The University of Idaho (UI) and the Idaho Sustainable Agriculture Initiative for Dairy (ISAID) will host a national Waste to Worth Conference April 7-11, 2025, in Boise, Ida., focused on finding creative and valuable ways to make use of animal waste.
The Livestock & Poultry Environmental Learning Community (LPELC), a network of professionals from the U.S. and Canada involved in animal agriculture and environmental stewardship, hosts the conference every few years in a different region.
Assistant professor Linda Schott, a UI Extension specialist of nutrient and waste management, and professor Mario de Haro-Martí, UI Extension educator based in Gooding County specializing in agricultural nutrient and waste management, are co-chairing the 2025 conference, along with professor Rhonda Miller, Utah State University agricultural environmental quality Extension specialist.
ISAID is funded with a $10 million grant from the U.S. Department of Agriculture’s National Institute of Food & Agriculture and involves 78 U I faculty, Extension educators and students, with the goal of converting excess nutrients from dairy production into valuable bioproducts such as commercial fertilizers and bioplastics.
The conference encompasses all aspects of animal agriculture, including management of swine, poultry and cattle feedlot waste. It represents an opportunity to showcase the diversity of Idaho agriculture and the scope of the state’s dairy industry. Idaho is the nation’s third-largest dairy-producing state, and the dairy industry will be emphasized at the forthcoming conference.
“Idaho is a really unique location and climate for dairy production, which is different from other dairy states in the U.S.,” Schott said. “The sizes of our dairies are large, and they’re irrigated, which is a different production system. We also have small agricultural producers and lots of diversity in Idaho agriculture in general that folks coming in from other parts of the country may never have experienced before.”
Schott believes attendees from other states will benefit by learning about Idaho’s unique approach to dairy production. In turn, Idaho participants will glean fresh ideas through their interactions with participants from other states facing different challenges.
“By hosting folks from elsewhere, we can hear feedback of, ‘Oh, we did this in Wisconsin, or we did this in Texas or New York,’ and get the ball rolling for collaboration,” Schott said.
On the night of April 9, faculty, graduate students and undergraduates will present about 40 posters featuring relevant research. Every student involved in ISAID will present a poster. Student researchers will be eligible to win cash prizes for their presentations.
Michael Parrella, J.R. Simplot Endowed Dean of the UI College of Agricultural and Life Sciences, will speak during the conference about the university’s forthcoming Idaho Center for Agriculture, Food & the Environment, which will include the nation’s largest research dairy in Rupert, Ida.
Mark McGuire, a University Distinguished Professor in the Department of Animal, Veterinary and Food Sciences who leads the ISAID grant, will discuss accomplishments of the ISAID research team.
Other speakers will address water issues and the rise of the bio-circular economy that involves converting waste into useful products.
A panel of industry officials will discuss the increasing emphasis on sustainability, and a panel of producers will address how they’re approaching increasing demands to incorporate sustainability practices into their production.
The conference will include three tours highlighting Idaho agriculture on April 8. One will visit dairies spanning from Boise through the Magic Valley. A second tour of the Treasure Valley will highlight water and wastewater management, both from urban and agricultural land. A third tour will visit Lucky Peak Dam, emphasizing how irrigation water is supplied in the Treasure Valley, and will also make stops at small agricultural operations to highlight how they’re upcycling manure, as well as the diversity of Idaho cropping rotations.
The Waste to Worth Conference will be hosted at The Grove Hotel in Boise, with registration available online. Organizers expect 100-150 participants representing Cooperative Extension, other research entities, producers, regulators, conservation groups and industry to attend.
ISAID responds to the critical challenges posed by the growth of Idaho's dairy industry. As the third-largest dairy state, managing the increased volumes of liquid and solid manure presents significant hurdles for Idaho. The ISAID grant aims to convert nitrogen and phosphorus from dairy production into valuable bioproducts, with the ultimate goal of creating a dairy bioeconomy that enhances soil health, sustains agricultural productivity, minimizes environmental impacts and fosters economic opportunities, according to the initiative’s website.
The LPELC network offers participating faculty and staff opportunities to network, collaborate, mentor and share their expertise ranging from research and technical knowledge to application of science on the farm. What used to be done by walking down the hall, now can be done in “virtual” settings. It is our way of trying to do more with less. The network was officially established in 2005 with a USDA National Facilitation grant focused on water quality and has continued through the support of other grants related to air quality, beginning farmers and climate change, among others.
