Reuse
From an environmental point of view it's best not to dispose things, but reuse them as much as possible. Reuse reduces the need for new materials and keeps your ecological impact down. If you have no use for something yourself, you can always try and see if someone else wants it, for example by selling it on eBay, or by giving it away to charity, to local thrift shops or on websites like The Freecycle Network.
2. Recycle
If something cannot be reused then recycling is a good option. Many types of materials can be recycled; glass, paper, metals, electronics, various types of plastic. You should check with your local waste facility which types of waste they accept for recycling.
Note that a recycling center may have specific criteria for certain materials. For example, most recycling facilities accept paper but not if it is greasy. This is because fats will interfere with the paper recycling process. What exactly is accepted for recycling differs from place to place. If you want to know more, I wrote about general guidelines a while back in my answer to 'How can I make life easier for my local recycling center?'
3. Incineration / Landfill
If something cannot be reused or recycled the only options that are left are incineration or landfill. These options are the least environmentally friendly.
Incineration has the disadvantage that materials are destroyed. However the heat from the incineration process can be reused for communal heating or for generating electricity.
Landfills have the disadvantage that disposed materials are not available anymore and that toxic materials may leach out from the waste and contaminate the environment. On the other hand landfilled materials that cannot be recycled today may be recyclable in the future. For example, in recent years old landfills have been opened to extract valuable metals. This is called Landfill mining
