SYSTEM THAT PROVIDES RECYCLING OF DOMESTIC SOLID WASTES AT THE SOURCE AND OPERATING METHOD THEREOF

Technical Field of the Invention

The present invention relates to a system that enables the recovery of domestic solid wastes without separation and the operating method thereof.

In particular, the present invention relates to a system that can automatically separate glass and metal wastes from other domestic wastes, and that can generate electrical energy during this separation and transfer this energy to the power line or store it in its own battery, and the operating method thereof.

State of the Art

Materials made of plastic and packaging wastes, which provide a very easy use feature especially for people in daily life, constitute the majority of urban solid wastes. When used plastic and other packaging wastes are thrown into the nature, they can remain undegraded for a long time due to their resistance to physical, chemical and biological degradation processes. Since plastic and packaging wastes pollute the environment for many years, treating them with appropriate disposal methods is of great importance for the environment and human health. The storage and elimination of organic wastes as well as plastic and packaging wastes have a major role in preventing environmental pollution in daily life.

With the development of modem life in the world, different methods are being developed for the management of plastic waste and organic waste. Thermal methods such as pyrolysis, gasification and incineration are the most commonly used methods for both disposal and recycling of plastic wastes in order to generate energy. In all of these systems, energy is produced by using only certain types of plastic. Organic wastes are mostly processed randomly by wild storage method although recyclingbased processes are desired in the organic fraction of domestic solid wastes. The most known recovery method is the incineration method. When it is not performed with the necessary engineering principles, it causes a large amount of air pollutant emissions to the environment and causes environmental pollution. Organic wastes are also recovered through biogas production and energy generation.

Conversion of waste plastics and tires into pyrolytic oil by pyrolysis is on the agenda as a method for converting pyrolytic oil, which has been the subject of many studies in our country and the world in recent years, into electrical energy.

Williams and Williams, In their study in 1999, proposed the pyrolysis of mixed plastic waste as a recovery method to produce a petrochemical feedstock in organic waste, especially on the pyrolysis of waste plastics [1 ], In the study, 6 types of plastics found in municipal solid wastes were used. These plastics are high density polyethylene, low density polyethylene, polypropylene, polystyrene, polyvinyl chloride and polyethylene terephthalate. Each of the waste plastic grades was pyrolyzed by heating to a final temperature of 700°C in a fixed bed reactor with a temperature increase of 25°C per minute. The polystyrene was then mixed with the other five plastics in a 1 :1 ratio and pyrolyzed under the same conditions. The yield and composition of the pyrolysis oil and gases obtained from these experiments were determined. The main gases obtained from individual plastics were determined as hydrogen (H2), methane (CH4), ethane (C2H6), ethylene (C2H4), propane (CsHs), propene (CsHe), butane (C4H10) and butene (C4H8), and carbon dioxide (CO2) and carbon monoxide (CO) were also obtained from the PET sample. Hydrogen chloride gas was obtained separately from PVC waste. It was determined from the pyrolytic oil analyzes that it is an oil with aliphatic composition consisting of a series of alkanes, alkenes and alkadienes from polyalkene plastics (YYPE, DYPE and PP), and PVC wastes mainly gave an aromatic oil yield, in addition, PS and PET wastes with aromatic groups in their structures showed a more aromatic composition. The gas ratio obtained from PS wastes was higher than other plastic wastes. The ratio of pyrolytic oil from mixed plastic waste was found to be less efficient than in single trials. Compositional analysis of the pyrolysis oil showed that it was produced by a mixture of aromatic hydrocarbons and changes in the concentration of polycyclic aromatic hydrocarbons compared to what would be expected from each plastic waste. On the other hand, in his study conducted in 2019, Sankap presented a new proposal for the recycling of plastics by plastic pyrolysis by considering the six main plastic types individually and sharing the outputs obtained as a result of their pyrolysis [2],

UK-based Cynar PLC Company has been successfully producing aviation fuel in Ireland, Spain and South America since 2004 with the argon washing method they developed, on the production of usable fuel from plastic waste by pyrolysis method in the world. Companies producing pyrolytic oil or electrical energy from solid wastes in our country and in the world establish large-scale facilities in order to meet their production expenses and make a profit, and certain plastic wastes or waste vehicle tires are used in all of these facilities. In our country, electrical energy production from waste tires is carried out by various companies. However, it creates a new problem in our country both in terms of cost and environment since this transformation is performed not only to reduce the tires in our country, but also by purchasing imported waste tires.

The Turkish Statistical Institute (TUIK) determined that 78.3 million tons of 127.4 million tons of waste processed in municipal waste disposal and recovery facilities were disposed of and 49.1 million tons were recovered. In 2016, 61.2% of the collected waste was sent to landfills, 28.8% to municipal dumps, 9.3% to other recycling facilities, and 0.5% to compost facilities, while 0.2% was disposed of by other disposal methods; and In 2018, 67.2% of the collected waste was sent to landfills, 20.2% to municipal dumps and 0.4% to compost facilities, while 0.2% was disposed of by other disposal methods. It was determined that 11.9% of the waste collected in 2018 was sent to other recycling facilities. The Turkish Statistical Institute (TUIK) determined that 1387 out of 1389 municipalities provided waste services in 2020, and 69.4% of the 32.3 million tons of waste collected in municipalities where waste services are provided is sent to landfills, 17% to municipal dumps and 13.2% to recycling facilities, while 0.4% of these were determined to be disposed of by being burned in an open area, buried, poured into a stream or land. According to TUIK data, the average daily amount of waste per person collected in municipalities is calculated as 1 .13 kg (TUIK 2020 Waste Statistics), and according to the data collected from the preliminary studies, approximately three kg of mixed domestic waste products are thrown away from a household of four people per day. Glass and metal waste are not included in these waste products. Accordingly, based on previous data, the daily average amount of liquid fuel that can be obtained from a household with this system is approximately 300 g, the amount of gaseous fuel is approximately 300 g, and only 165 g of solid residue is obtained daily.

When the electrical energy calculation is made based on the thermal values of the fuels, 860 kcal/kg corresponds to exactly 1 kWh electrical energy. In other words, the electrical energy obtained with 1 kg of fuel with a calorific value of 10,987 kcal/kg is approximately 12.78 kWh. According to the liquid fuel values mentioned above, the average amount of electrical energy that can be obtained daily with 3 kg of mixed domestic waste product from a house can be calculated as 11 .50 kWh. In addition, the average amount of electrical energy that can be obtained from gaseous fuel values is calculated as 11 .50 kWh.

The systems used in the field of energy from waste in our country and in the world are designed on a large scale, and it is not possible to use all of these systems without separating the garbage. These systems are systems that require large-scale processing by separating the garbage outside.

The reason for such low rates of recycling data is the lack of awareness of waste separation at home in Turkey. In our country, the lack of awareness of garbage separation at home also brings an added cost to waste recycling facilities. For this reason, the rate of waste sent to "Regular Storage" and "Incineration Facilities" is approximately 2 times higher than the waste sent to "Recovery Facilities".

Currently, there is no system in the world that simultaneously recycles solid wastes such as organic, plastic, etc., and converts them into energy. The biggest disadvantage of these systems used for recycling today is the necessity of separating wastes such as glass, metal, paper, cardboard, etc. before placing the waste in the recycling system.

In the state of the art, there are applications for recycling separated wastes, studies for obtaining energy from these wastes, patent or utility model applications. One of them is the system of separating domestic wastes at source, which is the subject of the utility model numbered "TR 2019/06959". Said invention enables the separation of paper, plastic, metal, glass, battery, and organic wastes at the source thereof according to the type of waste. The waste separation window, which is opened and closed with opening and closing magnets, comprises waste separation lines located separately for each waste and a waste sorting center where the wastes are separated and sent with the help of these lines.

Another application in the state of the art is the patent application numbered "TR 2016/08222". The invention relates to an industrial and domestic waste-to-energy production method and a reactor suitable for this method, which is used for the disposal of all kinds of organic-based industrial and urban wastes in compliance with environmental conditions and energy production. It is stated that said reactor comprises a waste inlet where the wastes enter the system first, a first pipeline that carries the wastes entering from the waste inlet to the top, a transfer pipe through which the wastes to the highest point in the first pipeline are transferred, the gasifier unit where the wastes in the transfer pipe enter, non-gasified waste transfer pipe from which non-gasified wastes exit in the gasifier unit, a second pipeline where the wastes in the non-gasified waste transfer pipe are transferred, ash outlet at the bottom of the second pipeline, filter syngas outlet located at the top and bottom of the gasifier unit, and unit chassis housing the gasifier unit.

Another application in the state of the art is the patent application numbered "TR 2019/06194". Said invention relates to a pyrolysis chamber for treating domestic waste. The garbage input material is loaded into a domestic designed thermal conversion unit, either directly or after a pre-treatment such as shredding. The feedstock is converted to fuel through a thermal treatment such as pyrolysis. The resulting output of oil and gas can be stored or fed into a boiler unit for use as a fuel to produce hot water or to power said dwelling, or to operate an electricity generation unit for the tariff for sale to the grid. However, this system is intended to create liquid and gaseous fuels by pyrolysis of domestic waste only. This system only describes a domestic pyrolysis reactor and it is impossible for the system to be used by users without separation.

The invention of the patent numbered "CN216757629U" in the state of the art relates particularly to a system for the co-processing of kitchen waste and domestic waste, waste sourcing and harmless treatment area. It is disclosed a food waste and domestic waste co-processing system, characterized by comprising a kitchen waste pretreatment system, a domestic waste and a kitchen waste mixing system. Waste pyrolysis gasifier pyrolyzes and gasifies mixed domestic waste and kitchen waste. Then, the electricity or heat produced after the combustion of the produced gas is used as energy output. The solid-liquid separation device separates the crushed kitchen waste from solid and liquid to obtain liquid phase materials and solid kitchen waste.

The oil removal device performs oil removal on liquid phase material after solid-liquid separation to separate oil and water to obtain oil phase material and water phase material and water phase material.

The invention of the patent numbered "CN216667681 II" in the state of the art relates particularly to a common pyrolysis treatment system for kitchen waste and domestic waste. It comprises a receiving device, a crushing device, a first solid-liquid separation device, a second solid-liquid separation device, an oil extraction device, and a dewatered food waste conveying device. The food waste and domestic waste copyrolysis treatment system can realize the synergistic energy treatment of domestic waste and food waste, as well as solve the single raw material problem in traditional waste treatment technology. There is a leachate collection device on the outside of the bottom of the garbage collection tank next to the kitchen waste pre-treatment system. The leachate collection device is a storage tank structure and communicates with the bottom of the garbage collection tank through a filter screen to collect garbage.

The disadvantage of the disclosed systems is that it is not possible to use the garbage without separation in all the systems available in the art. They are systems that require large-scale processing by separating the garbage outside. Users recycle their waste by sorting and/or obtain energy. Therefore, there is a need for a technology that can automatically separate glass and metal waste from other domestic wastes, and that can generate electrical energy during this separation and transfer this energy to the power line or store it in its own battery.

Another disadvantage of the current system is the large-scale design of the systems used in the field of energy generation from waste in our country and in the world. When the studies are examined, no system suitable for domestic use has been encountered, which does not require the user to separate the wastes in order to recycle mixed domestic wastes and/or obtain energy. Therefore, a domestic system is required.

Consequently, the disadvantages disclosed above and the inadequacy of available solutions in this regard necessitated making an improvement in the relevant technical field. Brief Description and Objects of the Invention

The most important object of the present invention is to produce electrical energy by throwing mixed domestic wastes into the waste bin without any sorting process, and to separate glass and metal wastes at the end of the process. The system developed with the present invention is a system that can automatically separate glass and metal waste from other domestic wastes, and that can generate electrical energy during this separation and transfer this energy to the power line or store it in its own battery. For this purpose, mixed domestic wastes are subjected to pyrolysis at temperatures between 500°C and 630°C. Liquid and gaseous products produced in the pyrolysis process are converted into electrical energy with gas fuel and liquid fuel generators suitable for the system. At the same time, at the end of the process, glass and metal wastes are separated. Thus, recycling is supported.

Another object of the present invention is to develop a designable recycling dustbin of any size. The recycling dustbin developed with the invention is of usable size at home. The user can take this system with his/her to her home, workplace, wherever he/she desires, just like a generator, and use it instantly. In this way, ease of use is provided in terms of renewable energy. The system can be used anywhere and anytime in terms of low maintenance costs and being a small-sized system.

Another object of the present invention is to prevent the heat generated by the pyrolysis process from escaping to other parts of the system and out of the system. For this purpose, in the present invention, coil insulation on the electrical resistance system can be used to ensure that the heat obtained is not given to the outside. In addition, there is rock wool insulation in order to provide insulation between the fuel cooling core system and the waste bin with an electrical resistance system around it. In addition, there is a rock wool insulation between the part where the gas and liquid fuel generator is located and the fuel cooling core system in order to ensure the thermal insulation of the system. In this way, the transfer of heat between sections to other sections can be prevented.

Yet another object of the present invention is to ensure a smooth positioning while performing the electricity generation process by performing the pyrolysis process in the garbage can. For this purpose, servo driver and servo motor are also used in the present invention. Yet another object of the present invention is to contribute to recycling by collecting glass and metals in a separate chamber while ensuring their recovery without separating them from domestic waste. For this purpose, in the present invention, there is a metal and glass separation drawer to which the bottom cover of the waste bin is attached. After the heat treatment (pyrolysis) is completed by the electrical resistance system, glass and metal wastes accumulate in the glass and metal separation drawer. The user can then take glass and metal waste from this drawer and contribute to recycling.

Yet another object of the present invention is to enable the user to control the processes taking place in the trash system. Thus, there is also a control panel that allows for displaying how much liquid fuel is collected, temperature and pressure values.

Yet another object of the present invention is to reduce the wild storage areas. By means of the present invention, the effect of wild landfills on environmental pollution can be minimized by reducing the wastes thrown into the nature, and it can contribute to the prevention of various problems related to the incineration of solid wastes.

Yet another object of the present invention is to separate many raw material value materials more easily. Elimination of garbage separation in countries where there is no awareness of waste separation at home, and easier separation of many raw materials that will be used for recycling in the world can be achieved with glass and metal separation drawers.

Detailed Description of the Invention

In particular, the present invention relates to a system that can automatically separate glass and metal wastes from other domestic wastes, and that can generate electrical energy during this separation and transfer this energy to the power line or store it in its own battery, and the operating method thereof. The waste bin (26) in the system is completely made of chrome or a suitable equivalent material. In addition, it may have a diameter of 25 cm, a height of 40 cm, a cylindrical shape and a wall thickness of 3 mm, or it may be enlarged as desired according to the place of use and requirement. The waste bin (26) comprises waste bin bottom cover (6) so that it can be opened from the bottom side and the waste bin top cover (4) so that the users can throw their garbage. As can be seen in Figure-2, there is a main gas outlet pipe (1 ), pressure control valve (2), and thermocouple (3) on the waste bin top cover (4). J type Thermocouple (3) is preferred due to the temperature range in the system. K type thermocouples or E, R, S and B type thermocouples that can operate in higher temperature range can also be used in the system.

The connection section of the main gas outlet pipe (1 ) with the cooling system is T- shaped as can be seen in Figure-1 , and at the upper end, there is a solenoid water vapor outlet valve (13), at the other end there is a solenoid gas outlet valve (14) and its connection to the fuel cooling core system (16). The gas coming out of the main gas outlet pipe (1 ) is recognized, the water vapor outlet pipe (15) valve is closed and both solenoid gas outlet valves (14) are opened. There is a carbon monoxide sensor (12) in front of the solenoid gas outlet valve (14) to operate the gas and liquid fuel generator (22). The electrical resistance system (5) is wrapped around the waste bin (26) in the system that ensures the recycling of domestic solid wastes without separation. It can be ensured that the heat obtained is not given to the outside by making serpentine insulation (10) on the electrical resistance system (5). At the same time, it can reach a temperature of 630°C in a short time such as 30 minutes. J type thermocouple (3) is used, which operates between 0°C and +750°C in order to ensure that the electrical resistance system (5) operates automatically at the set time.

Servo driver and servo motor are used for automatic opening and smooth positioning of the waste bin bottom cover (6) and the waste bin top cover (4). The waste bin bottom cover (6) is connected to a two-drawer separation system for separating metal, glass, and ash waste. These drawers are the glass and metal separation drawer (8) and the ash separation drawer (9). After the heat treatment (pyrolysis) is completed by the electrical resistance system (5), glass and metal wastes accumulate in the glass and metal separation drawer (8). The remaining wastes accumulate in the ash separation drawer (9). The bottom cover of the glass and metal separation drawer (8) is in the form of a grid and there is an ash discharge latch thereon in order to ensure that the waste is transferred to the ash separation drawer (9).

The waste bin top cover (4) is connected to the main gas outlet pipe (1 ) and four fuel cooling core systems (16), 30 cm wide and 20 cm high, made of chrome material. There is rock wool insulation (11 ) in order to prevent the heat transfer between the fuel cooling core system (16) and the waste bin with an electrical resistance system (5) around it. In addition, there is also a rock wool insulation (11 ) between the part where the gas and liquid fuel generator (22) is located and the fuel cooling core system (16) in order to ensure the thermal insulation of the system. Thus, the transfer of heat between sections to other sections can be prevented. There is also an external protection (7) for protecting the rockwool insulation (11 ) and the outer part of the waste bin (26).

There is a liquid fuel product outlet pipe (19) in the lower part of the fuel cooling core system (16) and a gaseous fuel product outlet pipe (18) in the upper part. Gas fuel product outlet pipe (18) and liquid fuel product outlet pipe (19) are connected to gas and liquid fuel generator (22), which can run liquid and gaseous fuel together at different time intervals. There is an electric floater and a buoy (20) to measure the liquid level inside the liquid fuel tank (17) where said fuel cooling core system (16) is connected with the liquid fuel product outlet pipe (19). There is a liquid outlet valve (21 ) on the liquid fuel tank (17) in order to transfer the liquid fuel in the liquid fuel tank (17) to the gas and liquid fuel generator (22). The liquid outlet valve (21 ) works automatically as in other valves and is connected to the control system with fireproof cables.

A pressure control valve (2) is used on the waste bin top cover (4), considering problems such as clogging of the gas pipe that may occur in the system, overheating of the system, and leakage when the system is in operation. In addition to the pressure control valve (2), there is also an automatic control system in the system that ensures the recovery of domestic solid wastes without separation. In the automatic control system, there can be elements such as remote control, time relay, sensor control devices, temperature control devices, digital panel meters, graphic-multi-displays, touchscreen graphic panels, programmable controller, supervisor control and data acquisition systems, and distributed control system (DCS).

It can be automatically closed or opened with the keys on the control panel (25) or the touch screen by means of the automatic control system, the electrical resistance system (5) starts to operate automatically at the set time by means of the keys on the control panel (25) or the touch screen, automatic closing or opening of the bottom cover of the waste bin (6) is provided by the keys on the control panel (25) or the touch screen, the solenoid water vapor outlet valve (13) is automatically closed and the solenoid gas outlet valve (14) is opened by recognizing the water vapor outlet with the carbon monoxide sensor (12), the gaseous fuel coming out of the fuel cooling core system (16) is recognized and automatically transferred to the gas and liquid fuel generator (22) by means of the carbon monoxide sensor (12), the liquid fuel coming out of the fuel cooling core system (16) is transferred from the liquid fuel tank (17) to the gas and liquid fuel generator (22) at the desired time by means of the carbon monoxide sensor (12), and the gas and liquid fuel generator (22) can be operated automatically.

First of all, when the system is empty and closed, the waste bin top cover (4) is opened by pressing the unlock button on the control panel for the operation of the system that ensures the recovery of domestic solid wastes without separation. When the waste bin top cover (4) is opened, the temperature and pressure indicators on the control panel (25) start to operate. The control panel (25) can be touch or keyed. After the system starts to work, garbage (domestic waste) is thrown into the waste bin (26) and when the close button on the control panel (25) is pressed, the top cover of the waste bin (4) is closed, thus, the electrical resistance system (5) that surrounds the waste bin (26) starts to operate. The operation of the electrical resistance system (5) can similarly be seen on the control panel (25) by the user. By means of the keys on the control panel (25) or the touch screen, it is also possible for the user to operate the system at any time.

From the moment the system starts to operate, the solenoid water vapor outlet valve (13) is in the open state, the solenoid gas outlet valve (14) and the liquid outlet valve (21 ) are in the closed state. As soon as the carbon monoxide sensor (12) located in front of the solenoid water vapor outlet valve (13) detects gas, it closes the solenoid water vapor outlet valve (13), which is connected to the control system with a fireproof cable, and provides the opening of the solenoid gas outlet valve (14) and the liquid outlet valve (21 ). The gas and liquid fuel generator (22) starts to operate simultaneously with the opening of the solenoid gas outlet valve (14).

During the liquid fuel exit from the liquid fuel product outlet pipe (19), how much liquid fuel is collected can be seen on the control panel (25) by means of the electric floater and the buoy (20) connected to the control system with a fireproof cable. Afterwards, when the gas end is detected by the carbon monoxide (12) sensor, the gas and liquid fuel generator (22) is turned off and electricity is produced. Meanwhile, it can be seen from the control panel (25) that the gas and liquid fuel generator (22) stops. The system also comprises a generator exhaust pipe (23) to minimize vibrations in the gas and liquid fuel generator (22) and to prevent damage to the exhaust system of the generator.

Subsequently, in the system, the electrical resistance system (5) is turned off and the pyrolysis process is terminated as soon as the end of the liquid fuel outlet and the end of the gas outlet are detected by the carbon monoxide sensor (12). Approximately two hours after the pyrolysis process has ended and the system has started to cool, The waste bin bottom cover (6) is being opened since it is a sliding system, and glass, metal and ash wastes remaining at the bottom of the waste bin (26) are discharged into the glass and metal drawer (8). Then, the user can take the glass, metal and ash wastes by emptying the remaining ash residue into the ash separation drawer (9) by the grill latch in the glass and metal drawer (8).

The waste bin top cover (4) is opened approximately three hours after the pyrolysis process is completed, thereby accelerating the cooling process. By means of the thermocouple (3) in the waste bin (26), when the system temperature drops below 40°C, the waste bin top cover (4) is closed, making the system ready for operation again.

In the system that ensures the recycling of domestic solid wastes without separation, optionally, it can offer the conversion of the fuel in the liquid fuel tank (17) into electricity in the gas and liquid fuel generator (22) or its conversion afterwards. The user can convert the stored liquid fuel into electricity from the gas and liquid fuel generator (22) at a desired time. This energy is output from the electrical energy output panel (24), which is connected to the gas and liquid fuel generator (22). In addition, after the process of converting the stored liquid fuel into electricity is completed, the liquid fuel cycle starts immediately as soon as it is detected by the carbon monoxide sensor (12).

By means of the system described in the present invention, the total amount of electrical energy that can be obtained from a house on average is 23 kWh. The amount of energy that the system will consume during its operation is 9.3 kWh on average, including the amount of energy required to remove the moisture (water vapor) contained in the waste from the system. Considering these data, the average amount of electrical energy that the system can obtain daily is 13.7 kWh. When this amount is considered on a monthly basis, an average of 411 kWh electrical energy is obtained. Accordingly, a family of four can gain an average of 181 kWh of electrical energy in a month with offsetting in said system.

By means of the present invention, mixed domestic wastes can be converted into electrical energy without separation instead of the waste bins used in homes and the garbage containers used in neighborhoods, and this converted electrical energy can be directly returned to the line. Or it can be stored optionally. While this system obtains electrical energy from waste types such as organic waste and plastic waste, it also can perform the garbage separation process automatically by separating the glass and metal wastes in the mixed wastes. In this way, an environmentally friendly method has been developed that is compatible with the zero waste principles, which is one of the national waste policies.

By means of the system developed with the present invention, it will be possible to reduce the garbage collection trucks of the municipalities and as a result, significant savings in fuel used in garbage trucks, which require high costs, and support for the Ell Green Deal Zero Emissions goal can be provided.

The reduction of wild landfills can be achieved due to the reduction of discarded waste. In addition, by means of the reduction of wild landfills, the impact of these areas on environmental pollution can be minimized and various problems related to the incineration of solid wastes can be prevented. Thus, it is possible to support the rapid pollution of the environment and the reduction of their negative effects on life.

It can be used in any area and everywhere by means of the low cost of the system and the system dimensions being smaller than a small freezer. This allows the large-scale waste gasification facilities to minimize the burdened costs on municipalities. In addition, it also supports the reduction of foreign dependency in order to meet its energy needs. Thus, support can be provided to increase the welfare level of the society through economic energy production.

By means of the present invention, elimination of garbage separation in countries where there is no awareness of waste separation at home, and easier separation of many raw materials that will be used for recycling in the world can be achieved with glass and metal separation drawers.
