Learn Spanish (Spain): ¿Reciclarás el plástico?

¿Vas a reciclar...? means "Are you going to recycle...?" and is very common in spoken Spanish for everyday plans. ¿Reciclarás...? means "Will you recycle...?" and uses the simple future tense. Both are perfectly fine here, but the simple future can sound slightly more formal or refer to a more distant time.

How do you form the future tense for a regular verb like reciclar?

Unlike most tenses where you drop the ending, the simple future is formed by keeping the whole infinitive (reciclar) and adding the future endings. For tú (informal you), the ending is -ás, which gives us reciclarás.

Why is there an accent mark on Reciclarás?

When you add the -ás ending, the spoken stress falls on that final syllable. In Spanish, words ending in an "s" naturally have the stress on the second-to-last syllable. The accent mark is required to show that the stress breaks this rule and lands at the very end of the word.

How would I change this to ask "Will you recycle it?"

You would replace el plástico with the direct object pronoun lo (since plástico is a masculine noun). In Spanish, object pronouns go directly in front of the conjugated verb, so the question becomes ¿Lo reciclarás?.
