koko de sigenbutu wo kaisyuusimasu.

ここ means here.

The particle で marks the place where an action happens, so ここで means here / at this place as the location of the action 回収します.

That is why で is used:

• ここで資源物を回収します。 = Recyclables are collected here / We collect recyclables here.

If you used に, it would sound more like a destination, existence point, or result location, which is not what this sentence needs. Since collecting is an action happening at a place, で is the natural choice.

資源物 usually means recyclable materials or items that can be recovered as resources.

It is made of:

• 資源 = resources
• 物 = things/items

So the idea is not just trash, but things that can be reused or recycled, such as:

• paper
• cans
• bottles
• other recyclables

Depending on context, it may be translated as:

• recyclables
• recyclable waste
• recyclable materials

They are read as:

• 資源物 → しげんぶつ
• 回収します → かいしゅうします

So the whole sentence is:

ここで しげんぶつを かいしゅうします。

Or more naturally with normal spacing:

ここで資源物を回収します。

を marks the direct object of the verb.

Here:

• 資源物 = the thing being collected
• 回収します = collect

So:

• 資源物を回収します = collect recyclables

A good way to think about it is:

• を answers what is being collected?
• Answer: 資源物

Yes, in this sentence 回収します means collect or recover/collect for processing.

The dictionary form is 回収する.

This word often appears in practical or official contexts, for example:

• collecting recyclables
• collecting used items
• recovering materials
• collecting tickets or devices

It can sound a little more formal or administrative than a very casual English pick up.

Japanese often uses an active verb where English prefers a passive translation.

So:

• ここで資源物を回収します。

literally looks like:

• (Someone) collects recyclables here.

But in natural English, especially on signs or notices, this is often translated as:

• Recyclables are collected here.

The subject is omitted in Japanese because it is obvious or unimportant. The sentence does not need to say who is doing the collecting.

Possible implied subjects could be:

• we
• the city
• the staff
• someone in charge

So the Japanese is active in form, but the best English translation may be passive.

Yes, the subject is omitted.

Japanese very often leaves out the subject when it is understood from context or not important. In this sentence, the main point is:

• this is the place
• recyclables are collected here

The person or organization doing the action is not stated because it usually does not matter.

Depending on context, it could mean:

• We collect recyclables here.
• They collect recyclables here.
• Recyclables are collected here.

All of these can match the same Japanese sentence.

Yes. します is the polite -ます form of する.

So:

• 回収する = plain form
• 回収します = polite form

This makes the sentence suitable for:

• signs
• public notices
• announcements
• workplace or school instructions

A plain-form version would be:

• ここで資源物を回収する。

That might appear in very informal speech, notes, or certain written styles, but 回収します is more normal for polite public language.

Japanese word order is often:

[place] + [object] + [verb]

So here:

• ここで = at this place
• 資源物を = recyclables
• 回収します = collect

Japanese usually puts the verb at the end, which is why 回収します comes last.

A very literal breakdown is:

• Here, recyclables, collect.

That sounds strange in English, but it is normal Japanese structure.

Yes, but the nuance changes.

Original:

• ここで資源物を回収します。

This is a straightforward statement: Recyclables are collected here.

If you say:

• ここでは資源物を回収します。

the は adds contrast or topic emphasis. It can suggest something like:

• As for here, recyclables are collected
• Recyclables are collected here (though maybe not elsewhere)
• At this location, we collect recyclables

So ここで is more neutral, while ここでは can sound more contrastive or explanatory.

No. Other expressions are also common, especially depending on region or local government wording.

For example:

• 資源ごみ
• リサイクル用品
• specific categories like 缶, びん, 古紙

資源物 sounds official and practical, and you often see it in signs, collection notices, and municipal instructions.

So if you learn 資源物, that is useful, but you should know that Japanese may use different labels for recyclables depending on context.

Yes, very naturally.

It sounds like the kind of sentence you might see on:

• a recycling station
• a school or office notice
• a community collection area
• a municipal garbage guide

Because it is polite, simple, and official-sounding, it works well as sign language.

In English, signs might translate it as:

• Recyclables are collected here.
• Please place recyclables here for collection.
• Recyclables collection point.

The exact English wording may vary, even if the Japanese stays the same.
