Civil rights groups in North Carolina say ‘biogas’ from hog waste will harm communities of color

In a complaint filed with the EPA, the activists alleged that creating natural gas from methane in hog waste will increase ammonia pollution in the air and water.

From breakfast to biocrude: Study identifies production potential across nation

Cattle waste and wastewater. Sludgy grease ensconced in restaurant and cafeteria grease traps.  Food waste—uneaten leftovers or culinary mistakes. Contrary to the lyrics in The Sound of Music, these aren’t a few of our favorite things.

But when paired with waste-to-energy (WtE) technology, these things can become downright energetic—in the form of biofuels. These organic wastes serve as potential biofuel feedstocks, and they are available just about anywhere across the nation. However, industry lacks information about the locations of greatest concentration so it can boost biofuel production while giving human health and the environment a helping hand.

To shed light on this uncertainty, a team of researchers from Pacific Northwest National Laboratory (PNNL) and National Renewable Energy Laboratory performed a detailed analysis of these wastes’ potential for biofuel production on a site-specific basis across the conterminous United States. 

The results of the team’s analysis were published in Renewable and Sustainable Energy Reviews.

Turning hog waste into biogas: Green solution or greenwashing?

Read the full story at e360.

North Carolina’s industrial-scale hog farms have long been a major source of pollution. Smithfield Foods now plans to turn some hog waste into biogas, but critics say the project does nothing about the larger problem of waste being stored in lagoons and sprayed on fields.

We could power our homes with kitchen scraps. Here’s what has to happen first

Imagine if you could power your kettle using the energy generated from the vegetable cuttings quietly breaking down in your kitchen’s compost bin. That reality might not be so far off with the growth of biogas technology.

Webinar: The Multiple Aspects of a (Food) Waste to Biogas Project

The multiple aspects of a (food) waste to biogas project: Two case studies from UW Oshkosh Biogas Systems – One case study from a new anaerobic digester-urban farm project in Chicago.

Anaerobic Digestion of organic waste such as food waste is an alternative to landfilling that results in environmental benefits such as improved air quality, biogas recovery, and nutrients recovery. Anaerobic digestion projects are multifaceted ventures, and each has its own peculiarity. During this webinar we will discuss some of the many aspects of a waste to biogas project, featuring two existing facilities owned by the University of Wisconsin Oshkosh and one new digester-urban farm project under construction in Chicago and we will talk about available technical and educational assistance from the University of Illinois Chicago.

Producing renewable natural gas from manure could change future of power

Read the full story from Wisconsin State Farmer.

As farmers continue to innovate in environmental sustainability and find greener alternatives to traditional energy sources, manure digesters are becoming an increasingly important way to convert waste into reusable power.

Waste-to-energy supporters aim to ‘clear the air,’ reposition technology as landfill alternative

Recent research shows better performance across multiple environmental measures for WTE versus landfills, but few U.S. communities show an interest in new facilities, and opposition continues.

Pandemic garbage boom ignites debate over waste as energy

Read the full story from the Associated Press.

America remains awash in refuse as new cases of the coronavirus decline — and that has reignited a debate about the sustainability of burning more trash to create energy.

Waste-to-energy plants, which produce most of their power by incinerating trash, make up only about half a percent of the electricity generation in the U.S. But the plants have long aroused considerable opposition from environmentalists and local residents who decry the facilities as polluters, eyesores and generators of foul odor.

The industry has been in retreat mode in the U.S., with dozens of plants closing since 2000 amid local opposition and emissions concerns. But members of the industry said they see the increase in garbage production in the U.S. in recent months as a chance to play a bigger role in creating energy and fighting climate change by keeping waste out of methane-creating landfills.

Brightmark fires up waste plastic conversion plant

Read the full story in the Angola (IN) Herald Republican.

Brightmark started running its waste plastics-to-fuel conversion plant on Friday.

After weeks of testing, it was the first time the company has used the equipment on a full-scale basis to take plastic and turn it into either diesel fuel or commercial grade wax, said Bob Powell, president of Brightmark.

In a nutshell, waste plastic is turned into pellets on site. It is then fed into tanks known as pyrolysers and gets vaporized, then using a process called pyrolysis, the plastic is converted either to diesel fuel or wax.

One Person’s Trash Is the Biofuel Industry’s Treasure

Read the full story at Real Clear Energy.

Advanced biofuel companies have partnered with other parties to develop a two-step process to produce new types of advanced cellulosic biofuels. To support production of these new biofuels, processing facilities built next to landfills or trash sites breakdown specific types of garbage, paper, cardboard and other municipal solid waste to produce a liquid biofuel feedstock. This bio-intermediate, can then be sent to another facility for co-processing into renewable transportation fuels alongside petroleum to create a blended, advanced and renewable fuel.
