Lower Cost, Second Generation System Meets High Standards of an Environmentally
Superior Technology. Scientists at ARS Florence and industry cooperators demonstrated
at full-scale a second generation treatment system for swine waste that
can achieve high treatment performance of an Environmentally Superior Technology,
yet it is three times more economical than earlier versions.

New Biological Nitrogen Treatment. Scientists at ARS Florence Center isolated a new Anammox bacteria from
animal manure that removes five times more nitrogen that traditional systems.
This finding may led to development of more economical manure treatment
systems. Pilot tests have been completed both in the USA and Brazil.

Recovery of Phosphorus from Solid Manure. A treatment process, called quick wash, was developed for
recovery of P from poultry litter and animal manure solids. Recovered phosphorus
can be used as fertilizer, and washed litter can be recycled as bedding
material or used for bio-energy conversion.

Making the Most of Manure. A team of scientists developed a cost-benefit model of a wet
gasification technology patented by the U.S. Department of Energy(DOE)
to calculate estimated returns, and concluded that liquid swine wastes
can generate a net energy potential comparable to brown coal.

Livestock Air Treatment Using PVA-Coated Powdered Activated Carbon Biofilter. Scientists at ARS Florence found that biofilters using polyvinyl-alcohol-gel
coated powered activated carbon particles (PVA) removed most of ammonia
(80%) and hydrogen sulfide (97%) from livestock air.
Furthermore, the PVA biofilters consumed significantly lower energy than
compost biofilters due to its lower pressure drop requirements. More Information:

Energy and Biofuels from Animal Manure: Wet Gasification. Our collaborative feasibility analysis with the Pacific Northwest
National Laboratory (PNNL) shows that the PNNL wet gasification technology
not only produces methane from animal and municipal wastes, it also provides
many environmental benefits such as destruction of pathogens and PACs,
small foot print requirements, and clean water production. More information: Catylytic Wet Gasification...

Energy and Biofuels from Animal Manure: Obstacles and Opportunities. We have reviewed thermochemical conversion technologies to
be integrated with existing livestock waste management practices and identified
obstacles and opportunities. Even with challenges of cleaning up of product
gas, these waste-to-energy treatment schemes provide significant environmental
improvements resulting in cleaner water and air.
