Bioconversion/ ECOBIOSED


Currently, the problem of ecological threat in the field of solid household waste treatment (SOK) is very urgent around the world. Systems used for their processing by removing sanitary warehouses, composting and incineration are not environmentally friendly and economically justified. Therefore, the use of advanced biotechnologies that use enzymatic agents to support the accelerated decomposition of organic parts, thus completely reducing the sanitary and epidemiological threat for humans, during processing of SOK is of great practical importance.
Consortium Silcon Group Ltd is involved in the development and implementation of innovative ecological technologies on the global market. We use the latest achievements in the field of biotechnology - enzymes from the group "Perma-ZYME", which refer to the class of oxygenases, i.e. carry molecular oxygen. They are complex organic compounds that are produced by fermentation using numerous species of fungi and bacteria. These natural products have no phytotoxicity and are completely safe for humans and the environment. The suggested innovative method of bioconversion is a comprehensive solution for the use of municipal waste landfills and is based on controlled acceleration of natural biodegradation processes within the entire volume of pollutants, causes complete cleaning of the area, as well as restoring the soil function within one vegetative season.

The advantages of this technology include:
• low investment costs for technology implementation;
• high efficiency;
• possibility of control in all stages;
• short deadlines.

Problems of landfills for solid waste from households.
Solid municipal waste (SOK) - this is an ecological problem that causes great concern to the international community. The accumulation of SOK in modern cities reaches up to 300-450 kg per capita per year and is still growing steadily.
Wastes may contain the most diversified toxic and chemical substances (heavy metals, pesticides, surface-active substances, nitrogen-containing compounds, etc.) as well as infectious material that is dangerous to society due to sanitary and epidemiological threat (dysentery, paratyfus, salmonellosis, helminthia, etc.). SOK landfills are flammable and are a source of atmospheric air pollution, soils, groundwater and water facilities of big cities.
Ecological and sanitary hygienic consequences of trash removal do not appear immediately, but within a few years or even decades. Improper disposal of waste is primarily a problem for our descendants!
Thus, the problem of timely and correct disposal of municipal waste and their quickest decomposition on landfills are very important.

Physical, chemical and biological processes that take place within the landfill.
The waste is stored and remains in the landfill for a long time, this ecological system
has an upward trend. The main types of chemical reactions that occur in a landfill
these are oxidation and reduction reactions and pH-dependent reactions. The scope of oxidation-reduction reactions in a landfill depends on the level of oxygen in the waste composition. The degradation of СО2 in water and in the presence of organic acids in the substrate lowers the pH, which means that many metals are insoluble and there is active activation of a significant amount of waste in the landfill, which is a source of environmental pollution. Indicators for the migration of chemicals outside the storage site are higher levels of Ca, Mg, Cl, conductivity, total organic oxygen, biological oxygen demand, and chemical oxygen demand, etc.
In general, biological degradation can occur under aerobic and anaerobic conditions.
Oxygen decomposition continues until all oxygen (O2) contained in the composition and dissolved in liquid waste is used up. Unfavorable oxygen reaction products are heat, СO2, Н2О and inorganic material with a large number of oxygen molecules available to complete the reaction. In practice, the duration of the aerobic phase is relatively short and depends on the design solutions and conditions of use of the plot, including the degree of waste density and moisture content (humidity replaces air in the space between waste particles). Microbes, active in this phase, are primarily necessary and optional - aerobes. During the aerobic stage, the inside temperature of the polygon can be 45 - 55 ° С. The negative impact on the environment during the aerobic phase is minimal, and the final main biodegradation products are neutral inorganic solids, СО2 and Н2O. Although intermediate decomposition products can be discharged during the aerobic phase, their quantity and relative contribution to environmental pollution are negligible. Although both phases are important, anaerobic degradation results in a stronger and longer impact in terms of polygonal properties. Most of the biodegradable organic matter of the plot is subject to anaerobic biological processes. Microorganisms responsible for anaerobic degradation include both facultative and essential anaerobes. Among other properties, the main difference between aerobic and anaerobic phases is the lack of noticeable heat formation through this phase. Thus, during the anaerobic step the waste temperature in the polygon gradually decreases from the high values ​​characteristic of the aerobic phase to practically the ambient temperature.
In general, two groups of undesirable products can be distinguished in the anaerobic phase: 1) volatile organic acids; 2) gases.

The principle of operation of the ECOBIOSED enzymatic agent.
ECOBIOSED is a concentrated enzyme that contains special additives in its composition, which allows it to be used in a variety of ways, including the bio-destruction of household waste and the "processing" of compost mass into high-performance organic fertilizers. The enzyme effect of ECOBIOSED is directed first to the activation, including the activation of the enzymatic activity of the microflora.
ECOBIOSED refers to enzymes of the oxygenase class, which leads to the oxidation of organic compounds by activated molecular oxygen or oxygen from superoxides. According to the physical properties in the enzyme group, it is known that they have a low surface tension and, as a result, high power penetration, and thus oxygen supply.

The use of enzymes from the class of oxygenase supports the intense penetration of oxygen from the air into deeper layers of SOK in the landfill and extends the zone of aerobic processes of decomposition of organic substances, which in this way significantly accelerates the process. In addition, the enzymes, as catalysts of the biological reaction, provide complete degradation of organic substances.

The ECOBIOSED enzyme in working concentrations does not affect the mechanical strength of the damp insulation material made of polyethylene on landfills!

Thus, the enzyme "ECOBIOSED used in industrial conditions on SOK landfills enables acceleration and deepening the decomposition of organic substances, which ensures a reduction in the volume of deposited wastes and improves sanitary and hygienic conditions of landfills.

Conditions and methodology of using ECOBIOSED. Equipment.
1) The optimal range of operating temperatures in which the bioconversion of SOK storage sites is possible is 15-25 ° С. This factor has a significant impact on the process of biodegradation and enzyme action!
2) On the SOK dump, a set is completed, which consists of a tank purification reactor, a filtration system and pumps.
3) Perforated pipes, so-called "introduction wells" for ECOBIOSED delivery are introduced into the storage yard without excavation.
4) At the same time, based on enzymes, solutions are made that are mixed with process water and are supplied in "introduction wells" or dispersed through pumps along the storage site.
5) The scope of ECOBIOSED operation is up to 7 m! The recesses are arranged so that their coverage overlaps.
6) The check is carried out every day, individually for each well! It consists in collecting and analyzing the results of samples, as well as choosing the concentration of the agent within range (~ 0.01 mg of ECOBIOSED solution per 1 kg of SOK or 20 g of dry product per 1 ton of SOK).
7) Garbage is sorted and processed after decontamination and destruction of organic substances.
The volume and, at the same time, SOK sedimentation value on the landfill is determined by surface surveying of storage sites and determination of the geodetic height. The excavator, scraper, tractor with trailer and bulldozer are used for packing and stacking waste. Special drilling equipment is used to install the introduction wells.

The effect of ECOBIOSED in chemical and biological processes in the landfill.
The effect of the enzyme ECOBIOSED begins to be visible already 24 hours after application. Above all, the lack or significant reduction of malodour is immediately noticeable. Warning! The temperature of the medium on the second day increases by 1 - 3 ° C, as a consequence of highly energetic microbiological processes under the influence of ECOBIOSED.
The effluent begins to appear on the third day, whereas it happens only after the fifth day under normal conditions. As results from the detailed chemical and biological analysis of the sample (Table 1), the effluent from the section on which ECOBIOSED is used is more saturated with organic components. At the same time, the content of phosphates, sulphates and chlorides under the influence of the enzyme decreased, which indicates a more intensive decomposition of organic components in SOK under the influence of ECOBIOSED during the amonification step of the substrate.

The enzyme activity is particularly evident after microbiological damage to the substrate: numerous macroscopic fungal, mold and yeast colonies appear on the surface of the substrate within 56 hours. These are mainly representatives of species:
Aspergillus, Cladosporium, Fusarium, Penicillium, Trichoderma, Trichosporon, Saccharomyces, Rhodotorula. The beginning of structuring is observed from the moment when the substrate is damaged by fungi, i.e. it is further transformed into a homogeneous / homogeneous mass of humus. An intensive hypertrophy of the fungal substrate occurs for 1.0-1.5 weeks. Next, this process becomes weaker.
In the initial stages (7-10 days), the number of microorganisms increases rapidly to 10 billion cells per 1 gram), their activity is repeatedly increased, and as a consequence, there is a more energetic process of waste treatment, especially its organic part. The size and weight of SOK is reduced twice on the 14th day of enzyme action!
Bacteria that do not produce spores play a major role in the progress of SOK dumps and the number of bacilli and actinomycetes is not large.
