There is some research suggesting that separating swine manure into solids and liquids can slightly reduce greenhouse gas (GHG) emissions emitted from the manure itself. It is not likely to be significant enough for separation to be a viable strategy by itself.
The primary reason to use solid-liquid manure separation is to prepare manure for further treatment in a system that can:
The materials on this page are an interactive lab designed to introduce students (high school level) to pig farming and the connections between management decisions and the greenhouse gas emissions. It also includes information on the economic implications of those decisions. Background information and activities are provided in a graphical (visual) format.…

The research and modeling work encompassed by this project offers great potential for assisting researchers, policy makers, and especially farm managers to make informed management and facilities decisions regarding GHG emissions while maintaining production and profitability.…

Algal biomass offers many advantages over traditional energy crops; algal biomass generates higher yields and requires smaller land area than other energy crops. In addition to biomass production for potential biofuel feedstock generation, algal growth systems can also act as tertiary treatment systems for wastewater.…
Many, if not most, systems designed for manure treatment depend on reliable solid-liquid separation. What is solid-liquid separation for manure and when is it something to consider doing for your farm?
Manure can be thought of as a mixture of water, minerals, and organic components.…
This webcast features a developer who has worked extensively with university extension as well as many other clients in sports, journalism, and agriculture. Two manure management apps are demonstrated followed by a panel discussion that features more manure-related apps and discusses challenges, opportunities and lessons learned when creating those apps.…
The topics for this webcast include: pile characteristics for effective composting, management and environmental considerations when siting and managing composting facilities; mortality compost nutrients for on-farm use; and teaching the benefits of mortality composting to producers. This presentation was originally broadcast on August 15, 2014.…
