Bioenergy And Carbon Farming Opportunities In The Pilbara, Robert Sudmeyer, Kim Brooksbank, David Rogers

Bulletins 4000 -

The Pilbara region covers 270 000 square kilometres of north-west Western Australia. Its main agricultural land use is pastoralism, with beef cattle grazing native pastures. Currently, only 24km² is under irrigation, with irrigated fodder the principal crop, but this could expand to 100km². This expansion has the potential to significantly broaden the economic base of the Pilbara.

Irrigation and the opportunities for changing land use and management may facilitate greater participation in the carbon economy by Pilbara land managers. Bioenergy feedstocks could be sourced from purpose-grown crops or agricultural wastes. Carbon farming activities may be facilitated by …

Carbon Abatement And Emissions Associated With The Gasification Of Walnut Shells For Bioenergy And Biochar Production, Engil Isadora Pujol Pereira, Emma C. Suddick, Johan Six

School of Earth, Environmental, and Marine Sciences Faculty Publications and Presentations

By converting biomass residue to biochar, we could generate power cleanly and sequester carbon resulting in overall greenhouse gas emissions (GHG) savings when compared to typical fossil fuel usage and waste disposal. We estimated the carbon dioxide (CO2) abatements and emissions associated to the concurrent production of bioenergy and biochar through biomass gasification in an organic walnut farm and processing facility in California, USA. We accounted for (i) avoided-CO2 emissions from displaced grid electricity by bioenergy; (ii) CO2 emissions from farm machinery used for soil amendment of biochar; (iii) CO2 sequestered in the soil through stable biochar-C; and (iv) direct …

Dedicated Energy Crops And Crop Residues For Bioenergy Feedstocks In The Central And Eastern Usa, R. B. Mitchell, M. R. Schmer, W. F. Anderson, V. Jin, K. S. Balkcom, J. Kiniry, A. Coffin, P. White

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Dedicated energy crops and crop residues will meet herbaceous feedstock demands for the new bioeconomy in the Central and Eastern USA. Perennial warm-season grasses and corn stover are well-suited to the eastern half of the USA and provide opportunities for expanding agricultural operations in the region. A suite of warm-season grasses and associated management practices have been developed by researchers from the Agricultural Research Service of the US Department of Agriculture (USDA) and collaborators associated with USDA Regional Biomass Research Centers. Second generation biofuel feedstocks provide an opportunity to increase the production of transportation fuels from recently fixed plant carbon …
