1. USE OF INOCULUM IN BIODIGESTERS WITH CATTLE MANURE UNDER CONVENTIONAL AND ORGANIC PRODUCTION SYSTEMS
ABSTRACT One way of making livestock farming a more sustainable practice is to raise cattle organically. However, regardless of the production system, there is a generation of residues that can be converted into energy resources using biodigesters. This study aimed to evaluate the addition of inoculum in the anaerobic biodigestion of cattle manure under orga

2. Estimativa do potencial de recuperação energética de resíduos sólidos urbanos usando modelos matemáticos de biodigestão anaeróbia e incineração
RESUMO Atualmente, um dos grandes problemas enfrentados pelos gestores de resíduos sólidos urbanos (RSU) é a disposição final dos resíduos gerados por sua população. As disposições de resíduos devem ser feitas em espaços e sob condições adequados de modo a minimizar os impactos socioeconômicos e ambientais. Nesse contexto, este artigo teve por

4. 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

5. BIOGAS PRODUCTION FROM DAIRY CATTLE MANURE, UNDER ORGANIC AND CONVENTIONAL PRODUCTION SYSTEMS
ABSTRACT The purpose of this study was to evaluate the production of biogas, as well as the biogas production potential resulting from the anaerobic biodigestion of dairy cattle manure under organic (CMOS) and conventional (CMCS) production system. Also, the concentration of thermotolerant coliforms was evaluated after the biodigestion process. Therefore, be

6. 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

7. Biogas production: litter from broilers receiving direct-fed microbials and an enzyme blend
ABSTRACT The effect of additives used in the feed of broilers on anaerobic bio-digestion of poultry litter was evaluated. Four diets were used: NC: negative control; DFM: NC + 500 ppm direct-fed microbials (DFM) containing Bacillus subtilis and Bacillus licheniformis; ENZ: diet formulated with an enzyme blend (20 ppm phytase, 200 ppm protease and 200 ppm xyl

8. Swine manure digestate treatment using electrocoagulation
ABSTRACT Anaerobic biodigestion is an appropriate alternative for the treatment of swine wastewater due to its biogas generation properties and the possibility of its application as a source of energy for heating or electricity. However, digestate can still contain high levels of turbidity, organic carbon and nutrients and must be correctly managed as a biof

9. Anaerobic bio-digestion of concentrate obtained in the process of ultra filtration of effluents from tilapia processing unit
The objective of the present study was to evaluate the efficiency of the process of biodigestion of the protein concentrate resulting from the ultrafiltration of the effluent from a slaughterhouse freezer of Nile tilapia. Bench digesters were used with excrements and water (control) in comparison with a mixture of cattle manure and effluent from the stages o

10. ProduÃÃo de Ãcidos graxos volÃteis por biodigestÃo anaerÃbia da manipueira / Production of volatile fatty acids by anaerobic biodigestion of manipueira
The cultivation of cassava extends throughout Brazil because of its excellent adaptation to different soils and climatic conditions. Our country occupies the second position at the worldwide ranking in cultivating this plant (15% of the world production). The industrial processing of cassava generates a liquid waste, the so called manipueira, considered as a

12. Reasons for the non-use of the biodigestors in swine farms in Marechal Candido Rondon, PR / RazÃes pela nÃo utilizaÃÃo de biodigestores em granjas suinÃcolas em Marechal CÃndido Rondon â PR
The actual economic model takes the society to exploit the natural resources in an inadequate way, besides generating anthrop systems which are not always in concordance with nature. The swine culture is one of these systems, which needs some policies and actions in order to give the activity some sustainability. This research aimed at identifying the reason
