حاوية إعادة التدوير في المساحة الخضراء.

It can be understood as a full sentence in Arabic.

Arabic often uses nominal sentences in the present tense with no written or spoken word for is/are. So this can naturally mean:

• The recycling container is in the green space.

In another context, it could also function as a label or caption, like a sign naming an object and its location.

Because حاوية is the first word in an iḍāfa (construct phrase).

In an iḍāfa:

• the first noun does not take الـ
• the whole phrase becomes definite if the final noun is definite

Here the structure is:

• حاوية = container
• إعادة التدوير = the recycling

So:

• حاوية إعادة التدوير = the recycling container

Even without الـ on حاوية, the whole expression can still be definite.

It is another iḍāfa inside the larger phrase.

Breakdown:

• إعادة = re-doing / repetition / re-
• التدوير = cycling / processing / turning

Together, إعادة التدوير is the standard Arabic expression for recycling.

So the sentence contains a nested structure:

• حاوية
  • إعادة التدوير
• literally: container of recycling

This kind of noun chaining is very common in Arabic.

In present-tense Arabic, the verb to be is usually omitted.

So Arabic says:

• حاوية إعادة التدوير في المساحة الخضراء
• literally: recycling container in the green space

but the meaning is:

• The recycling container is in the green space.

If you wanted a past or future meaning, Arabic would usually add a verb, for example:

• كانت... = was
• ستكون... = will be

Because الخضراء is the adjective agreeing with المساحة, and المساحة is:

• feminine
• singular
• definite

Arabic adjectives must agree with the noun in:

• gender
• number
• definiteness
• case

So:

• المساحة = feminine singular definite
• الخضراء = feminine singular definite adjective

If the noun were masculine, you would use الأخضر instead.

Because in Arabic, adjectives come after the noun.

So:

• المساحة الخضراء = literally the space green
• natural English: the green space

This is one of the biggest word-order differences between Arabic and English.

The same rule applies throughout Arabic:

• بيت كبير = a big house
• السيارة الجديدة = the new car

If read as a full nominal sentence, it would typically be:

حاويةُ إعادةِ التدويرِ في المساحةِ الخضراءِ

Why those endings?

• حاويةُ: nominative, as the opening noun of the sentence
• إعادةِ: genitive, because it is in iḍāfa after حاوية
• التدويرِ: genitive, because it completes the inner iḍāfa
• المساحةِ: genitive, because it comes after في
• الخضراءِ: genitive, because it is an adjective matching المساحة

In normal everyday writing, these short vowels are usually not written.

A helpful pronunciation is:

ḥāwiyat iʿādat at-tadwīr fī al-masāḥah al-khaḍrāʾ

A few pronunciation notes:

• ح is a strong breathy ḥ
• ع in إعادة is a deep throat sound
• تدوير is pronounced roughly tad-weer
• الخضراء ends with -āʾ, a long vowel plus a glottal stop

Also, in careful pronunciation, الـ before ت in التدوير is assimilated, so it sounds like:

• at-tadwīr, not al-tadwīr

Not specifically by itself.

حاوية is a general word meaning:

• container
• receptacle
• bin

In this context, because it is followed by إعادة التدوير, it means a recycling container/bin.

Depending on context, English might translate it as:

• recycling container
• recycling bin

Both are reasonable.

Because إعادة التدوير is the standard full expression for recycling in Modern Standard Arabic.

The idea is re-cycling / re-processing, so إعادة adds the sense of again / re-.

Using just التدوير would usually not be the normal standard term for recycling in this context. For learners, it is best to treat إعادة التدوير as a set expression.
