“…Os materiais lignocelulósicos são uma fonte promissora de energia renovável, pois podem ser convertidos em biocombustíveis por meio de caminhos bioquímicos ou termoquímicos. O resíduos deixado no campo após a colheita do milho incluem palha, colmo e folhas, estes se destacando bastante devido a sua alta disponibilidade e taxa de produção (Karimi Alavijeh & Karimi, 2019;Qin et al, 2017). Aproximadamente 51,28% das biorrefinarias celulósicas operacionais, planejadas e em construção, são alimentadas com resíduos oriundos do cultivo de milho.…”

O consumo de combustíveis tem sido muito elevado durante as últimas décadas, como consequência ocasionou-se um grave problema ambiental: o efeito estufa. Vários estudos estão sendo realizados a fim de se encontrar soluções. Outra grande adversidade está na grande quantidade de resíduos gerados na agricultura, cuja disposição final em boa parte não é sustentável tampouco lucrativa. O milho está entre os cereais mais produzidos no planeta, gerando uma quantidade ainda maior de resíduos. A cada tonelada de grão de milho coletado são produzidos cerca 1,4 toneladas de resíduos. Só no Brasil são mais de 100 milhões de tonelada por ano. Neste trabalho, os resíduos da cadeia produtiva do milho, sendo esses a folha, a palha e o colmo, foram utilizados após três anos em estoque para realizar a caracterização in natura. Foi realizada uma pré-secagem para análises posterior. As biomassas ficaram em estoque durante três anos. Após o período foram efetuadas a gaseificação, processo esse de conversão de biomassa em gás com propriedades combustíveis, syngas, utilizando diferentes parâmetros de temperatura (700 °C, 800 °C, 900 °C) e tempo de residência (três, quatro e cinco minutos). Nos gases combustíveis produzidos foram analisados suas características individuais além de sua efetividade energética. O poder calorífico inferior do colmo, folha e palha são respectivamente 16,39 MJ.kg-1, 16,01 MJ.kg-1e 16,40 MJ.kg-1. Os maiores valores do poder calorífico inferior dos gases obtidos na análise do colmo, folha e palha foram respectivamente 4,99 MJ. Nm-3, 6,62 MJ.Nm-3, 4,97 MJ.Nm-3.

“…A large amount of collectible residues can be provided in the mid-West of the United States. It is estimated that the amount of biobutanol that can potentially be produced from corn residue is equivalent to 11.8% of its total domestic gasoline consumption [14]. Some scholars have also studied the optimization of biofuel production from both economic and environmental aspects and found that the bioethanol production from corn straw has the lowest cost and the least carbon emissions [15].…”

In recent years, the unsustainable behaviors of straw utilization have led to waste straw being one of the sources of agricultural non-point source pollution. Studying the resource utilization of crop straw is conducive to expediate the development of ecological and green agriculture. More importantly, it has long-term significance for the recycling of agricultural waste, improving the quality of rural life, and the employment of farmers. Based on the theory of planned behavior (TPB), taking the representative survey questionnaire of farmers in Jilin Province, China as the sample, the structural equation model (SEM) was constructed to study the main factors that drive the utilization behaviors of straw resources of farmers and to explore the driving mechanism of the farmers behaviors in Jilin Province. The results show that the behavioral attitude and subjective norms of farmers in Jilin Province not only indirectly affect their actual behaviors through behavioral willingness, but also has significant direct effects on their behaviors. The most critical factors that affect the willingness of farmers to utilize the straw resources in Jilin Province are subjective norms and moral responsibilities. The subjective norms of farmers have a direct and significant positive impact on their willingness and behaviors. Behavioral attitude and perceived behavior control have a significant positive impact on their willingness. The behavioral willingness has a significant positive impact on their actual behaviors. This study provides guidance for the utilization of straw resources policy implications.

“…Besides, the escalation of carbon dioxide levels and GHG emissions have renewed interest in adopting alternative energy resources. 1 Biomass could be one of the most promising sources of renewable energy that can be converted to biofuels via thermochemical and/or biochemical routes. 2 Among different available biofuels, biobutanol has outstanding benefits to be used along with gasoline in the automotive market.…”

In the present study, the effect of one of the most important lignin-derived inhibitors (lignosulfonate) was assessed. A technique to overcome the lignosulfonate inhibitory action in the acetone-butanol-ethanol (ABE) fermentation process is proposed here. Different lignosulfonates were primarily added in the fermentation medium to observe their mechanistic action on the ABE production profile. Augmenting lignosulfonate concentration (>0.5 g L −1 ) resulted in a drastically reduced solvent titer (ABE ∼1.50 g L −1 ). Especially, low-molecularweight lignosulfonate (>1 g L −1 ) severely affected the solvent production and completely ceased the fermentation process. Therefore, a strategic approach that triggers the key genes responsible for butanol production was explored. The experimental analysis revealed that soy meal addition could enhance Clostridium acetobutylicum survival in the presence of lignosulfonates (0.25-3 g L −1 ). Moreover, soy meal addition also enhanced butanol concentration over 1.5-fold as compared to the control experiment. The ABE production using wood hydrolysate also produced substantial solvent titer (ABE ∼11 g L −1 ) in the presence of soy meal (5 g L −1 ). The transcriptional analysis results showed that important genes in clostridial metabolic pathways were up-regulated in the presence of soy meal addition during fermentation.
