[Production of Methane in Anaerobic Digestion of Organic Waste of Vegetable Processing Facilities].

The article concerns converting waste from vegetable processing facilities into methane in anaerobic reactors with a small amount of inoculum (8.4%). Anaerobic digestion of vegetable waste with a high content of organic acids and carbohydrates makes it possible to achieve a methanogenesis productivity of 273–436 L CH4/kg of volatile solidis, which is comparable to or higher than the productivity of such reactors in the world (according to the literature).

[Intensification of Microbial Decomposition of Organic Fraction of Municipal Waste: Laboratory and Field Experiments].

Methods of intensifying the anaerobic microbial decomposition of the organic fraction of municipal solid waste (MSW) on an MSW landfill and in anaerobic reactors were studied. It was discovered that it is preferable for the initiation and stabilization of the process of anaerobic digestion of organic waste in laboratory bioreactors at 20 and 50 degrees C to use a mixture of activated suspension of soil from the anaerobic zone of the landfill and digested sewage sludge. Stimulation of methanogenesis was shown in field conditions when digested sewage sludge was added directly into the upper layer of anaerobic zone of the landfill.
