Abstract Sludges produced in biological wastewater treatment plants have rich organic materials in their characteristics. Recent research studies have focused on the energy recovery from sludge due to its high organic content. The gasification process is a thermal conversion technology transforming the chemical energy contained in a solid fuel into thermal energy and electricity. The produced syngas as a mixture of CO, CH4, H2 and other gases can be used to generate electrical energy. The gasification of yeast industry sludge has been experimentally evaluated in a pilot scale downdraft-type gasifier as a route towards the energy recovery. The gasifier has 20 kg biomass/h fuel capacity. During gasification, the temperature achieved was more than 1,000°C in the gasifier, and then the syngas was transferred to the gas engine to yield the electricity. A load was connected to the grid box and approximately 1 kWh electrical power generation for 1 kg dry sludge was determined. The characteristics of residuals – ash, glassy material – were also analyzed. It was found that most of the heavy metals were fixed in the glassy material. Experimental results showed that the yeast industry sludge was an appropriate material for gasification studies and remarkable energy recovery was obtained in terms of power production by using syngas.

The importance of coal pyrolysis studies for the development of energy technologies is evident, since pvrolysis is the first stage of any process of coal thermal conversion. In combustion, pyrolysis determines conditions of coal ignition and the rate of char after-burning, in gasification, pyrolysis determines total yield of gasification products. It must be noted that in modern energy technologies pyrolysis occurs at high late of coal particle heating (=10 K/s for different fluidized bed, or FB-technologies) or super-high-rate (>10**5 K/s for entrained-flow gasification), and in some of them at high pressure. In CETI during last 12 years the detailed study of pyrolysis in FB laboratory-scale PYROLYSIS-D plant and entramed-flow pilot-scale GSP-01 plant, was carried out. In this paper main results of mentioned investigations are given. Kinetic constants for bituminous coals and anthracite high heating rates in entrained flow for high temperatures (>1500 ?C and >1900 ?C), and in fluidized bed conditions in temperature range 972-1273 K. In order to describe data obtained in fluidized bed conditions, G--model based method of calculation of devolatization dynamics was suited to FB heating conditions. Calculated and experimental kinetic data are in good agreement. The result proves that at FB-pvrolysis conditions intrinsic mass-transfer limitations are negligible and devolatilization is really kinetic-controlled.

The paper considers approaches to standardizing the volumes of accumulation of solid municipal waste in the constituent entities of the Russian Federation. The analysis of normative legal acts, which determine the specific norms of solid municipal waste at the regional level, is carried out. In the work, based on the results of the conducted scientific research, general and particular factors have been identified that take into account the socio-economic characteristics of the region, which govern the regions when determining the accumulation standards. It has been proved that the differentiation of the standards for the accumulation of solid municipal waste, applied in practice, does not lead to an increase in the forecast accuracy, significantly complicating the calculations. Approaches are proposed for optimizing the system for calculating the accumulation rate, taking into account the main socio-economic conditions, which, according to the authors, will have a greater effect on the real volume of accumulation of solid household waste: the unevenness of their formation in natural and climatic zones and geographic conditions, living standards, as well as seasonal characteristics of movement and place of residence of the population at different periods of time. We believe that it is necessary to develop a unified approach to monitoring the standards for the accumulation of solid household waste, based on indicative assessments of each factor with a different degree of their influence. In the future, the proposed approach will make it possible to provide reliable and objective information and to monitor and control the volume of accumulation of solid household waste.
