Most people would consider garbage as stinky and are just mere waste materials. But for some people, there are actually valuable things that are like gold bullion hidden masked by rubbish.
That because there are people who know processes that convert the seemingly worthless garbage into useful things.
For example, if garbage is properly segregated, organic fertilizer can be made out of them and sold at premium prices.
Other things that look like junk can still be sold to other people for a much lower price. But if these are in large quantities, that could mean a whole lot of money!
But even if we do not make money from our garbage, we can lessen our wastes by segregating and giving away those things that can still be used by other people. We can also gather those recyclable materials that we can sell to the junk shop. These may not be things that will make us rich but at least we can help lessen the garbage volume in our cities.
