(FAOICARDA, 2017)
and biomass. Biomass uses biological,
chemical and physical processes to generate liquid
or gaseous biofuels, such as biodiesel, bioethanol
and biogas.
Biogas is a viable and essential form of energy in
agricultural and rural areas, obtained from...

Producción de biogás a través de lactosuero producido por la industria quesera
(Universidad de Chile, 2015)
La producción de biogás a través de lactosuero proveniente de la industria quesera, surge
como una oportunidad de valorización energética de un residuo de la industria láctea
menor que no tiene otra finalidad que la disposición final. Aprovechar el...
The production of biogas through whey from the cheese industry arises as an opportunity for energy recovery from a minor dairy industry residue that has no other purpose than final disposal. Taking advantage of the energy potential that it possesses, through the anaerobic digestion of highly concentrated whey, was the main objective to be developed. For this purpose, a whey degradability test was carried out at three organic loads: AI 25, 50 and 100% vlv. Where each one was independently inoculated with three bacterial populations: one from cow slurry and two from the wastewater treatment plant (PTAS). The inoculum plus whey mixtures were sealed and stored under anaerobic conditions at 35o C for 70 days, measuring the generation of biogas in each of the trials. From the results obtained, it was found that the best biogas generation condition corresponds to the mixture of granular inoculum from PTAS with whey at 25% ovlv. Under these conditions, 3035 mL of biogas were generated in 70 days of incubation and the largest amount of whey was degraded, with a 31.91% decrease with respect to the input Chemical Oxygen Demand. It was possible to maintain a neutral pH of 7.15, which is suitable for the development of methanogenesis. In addition, the test inoculated with this bacterial population managed to generate biogas with a high organic load (100%) allowing to fulfill the main objective of this research...

Analisis de algunas variables fisicoquimicas y biologicas en la produccion de biogas de dos rellenos sanitarios
(Universisdad de Chile, 2010)
La biodegradación de la materia orgánica, contenida, en residuos sólidos domiciliarios, es una variable que incide en la descomposición de la basura del rellena sanitario y por ende, influye en la cantidad y calidad del biogas producido. Por este...
Prefactibilidad técnica - económica de la depuración y utilización del biogás generado en biodegestores anaeróbicos de purines de cerdo

The present study was requested by Agicola Super Ltda. to Poch Ambiental S.A. being lts main objective to propose reasonable utilization options to the biogas produced at the eight anaerobic digesters property ofthe company. A complete rcview ofthe project digesters location and it main operating parameters was done. A bibliographic review on biogas production, cleaning and upgrading the gas, and the main issues conceming its utilization on CHP (combined heat & power) and heating systems involved in swine production was realized. The biogas was chemically analyzed under gas chromatography and it was determined as usable containing a methane %u between 55 70 Vo fot the eight anaerobic digesters. The energetic requirements (consumed electrici§ and propane) on the project zone were determined in order to visualize rvhich fraction of the requirements could be covered with the use ofthe biogas. It is statcd that 20olo of the installed electric porver on the project location could be covered in case of utilizing all the biogas produced for this purpose; on the other hand 100% of the heating rcquirements for the evaluated bams of the company could be covered Scvcral options l,ere analyzed lor biogas utilization, remarking CIIP and heating systems based on hot water biogas boilcrs. Both technologics can work rvith raw biogas. The selected utilization equipment and everything else needed to implement the project was quoted as a budgetary price. With this information economic evaluations were made up obtaining positive economic indicators revealiog that the proposed project is feasible in technical and economical terms. The project contributes to sustainable development by using biogas, a renewable energy, which displaces the actual utilization of fossil fue1s used to generate electricity and heat....

Selecting and characterizing bacterial consortia with the potential of fixing CO2 and removing H2S in a biogas atmosphere
(Kluwer Academic Publishers, 2014)
Biogas must be pretreated before its use; thus, both physical and chemical methods have been implemented to remove the fuel's principal pollutants (CO 2and H2S). Additional removal methods that use microorganisms' biological processes to eliminate...
Guía para el diseño de sistemas de recuperación de biogás en rellenos sanitarios
(Universidad de ChileCyberDocs, 2009)
Uno de los procesos más importantes que se llevan a cabo dentro de un relleno sanitario es la degradación anaeróbica de los residuos sólidos urbanos, produciéndose una serie de gases llamados en conjunto biogás. El gas metano es uno de sus...
