Why does the airport buy WORMS?

Charlotte/Douglas International Airport is the first airport in the world to invests 1.1 million Dollars on worms. The worms will be the core of the new recycling center, eating away a ton of travelers' trash every day.

Officials at Charlotte/Douglas International Airport in North Carolina are sure that a worm composting system will be the true key to reduce landfill footprint and to save money in the long-term.

According to the Charlotte Observer, the American airport will be the first to install this kind of system. However, it looks like other American airports are interested in following the example.

 

150kg of worms to reduce landfill footprint

In October 2011, it was announced that the airport will install a huge 2.5 km2 worm bin to host almost 150kg of worms. There the tiny crawlers will eat a daily ton of organic pre-compost made from travellers' trash (like food scraps, meat, bones, paper waste), other waste such as dirty bathroom towels, and plant waste.

In the same giant bin the worms will empty their stomachs and leave behind precious "castings". The castings will be collected and used as fertilizer on the airport's 6,000 acres of land. Any excess will be packaged and sold.

 

The investment will pay for itself in 5 years

The large-scale worm-based system is expected to open in February and it is part of the new $ 1.1 million airport's recycling center.

Investing in worms may sound a bit too risky for somebody. However, the airport officials say that, over the next 5 years, the recycling center will save the airport about $ 1 million in waste disposal costs, paying for itself.

Bob Lucas, who is in charge of the project said, "It's the right thing to do, it's good for the environment and there's nothing to lose to it". Lucas also added, "We're trying to reduce as much of our landfill footprint as possible".

Composting organic waste using a worm bin turns waste into a very rich fertilizer that can be used for plants and gardens. In addition, it keeps waste out of the landfill through a natural recycling process.

It is a very remarkable action by Douglas International Airport to invest on this more sustainable process. Hopefully other companies and organizations will think about it, too.
