Give away or resell usable items - consider Donate Seattle, craigslist, Freecycle, or look in the yellow pages under "Thrift Stores".

Some building supply second use stores may accept undamaged window glass.

Broken items go in the garbage. 

Only glass bottles and jars can be recycled in your curbside cart or at the transfer stations. Other glass items have different melting points and must be recycled with special processes.
