Year-round E15 available for consumer access


By Julia Shanahan | June 13th, 2019

President Donald Trump recently approved the sale of year-round ethanol for consumer access – a move that was applauded by Iowa’s Republican Senators Chuck Grassley and Joni Ernst.

In a joint press release from Grassley, Ernst, and Iowa Gov. Kim Reynolds, they commended Trump for “keeping his promise” to Iowa farmers.

“[Trump’s] directive to EPA to finalize a rule allowing year-round sales of E15 will allow for an open marketplace with more fuel options, encourage competition and drive down fuel costs — all while improving the environment,” said the June 11 press release.

Trump made an Iowa campaign stop on June 11 in Council Bluffs and West Des Moines, where he touted his approval of year-round E15 to farmers and manufacturers in Council Bluffs. E15 is championed as something that could boost Iowa’s economy because of the use of corn in its manufacturing.

E15, a gasoline blend with 15 percent ethanol, burns cleaner than standard fuel and can be used in all 2001 and newer vehicles. Burning ethanol does result in the emission of greenhouse gas, but when the combustion of ethanol is made from corn or sugarcane, it’s considered atmospheric neutral, because the biomass grows and absorbs CO2.

As of March 2019, Iowa’s ethanol industry has accounted for 43,697 jobs and $4.7 million in GDP, according to the Iowa Renewable Fuels Association. In 2018, there was 4.35 billion gallon of ethanol production.

In a 2016 editorial from the Yale School of Forestry & Environmental Studies, a professor of food and agriculture policy wrote that increasing corn production in the Midwest for ethanol use has repercussions on the environment, and questioned the profitably of the ethanol industry. He referenced ethanol production taking off in the mid-2000s and corn prices reaching record highs in 2007.


However, the USDA cites other contributing factors to the high corn prices, including the depreciating U.S. dollar, bad weather, and policy responses on imports and exports of commodities.

South Sioux City to become “demonstration site” for stored electrical power


Julia Shanahan | June 7th, 2019

South Sioux City, located in northeast Nebraska, will become a “demonstration site” this winter for the storage of electric power generated by the city’s 1,200 solar panels.

A large battery, described as a “semi trailer without wheels”, will be able to store 1.5 megawatts of power and cost about $1.8 million, according to a report from the Iowa-based Sioux City Journal. This project is a big step in the field of renewable energy because power would be able to be stored for days with less wind or sunlight.

The report also said that solar energy makes up roughly 5 percent of the city’s electricity usage, and that South Sioux City now gets about half of its electricity from renewable sources, like solar, wind, and hydroelectric power. In Iowa, about 2 percent of renewable energy comes from a source other than wind.

The city hopes to continue taking steps to lessen its dependence on the Nebraska Public Power District, and eventually fully phase out of their contract.

As South Sioux City takes steps toward utilizing sustainable energy, Iowa remains a leading state in the field of renewable energy.

In 2018, Iowa’s 3,400 wind turbines produced 34 percent of the state’s electricity – the second highest share for any state, according to the U.S. Energy Information System. Additionally, among the top five energy-consuming states, Iowa was the only non-crude oil-producing state on a per-capita basis in 2018.

Iowa also remains the largest producer of ethanol in the U.S., producing one-fourthof the country’s ethanol production capacity.

Iowa passes new bill on advanced plastic recycling

The Iowa Legislature and Governor Reynolds passed a bill this week in support of chemical recycling facilities for plastic in the state.

The bill defines gasification and pyrolysis, two chemical recycling methods, as processes that convert waste plastics into raw materials like crude oil, gasoline and other chemicals by heating and melting them in oxygen-deficient environments then processing them accordingly.  Those materials can be used to make new plastic products or as “feedstock” to fuel industrial processes. Plants conducting these activities in Iowa will be regulated more like manufacturing plants than solid waste disposal facilities, according to the trade publication Plastics Recycling Update.

There are obvious benefits to recycling plastics. Transforming plastic waste into useful materials will keep it out of landfills, rivers and oceans. A National Geographic story on plastic recycling said that pyrolysis plants can handle filmy plastic bags, which most traditional recycling plants cannot. Recycling also reduces the amount of new material that must be manufactured to meet demands.

Recycling Today reported that five advanced recycling facilities could generate $309 million annually by converting 25 percent of Iowa’s plastic waste into industrial feedstocks or transportation fuel. According to National Geographic, however, it is still cheaper to make diesel from fossil fuel than plastic. The article said pyrolysis startups have closed in the past because they haven’t been able to make money or meet pollution control limits.

Burning plastics releases carbon and toxins into the atmosphere, albeit at fairly low rates  according to industry experts. Michigan State University Extension says gasoline and diesel produced from plastic appear to contain more energy and less carbon that traditional fossil fuels, too.

Plastics Recycling Update said the Iowa Recycling Association had been opposed to the bill but did not say why. This post will be updated if and when the Iowa Environmental Focus is able to learn more.

This weeks segment looks at BP’s place in the coming decades with rising demands for renewable energy.

Transcript:

BP Oil and Gas has made energy demand predictions about the future—but are they accurate?

This is the Iowa Environmental Focus.

After the massive oil spill along the Gulf Coast in 2010, BP became known globally in a decidedly negative light.

Almost a decade later, and with settlement payments still being paid out, the energy company has thrown its weight behind renewable energy. BP outlines in its annual energy outlook that the planet could run on mostly renewable sources by 2040.

There is a small detail that some environmentalists find troubling, however; the BP report also lists an estimated rising global demand for energy well into the 2040s, while other scientific reports estimate that global demand will taper off and even out by the 2030s.

A rising global demand for energy is a given, as underdeveloped countries begin working on their infrastructure and making improvements for their citizens. But overestimating how much energy will be needed globally in the future could allow oil companies to continue selling more fossil fuels, even as renewable energy use grows.

On The Radio- Endangered Insects

This weeks segment is not an April fools joke; bugs could disappear within the next century.

Transcript:

At their current extinction rate, insects could completely disappear within a century. 

This is the Iowa Environmental Focus. 

Insects are disappearing eight times faster than mammals, reptiles, and birds. One in three species is endangered, and the world’s total mass of insects has been dropping 2.5 percent annually, according to a new scientific review. 

It’s well known that losing bees will reduce pollination for some of our favorite fruits and nuts, but devastated insect populations will leave other critters hungry as well. Insectivores and their predators will starve if insects disappear. 

Researchers from the University of Sydney and the China Academy of Agricultural Sciences analyzed 73 previous studies to assess the state of global insect populations and determine the cause of decline. 

They believe intensive agriculture is the main driver. Wildland is increasingly converted to farmland, and new pesticides like neonicotinoids seem to “sterilize” the soil, killing larvae before they can move to safety, one researcher told the Guardian News.

CGRER Looks Forward: Anthropologist Matt Hill

In their relatively short residence on Earth, humans have survived several dramatic climate change events, albeit with more natural causes than at present. They have endured man-made environmental challenges, like deforestation, as well.

So could the key to modern climate adaptation lie in the triumphs and mistakes of ancient civilizations? Matthew Hill, associate professor of anthropology at the University of Iowa, sees potential.

“I think that you can use the past—carefully—to see patterns, see how certain strategies were attempted to deal with these environmental changes and see whether they have failed or succeeded,” Hill said. “I see it as one helpful guidepost to how people have responded to similar changes.”

Anthropology, broadly, is the study of human cultures. Hill primarily focuses on human interactions with the environment. As an archaeologist, he spends a lot of time studying ancient peoples and their technologies—specifically, how indigenous hunters interacted with animal populations in North America.

Hill describes his research on ancient North American peoples and animals. 

One of his earliest studies involved North American bison. They sustained native populations in the Great Plains for tens of thousands of years but declined rapidly once Europeans joined the hunt. Hill sought to understand the differences in strategy and mindset that led to dramatically different outcomes for bison before and after colonization.

About half of Hill’s recent research focuses on modern humans, too. With an interdisciplinary team of Iowa researchers, he is studying the social and environmental positions of wood-burning stove users in rural India.

“We’re trying to understand how these women are coping and adapting to a changing environment, one in which there’s deforestation and one in which governments and international organizations are targeting their way of life for change,” he said.

Hill discusses his research on biomass burning in rural India. 

Adaptation is the common thread throughout Hill’s projects. In both past and present peoples, he has examined a number of successful and failed strategies for dealing with all sorts of environmental problems.

As he sees it, innovation is not an issue. He said people have always been clever and able to develop new technologies and approaches. The bigger problem seems to be motivating political and economic elites to work towards positive change.

“Even if there’s goodwill, there’s not a single direction that a country or large group moves toward,” Hill said. “It’s often contradictory forces.”

Hear Hill’s thoughts on the political reality of environmental action. 

The masses often have more incentive –they are harmed by environmental isues far more than elites – but the poor and disenfranchised typically lack adequate resources to be a “positive push forward,” he said. It is up to leaders to be proactive and implement solutions that work for everyone.

But still, successful adaptation is possible. Hill pointed to North American big game hunters as evidence. At the end of the paleolithic Ice Age they faced mass extinction of food sources like mammoths and mastodons.

Amazingly, they managed to “not just survive but thrive,” he said. He attributes thoughtful resource management and long-term planning to their success.

“We can only hope that American society can point to these kinds of behaviors,” Hill said. “Not just thinking about next quarter or the next year, but thinking about the next generations, we too can not just survive change, but flourish in the face of change.”

On The Radio- Insect based dog food

This weeks segment looks at new methods of creating dog food with less of an environmental impact. 

Transcript: 

A potential new insect based dog food could help the planet. 

This is the Iowa Environmental Focus. 

Meat production has been linked to increasing emissions of CO2 and methane into the atmosphere. This is the reason many environmental activists choose a vegetarian or vegan diet but humans aren’t the only mammals reliant on meat.

Pets are estimated to eat twenty percent of the meat produced world wide. A pet food manufacturer in the United Kingdom, Yora,  has introduced black solider flies as a protein substitute. Along with less emissions into the atmosphere, the black solider fly based dog food is cheaper to produce and requires less land and water.

At the Royal Veterinary College, pet diet expert Aarti Kathrani confirmed that soldier flies could meet a canine’s nutritional needs. She told the BBC,  “insects can be a very useful source of protein. More studies are needed to show how much of these nutrients can actually be absorbed by a dog’s body- but some studies suggest that insects can provide nutrients for dogs.”

Yora is not the only pet food manufacturer to use flies in their recipe but other manufacturers typically use only a small amount. Yora is currently planning to transition forty percent of their products to majority fly protein.
