E-Waste

E-waste stands for electronic waste: all electronic products that we no longer use either because they no longer work or the technology is outdated. This includes laptops, desktop computers and monitors, cell phones, televisions, printers and fax machines, and all the smaller parts that come with them. Unfortunately, it is estimated that 60 million metric tons of e-waste enter US landfills each year, leaking harmful chemicals and making up 70% of the toxic waste in these landfills.

Fortunately, we can recycle these products instead of throwing them into landfills. They all contain useful resources, including glass, metals, plastics, and various minerals, that can be reused and diverted from the waste stream. Using the Tufts Eco-Map, you can locate collection sites to drop off your e-waste to make sure you are recycling it in a safe, effective way for both people and the environment. For more information about how to properly dispose of your e-waste visit the Tufts Facilities site.

Textile Recycling Stations Around Campus

According to Bay State Textiles, almost 21 billion pounds of textiles are thrown away every year in the United States; however, 95% of the textiles discarded can be recycled, and 45% of recycled textiles can be reused.

This year, committing to reducing your carbon footprint and helping those in need from campus just got even simpler. Donate your old clothes, shoes, sheets, towels, backpacks, and other approved items to the textile recycling stations around campus.

Look out for the sweater icon   on our Eco Map to find the closest textile recycling station near you!

Green Labs at Tufts

Labs are incubators of learning, innovation, and fostering the ideas for a better future, but labs also require large amounts of energy and resources. They require constant air circulation, energy-intensive equipment, and disposal of dangerous chemicals. Professor Kenny of the Tufts Chemistry Department has spent his career combining his two passions—sustainability, and chemistry. He has been a vital member of the Council for Sustainability of Campus Operations (sustainability council for short) and teaches an Environmental Studies core requirement, Chem 8: Environmental Chemistry, offered this coming spring semester.

This past summer, Professor Kenny and his Chemistry & Environmental Studies undergrad advisees Jonathan Ng and Patrick Milne conducted research in the prototype program Projects in Campus Sustainability, funded by the Council. These projects bring together faculty, students, and staff. Both Jonathan and Patrick’s projects focused on how to make the Pearson-Michael Chemistry complex a more sustainable lab space.

These projects grew out of a final paper written by Kirsten Hickey, an employee of the Chemistry Department, written for a class in campus sustainability taught by Professor Ann Rappaport.  Hickey’s paper described a number of areas in which the department could save energy and money while reducing its carbon footprint. Kenny transformed the report into a set of focused sustainability projects for which a cost-benefit analysis would be carried out by his students, with guidance from relevant faculty and staff.

Jonathan researched how to reduce the number of solvents used in research. Solvents are used in virtually every chemistry experiment and their disposal is expensive and energy intensive. Jonathan found that one solvent that was purchased for $3.70 per liter then cost $3.35 per liter to dispose of, meaning the total cost of using and disposing of the solvent is nearly double the initial purchasing cost. The solvents then need to be disposed of safely, often requiring hundreds of miles of travel to be properly disposed of. This high cost, both finically and environmentally, can be reduced by investing in a state of the art flash chromatography instrument that reduces both the amount of time and the amount of solvent needed for purification. Currently, the Pearson-Michael labs use an older, inefficient filtration system that requires a large volume of solvent. Jonathan is proposing that Tufts invest in the Reveleris® Prep System; the proposed new machine saves both time and solvent by optimizing the process on each trial using sophisticated software and an ultra-sensitive detector. This solvent saving machine would pay for itself in just two years while reducing the carbon footprint of Tufts labs.

Fume hoods are commonplace in chemistry labs, but do they need to be? That was the question driving Patrick Milne’s research \\project this summer. Fume hoods run constantly to remove any hazardous gasses produced by experiments. One of these hoods uses as much energy as three and a half average American homes, and there are 93 of them in Pearson-Michael. Regulating the air quality and protecting students from dangerous substances is the top priority of any lab, but Patrick determined that there was little or no need for General Chemistry 1 and 2 courses to do experiments that produce dangerous fumes. Altering the curriculum to do experiments that teach the same concepts but without the use of dangerous fumes is safer and more energy efficient. Most who take general chemistry continue on to take upper-level chemistry courses, so there is no need for these students to handle dangerous chemicals. Turning off or removing the fume hoods in the general chemistry labs would reduce Tufts energy consumption. Patrick also suggested that when fumes do need to be removed from an experiment, an extraction arm can be used. These extraction arms are more precise than fume hoods and filter the air more energy efficient than a fume hood.

Sustainable Chemistry Tips from Professor Kenny, Patrick, and Jonathan

Sustainable practices have only been integrated into teaching in the last few decades. Environmental awareness and thinking are increasing in labs, but as Professor Kenny explained, “unless special efforts are made to challenge ‘business as usual,’ people usually stick with what they learned.” Making students conscience of sustainable lab practices is the most important way to improve the sustainability of labs, both for now and for the future. Professor Kenny wishes for more research to be done on buildings and labs all over campus on ways to reduce waste and improve sustainability. Patrick and Jonathan hope to continue research and working on combining their passions for sustainability and chemistry in their future. Professor Kenny asks that “if anyone has ideas for projects that require collaboration between faculty, staff, and students come and see me and the sustainability council.” If you have an idea that could make Tufts more sustainable, don’t keep it to yourself; contact the Office of Sustainability or the Campus Sustainability Council with your ideas and help us create a more sustainable Tufts!

Give Thanks to the Earth: Tips for a More Sustainable Thanksgiving

What are you thankful for this Thanksgiving?  Your Friends? Your Family? Your health? All of these? Thanksgiving is a great opportunity to reflect on the year while surrounded by friends, family, and plenty of good food. What to give thanks to the Earth this year?

Here are a few tips on how to make your Thanksgiving plans more sustainable:

1. Consider Your Travel

According to the American Automotive Association, over 50 million Americans travel over 50 miles for their Thanksgiving meals. When traveling consider the impact of your flight and drive maybe stay closer to home this year. Remember that public transportation like buses and trains are much more efficient than driving in a car alone. Or try carpooling, Nuride is a great way for people living in Massachusetts to plan carpools. If you do leave home for the holiday, make sure to turn down the heat and unplug your electronics before you leave!

2. Reduce Food Waste:

What’s your favorite Thanksgiving dish? The mashed potatoes? Cranberry sauce? Pumpkin pie? Whichever it may be, keep in mind portion control; as difficult as it may be, take smaller portions because you can always get seconds. According to the NRDC around 40% of all food in the United States is wasted. Help combat food waste this Thanksgiving by cleaning your plate and saving your leftovers. Turn leftovers into delicious meals —leftover turkey and bones can make amazing soup or try making potato pancakes from mashed potatoes.

3. Go Meatless or Try Eating Less Meat:

The turkey is typically the centerpiece of any Thanksgiving dinner, so it may sound outlandish to consider going meatless this year. That being said, there are so many other delicious Thanksgiving dishes to be had, like mashed potatoes, kale, Brussels sprouts, green beans, and butternut squash soup. Even if you don’t want to go completely meatless, try putting less meat on your plate. The meat industry is a major contributor to climate change because of its methane production.

4. Use Reusable Dishware:

Prevent waste going into the landfill by using reusable napkins, dishes, silverware, and cups. In addition to being reusable, using real dishes brings a homier and warmer vibe to any meal.

5.Buy Local and Organic:

Local food is grown in your region and requires less fossil fuels and packaging for transportation. Organic food is grown without the use of pesticides which get into rivers and land and damage the ecosystems there. Organic and local food tends to be more expensive and this added cost is a barrier for many, but often goes on sale (find coupons and member sales with your grocery store’s rewards card). Whenever possible try to buy local or organic. Some farms even offer Thanksgiving CSA shares

6.Engage:

Thanksgiving is a time to reconnect with friends and family over a delicious meal. Have some open conversations with and share ideas, interests, and passions; including your passions for sustainability. If you struggle with discussing sustainability, then check out these tips from One Tree Planted.

Holidays are easy occasions to be swept into a buzz of consumerism and excess, so keep some these tips in mind and enjoy a happy and sustainable Thanksgiving!
