IU To Turn GHG Emissions Into Plant Fertilizer

Nov 13, 2017

Indiana University wants to improve its sustainability – and it’s turning to a novel way of recycling to do so. The school’s main campus will turn its greenhouse gas emissions into plant fertilizer with the help of a photobioreactor.

The machine is made out of PVC pipe and will sit on top of the university’s central heating plant. There, it will capture plant emissions, which will be used to feed algae, which project co-leader Chip Glaholt says will be turned into plant fertilizer.

EPA Moves To Repeal Clean Power Plan

Oct 9, 2017

Environmental Protection Agency chief Scott Pruitt announced Monday the Trump administration will repeal the Clean Power Plan.

The Clean Power Plan would reduce carbon emissions from power plants by 30 percent nationwide in an effort to slow man-made climate change.

Indiana and 27 other states previously sued the EPA over the Obama-era rule.

The U.S. Supreme Court blocked the rule from going into effect in 2016, a move that met the approval of industry groups such as the Indiana Coal Council.

Five coal plants in Indiana ranked in the top 100 for both toxic and greenhouse gas pollution, according to a new analysis from the Center for Public Integrity.

That’s more “super polluters” than any other state in the country.

The Environmental Protection Agency has announced new fuel standards for big trucks, including a 25 percent cut to tractor-trailer emissions and fuel use in the next decade.

It's part of ongoing efforts to reduce greenhouse gas emissions. And it means big changes — and some potential new markets — for companies like trailer manufacturer Wabash National.

At the main Wabash factory in Lafayette, more than 3,000 people in hard hats and safety glasses assemble truck trailers from sheets of steel.

In a ruling issued Monday, the U.S. Supreme Court says the Environmental Protection Agency has the authority to limit the amount of greenhouse gases companies can produce—but it can only do so if the company is already required to get permits for other pollutants. Environmentalists and state officials in Indiana are declaring the ruling a victory.

Indiana joined 12 several other states in suing the EPA, alleging its new standards regulating greenhouse gases overstepped the authority Congress had given it.

Ever wondered who the big greenhouse-gas emitters are in your neck of the woods? The answer is now just a click away.

The US Environmental Protection Agency today unveiled a new website that identifies most of the nation's biggest emitters of carbon dioxide, methane and other greenhouse gases. It lets you, for example:
