete, like something you might see in:

• announcements
• written notices
• reports
• official communication

So this is not casual speech. It has a polite, informative tone.

Both can sometimes be translated as put or left, but the nuance can differ.

• 놓았습니다 focuses on placing something somewhere.
• 두었습니다 often suggests put and left there or kept there.

So in this sentence:

• 놓았습니다 = the items were placed there
• 두었습니다 = the items were placed there and left available there

In many contexts, either could work, but 놓았습니다 is a straightforward, neutral choice for saying the items were set out at the gathering point.

It is omitted, which is very common in Korean.

The sentence does not explicitly say who placed the items. Depending on context, it could mean:

• we placed
• someone placed
• they placed
• the organizers placed

Korean often leaves out the subject when it is obvious from the situation.

So instead of saying:

• 우리가 집결지에 마대와 쓰레기 집게를 놓았습니다.

it is very natural to just say:

• 집결지에 마대와 쓰레기 집게를 놓았습니다.

This is especially common in notices and practical instructions.

Because Korean word order is flexible, and speakers often put location or time information early in the sentence.

This sentence goes:

• 집결지에 = at the gathering point
• 마대와 쓰레기 집게를 = sacks and trash tongs
• 놓았습니다 = placed

This is a very natural order in Korean. It helps set the scene first, then say what was placed there.

You could think of it as:

• At the gathering point, [we] placed sacks and trash tongs.

That kind of ordering is extremely common in Korean.

Yes. 놓았습니다 uses the -습니다 style, which is formal and polite.

This style is common in:

• announcements
• public notices
• workplace communication
• official instructions
• reports

A more casual version might be:

• 집결지에 마대와 쓰레기 집게를 놓았어요.

And an even more casual spoken version could be:

• 집결지에 마대랑 쓰레기 집게 놨어요.

So the original sentence has a polite, organized, somewhat official tone.

Yes, depending on how natural the English translation is.

Korean 에 covers several location-related meanings that English splits into different prepositions.

In this sentence, the natural English could be:

• at the gathering point
• in the gathering area
• to the gathering point if you are emphasizing where the items were placed

Because the verb is 놓다 (to place), English usually ends up using at, in, or on, depending on the noun and context.

So 에 does not map to just one English preposition. It marks the relevant location, and English chooses the most natural wording.

Usually it just means put/placed them there. It does not necessarily imply careful arrangement.

놓다 is broader than something like arrange. It simply means that the items were set down or placed in that location.

If Korean wanted to emphasize arranging things neatly, it might use different wording, depending on context.

So here, the sentence is most naturally understood as:

• the sacks and trash tongs were made available there
• the sacks and trash tongs were placed there

without any strong extra nuance beyond that.
