Resource use efficiency of rice production upon single cropping and ratooning agro-systems in terms of bioethanol feedstock production

The main aim of this paper was to investigate factors affecting the adoption of pressurized irrigation technology among Roudbar County olive farmers by path-structural modeling and Unified Theory of Acceptance and Use of Technology. Data were collected through an information technology questionnaire addressing a cross section of 210 managers of olive farms (4.18% of the statistical population) in the Roudbar County, Northern Iran. Validity of the questionnaire was proofed using several tests (content, face, convergent and discriminant). Likewise, reliability of the questionnaire was tested employing principal component analysis, Cronbach's alpha, Dillon-Goldstein's ʃ and reagent stability. Descriptive and inferential statistical analysis of the data was accomplished using SPSS V19 and SmartPLS V3 software. For testing hypotheses, structural equation model and partial least squares that focus on reagent variance were used. Results show a significant relationship between: (a) performance expectancy and behavioral intention, (b) social influence and behavioral intention, (c) facilitating conditions and use behavior. A significant relationship was also observed between intention to use and use behavior of pressurized irrigation technology. The employed model explains 72% of behavioral intention variance and 42% of use behavior of pressurized irrigation technology variance among olive farmers. To increase willingness to accept technology among Roudbar County olive farmers, it is suggested to hold extension and education courses by organizations for raising knowledge and awareness of pressurized irrigation technology. Also, olive farmers can be provided with financial resources and knowledge to enable them to adopt this new irrigation technology.

“…Compared to petroleum, carbon loss from the conversion of biomass into biofuels/chemicals is higher due to the thermodynamic inefficiency caused by the additional unit operations required to change its phase, such as from biomass to liquid or biomass to gas . It should also be noted that representative biofuels, such as bioethanol or biodiesel, are only produced from specific components in biomass, , which are the sugar-based compounds (namely, cellulose) and lipids, respectively. The fermentation process has been known as an energy efficient process, however, unwanted carbon loss by microbial respiration and growth is inevitable, as it is challenging to manipulate microbial metabolism .…”

As global warming and climate change become perceived as significant, the release of greenhouse gases (GHGs) stored in the earth’s polar regions is considered a matter of concern. Here, we focused on exploiting GHGs to address potential global warming challenges in the north polar regions. In particular, we used CO2 as a soft oxidant to recover energy as syngas (CO and H2) and to produce biochars from pyrolysis of peat moss. CO2 expedited homogeneous reaction with volatile matters from peat moss pyrolysis, and the mechanistic CO2 role resulted in the conversion of CO2 and peat moss to CO at ≥530 °C. Steel slag waste was then used as an ex situ catalyst to increase reaction kinetics, addressing the issue of the role of CO2 being limited to ≥530 °C, with the result where substantial H2 and CO formation was achieved at a milder temperature. The porosity of biochars, a solid peat moss pyrolysis product, was modified in the presence of CO2, with a significant improvement in CO2 adsorption capacity compared to those achieved by N2 pyrolysis. Therefore, CO2 has the potential to serve as an initial feedstock in sustainable biomass-to-energy applications and biochar production, mitigating atmospheric carbon concentrations.

“…Agriculture is an energy-intensive sector (Hassapoyannes and Blandford, 2019;Firouzi et al, 2018;Gökdoğan et al, 2019), and the food processing industry is one of the highest consumers of energy in the manufacturing sector (Compton et al, 2018). Overall, the food sector consumes globally about 200 EJ per year (Bakalis et al, 2019).…”

Energy auditing, modeling and optimization are the important tools which can be considered toward achieving a sustainable food supply chain (FSC). In this regard, energy modeling and optimization have become a hot topic in the food sector and thus, several mathematical and computational intelligent-based systems have been applied to model and optimize the energy flows of FSC. This study briefly reviewed the widely used mathematical (multiple linear regressions, data envelopment analysis) and computational intelligent-based (artificial neural networks, adaptive neuro fuzzy inference systems, genetic algorithm) approaches for modeling and optimization of the energy flow in FSC. Based on the literature review it can be inferred that computational intelligent based approaches could better model and optimize the energy flows than mathematical approaches and the performance of computational intelligent-based systems showed that this approach can be generally applicable for modeling and optimizing energy flows of FSC.
