Another unusual field trip…

A little more than a week ago, my AP Environmental Science class went on another field trip. The trip, while not as scenic as our adventure at the farm,  was an eye-opening and surprising experience.

We visited a waste water treatment plant.

I know, I know, doesn’t sound pleasant at all. But it really only smelled badly for about 5 minutes of the entire 2 hour field trip.

The plant we visited serves more than 1.4 million people and covers 420 square miles. It transports, treats and reclaims all the wastewater produced by these people.

Our guide took us on a detailed tour of the facility. We passed large sedimentation tanks, bubbling vats of contaminant-eating bacteria, and roaring pumps. And yes, we wrinkled our noses a couple of times. I’ll spare you the details of wastewater treatment process, but if you are interested, click here.

One usually would not think of the technology at a wastewater treatment plant as sophisticated, but that’s exactly what it is – sophisticated. The plant is able to produce many valuable resources from our wastewater. Biosolids extracted from the water are digested by aerobic bacteria at 98 degrees Fahrenheit and used to fertilize forests or composted for use in landscaping and gardening. The digester gas produced by this biosolids digestion process is then cleaned and used as an energy source.

The term “wastewater treatment” is misleading. It makes us think we can flush anything down the toilet or drain anything down the sink, and it will just go away and be cleaned. In truth, wastewater treatment is highly expensive, and many of the costly problems that occur at the plant are due to inappropriate disposal of trash. Putting trash, wipes, grease and hair into the sewer system clogs pipes and can create sewer overflows. This in turn will have a negative impact on the environment.

In the kitchen, it is best to compost your food scraps. Some areas allow you to throw food scraps into your yard waste bin. Or, you can compost your food yourself, either by making a worm composting bin or burying your food scraps. To learn more, click here. Remember, grease, fats, oil, and produce stickers should not go down the kitchen drain!

In the bathroom, if it isn’t toilet paper, put it in the trash can or recycling bin, not the toilet. Many people used to think it was okay to flush expired or unused medications down the toilet. But conventional wastewater treatment is unable to remove all the chemicals found in medications. Scientists have found that this practice is harming aquatic life. More and more male frogs and fish are developing female characteristics, leading to reproductive difficulties.  Keeping medications out of the sewer systems will also protect our drinking water. To properly dispose your old medicine, visit your city’s or county’s hazardous waste site, and see if medicine is listed. Some states, including Washington, also have special medicine take back programs.

This trip made me realize my water doesn’t just go away when I’m done with it. I need to think about what exactly I am putting into it, so it stays clean in the future.

Making Fido and Fluffy more green

I love animals – there’s no doubt about that. I’m the type of person who is willing to capture a spider and release it back outside instead of just using a Kleenex to swiftly finish the job, who feels sorry for the worms stuck on the pavement after it rains, and who tried to let the crabs escape when her family went crab-fishing when she was younger.

I especially love my fluffy, yappy Pomeranian, Jamoca.

So when I began hearing about domestic pets’ large carbon footprints, of course I resisted at first. Jamoca is so adorable and perfect (except for the occasional accident on the carpet), how can she have any effect on carbon emissions?

But according to BBC, the average cat contributes to 0.5 tons of CO2 a year, while the average dog contributes to 1.5 tons a year. When I finally pushed my strong bias for animals aside, I realized pets contribute to carbon emissions in many of the same ways people do – mainly through food and waste.

Dogs and cats need food, and most of the dry kibble Fido eats is made from leftover materials meat industries don’t want, meat from cows that are dead, dying, diseased, or disabled. The large meat industries that bring us our cheap beef also create a lot of waste and carbon dioxide simply by the way they raise their livestock. For more information about the environmental impacts of the meat industry, you can read my earlier post

Some people advocate putting pets on a vegetarian diet. I personally find this solution a little extreme. Dogs and cats, after all, are naturally carnivores. But you can still put your pet on a healthier, more natural meat-based diet. Organic pet foods made with meat raised in sustainable ways without growth hormones or antibiotics are easy to find at pet stores, if you are willing to spend the extra money. Or, you can make your own pet food, so you have complete control over what goes into it. is a useful website for recipes. But before you feed your furry friend homemade food regularly, make sure your talk to your veterinarian first to ensure your pet gets the nutrition it needs.

Okay so we’ve now talked about what goes into your pets…now we have to talk about what comes out.

According to Mark Klaiman in the article “Litter and the Environment,” most kitty litter is made from clay. This clay must be strip-mined, disturbing large areas of land. The clay then must be transported and processed, which requires more energy resources. Finally, when the litter ends up in landfills it just sits there forever.

The best alternative is to use biodegradable kitty litter. Old shredded newspaper works well too. For directions on making your own cat litter, visit

Dog waste is a little more difficult to manage. But first, obviously, pick it up! Not only is this polite (your fellow citizens will be very grateful!), but this prevents harmful bacteria from contaminating local waterways. But what do you do after you pick it up?

Most people use plastic bags and then throw them in the trash. But like with clay kitty litter, the waste sits in landfills for basically eternity. One alternative is to flush it down the toilet where it will get treated in a sewage plant. Using biodegradable plastic bags also helps somewhat.

The best alternative, though, is to compost your pet waste. There are two main ways to do this. The first method is called trenching, which basically means you bury the pet waste underground to provide nutrients for garden plants. However, you should only plant ornamental plants above the trench, never vegetables or fruits. For directions on how to trench, visit

The second method is to build your own dog waste composter. All you really need is an old garbage can, some rocks, and septic starter. For step by step directions, visit Choose a sunny site that is away from vegetable gardens and waterways. This composter is actually good for both dog waste and biodegradable kitty litter. Collect the pet waste and drop it into the composter. Sprinkle two of the packets of septic tank starter on top of the pet waste and about a quart of water. Cover the hole with the lid. After 48 hours you can add more pet waste. You can then begin to add it daily.

From what goes in to what goes out, making our pets more green takes effort. But then again, isn’t that just another way to show our love? According to BBC, some scientists warn small heartworms that kill dogs and cats are on the rise in some areas due to warmer and wetter summers.

Greening up Valentine’s Day (Part 2)

Valentine’s Day is a week away! Here are some more eco-friendly Valentine ideas!

A bouquet of a dozen roses is a traditional gift on Valentine’s Day. But many floral industries grow their flowers unsustainably and dump buckets of pesticides into the environment. is a very useful website where you can find local farms that grown organic flowers. Or, if you still want to purchase a bouquet of flowers, look for the Veriflora tag. Flowers with this label must follow strict standards for environmental sustainability. 

Another unique idea is to give a plant or flower you planted and raised yourself, like these baby pine trees my sisters planted last year.

When it comes time to actually give the gift, why spend $4 on a gift bag when you can make one yourself from a cereal box?

Remember Reduce, Reuse, and Recycle? Recently, it’s the last “R” that has gotten the most attention. Of course this is a good thing. But just recycling isn’t enough. Recycling requires a substantial amount of energy. Some materials, including plastic and glass, take more energy to recycle than to manufacture.

Therefore, it is important to reduce our use of a material (decreasing the initial amount of material that needs to be manufactured) and also to reuse materials (unlike recycling, this does not require energy, except maybe human energy and creativity)

These gift bags are very easy to make and perfect way to reuse a lot of materials lying around the house.

First, cut the flaps off the cereal box. Then  paint the box a desired color or cover it with recycled paper. I used paper from printing mess-ups. Decorate the box with old colored paper and magazines. Punch a hole at the top of each side of the cereal box. Finally, attach a ribbon to the holes to make a handle.

Greening up Valentine’s Day

Valentine’s Day is coming up, which means chocolates, roses, cards and a lot of pink. But why not make Valentine’s Day a little bit more green as well? In the next couple posts I will be providing ideas for a traditional Valentine’s Day with an environmental twist.

First idea: homemade chocolates

Skip the store-bought candies to cut down on packaging and artificial ingredients. Plus, in my opinion, homemade treats are so much sweeter.

Here is a simple recipe for truffles.


3 (1 ounce) squares bittersweet chocolate (I used 72% dark chocolate, you can also use organic chocolate if you would like)

1 cup sifted confectioners’ sugar

1/3 cup butter or vegan butter

3 egg yolks

1 teaspoon vanilla

Ground nuts, sprinkles, or other favorite coating


Melt 3 chocolate squares in microwave.

Cream sugar and butter in mixing bowl. Add egg yolks one at a time; blend well after each addition. Stir in melted chocolate squares and vanilla. Chill mixture in refrigerator until firm enough to handle easily. Break off small pieces to form into 1/2 inch balls. Roll in a favorite coating. Allow finished truffles to dry and firm on baking sheet about an hour before storing in airtight container in very cool place.

These truffles keep about a week.

When giving these truffles as gifts, you can put them in one of those glass jars lying around in your kitchen. For a pretty pattern, you can alternate between a layer of truffles and a layer of marshmallows. Tie a ribbon around the jar for a finishing touch.

More green Valentine’s Day ideas coming soon!
