Abstract-Dry poultry waste can be used as a valuable fertilizer for seedbed preparation and spring fertilizing of winter crops. One of the major limitations for the direct application of organic waste in the soil is the presence of conditionally pathogenic and pathogenic microorganisms, preserving viability and virulence for a long time. The low-temperature pyrolysis of pelleted litter mass at 250° C and treatment time of 60 min. allows for complete decontamination of this type of waste. Reducing the pyrolysis temperature to 155 ° C even when the treatment time was 60 min. did not fully decontaminate the litter mass. There was also a series of experiments on the use of pelleted litter mass subjected to low-temperature pyrolysis for 1 hour at 250 ° C as a fertilizer. It was found that by introducing these pellets into the soil in an amount of 2 tons/ha, the barley yield increased by 16.2%; the timing of fruit formation of the tomato variety "Krasavets" reduced from 70 to 62 days from the start of germination, and the starting date of ripening decreased from 95 to 82 days; the yield of "Santana" potato variety increased by 36.5% up to 62 tons/ha.

“…The main reasons are limited fossil fuel resources, as well as the strategies of 'sustainable development' and 'waste minimization' that are promoted throughout the world. Recently many papers have been published on those issues, either dealing with larger implementation of renewable fuels and biomass for power production [1][2][3][4][10][11][12][15][16] or focused on fuel processing and energy recovery [5][6][13][14]17]. However, since those fuels contain quite large amounts of moisture, they are characterized by relatively low energy density, low LHV (low heating value), and often contain significant amounts of pollutants like, e.g., chemically-treated energy crops.…”

“…The biomass for those technologies is usually processed in order to get rid of moisture and increase the process efficiency, and so far, many fuel pretreatment technologies have been investigated, mostly based on gasification, pyrolysis, or hydrothermal treatment as discussed in [2][3][4]7,[13][14][15]17,[27][28][29] among others. Although well managed in lab scale, those processes are quite expensive and thus still not very much profitable in commercial operation [7].…”

“…Therefore, apart from fuel processing in order to produce gas or bio-oils, other researchers have focused their investigations on fuel processing, to obtain solid residue the called 'biochar' or 'biocarbon'. This approach seems to be a more interesting way for inexpensive and efficient production of power from renewable/alternative fuels since it is technically simpler, much cheaper, and can be easily adopted for power production [10][11][12][13][14][15][16][17][18][19][20]. Should it be possible to combine the processing of biomass and the production of power with simultaneous minimization of the emission of carbon dioxide to the atmosphere [20,21], additional significant environmental benefits might also be achieved.…”

The paper presents the results and analysis of biomass processing in order to provide the conditions for the most profitable use of the biomass in modern and efficient power generation systems with particular attention put on the decrease of the emission of carbon dioxide (CO2) and no need to develop carbon capture and storage plants. The promising concept of CO2 storage via the production of biochar and the advantages of its application as a promising carbon sink is also presented and the results are supported by authors' own experimental data. The idea enables the production of electricity, as well as (optionally) heat and cold from the thermal treatment of biomass with simultaneous storage of the CO2 in a stable and environmentally-friendly way. The key part of the process is run in a specially-designed reactor where the biomass is heated up in the absence of oxygen. The evolved volatile matter is used to produce heat/cold and electricity while the remaining solid product (almost completely dry residue) is sequestrated in soil. The results indicate that in order to reduce the emission of CO2 the biomass should rather be 'cut and char' than just 'cut and burn', particularly that the charred biomass may also become a significant source of nutrients for the plants after sequestration in soil.

Abstract-Wood fiber waste is abundantly produced from the medium density wood fiber industry. The production of carbon from biomass is having more intention from the researcher due to the application. In this research, the conversion of biomass from wood fiber waste into carbon particle via hydrothermal carbonization (HTC) process is chosen. In this experiment, wood fiber and water were added in a pressure vessel and heated up to temperature between 200 -220°C for 4 hours. Analyses were carried out using Elemental Analyzer, TGA, FTIR and FESEM for the characterization phase. The carbon value recorded an improvement as the O/C ratio of raw material is higher than the HTC products. The surface morphology obtained from FESEM showed pores on the surface of the HTC product suggesting a processing route to complicated carbon based structures. It can be concluded that both processes is practicable method to convert biomass into value added product.
