Adding Value to Biofuel Waste

Posted in Climate, Plants, tagged , , on 06/09/2014|

Screen shot 2014-06-09 at 3.47.19 PMWhat do you get when you cross E. coli with biofuel waste products?  A new process that may revolutionize the economic development of the growing biofuel industry.

Biofuels represent the best sustainable, secure, and renewable alternative to fossil fuels. Unfortunately, biofuel production is beset by the same problem as traditional petroleum refining – excess waste. In traditional refining, only about 60 percent of the crude oil becomes gasoline, the rest is used to make other products. Similarly, as biofuel production increases, the market is being flooded with its waste byproducts, specifically glycerin, also known as glycerol.

Glycerin is cheap and abundant in the current marketplace. Although there are many potential uses for the substance, it is difficult to break it down into products with greater economic value.

Trees: A Poplar Source for Biofuels

Posted in Climate, Plants, tagged , , on 06/09/2014|

There is no simple solution to the energy problem. Crops, such as corn, compete with the food supply. Poplars and other trees could provide a sustainable alternative for ethanol production; however, they require costly pretreatment before processing into ethanol. Researchers at North Carolina State University (NCSU) have identified a potential solution to the problem.

Currently, the ethanol industry provides about four billion gallons of ethanol to the fuel market, which is expected to grow. Developing a process that effectively makes ethanol from cellulose derived from different types of plant biomass, particularly wood, remains difficult due to one significant barrier. The barrier is known as lignin.

Scientists Examine the Impact of Increased Carbon Dioxide on Plants

Posted in Climate, Plants, tagged , , on 06/09/2014|

Carbon dioxide is a greenhouse gas that is believed to raise global temperatures. In the past 200 years, carbon dioxide has increased by 35 percent. Scientists are working with natural resource managers to better understand how plants respond to changes in atmospheric carbon dioxide to maximize plant productivity.

The Healthy Grown Label: Healthy Food and Healthy Land

Posted in Plants, tagged , , on 06/09/2014|

Eco-labeling is a new certification program similar to the organic label, but goes beyond the organic concept by reflecting new land management practices for the entire farm ecosystem, including non-crop lands. With funding from USDA’s Cooperative State Research, Education, and Extension Service (CSREES), a team of scientists, growers and environmentalists in Wisconsin developed the “Healthy Grown” label to reflect this land management practice to promote balanced agricultural management and support broad ecosystem health.
