“…In their Table 4 they report an extremely high total cost of $100 Mg −1 , attributed to an unpublished study that is no longer available at the cited URL. Another recent study [15], based on a 4-year field-scale (8.6 ha) study in northern Italy, reported average yield at 6 Mg ha −1 for the last 3 years, annualized cost at about ∈120 Mg −1 (approximately $150 Mg −1 .) To the authors' knowledge, this is the only other published study of recorded costs on field scale switchgrass production, though it is not very relevant to cost of production in the USA.…”

Farm-Scale Production Cost of Switchgrass for Biomass

et al. 2008

The economic potential of cellulosic biomass from switchgrass has heretofore been evaluated using estimates of farm costs based on extrapolation from experimental data and budget estimates. The objective of the project reported here was to estimate the cost of production that would be experienced by farmers on commercial production situations. Switchgrass was produced as a biomass crop on commercial-scale fields by ten contracting farmers located from northern North Dakota to southern Nebraska. Results showed a wide range of yields and costs across the five production years and ten sites, with an overall average cost of $65.86 Mg −1 of biomass dry matter, and annualized yield of 5.0 Mg ha −1 . The lowcost half of the producers were able to produce at an average cost of $51.95 Mg −1 over the 5-year period. When projected to a full 10-year rotation, their cost fell further to $46.26 Mg −1 . We conclude that substantial quantities of biomass feedstock could have been produced in this region at a cost of about $50 Mg −1 at the farm gate, which translates to about $0.13/l of ethanol. These results provide a more reliable benchmark for current commercial production costs as compared to other estimates, which range from $25 to $100 Mg −1 .

“…Varela et al (1999) and Miranda and Hale (2001) have assessed the full social costs of biomass and other energy options. Monti et al (2007) found that switchgrass production in Italy may be viable at the high market prices that may be expected over the next few years. Biomass and the associated production of renewable energy and complimentary products (oil, activated carbon) provides an important economic incentive to offset the opportunity costs of foregone agricultural production and to encourage large-scale tree plantings (Walsh et al, 2003;Updegraff et al, 2004).…”

Nitrogênio e idade de corte na qualidade da biomassa de capimelefante para fins agroenergéticos cultivado em Latossolo

ResumoAtualmente um dos grandes desafios para a pesquisa de agroenergia é a produção de material energético alternativo derivado da biomassa vegetal. Aliado a isso, o manejo adequado do nitrogênio, torna-se fundamental para obter ganhos de produtividade e melhoria na qualidade da biomassa de capim-elefante. Desse modo, objetivou-se avaliar o efeito da adubação nitrogenada e da idade de corte do capimelefante (Pennisetum purpureum) na qualidade da biomassa da forrageira para fins agroenergéticos. O experimento foi realizado com o genótipo Paraíso, cultivado em um Latossolo Vermelho Amarelo distrófico no sul do Estado de Tocantins. O delineamento experimental foi de blocos casualizados com parcelas subdivididas, localizando-se nas parcelas as doses de nitrogênio (0, 50, 100 e 150 kg ha -1 ) e nas subparcelas a idade de corte (120, 150 e 180 dias após o plantio), quatro repetições. Avaliaram-se as relações carbono:nitrogênio (C:N) e colmo:folha (C:F), teores de fibras em detergente neutro (FDN) e os teores de cinzas produzidas na biomassa seca. A aplicação de nitrogênio incrementou em 12% a relação C:N da planta. A maior idade de corte da forrageira incrementou-se em 9% a relação C:N da planta, entretanto, diminuiu em 12 e 14% os teores de cinzas produzidas no colmo e nas folhas, respectivamente. A produção de capim-elefante para fins agroenergéticos é viável com o sistema de manejo proposto, pois apresentou características qualitativas desejáveis, como alta relação C:N, acima de 40 e altos teores de fibras, acima de 50%. Palavras-chave: Pennisetum purpureum, adubação nitrogenada, bioenergia AbstractNowadays one of the major challenge for research is the production of alternative agrifuels energy material derived from plant biomass. Allied to this, the proper management of nitrogen, becomes fundamental for productivity gains and improvement in quality of elephant grass biomass. Thus, the objective was to evaluate the effect of nitrogen fertilization and plant age effect on the quality of elephant grass biomass for energy purposes. The experiment was performed with genotype Paraíso, grown in a dystrophic Oxisol in the southern state of Tocantins. The design was randomized blocks with subdivided plots, situating plots as nitrogen rates (0, 50, 100 and 150 kg ha -1 ) and the subplots cutting age (120, 150 and 180 days after planting ) four replicates. We evaluated the relationship carbon/nitrogen (C:N) and
