Target T.V. Ads “Go Green”

It’s always exciting when a big company that has such a influence on consumers decides to make earth friendly changes. Target is teaming up with EcoSet (eco-consulting firm) to make their television commercials more earth friendly. For example, on set, they’re using PLA utensils….I just hope they are discarding of those in a industrial compost facility! Read the article below to learn what other changes Target is making to their t.v. advertisements . Do you think these changes are enough, or do you think they could do better?

Target and EcoSet: TV Commercials Can Be Green Too

By Merlin Miclat on Mon, 08/15/2011 – 1:27pm

Many retailers these days have made significant progress in reducing their impacts on the environment. From implementing alternative energy to fuel their operations to carrying eco-friendly products, retailers are increasingly going green. However, Target and eco-consulting firm EcoSet, are taking it further by making television ads eco-friendly as well.

Target, which already carries a number of eco-friendly products, has teamed up with EcoSet to produce TV advertisements that are more environmentally responsible. The firm claims to have the ability to prevent 90% of waste produced on the set from ending up in landfills without interfering or costing production crews time or extra money. Also, since TV ad shoots last only a few days, crews usually do not take the time or put in the effort to clean up after the shoot. With tight schedules, why clean up if it takes up as much time as the shoot itself? This is where EcoSet comes in.

EcoSet is comprehensive in achieving its goals. On the set, there is not a single plastic water bottle; everyone is given a reusable, stainless steel water container. For Target shoots, everyone gets a red bottle labeled with a Target logo. Filtered water dispensers are provided for everyone to refill their water containers when necessary. How many times do people open a water bottle, take a sip, put the bottle down somewhere, leave, then come back and wonder which bottle was theirs? Then, just to be safe, they open up a new, sealed water bottle, and might repeat the whole process again. The use of reusable water containers and water dispensers would help eliminate this problem, which wastes water and plastic.

EcoSet also provides numerous recycling solutions. Waste from the set and office are recycled. Hazardous and electronic waste are also properly disposed of or recycled.

EcoSet also has composting bins to compost any food waste, which can be a big problem. In some cases, this problem has prompted groups to launch campaigns against production crews that waste food. For instance, Australian chef Matt Moran was angered when the prosciutto-wrapped chicken dish he prepared as a demonstration was tossed into the trash by a crew member.

Although the profanity-laced incident was admittedly staged, it emphasizes the problem with food waste. Chef Moran later explained, “I was more than happy to be involved in something so controversial if it meant that the message of food waste would be brought to the top of Australians’ minds.” Food waste can be used as compost; however, some chefs, especially those that spend much time and effort putting together dishes they are proud of, may be irked at the sight of their labors being composted and used to feed plants instead of being enjoyed by people.

Speaking of food, all dishware and utensils used on the set are either reusable or plant-based. Plant-based utensils are composed of renewable materials such as rice, corn, potatoes, and sugarcane. These utensils will biodegrade within 100 days, compared with traditional plastic utensils that take hundred or even thousands of years to decompose, taking up space in ever crowding landfills. These plant-based utensils usually conform to DIN CERTCO, ASTM, and ISO standards, assuring that they actually decompose in a timely manner as claimed.

Lastly, EcoSet has helped Target donate construction materials that are no longer needed on the set to various art and education organizations. Materials have been used for a variety of projects. Cindy Saucedo Smith, program coordinator for the organization ArtStart, has seen kids use materials such as silver cooling tubes as part of robot costumes. Says Smith, “The kids can go crazy when they see stuff like that, so we’ll hold on to it for the fall and see if there are suggestions for eco-costumes.”

As retailers may launch TV ads that claim how environmentally responsible they are, it is even better if producing these ads are green as well.

Pitt Researchers: Plant-Based Plastics Not Necessarily Greener Than Oil-Based Relatives

Biopolymers are the more eco-friendly material, but farming and energy-intense chemical processing means they are dirtier to produce than petroleum-derived plastics, according to study in Environmental Science & Technology

PITTSBURGH—An analysis of plant and petroleum-derived plastics by University of Pittsburgh researchers suggests that biopolymers are not necessarily better for the environment than their petroleum-based relatives, according to a report in Environmental Science & Technology. The Pitt team found that while biopolymers are the more eco-friendly material, traditional plastics can be less environmentally taxing to produce.

Biopolymers trumped the other plastics for biodegradability, low toxicity, and use of renewable resources. Nonetheless, the farming and chemical processing needed to produce them can devour energy and dump fertilizers and pesticides into the environment, wrote lead author Michaelangelo Tabone (ENG, A&S ’10), who conducted the analysis as an undergraduate student in the lab of Amy Landis, a professor of civil and environmental engineering in Pitt’s Swanson School of Engineering. Tabone and Landis worked with James Cregg, an undergraduate chemistry student in Pitt’s School of Arts and Sciences; and Eric Beckman, codirector of Pitt’s Mascaro Center for Sustainable Innovation and the George M. Bevier Professor of Chemical and Petroleum Engineering in Pitt’s Swanson School. The project was supported by the National Science Foundation.

The researchers examined 12 plastics—seven petroleum-based polymers, four biopolymers, and one hybrid. The team first performed a life-cycle assessment (LCA) on each polymer’s preproduction stage to gauge the environmental and health effects of the energy, raw materials, and chemicals used to create one ounce of plastic pellets. They then checked each plastic in its finished form against principles of green design, including biodegradability, energy efficiency, wastefulness, and toxicity.

Biopolymers were among the more prolific polluters on the path to production, the LCA revealed. The team attributed this to agricultural fertilizers and pesticides, extensive land use for farming, and the intense chemical processing needed to convert plants into plastic. All four biopolymers were the largest contributors to ozone depletion. The two tested forms of sugar-derived polymer—standard polylactic acid (PLA-G) and the type manufactured by Minnesota-based NatureWorks (PLA-NW), the most common sugar-based plastic in the United States—exhibited the maximum contribution to eutrophication, which occurs when overfertilized bodies of water can no longer support life. One type of the corn-based polyhydroyalkanoate, PHA-G, topped the acidification category. In addition, biopolymers exceeded most of the petroleum-based polymers for ecotoxicity and carcinogen emissions.


Once in use, however, biopolymers bested traditional polymers for ecofriendliness. For example, the sugar-based plastic from NatureWorks jumped from the sixth position under the LCA to become the material most in keeping with the standards of green design. On the other hand, the ubiquitous plastic polypropylene (PP)—widely used in packaging—was the cleanest polymer to produce, but sank to ninth place as a sustainable material.

Interestingly, the researchers found that the petroleum-plant hybrid biopolyethylene terephthalate, or B-PET, combines the ills of agriculture with the structural stubbornness of standard plastic to be harmful to produce (12th) and use (8th).

Landis is continuing the project by subjecting the polymers to a full LCA, which will also examine the materials’ environmental impact throughout their use and eventual disposal.
