Connecting agri-professionals advancing environmental stewardship in animal agriculture
Fixed Bed types produce low Btu gases and can use updraft or downdraft approaches. The updraft pulls hot air up from the bottom through the fuel where pyrolysis (decomposition of organics by heat in the absence of oxygen) occurs first, followed by reduction and oxidation.…
When looking at ways to improve the environmental impact of pig production, renewable energy generation is a popular topic. One such technology, gasification, is a series of chemical reactions (see image at bottom) that involve heating a suitable organic material in a controlled, low-oxygen environment to the point that the hydrocarbons (simple organic compounds that contain only hydrogen and carbon) are converted to synthesis gas (‘syngas’).…
From 2012-2015, the Farm Manure-to-Energy Initiative conducted a study of thermal, farm-scale systems that produce energy from poultry litter. The technologies were installed on working farms in the Chesapeake region, in places where manure management is especially important for protecting water quality.…
Livestock operations continue to expand and concentrate in certain parts of the country. This has created regional “hot spot” areas in which excess nutrients, particularly phosphorus, are produced. This nutrient issue has resulted in water quality concerns across the country and even lead to the necessity of a “watershed diet” for the Chesapeake Bay Watershed.…
The Technology
The Ecoremedy gasifier ® by Enginuity Energy was installed on Flintrock Farm in Lancaster County, PA, in 2014 as a demonstration project for the Farm Manure-to-Energy Initiative.
The gasifier is a fixed feed rate, chain-grate, air-blown system that uses poultry litter as a fuel.…
Using manure to generate energy is growing in popularity. Explore the topics below to learn more.
There are two general methods for producing energy from manure: the use of heat and the use of bacteria. This page is focused on the use of heat – specifically, on relatively small thermal systems that can be used on a farm to produce energy from excess poultry litter or manure.…
Technologies to treat animal manure are rapidly gaining more traction as producers search for ways to minimize environmental impact and maintain a profitable operation. In the conclusion of this 2-part webcast, the focus continues on a thermal technology, pyrolysis, and the resulting biochar.…

Continued advances in technology have facilitated new avenues to access and extract energy (in various forms) from materials such as animal manure and crop residues that have not traditionally been considered viable fuel sources. This presentation discusses the use of thermochemical processes, including gasification, to produce biofuels from animal manure and was originally broadcast on February 28, 2014.…
