I wrote about my class visit to the landfill (oh yes, I've been to TWO different landfills in the last six months) and about how that has impacted both my students and our school. Along with kicking butt in paper recycling (our Abitibi dumpster was filled to the brim today in our first post-spring-break recycling collection), we've slowly but surely started plastic bottle recycling.

Even our small school (320 students) generates a ton (figuratively) of plastic beverage bottles every day. I also mentioned that were were recycling our 20 ounce bottles through Terra Cycle's Bottle Brigade.

Terra Cycle, in short, rocks. Founded by Tom Szaky and Jon Beyer in 2001 while students at Princeton, Terra Cycle started as a way to spread the benefits of vermicomposting (that is, composting with worms) to a larger audience. For those out of the loop, worm poop is awesome fertilizer for your garden. Brown gold, if you will. Szaky and Beyer were eventually able to earn startup funds, and by 2004, Home Depot was carrying Terra Cycle Plant Food on their website.

Not only is their actual product eco-friendly, but their packaging is, as well. That's what happens to my kids' 20 ounce soda bottles: we send them back to Terra Cycle (sans label and cap), who pays us for the bottles. A nickle each. Anyone can do this, although you don't really get paid: the charity of your choice gets the money. This works for us, since technically, our school is a charity, so we can get paid. Terra Cycle takes those bottles, washes them, and relabels them. They add a trigger spray (a leftover from another corporation that produced too many) and the product is ready to ship.

Nowadays, you can still find Terra Cycle Plant Food at Home Depot, along with multiple other outlets. You can also join the Bottle Brigade, and Terra Cycle will send you prepaid shipping boxes to send them your 20 ounce bottles, which you can send back to them and donate your contribution to your favorite charity. More information on both the worm poop and the Bottle Brigade at Terra Cycle's website.

Poster and essay contests are widely-used avenues to engage students in environmental activism, but are often solitary activities that involve individual students.

For those teachers looking for something more hands-on, opportunities beyond the traditional poster contests challenge teachers and students to design creative solutions to environmental problems. Students benefit by having a structured setting to think critically and creatively, problem solve, and work cooperatively (not to mention the possibility of extrinsic reward for winning!) Sponsoring groups benefit by finding young talent and creative solutions that may be marketable and beneficial to both businesses, non-profits, and communities.

The Lifecycle Building Challenge, sponsored by multiple groups, including the EPA, Green Building Blocks, and the American Institute of Architects, challenges professionals and students to create buildings, building services, and/or building components that promote materials reuse throughout the entire lifecycle of a building, from design to deconstruction.

By creating buildings that are able to be reused or whose components are built with minimal material waste, contestants will design solutions that reduce the large environmental impact that comes from building and design. Students can enter in three categories: building, component, and service, and the top designs from each category can win multiple prizes, including $2500.

Canon's Envirothon is an annual competition in which students compete for scholarships by demonstrating their knowledge of environmental science and natural resource management. Student team are tested in multiple subjects and present orally in order to determine winners. One of the most extensive contests, there are numerous local and state Envirothons in which student groups can participate, with winners advancing to the national competition.

Finally, hip-hop band The Roots and non-profit Global Inheritance are teaming up to sponsor Feed Your Roots, a student contest to promote composting in schools. Student groups create a program that involves composting and design a poster with information for schools about composting. Winning schools will receive specially-designed compost bins autographed by The Roots themselves.

Contests such as these are interesting and atypical ways to move students from thinking into doing, and hands-on problem-solving allows them to create authentic solutions and make real change in the schools and communities.
