Journal ArticleDOI
Impact of pyrolysis temperature and manure source on physicochemical characteristics of biochar.
TL;DR: Select physicochemical results for five manure-based biochars pyrolyzed at 350 and 700°C are reported: swine separated-solids; paved-feedlot manure; dairy manure; poultry litter; and turkey litter.
Journal ArticleDOI
Biochar: a synthesis of its agronomic impact beyond carbon sequestration.

TL;DR: Hardwood biochar (black carbon) produced by traditional methods (kilns or soil pits) possessed the most consistent yield increases when added to soils, and the universality of this conclusion requires further evaluation due to the highly skewed feedstock preferences within existing studies.
Journal ArticleDOI
Livestock waste-to-bioenergy generation opportunities
TL;DR: Integration of biological and thermal-based conversion technologies in a farm-scale hybrid design by combining an algal CO2-fixation treatment requiring less than 27,000m2 of treatment area with the energy recovery component of wet gasification can drastically reduce CO2 emissions and efficiently recycle nutrients.
Journal ArticleDOI
Qualitative analysis of volatile organic compounds on biochar.

TL;DR: In this paper, the authors used headspace thermal desorption coupled with capillary gas chromatographic mass spectrometry to identify sorbed volatile organic compounds (VOCs) on biochar.
Journal ArticleDOI
High-Temperature Pyrolysis of Blended Animal Manures for Producing Renewable Energy and Value-Added Biochar
TL;DR: In this paper, a commercial pilot-scale pyrolysis reactor system was used to produce combustible gas and biochar at 620 °C from three sources (chicken litter, swine solids, mixture of swine subsides with rye grass).
