Is it normal for glass bottle scrap to require colour-sorting before any buyer will take it?
Short answer: Many glass recycling processes do require or strongly prefer colour-sorted glass, since different colours are used for different manufacturing purposes and mixing them can limit what the resulting recycled glass can be used for — some buyers will accept mixed-colour glass at a lower rate or for a more limited end use, so check what a specific buyer requires before assuming either sorted or unsorted is universally expected.

Clear, green, and brown glass are typically manufactured and used differently, and mixing colours during recycling limits the resulting cullet to lower-value, less flexible end uses — this is a genuine processing consideration, not an arbitrary preference, which is why colour-sorting is commonly requested or preferred.
What happens with unsorted, mixed-colour glass
Some buyers will still accept mixed-colour glass, but typically at a lower rate reflecting its more limited end-use options compared to properly colour-sorted material — this isn’t universal rejection, just a price reflection of reduced processing flexibility.
Whether sorting is worth the effort for you
For a larger volume of glass, sorting by colour before selling can capture a meaningfully better price, while for a small amount, the time cost of sorting may not be worth the modest price difference — this depends on your specific volume and how much time sorting would actually take.
How ScrapTrade Makes This Easier
Listing glass sorted by colour on ScrapTrade, even roughly, typically draws more specific offers than an unsorted mixed-colour listing described generically.
