Try www.earthagain.cc if you have books to give away. They collect books and convert into points so you'll be able to redeem items such as books, plants, fertilizer etc. They are slowly becoming a regular in One Utama.

For other things, you can donate to charity homes or those donation box (tesco puchong/ ttdi etc).

Recycle bins are also available around town, Damansara, Ikea/Ikano, schools too.

Hope that helps.
