“…In Texas, DM losses during large, round baling ranged from 1 to 5%, with larger losses occurring with drier material. 35 Switchgrass bales stored for 6 or 12 months inside had 0 to 2% DM losses, whereas bales stored outside lost 5 to 13% of the original bale weight. 35 Switchgrass bales stored unprotected outside lost up to 11% of ethanol extractables, which could signifi cantly reduce conversion to ethanol.…”

The United States Department of Energy (DOE) has identifi ed switchgrass (Panicum virgatum L.) as a viable perennial herbaceous feedstock for cellulosic ethanol production. Although switchgrass bioenergy research was initiated by USDA-ARS, Lincoln, NE, USA in 1990, switchgrass research has been conducted at this location since the 1930s. Consequently, a signifi cant amount of genetic and agronomic research on switchgrass has been conducted for the Corn Belt and Central Great Plains of the USA that is directly applicable to its use as a biomass energy crop. Similar research must be conducted in other major agroecoregions to verify or modify switchgrass management practices (agronomics) for bioenergy production. The technology to utilize switchgrass for producing ethanol using a cellulosic platform or by pyrolysis to generate syngas is advancing rapidly. Regardless of platform, using switchgrass for ethanol production will require the development of improved bioenergy cultivars or hybrids and improved agronomics to optimize production and will introduce competing uses for the land base.

“…These storage options are often more expensive than outdoor storage, however conservation can be excellent with losses of 1-3% of DM if initial moisture is less than 20% (w.b.) [28,60,66]. Round bales shed precipitation and so lowcost outdoor storage is possible, although losses will be 2-15% of DM depending upon precipitation amount, length of storage, type of bale wrap, and ground preparation [28,60,66].…”

Alternatives such as wrapping with breathable-film or stretch-film that allow round bales to be stored outdoors with exposure to precipitation are being explored as part of this research.…”

Sustainability Protocols and Certification Criteria for Switchgrass-Based Bioenergy

Production of bioenergy from cellulosic sources is likely to increase due to mandates, tax incentives, and subsidies. However, unchecked growth in the bioenergy industry has the potential to adversely influence land use, biodiversity, greenhouse gas (GHG) emissions, and water resources. It may have unintended environmental and socioeconomic consequences. Against this backdrop, it is important to develop standards and protocols that ensure sustainable bioenergy production, promote the benefits of biofuels, and avoid or minimize potential adverse outcomes. This paper highlights agronomic information on switchgrass, a high-potential bioenergy feedstock, and the role of specialized certification programs. The existing sustainability standards and protocols were reviewed in order to identify key gaps that justify a certification program specifically for switchgrass-based bioenergy. The criteria and indicators that should be considered for such a certification program are outlined.
