How is the world dealing with the waste disposal epidemic?

It's become a problem of global proportions. According to the World Bank, around two-billion tonnes of waste is produced every year, and world leaders are struggling to figure out what to do with it all.  

Should it be buried, recycled or shipped off to another country?

It's a issue they are grappling with right now in East Delhi, India. They are fighting to contain a 65-metre high mountain of rubbish that gets larger every year.

Similar scenarios are repeated globally.

One of the problems is that recycling is now an estimated two-hundred-billion dollar industry, a huge incentive to limit what's done to change directions in the waste business.

So what are the answers?
