1. ECONOMIC MANAGEMENT MODEL OF ELECTRICITY GENERATED FROM BIOMASS IN A PIG FARM
ABSTRACT Faced with the increasing demand for renewable energy, researchers have developed several ways to generate them, such as biogas. Thus, the present study aims to demonstrate the economic viability of electricity generation from biodigesters in a pig farm to contribute to sustainable development by reducing pollution in the environment. Studies focuse

2. Biogas and Biomass Implementation in Rural Areas
Abstract Advances in energy demand in rural areas cannot be dissociated from agricultural modernization, large estates, mechanization of labor and reduced investment in small production. The use of biogas together with biomass are the most cost-effective ways for the small producer, as it has a high calorific value. In the case of biogas the procedure is pe

3. Storage of purified biogas (biomethane) at low pressure
ABSTRACT The global use of fossil energy sources has led to the need to develop technologies capable of mitigating its consequences. One such option is anaerobic biodigestion, which is already scientifically well-established, although the use of its main products (biogas and biomethane) still requires further development before they can be employed in automo

4. BIOGAS PRODUCTION IN DAIRY CATTLE SYSTEMS, USING BATCH DIGESTERS WITH AND WITHOUT SOLIDS SEPARATION IN THE SUBSTRATES
ABSTRACT This research aimed to evaluate the biogas production during the anaerobic biodigestion process of dairy cattle manure, with and without solids separation. Sixteen biodigesters of the batch type were used, each one with 2L of capacity, supplied with manure in four different conditions: (1) pure manure, after washing the floors of the free stall syst

5. Química Sem Fronteiras: o desafio da energia
Coal, natural gas and petroleum-based liquid fuels are still the most widely used energy sources in modern society. The current scenario contrasts with the foreseen shortage of petroleum that was spread out in the beginning of the XXI century, when the concept of "energy security" emerged as an urgent agenda to ensure a good balance between energy supply and

6. Tratamento de Ãgua residuÃria de fecularia em reator anaerÃbio com leito fixo de pedras de calcÃrio dolomÃtico / Starch wastewater treatment in anaerobic reactor containing Dolomitic limestone
The cassava processing for starch or flour production generates some wastewater (manipueira) with high organic load and toxic compounds, which cause environmental degradation. In the western Paranà region, there are several starch factories, so its waste generation is a concern for the correct treatment and disposal. Thus, anaerobic reactors are a cost-effe

7. MODELO PARA A ANÁLISE ECONÔMICA E FINANCEIRA EM PROJETOS PARA GERAÇÃO DISTRIBUÍDA DE ENERGIA COM FONTES ALTERNATIVAS / MODEL FOR THE ECONOMIC AND FINANCIAL ANALYSIS OF DISTRIBUTED ENERGY GENERATION PROJECTS WITH ALTERNATIVE SOURCES
The implementation of distributed generation (DG) offers many benefits to the society, the electrical sector where they operate, and the consumers connected to the network especially due to their electricity self-production. For this case, proponents normally fight against costs estimation problems in projects of DG. In this way, low-cost and quality pre-fea

8. Avaliação da co-disposição do lodo de tanques sépticos e fração orgânica de resíduos sólidos domiciliares em reatores anaeróbios / Evaluation of co-disposal of sludge from septic tanks and organic fraction of domestic solid waste in anaerobic reactors
Despite being an emerging country, unfortunately the sanitary situation of Brazil is quite precarious. Only 52.2% of the 5,507 brazilian municipalities have some type of sanitary service (IBGE, 2000). In this alarming scenario, individual solutions are gaining more importance. The adoption of septic tanks as an alternative to the solution of the sewage becom

9. Efeito de antibióticos utilizados em suinocultura sobre a digestão anaeróbia de efluentes / Effect of antibiotics utilized in swine culture on the anaerobic digestion of effluents
The anaerobic systems for wastewater treatment are viable for several reasons, such as low cost and energy use of the biogas generated. However, the anaerobic digestion process is not yet completely understood, mainly due to the lack of knowledge about the toxicity of the anaerobic microbiota present in the sludge with respect to several compounds. In the ca

10. Viabilidade do uso do biogÃs da bovinocultura e suinocultura para geraÃÃo de energia elÃtrica e irrigaÃÃo em propriedades rurais / The viability of using Biogas from bovine culture and swine culture to the generation of electric power and irrigation for rural proprieties
O presente trabalho teve por objetivo avaliar a viabilidade do uso do biogÃs proveniente das atividades de bovinocultura de leite e suinocultura em conjuntos motor gerador e motor bomba para irrigaÃÃo em propriedades rurais. O experimento foi realizado no municÃpio de Toledo/PR, em duas propriedades, uma com as atividades voltadas para bovinocultura de l

11. Analysis of systems for cooling milk on dairy farms using the biogas generated in CDM projects. / Análise de sistemas para o resfriamento de leite em fazendas leiteiras com o uso do biogás gerado em projetos MDL.
The Brazilian dairy sector is characterized by a great number of producers, presenting low productivity and product quality. Concerning to quality, it is necessary the implantation of cooling systems for milk and conservation on farm. However, a low milk production level and the electric power availability on rural areas sometimes make unfeasible investments

12. Alternativas de financiamento de projetos de biogÃs e geraÃÃo de energia elÃtrica em aterros sanitÃrios: estudo de caso
The objective of the present essay is to analyze how to make feasible the financing of projects for the collection of biogas and the generation of electric power in sanitary landfills, inserted into the clean development mechanism (CDM) of the Kyotoâs Protocol. The exploratory research assesses the current stage of the solid residues in Brazil, the means fo
