באופנה בת קיימא יש פחות פסולת טקסטיל.

The prefix ב־ means in or within. In Hebrew, short prepositions like ב־ (in), ל־ (to), and כ־ (as/like) are usually attached directly to the following word.

So:

באופנה = ב־ + אופנה = in fashion / in the fashion world

In this sentence, it sets the context: in sustainable fashion.

בת קיימא is a fixed expression meaning sustainable, viable, or able to last.

In modern Hebrew, it is very commonly used in phrases like:

• פיתוח בר קיימא = sustainable development
• אופנה בת קיימא = sustainable fashion

It is best to learn בת קיימא as one chunk rather than trying to translate each part literally.

Because אופנה is a feminine singular noun, and this expression changes to match gender and number.

Here are the main forms:

• בר קיימא = masculine singular
• בת קיימא = feminine singular
• בני קיימא = masculine plural / mixed plural
• בנות קיימא = feminine plural

Since אופנה is feminine singular, it takes בת קיימא.

Not in the usual everyday sense.

Normally, בת does mean daughter. But in בת קיימא, it is part of an old fixed expression, and native speakers understand the whole phrase as an adjective meaning sustainable or viable.

So in this sentence, you should not read בת as literally meaning daughter of. Treat בת קיימא as a set phrase.

יש means there is or there are.

Hebrew often uses יש to express existence in the present tense, where English uses there is/there are.

So:

יש פחות פסולת טקסטיל
= there is less textile waste

It does not mean has here. It is simply introducing the existence of a smaller amount of something.

Here, פחות means less or fewer, and it usually does not change to agree with the noun that follows.

So even though פסולת is feminine, Hebrew still says:

פחות פסולת = less waste

This is very normal. Think of פחות here as a quantity word, not as a regular adjective that has to match gender.

Grammatically, פסולת is singular and feminine.

But in meaning, it often behaves like a mass noun, similar to English waste. It refers to waste as a substance or category, not to individual countable items.

So:

• פסולת = waste
• פחות פסולת = less waste

That is why the sentence is talking about a smaller amount of waste, not fewer separate objects.

פסולת טקסטיל is a compact noun phrase meaning textile waste.

You can think of it as:

• waste from textiles
• textile waste

Hebrew very often uses a noun + noun combination like this instead of a longer phrase with של (of).

So rather than saying something like פסולת של טקסטיל, Hebrew naturally prefers פסולת טקסטיל here.

Because טקסטיל here names a general category or industry, not individual pieces.

This is similar to English phrases like:

• paper waste
• food waste
• textile waste

In all of these, the second word is not counting objects. It labels the type of waste.

So טקסטיל in the singular is completely natural here.

Hebrew often puts a phrase like באופנה בת קיימא at the beginning to set the topic or context first.

So the sentence structure is basically:

In sustainable fashion, there is less textile waste.

This word order sounds natural and helps highlight the context right away.

A different order such as יש פחות פסולת טקסטיל באופנה בת קיימא would also be understandable, but the given version emphasizes in sustainable fashion first.
