Airports go green with new eco-friendly initiatives

Airports are little cities unto themselves. Many are even large enough to have their own zip codes. With so many people coming in and out, cars dropping off and picking up, and planes departing and landing, airports produce a whole lot of air pollution and physical trash. But, many are making an effort to reduce their environmental impact by implementing new green features. Here are some of the coolest green initiatives at airports around the world.

Using Alternative Power
Last July, Boston Logan Airport installed 20 wind turbines that will offset about 3% of the building’s annual energy needs (doesn’t sound like much, but consider the amount an airport uses), and it’s not the only airport investing in alternative sources of energy. The airports of Munich, Zurich, San Francisco and Denver have also installed solar panels to help power their buildings. Dallas/Fort Worth Airport converted its bus and shuttle fleet to run on compressed natural gas and hydrogen-based fuel, as has Mineta San Jose. Heathrow is testing its new Personal Transport Pods, battery-powered, zero-emission vehicles that will whisk passengers from the terminal to the parking lot, and Boston provides preferred parking spots to drivers of hybrid cars.

Refilling Empty Water Bottles
The Portland Airport allows travelers coming through the security line with water bottles to dump the liquid but keep the container to refill once they pass security. That doesn’t sound like a big deal until you realize that other airports, like Chicago O’Hare, require the bottles to be thrown out. Not only does that policy generate tons of unnecessary waste, but all those full or half-full bottles weigh more and therefore the removal produces more emissions. Portland’s rule seems pretty green in comparison. San Francisco Airport goes one step further than Portland by providing water refill stations past the security checkpoint so people can refill their water bottles free of charge.

Recycling and Composting
Many airports have limited recycling programs in place, but some are going above and beyond when it comes to making sure that nothing that can be recycled gets added to a landfill. Seattle-Tacoma Airport, rated by the Clean Airport Partnership as one of the greenest in the country, charges concessionaires by the pound for waste(but doesn’t charge for recycling), encouraging vendors to recycle as much as possible. Portland makes it easy on flyers as well by providing a “single sort” recycle bin. Everything gets tossed in one bin and later sorted by a recycling company, so people don’t have to worry about which receptacle they throw their items into.

Seattle doesn’t end its recycling efforts with paper, plastic, glass and aluminum – it also composts 145 tons of coffee grounds per year and recycles 1,000 gallons of cooking oil each month, which is then used to produced biodiesel fuel. Munich Airport has a similar program: the organic waste from the airport’s restaurants is collected, sent to a farm, and used as pig feed. San Francisco hopes to require its concessionaires to serve all food in containers that can be composted and turned into fertilizer and Denver Airport will begin its own composting program this January.

Other green airport practices include using energy-efficient LCD screens on all computers and monitors, landscaping with native plants, installing low-flow toilets, and replacing paper towel dispensers with electric hand dryers. With the amount of waste and emissions airports produce as a result of their sheer size, the have a long way to go to truly be called “green”, but it’s nice to know that many are taking steps to reduce their environmental impact in whatever small ways they can.

How green is your hotel?

Not too long ago, any hotel that had one of those “please reuse your towels” signs in the bathroom was considered “green“. But with new hotels upping the ante by adding more features that reduce waste and environmental impact, it takes a lot more than that to truly be green. Here are some of the greenest hotel features to look for in an eco-friendly hotel.

Sheet and Towel Reuse Programs
Literally, this is the least a hotel can do. Asking guests to reuse towels and only changing the linens every few days or between guests no doubt saves water (and money for the hotel) but those positive contributions can easily be negated through other actions. If this all the hotel does, it might just be more frugal than green.

Bulk Toiletry Dispensers
Every time you check into a hotel, you’re provided with small bottles of face wash, body wash, lotion, shampoo and conditioner. Even if you’ve only used a minuscule drop, those bottles are tossed out and restocked at the end of your stay. This happens every day, for every room sold, at hotels all around the world. That’s a lot of tiny bottles clogging up landfills. The greener option being implemented in many hotels is to install bulk dispensers (similar to soap dispensers in public restrooms) that dole out small amounts of shampoo, soap and lotion without the extra packaging.

Local and Organic Cooking
Hotel restaurant chefs that use local, fair-trade, sustainable and organic ingredients get a gold-star for for being green. Using local products means that the food travels less to get to the consumer, which in turn means less energy is used and less emissions are added to the air from the planes, trains and trucks that transport food. Organic ingredients are created without the chemicals and pesticides that can harm the surrounding eco-systems, fair-trade products support local farmers, and sustainable foodstuffs are made in a way that doesn’t deplete the natural resources of the area. Hotels that employ these practices in their restaurants are doing something that is not only healthy for their guests, but is healthy for the community and environment as well. The hotel gets even more bonus points if some or all of the produce comes from the hotel’s own garden.

Green Lighting Practices
Replacing fluorescent light bulbs with ENERGY STAR certified compact fluorescent lights (CFLs) means that a hotel will use 75% less energy per year. While hotel guests can do their part by turning off all unnecessary lights when not in the room, some hotels, like the LEED-certified Orchard Garden Hotel in San Francisco, make this easier by requiring the lights to be activated by key card. The key card, usually attached to the hotel key, must be inserted into a slot in order to turn the lights on. Since you’ll obviously need to take the key and lighting key card with you when you leave the room, there’s no way you can leave the lights on while you’re out.

Green Building Materials
The buildings at Sadie Cove Wilderness Lodge in Alaska are constructed from scavenged driftwood, the mattresses and bedding at the Asheville Green Cottage in South Carolina are made from all organic materials, and the walls at Los Manos B&B in Colorado are built of local adobe and the ceilings are insulated with cellulose from old newspapers. All of these properties are using green building practices that help conserve precious resources. Using recycled, organic, scavenged and eco-friendly (like low-emission paints) materials in the building process makes a hotel green from the very beginning.

Reducing Water Usage
The El Monte Sagrado in Taos, New Mexico filters its wastewater into pure drinking water, but there are plenty of other ways hotels can save water that are a littler easier to do. Many green hotels install low-flow regulators in showers and toilet tanks, and some even put in automatic-timer showers that shut off after a certain number of minutes. (You can restart them with the push of a button, but the ticking clock serves as a powerful reminder to make it quick). Hotels in temperate areas have chosen to do their landscaping with tropical plants, which require less water to maintain.

Alternative Power
Many hotels are looking to alternative sources of power; the Alpine House in Jackson Hole, Wyoming, gets all of its power from wind turbines. Look for hotels that boast the use of solar and wind power for even part of their energy usage. Hotels that use shade trees and crosswinds to cool rooms, rather than air conditioning, also increase their eco-friendly factor.

Recycling Programs
All the paper used in the Hotel Triton in San Francisco, from napkins in the restaurant to stationary in the guest rooms, is made from recycled materials. Of course, after it’s used, it still gets tossed out. I’ve never seen a recycling bin in any hotel I’ve stayed in, and I highly doubt that housekeeping takes the time to separate recyclables from trash. As a result, plenty of paper, aluminum and plastic that could be recycled ends up getting tossed. Any hotel that offers recycling bins in the room is one step up on the green ladder.

Green Cleaning Products
Using non-toxic, all-natural cleaning products helps reduce the amount of dangerous chemicals that get into the water system and cause pollution. Look for hotels like Denver’s Queen Anne Bed and Breakfast which uses only baking soda to its clean tubs, sinks and toilets.

Other Green Practices
When combined with some of these larger-scale practices, the smallest acts can help make a green hotel even more eco-friendly. All Fairmont hotels offer free parking for hybrid cars, the Vancouver Hilton offers an alternative fueling station, and many hotels will provide free bikes for guests to get around on. Stocking guest rooms with glass drinking cups instead of plastic and relying on natural lighting as much as possible in public areas are two additional practices that make a big difference.

I doubt there’s any hotel that employs every single one of these practices. But it’s a safe bet to say that the more of these strategies a hotel uses, the greener it is. No hotel will have zero impact on the environment, but choosing a hotel that take does its best to use environmentally-friendly policies will help make your travels greener.

Is Turtle Airships just full of hot air?

On Tuesday, I wrote about Turtle Airships, a company that’s trying to produce a solar-powered amphibious “airship” capable of crossing the Atlantic. While we weren’t exactly flooded with responses over the post, we did get a few concerned comments from members of the Lighter-than-Air community. Yes, there is a whole community dedicated to blimps, zeppelins, and airships, and yes those are all different things (see, we’re learning so much here).

Apparently, there are some airship enthusiasts who aren’t quite convinced that the folks over at Turtle Airships have their heads on straight. Darrell Campbell, CEO and designer of Turtle Airships, would of course, beg to differ. The company’s slapdash website and offer of a free ride to anyone who ponies up $10 for an e-book doesn’t help their credibility, but poor marketing skills and a questionable product don’t necessarily make a company any less sincere.

Some skeptics say that the mechanics behind Campbell’s plan just don’t add up, while more vocal detractors think the whole thing is a ruse to swindle money out of the gullible. Only time will tell if they are right, so you may not want to buy that Transatlantic airship ticket just yet.

Solar airship will fly from NYC to Paris

First, let’s just get this out of the way: it is not, I repeat not, a blimp. Whew! Okay. . . Turtle Airships (a Spanish company that seems to have some intense aversion to the word “blimp”) is working on an airship that will make the journey from NYC to Paris, powered predominantly by the sun.

The top half of the blimp airship will be covered in solar panels that will store energy in batteries and use it to power four electric motors. The craft will also have a biodiesel engine as a back-up so the ship can fly in bad weather and at night. It will be able to take off vertically, land on ground or in water, and travel at around 40 miles per hour in ideal weather (making for a very long Transatlantic journey).

The airship is having a bit of difficulty getting off the ground at this point though, due to lack of funds. Turtle Airships is working on a prototype and hoping that as buzz for the project increases, so will the financing. Once the cash comes in, they say they’re ready for lift-off.

Until then, you can indulge your Goodyear fantasies with Airship Ventures, which offers Zeppelin flights from several California cities, ranging from $199 to $600 per person.

Solar powered plane to circle the globe

While Boeing and Airbus scramble to make larger, more luxurious planes, others are pushing the envelope in different directions, attempting to find ways to make them more energy efficient and environmentally friendly. Take the Solar Impulse for instance. This plane is setting the bar high, with a plan to circumnavigate the globe completely under solar power.

The Solar Impulse is the brain child of Bertrand Piccard, a Swiss adventurer and environmentalist, who launched the project back in 2003 with the aim of promoting the use of renewable energy sources. Now, in 2009, he is closing in on that dream. His plane has a 200-foot wingspan which is lined with 12,000 photovoltaic solar cells that will draw energy from the sun to power its four engines.

Piccard unveiled the latest design for his plane on June 26th in a ceremony near Zurich. This prototype will undergo test flights in 2010, including night flights using solar power stored in batteries. In 2011 the next design of the plane will be completed, with 2012 set as the tentative start of its world tour. The fact that this plane can fly even at night is one of the the things that separates it from other solar powered aircraft in the past.

While we might be years away from solar power becoming commercially viable for flights, it is projects like these that are paving the way for the future of flight. A future that is clean and environmentally friendly.
