Green Iowa AmeriCorps is offering energy audits and weatherization services to residents of six cities in the state.

The organization is a community service program based at the University of Northern Iowa focusing on environmental education and stewardship. Free audits are open to Iowans in Cedar Falls, Cedar Rapids, Decorah, Des Moines, Dubuque, and Iowa City. According to Green Iowa AmeriCorps’ website, the audit process begins with an assessment of how much energy a home consumes. From there, home owners can learn about measures they can make to improve their home’s energy efficiency. Weatherization services specifically aims to seal drafts and prevent the loss of conditioned or heated air.

560 homes have been audited in Iowa City alone, according to The Daily Iowan. The program has operated in the city for five years. The audits can help lessen heating and air conditioning costs by offering home owners more insight on their residences. Alongside identifying potential problems, audits can also make corrections to a home to make residents more comfortable indoors.

Free audits can be signed up for via the Green Iowa AmeriCorps website or this Google Form. The audits do not have an end date yet.

Environmental groups speak out about consequences of holiday consumerism

U.S. shoppers spent $5 billion in 24 hours on Friday, making Black Friday 2017 a record haul for retailers. Whether it’s purchased online or in stores, the new Hatchimal or the Nintendo Switch, environmental activists warn that consumers should think twice about the impact these goods have on the environment.

Greenpeace, an independent global campaigning organization, reported that electronic goods alone are expected to generate 50 million tons of waste in 2017. Electronic goods like smart phones and laptops make up the quickest growing waste stream worldwide, less than 16 percent of which is expected to be recycled this year. About one-third of e-waste that is recycled is sent overseas to countries like Kenya and Pakistan to be taken apart by workers that are not protected from the toxic materials that can be found inside electronic gadgets.

Plastic is also a primary contributor to waste during the holiday season. Used for everything from toys to wrapping paper to grocery bags, more than 300 million tons of plastic is produced each year with about 8 million tons of it dumped into oceans annually. Plastic can take more than 400 years to break down and has mounted to form two enormous plastic islands in the Pacific Ocean, one of which is estimated to be more than one million square miles in size.

Friends of the Earth environmental activist Julian Kirby asked of holiday shoppers, “If you don’t need it or want it then don’t give them your money. If you are going to take advantage of what’s purported to be lower prices then don’t rush into it, think about whether it’s the most sustainable and ethical product and whether you might be able to get a second hand version that’s able to do just as good a job.”

On The Radio – 38 million pieces of trash found on remote Pacific island

This week’s On The Radio segment discusses how an extremely remote island in the Pacific ocean bares the highest litter density in the world. 

Transcript: Henderson Island is one of the most remote islands in the world and is also the most affected by pollution from plastic debris.

This is the Iowa Environmental Focus.

When researchers traveled to the tiny, uninhabited island in the middle of the Pacific Ocean, they were astonished to find an estimated 38 million pieces of trash washed up on the island.

The island is situated at the edge of the South Pacific gyre, where ocean currents meet in a vortex that captures floating trash, carrying some of it from as far away as Scotland.

Over 99 percent of the debris on the island is made of plastic—most pieces are unidentifiable fragments. The researchers say that fishing-related activities and land-based refuse likely produced most of the debris.

The researchers say the density of trash was the highest recorded anywhere in the world, despite Henderson Island’s extreme remoteness. The island is located about halfway between New Zealand and Chile and is recognized as a UNESCO world heritage site.

Converting food waste into energy

Wastewater treatment plants are on the cutting edge of renewable energy production, using technology that allows them to convert trash into valuable energy.

Food waste is first shipped to wastewater facilities, where it is mixed with sewage. The combined waste produces a gas, composed mostly of methane, that can be burned as fuel. In addition to this biogas, some facilities, like Des Moines’ wastewater treatment plant, are even able to produce an organic mixture that serves as an effective fertilizer.

This method is also beneficial to the environment, since methane is a greenhouse gas and would contribute to global warming if released into the atmosphere.

There are currently 15 facilities in the United States that utilize this technology, compared to thousands in Europe. Experts predict that this trend, along with composting, will continue to grow and innovate.

Nuclear waste research

A University of Iowa faculty member is researching how nuclear waste moves in environmental systems

Tori Forbes specifically studies uranium, a byproduct of nuclear fuel, and how it interacts in natural waters. The team will soon study at neptunium as well.

By better understanding how uranium and other nuclear chemicals react in the natural environment, new processes can be established to remove these chemicals safely and effectively.

Three Iowa City residents founded Greenway Bioplastics, a company that creates biodegradable tableware, to-go containers and more in an effort to keep waste from piling up and make some green.

The Des Moines Register reported on the efforts of Hicham Elhani, Can Dogan and Aziz Boussrhane, who have established a for-profit business that helps locals be more environmentally friendly.  Greenway is already working with seven local businesses and is looking to expand.

“Our aim is for nothing to hit the landfill, basically, and for it to be used another way,” Dogan said. Continue reading
