Ok. Found some places where you can send your glass bottles for recycling. I read this article in the SCMP about April, the green activist who organizes dump trucks and volunteers to collect glass from various parts of Hong Kong.
They are spread out over different days, times and areas so I’d advise you to check before lugging all the glass you have down there.
This is the information for Wan Chai.
You should also refer to this link to confirm that the glass you’re sending is suited for recycling.
But here’s a quick graphic from their site to tell you what they do take (check out their site to see what they don’t).
P.s. You might also like to know that if you buy the glass bottles Kowloon Dairy milk, you can rinse and return for a dollar at any 7-11, PnS or Wellcome.
