Elena, WASTE is collective

Uly, industrial wastes are meant: http://www.thefreedictionary.com/waste.

I know exactly what it means, I'm talking about the plural form WASTES, which looks and sounds horrific. We consider waste a collective noun, so when we wish to pluralize it, we put a plural word with it: waste materials, waste products, etc.

Here is a google search for the exact words "non-recyclable wastes." Notice that in the results, all the instances of "waste" are collective: https://www.google.com/#q=%27non-recyclable+wastes%22&start=10

By the way, I didn't vote you down.

Here's a search for "industiral wastes" - even though I entered the plural form, all the results are collective: https://www.google.com/#q=%27industrial+wastes%22

Here's an N-gram of "reduce industrial waste" and "reduce industrial wastes" - notice that the plural variant doesn't even register on the gram, meaning that it doesn't appear even once in the millions of books that the Ngrams are based on.
