-> "...recycling products (plural subject) no longer has (singular verb) much value"
They both must be products of the so-called public education system...this stuff just detracts from any legitimacy in the article.
My two cents: ...that (the) recycling (of) products no longer has value... ...that (the) products (of) recycling (efforts) have no value...
Recycling products is worthless, because recycling products are worthless! I love our language 😊
-> “...recycling products (plural subject) no longer has (singular verb) much value”
the verb in this case describes the action of ‘recycling’, which as used here is singular...’products’ is the object of the verb ‘recycle’...so the sentence is correct as it stands
