Description
TECHNICAL FIELD

The present invention relates generally to waste treatment, and particularly to a method and system for organic waste treatment.


BACKGROUND

Large amounts of organic waste are generated annually from agricultural plantations, animal farms, mills, food processing plants and industrial plants. The amount of organic waste generated has been increasing each year as the agro-food industries expand. Consequently, the disposal and proper utilization of these wastes has been a major concern in recent years.


Further, organic waste generated such as industrial waste, animal and plant by-products, and faeces are a major cause of environmental pollution. Conventionally, different methods are available for safe disposal of these organic waste and for conversion of the waste into animal feed. Examples of popular conventional methods are landfilling and incineration. Landfills require extensive areas and are both unsanitary as well as require higher management cost. Further, landfills create problems such as the leaching of harmful chemicals into the soil, contaminating ground water, and causing loss of essential nutrients which are present into the soil. Incineration is also expensive, and creates environmental problems.


Further, feeding the treated waste generated out of the landfilling and incineration to animals without further processing may cause various health problems for the animals. Also, the resultant product from these treatment methods doesn't serve to provide satisfactory fertilizer effect.


In the past, the best solutions proposed to overcome such problems is to utilize microorganisms such as different species of larvae of earthworms and/or house flies, to efficiently treat the organic waste to produce quality fertilizers and animal feed. The fertilizers produced using such bio-conversion/biological treatment methods are usually found to have better fertilizer effects, which in turn improves overall plant growth and crop yields. Although, several biological treatment methods were proposed in the past for treating the organic waste to address the problem of organic waste disposal and conversion of organic waste into harmless and more value-added products. Most of such existing solutions require lot of time and human efforts as most of the existing systems are manual systems, and require huge management cost incurred after maintenance of such systems and human force working on such systems.


Further, as the existing biological treatment methods and systems are handled manually and are labour intensive, thus they suffer scalability issues, especially when there is a huge demand for the fertilizers and animal feed. Existing solutions or designs are box shaped and are handled by using conveyor belts and long shelves. Those shelves are then connected to motors and conveyors that consume lot of electricity to operate through conversion cycles. When the demand is huge, then it is certain that such existing solutions would not be cost effective. Further, to meet the huge demand or mass production of the fertilizers and animal feed out of the organic waste such solutions will require significant design changes which is practically impossible to implement.


A number of prior art discloses various methods and systems for safe disposal of organic waste or conversion of organic waste into fertilizers or animal feed or the like. For example, U.S. Pat. No. 6,780,637 describes a method and system for efficiently bio-converting putrescent wastes to a more usable form. U.S. Pat. No. '673 discloses a bio-conversion unit for facilitating bio-conversion of waste material. The bio-conversion unit includes a rounded container with two small ramps (spiraling up from bottom to top) configured inside of the container.


U.S. Pat. No. 5,082,486 teaches a method for the production of organic compost. As disclosed, the method discloses shredding the refuse, adding water to saturation, adding earthworms, keeping the water content at more than 80% during at least 30 days, keeping the mixture at a temperature from 0-54° C. and with a moisture of at least 45% during more than 4 months.


U.S. Pat. No. 6,001,146 describes about a device and a method for the continuous treatment of putrescent waste in which the waste is eaten by fly larvae. As disclosed in the patent, the device comprises a conveyor belt, a means to distribute the waste, a means for depositing fly larvae or fly larvae eggs onto the waste, a means for removing fly larvae from the waste and from the conveyor belt, and a means for removing the waste from the conveyor belt.


WO2008134865 describes a system for processing organic waste using insect larvae. According to the application, the system includes multiple substantially flat reaction vessels stacked one on top of the other, to form a processing block. Each of the reaction vessels in the processing block is configured to hold quantity of organic waste. Each of the reaction vessels is separated from the reaction vessel above by an air space and the processing block is contained in a plant enclosure having side walls. At least one of the side walls of the plant enclosure is positioned adjacent the processing block such that the plenum wall is adjacent one of the side edges of the reaction vessels. The plenum wall has openings which communicate with the air spaces. The openings are positioned on the plenum wall such that the openings are immediately adjacent the air spaces. The system further includes an air circulation system for circulating air through the air spaces by passing air through the openings in the plenum wall and a feeder system for loading raw organic waste onto the reaction vessels. The reaction vessels preferably being an elongated belt, which consists of an elongated flexible web suspended between a pair of rollers.


In the light of foregoing, and although the prior arts exists in the space, inventor still feels there is sufficient space for an improved system and method for treatment of organic waste that overcomes, or at least ameliorates the disadvantages described above.

Thus, these terms are not necessarily intended to indicate temporal or other prioritization of such elements.


Unlike conventional systems and methods discussed above, the present invention discloses a bio-conversion method that uses a certain species of microorganisms, particularly larvae of Black Soldier Fly Larvae (BSFL) (Hermetia illucens) to effectively convert organic waste into harmless and more value-added products such as fertilizers and animal feed. The organic waste may include but not limited to industrial waste, animal and plant by-products, and faeces. The black soldier fly's developmental takes a specific period of time, within which its transitions take from an egg to a fully functioning adult. The specific period of time for the black soldier fly to get fully developed can take between 37-41 days, and out of these 41 possible days, approximately 14 days are spent decomposing organic wastes (during these 14 days, larvae of Black Soldier Fly are active on decomposing organic waste). Once these first 14 days have passed, the BSFL ceases to process the organic waste and instead migrates to a dry place so that it can begin to pupate. In an experiment conducted, where 5000 BSFLs were placed into a container with 10 kg of organic wastes contained therein. The BSFLs managed to decompose more than 80% of the organic waste within a period of 5 days, which resulted in a reduced volume of the organic waste by 42% and weight by 70%. In comparison to the efficiency of house fly larvae and earthworm larvae widely used in the conventional treatment methods, the BSFLs are found to be more efficient in achieving the desired high value products such as fertilizers and animal feed. In contrast to the earthworm larvae and house fly larvae used in conventional systems, the BSFLs spend much longer time decomposing the organic waste.


The various features and embodiments of the organic waste treatment system and method are better explained in conjunction with FIGS. 1-5.


Referring to accompanying figures, the system 100 includes a tower preferably cylindrical or circular in shape. The tower includes a first section 104, and a second section 106 operationally engaged to the first section 104. The second section 106 of the tower is operationally engaged to the first section 104 using a shaft 106b configured thereon. The shaft 106b includes an end that connects to a motor 109 in order for the motor 109 to rotate the second section 106 within the first section 104.

The first section 104 and the second section 106 both includes a plurality of floors collectively referred as 104a, and 106a respectively as shown in the FIGS. 3A-3B. According to an embodiment, the number of floors 104a of the first section 104 is equal to the number of floors 106a of the second section 106. According to another embodiment, the number of floors 104a of the first section 104 may not be equal to the number of floors 106a of the second section 106. The floors of the first section 104 of the tower includes a receiving slot 104b for receiving the shaft 106b of the second section 106 therein to facilitate rotation of the second section 106 within the first section 104. The rotation of the second section 106 within the first section 104 may be clockwise or anticlockwise.


Each of the floors 104a of the first section 104 is hollow and configured to receive and facilitate bio-conversion of the organic waste into one or more value-added products such as fertilizers and animal feed using one or more microorganisms preferably larvae of Black Soldier Fly Larvae (BSFL). Further, each of the floors 104a of the first section 104 is configured to serve a pathway for corresponding floors 106a (which are non-hollow) of the second section 106 when the second section 106 is operated to rotate within the first section 104 by using the motor 109. The floors 104a of the first section 104 are open at two ends in order to facilitate the second section 104 (having floors with non-open ends) to rotate within the first section 104 in order to eject or harvest the value added products out of the first section 104 after the treatment/bio-conversion process ends.


According to the embodiment, the system 100 further includes a support structure configured to support the tower. The support structure includes one or more rings 102a complementing to the shape of the tower. According to an embodiment, each of the rings 102a are interconnected to form a disposal space for receiving the tower. According to some other embodiment, the disposal space for receiving the tower may be formed using a one piece ring in the form of a continuous spiral. According to some other embodiment, the disposal space for receiving the tower may be formed by utilizing a cylindrical container or just a base that can hold the tower. The support structure further includes legs 102b that help the support structure to stand upright holding the tower. Although, in the example illustrations, three legs are shown, it is possible to have any numbers of legs 102b as long as the support structure holding the tower is able to stand upright in a stable manner.


According to the embodiment, the system 100 further includes at least one first passageway, such as passageway 108 with a plurality of nozzles 108a. As shown, the passageway 108 is mountable on the side of the support structure holding the tower for selectively channelling or pumping the organic waste specifically pre-processed or blended form of organic waste, and the one or more species of microorganisms, preferably 5 days old larvae (5 DoL) of Black Soldier Fly (BSF) into selected floors of the first section 104 for them to enable bio-conversion process as shown in the FIG. 4. The nozzles 108a of the passageway 108 are independently controllable using one or more valves (not shown).


According to the embodiment, the system 100 further includes at least one second passageway such as passageway 107a with a plurality of nozzles 107c. The passageway 107a is mountable on the side of the support structure for channelling air into the floors of the first section 104. According to the embodiment, the system 100 further includes at least one third passageway such as a passageway 107b with a plurality of nozzles 107d. The third passageway 107b is mountable on the side of the support structure for channelling air out of the floors of the first section 104. Injecting continuous air into and out of the floors of the first section 104, where the bio conversion process happens facilitates in maintaining adequate moisture level which is required for the larvae of Black Soldier Fly (BSF) to act upon the organic waste. According to the embodiment, the nozzles 107c of the passageway 107a and the nozzles 107d of the passageway 107b are provided with a filter to prevent the microorganisms, i.e BSFL, and the organic waste to enter therein.


According to the embodiment, the system 100 further includes a collection tray 110 adapted for collecting the value added products ejected out of the tower after the treatment/bio-conversion process ends, and a screw conveyor 112 operationally connected to another motor 114. The screw conveyor 112 is configured to receive the value added products from the collection tray 110 and transfer the collected value added products for further processing into a separator (not shown) through an outlet 116.


According to the embodiment, internal walls of the floors 104a of the first section 104 and outer wall of the shaft 106b are coated with hydrophobic coating for ease of cleaning, and harvesting of the value added products from the first section 104 of the tower.


Although, in the forgoing description it is explained that organic waste is channelled or pumped into the floors 104a of the first section 104 of the tower, it should be understood that, the term “organic waste” here refers to pre-processed organic waste, before the resultant organic waste is pumped into the floors 104a of the first section 104 of the tower. The pre-processing essentially includes following steps:

    • (a) shredding the organic waste into tiny chunks preferably smaller than 5 mm such that BSFLs can efficiently consume or act upon the organic waste.
    • (b) sorting and transferring the shredded waste to one or more storage tanks based on food types.
    • (c) adding a chemical agent to the organic waste stored in the storage tanks to maintain safety and freshness of the stored organic waste.
    • (d) transferring different types of stored organic waste in different ratios from different tanks into a mixer for blending.
    • (e) adding water and identifying the correct moisture amount for the organic waste during the mixing/blending process. The identification of moisture amount is facilitated by a moisture level sensor. Adequate moisture level at this stage is maintained since BSFLs can treat organic waste that has 80% or above moisture level.
    • (f) storing, the blended organic waste resulted out of the mixing process/blending process for inputting into the floors 104a of the first section 104 of the tower. For the purpose of this application, the resultant at this step will still be termed as “organic waste”.


In operation, once the blended organic waste (step (f)) or organic waste is ready for distribution to the floors 104a of the first section 104, some pumping system known in the art can deployed to pump/channel the organic waste into the selected floors 104a of the first section 104 via the passageway 108. The nozzles 108a of the passageway 108 are operationally coupled to each of the floors 104a of the first section 104 and individually controllable using valves, so user can selectively pump the organic waste into the selected floors 104a of the first section 104 for bio-conversion process.


Likewise, once the organic waste is pumped into the selected floors 104a of the first section 104, the user can then selectively pump the 5 days old larvae of BSF into the selected floors 104a of the first section 104 using the pumping system via the passageway 108. Although, the embodiments of present invention is describes use of 5 days old BSFLs, it should be understood that within the scope of the scope of present invention, even larvae of 4 days old, 6 days old, 7 days old etc. can also be used, it is just that, 5 days old larvae is capable of yielding better results.


Further to facilitate the bio-conversion process, the user can pump/channel in and out the air to and from the selected floors 104a of the first section 104 using the passageways 107a, 107b in order to maintain adequate level of moisture inside the floors 104a of the first section 104 where bio-conversion takes place.


Next, in the bio-conversion process, the channelled/pumped microorganisms and the organic waste in the first section of the tower are allowed to remain therein for a specific period of time to convert the pre-processed organic waste to value added products such as fertilizers and animal feed. The specific period of time for which the organic waste and BSFLs are allowed to remain under the bio conversion process is preferably but not limited to 14 days (or any time by which the larvae ceases their decomposing capability)


Next, once the bio conversion process ends, the harvesting of the value added products and the microorganism out of the first section 104 takes place. The harvesting is facilitated by rotation of the floors 106b of the second section 106 of the tower within the first section 104. The rotation of the second section 106 within the first section 104, dumps all of the bio converted value added products into the collection tray 110, which is then transferred to a separator for further processing using a screw conveyor 112. The screw conveyor 112 is connected to a motor 114 which rotates the conveyor 112 to transfer the conveyor 112 to the separator using an outlet 116 for separating the larvae out and to obtain the fertilizers and animal feed.


It should be noted that, the organic waste treatment system and associated components thereof described above in the FIGS. 1-5 may be made of any suitable material known in the art, and be made in different sizes that may make the presented invention realization in real scenario.


The preceding description has been presented with reference to various embodiments. Persons skilled in the art and technology to which this application pertains will appreciate that alterations and changes in the described structures and methods of operation can be practiced without meaningfully departing from the principle, spirit and scope of the present invention.
