“…After a 24-hour incubation, gas pressure and gas composition (in terms of CO2, CH4, NH3) were recorded by an ABE_1500 (A.B.Energy Srl, Cossato, Italy) infrared portable gas analyzer, currently used by a renewable energy power plant [13][14][15][16][17]. As well as the energy production plant monitoring, the infrared method for gas analyses was also used in previous lab scale experiments, which provided the evaluation of methane concentration due to rumen emissions [18,19].…”

Abstract:The effects of increasing concentrations of oregano (Origanum vulgare L.) and rosemary (Rosmarinus officinalis L.) essentials oil (EO) on ruminal gas emissions were tested in vitro using 50 mL serum bottles. Each bottle contained a 200 mg substrate (alfalfa hay and corn meal 1:1) and a 20 mL solution composed of a buffered medium and rumen fluid (1:2). The percentage of ruminal fermentation products was quantified by an infrared analyzer. The reduction of total gas production was 6% and 9% respectively when using the 1.5 and 2.0 g/L oregano EO measurements. The reduction of methane production was 55%, 72% and 71% respectively with regard to the 1.0, 1.5 and 2.0 g/L oregano EO doses, while rosemary EO (2.0 g/L) reduced the methane production by 9%. The production of ammonia was significantly reduced (59%-78%) by all treatments with the exception of OPEN ACCESSSustainability 2015, 7 12857 rosemary EO at the lowest dose. Dry matter and neutral detergent fiber degradability was reduced by most of the treatments (respectively 4%-9% and 8%-24%). The total volatile fatty acids (VFA) concentration was markedly decreased by oregano EO and was not affected by rosemary EO. Both EOs mitigated rumen fermentations, but oregano EO gave rise to the highest reduction in methane and ammonia production. However, further research is needed to evaluate the use of these essential oils as dietary supplements by taking into account the negative effects on feed degradability.

“…An ORC was chosen over a cheaper internal combustion engine due to the latter being inefficient as it converts only one-third of the fuel energy into mechanical work whereas the former is an efficient means of recovering heat [14]. Other reasons are the ORCs relatively quiet operation, small size, no emissions of exhaust gases (CO, CO 2 , NO x ) and other atmospheric pollutants and no need for severe and problematic gas cleaning process which ICEs require [15].…”

“…The first hypothesis concerns the evaluation of the carbon dioxide for a biomass fed plant instead of natural gas: in this case, we have applied an increased coefficient to the CO 2 flux for natural gas that is equal to 1.30. This evaluation arises from past studies carried out by the Italian CRB and also previous literature [25,26]. The second hypothesis concerns the evaluation of the CO 2 flux purity resulting from the CHP plant: in the case of natural gas feeding, the outgoing CO 2 flux is almost pure while in the case of lignocellulosic biomass feeding, the outgoing CO 2 flux needs to be purified by means of separation technologies.…”

This work presents some energy considerations concerning a biorefinery case study that has been carried out by the CRB/CIRIAF of the University of Perugia. The biorefinery is the case study of the BIT3G project, a national funded research project, and it uses the lignocellulosic biomass that is available in the territory as input materials for biochemical purposes, such as cardoon and carthamus. The whole plant is composed of several sections: the cardoon and carthamus seed milling, the oil refinement facilities, and the production section of some high quality biochemicals, i.e., bio-oils and fatty acids. The main goal of the research is to demonstrate energy autonomy of the latter section of the biorefinery, while only recovering energy from the residues resulting from the collection of the biomass. To this aim, this work presents the quantification of the energy requirements to be supplied to the considered biorefinery section, the mass flow, and the energy and chemical characterization of the biomass. Afterwards, some sustainability strategies have been qualitatively investigated in order to identify the best one to be used in this case study; the combined heat and power (CHP) technology. Two scenarios have been defined and presented: the first with 6 MWt thermal input and 1.2 MWe electrical power as an output and the second with 9 MWt thermal input and 1.8 MWe electrical power as an output. The first scenario showed that 11,000 tons of residual biomass could ensure the annual production of about 34,000 MWht, equal to about the 72% of the requirements, and about 9600 MWhe, equal to approximately 60% of the electricity demand. The second scenario showed that 18,000 tons of the residual biomass could ensure the total annual production of about 56,000 MWht, corresponding to more than 100% of the requirements, and about 14,400 MWhe, equal to approximately 90% of the electricity demand. In addition, the CO 2 emissions from the energy valorization section have been quantified and the possibility of re-using the CO 2 flow in order to produce methane is described.
