DESCRIPTION OF EMBODIMENTS
[0268] Disclosed is an example embodiment of a system of waste management and processing system, in particular, of a compost generation system.
[0269] The compostable stream is also further processed by decontamination of non compostable material, where the contaminants are removed, identified and weighed to be reported back to the individual waste source business, or household for education, improvement and possible billing of a ‘contamination levy’ depending on the level of contamination in each bin. Once the compostable material has been decontaminated of non compostable material, it is shredded to reduce bulk load and placed in a dewatering system to remove excess liquid so as to control the moisture content, and temperature of the compostable waste processing method 42. A bulker can then be added with the compostable waste to achieve satisfactory aeration and create an optimum carbon and nitrogen ratio in the composting environment. Examples of bulker may include wood chip, biochar or a synthetic bulker. The compostable waste is transferred into a composting unit 40 for a period of 10 to 16 days. The compostable waste inside the composting unit 40 is mixed and agitated periodically to promote biodegradation of the compostable waste into compost material. In a preferred form, the waste inside the composting unit is rotated at least one revolution every one hour. After the revolution, the waste then remains stationery until the next cycle or revolution occurs. For example, as illustrated in
[0270]
[0271] Preferably, the desired temperature level for cured compost is between 28° C. to 35° C.
[0272] In an alternative embodiment, the desired temperature level in the aeration crate 26, 41 is between 35° C. to 37° C.
[0273] In yet another preferred embodiment, the aeration crate may be a mechanized aeration crate 26, 41 configured with mechanized means, for example fans, tubes or like.
[0274] Alternatively, mechanized aeration crate 26, 41 may include heating or cooling facilities, for example temperature control elements, heat exchangers or like.
[0275] Preferably, the mechanized aeration crate 26, 41 may include hydration control facilities.
[0276] With reference to
[0277]
[0278] The compost material from the composting unit is transferred into a mixer 51. The compost material can be inoculated with beneficial microbiology insider the mixer 51. For example, the beneficial microbiology may comprise of bacteria, fungi, protozoa or a combination thereof. The inoculation process continues until a desired moisture content level is achieved (e.g. 45% to 55% by weight). Once the compost material has reached its optimum moisture content, the compost material exits the mixer via a chute 52 and is transferred to an aeration crate for curing and storage.
[0279]
System of Full Recycle
[0280]
[0281] The recyclable materials 524 may be recycled into other useful products. For example, plastic wastes may be recycled into plastic products such as aeration crates, pots, waste collection bins, building products and polyester threads. Paper and cardboard wastes may be recycled into packaging products such as takeaway containers and coffee cups. Glass wastes may be recycled into glass products such as bench tops, artworks or aggregate for earthworks or road base. Polystyrene wastes may be recycled into polystyrene products such as surfboards and picture frames. A person skilled in the art would understand that the above examples are not exhaustive and other useful products may result especially through advances in recycling technology.

[0284]
Wastewater Treatment Procedure Process
Packaging Waste Liquid
[0285] Packaging waste bins will be discharged to the Packaging Waste Sorting Bench to enable manual sorting based on material.
[0286] Drainage from the packaging waste, combined with the spent wash water from washing of the packaging waste bins, will drain under gravity or be pumped to a bioreactor.
[0287] This wastewater stream will be relatively dilute, with pollutants primarily comprising residual beverages from the packaging.
Food Waste Liquid
[0288] Food waste bins will be discharged to the food waste sorting bench to enable manual decontamination.
[0289] Free drainage from the food waste on the bench, combined with spent wash water from washing of the food waste bins, will drain, or be pumped to the bioreactor.
Food Waste Dewatering Liquid
[0290] The decontaminated food waste will be concentrated within a food waste dewatering unit to reduce the moisture content of the feed to any anaerobic digestion process, or the aerobic composting process.
[0291] Drainage from the dewatering unit will be directed to the bioreactor.
Bioreactor
[0292] The bioreactor may comprise a single intermediate bulk container (IBC) of approximately 1000 L capacity but may be expanded to additional multiple IBCs operating in series or larger containers depending on the pollutant loads received.
[0293] The bioreactor will be aerated intermittently (approximately 30 minutes on/30 minutes off) to cycle the unit between aerobic and anoxic conditions to facilitate treatment of the organic and nitrogen-rich pollutants.
[0294] Once per day or at other suitable intervals depending on pollutants present, aeration will be suspended to enable the biomass formed within the treatment process to settle to the base of the IBC.
Filtration/Disinfection
[0295] Once settled, the clarified effluent from in the upper levels of the IBC will be transferred through a cartridge filter and UV disinfection unit for further treatment, then stored in a dedicated recycled water storage tank.
[0296] Scum, oils and grease will be excluded from the recycled water stream by a baffle within the bioreactor.
[0297] The cartridge filters will capture residual suspended solids from the bioreactor effluent and will be manually cleaned as required.
[0298] The UV disinfection unit will provide pathogen kill to ensure the recycled water is suitable for use in bin washing.
Compost Tea Generation
[0299] Once per day, a small portion of the settled biomass may be manually drained to a separate IBC for compost tea generation. An inoculum will be added, and the IBC intermittently aerated to promote stabilisation of the biomass and generation of the product. The compost tea will be intermittently decanted for off-site use or added to the compost product generated by aerobic composting process to increase its moisture content.
Recycled Water
[0300] Sodium hypochlorite or other agent with similar effect may be introduced to the recycled water storage tank if required to maintain the quality of the water during storage. Recycled water will be drawn from the storage tank to undertake bin washing as a part of routine daily operations. Given the limited import of liquids to the site within the bins, and the export of moisture with the compost product or compost tea, it is not anticipated that substantial excess recycled water will be generated by the process. However, should this occur, excess recycled water would be transferred to an STP (sewerage treatment plant) or irrigation.

[0304]
[0305] Other configurations are possible depending on the amount and type of waste, and the cost and distance involved in transporting the various waste streams to either disposal or processing/recycling. A significant feature of this system is that facilities can have all the operations and associated equipment in one location, or parts of the system and associated equipment in different locations. The system includes an algorithm which optimises the value derived from each waste stream while limiting transport and other costs. The algorithm is based on the value of waste streams by volume pre and post sorting, compaction transport. Proximity to customers or users of the end products may also be factored in to prioritise relationships with customers and closed-loop local food growing and product manufacturing.

“On Site” Waste Decontamination, Separation and Bundling
[0307] One embodiment of the onsite waste decontamination, separation and bundling system is called, for sake of convenience, a decontamination module as illustrated in
[0308] For example, a decontamination module can be located in the basement or service/maintenance area of a shopping centre, or building and process all of the waste from the various food businesses within it.
[0309] The advantage of a decontamination module is that uncompacted waste produced by Customers waste streams can be transported to the decontamination module within individual bins individually tagged to the customer without the use of heavy equipment such as trucks. Instead, compostable and non compostable waste streams in their uncompacted state reach the decontamination module by walking, elevators, trolleys, buggies, vans, utilities or other light commercial vehicles etc. The decontamination module decontaminates and separates the waste into various streams, which can then be effectively consolidated.
[0310] For example:
a) glass is separated from other materials in the decontamination module, then crushed and placed into containers for easy transport. This greatly reduces the volume of glass to be transported.
b) Paper and cardboard are separated from other materials in the decontamination module, then compacted and bundled for ease of transport, e.g. on pallets. This greatly reduces the volume of paper and cardboard to be transported.
c) Similarly with plastics and metals
d) Oils can be separated and placed in large containers for ease of transport
[0311] The advantage of the system is that waste is separated into useful commodities and compacted BEFORE it is transported by heavy vehicle. A further advantage of this system is that waste to be transported from the decontamination module is able to be handled with a forklift and a normal truck, rather than a compactor truck. Overall, the system allows compacted waste to be transported without destroying its usefulness, and allows collection of materials directly from the decontamination module by a third party, or for transport to the composting facility without specialist equipment.
[0312] A final feature of the decontamination module is that is it small and therefore often able to be located within existing buildings, is clean, hygienic and produces no foul odours.
In Use
[0313] With reference to
[0314] The non compostable waste stream is further processed into recyclable material and non-recyclable material. The recyclable material is packaged for sale and distributed to third party users or processed into commodities of higher value. Any non-recyclable material is transferred to a landfill, waste facility or energy facility.
[0315] The compostable waste stream is also further processed by decontamination, shredding and dewatering of the compostable waste. A carbon based bulker material such as woodchip or biochar may be added to the compostable waste for aeration and a balanced level of carbon and nitrogen ratio. The compostable waste is then transferred to a composting unit to undergo decomposition and pasteurisation for a period of 10 to 16 days. This process will turn the compostable waste into compost material. Once the compost material exits from the composting unit, the compost material may be transferred to a storage device. The compost material is then transferred to a mixer where the compost material is inoculated with beneficial microbiology to increase the quality of the compost material. The types of beneficial microbiology may comprise of bacteria, fungi, protozoa or a combination thereof. The inoculation process continues until a desired moisture content level is achieved. Preferably, the desired moisture content level is 45% to 55% by weight. Once the compost material has reached its desired moisture content level, the compost material is transferred to an aeration crate for curing and storage. Preferably, the aeration crate is cylindrical and is one cubic metre in volume. This volume size is preferred for ease of transport within the facility. However, the aeration crate is not limited to any size or shape.
[0316] Curing takes place in the aeration crate where the temperature and moisture level of the compost material is regularly monitored. If the temperature is too high, the compost material inside the aeration crate is agitated (by mixing or turning the compost material) to replenish the oxygen level of the compost material. If the moisture level is too low, the compost material inside the aeration crate will be returned to the mixer so that moisture may be added to the compost material. The aeration crates may be stacked on top of each other, within a shelving system, and stored within the facility. Once the curing process ends, the composted product is tested to meet quality assurance standards such as AS4454 and EPA and other government regulations
[0317] Once the appropriate standards are achieved the compost material is packaged and sold commercially to market
ALTERNATIVE EMBODIMENT TWO
[0318] The waste management and processing system has developed around the idea of a decontamination module which is a locally situated facility which does the ‘front end’ waste processing prior to transporting compostable waste and some other waste streams (plastics etc.) to the Central Processing Facility for further processing, while other wastes can be bundled and collected straight from the decontamination module for sale to third parties.
Sorting, Data Collection and Reporting System
[0319] The waste management and processing system begins ‘in house’ at the source of the waste (e.g. the restaurant, café, hotel, club, event, household etc.)
[0320] The Customer is provided with a sorting, data collection (acquisition) and reporting system which facilitates the separation of food waste from other waste streams at source. The bin features are described in more detail in
[0321] These bins are then collected and placed on a manual sorting bench using a bin lifting device, or conveyor belt for manual, mechanized or robotic sorting.
Compostable Stream
[0322] The compostable stream is checked for contamination and any non-compostable materials (e.g. packaging waste) removed and placed into the appropriate stream. Uncontaminated compostable waste, now a useful commodity, may be transported to third parties or processed further as described below.
Non-Compostable Stream
[0323] The non-compostable stream is checked for contamination (e.g. food in containers) and is decontaminated (e.g. by washing contaminated containers).
[0324] Uncontaminated non-compostable materials such as plastics, glass, metals and paper/cardboard are separated into various streams for further processing and/or bundling/sale. Separation can be done by hand, robotically, or by various other methods (e.g. magnets to separate the metals, fans to separate the lighter materials).
[0325] Uncontaminated non-compostable separated waste, now a valuable commodity, is now compacted and/or bundled for ease of transport. For example, glass may be crushed, metal and paper/cardboard may be compacted and bundled. Separated waste streams may be transported to third parties or processed further as described below.
Data Collection
[0326] Data is collected on the waste sourced from each individual Customer by means of weighing devices, cameras and scanners which report to a computerised system
[0327] Artificial Intelligence/Machine Learning may be used to identify and sort waste and gather data on the types of waste coming from each bin/Customer
[0328] The system identifies and collates information about the amount and type of waste and contamination sourced from each Customer.
[0329] The data is used for a variety of purposes including education of the individual Customer to help improve their purchasing, sorting and other processes, charging fees to the customer according to the materials removed and the contamination level, business planning, and selling ‘meta data’ (i.e. collated data form multiple customers) to government, commercial and other third parties.
Processing of Compostable Waste Including Removal of Pathogens and Inoculation
[0330] Once the waste materials have been sorted into compostable and non-compostable waste, the compostable waste is decontaminated, shredded and dewatered in preparation of the composting process. Subsequent to decontaminating, shredding and dewatering of the compo stable waste, depending on the moisture level, bulking agent (such as wood chips or dry grass) may be added into the compostable waste to absorb excess moisture and increase air flow in the compostable waste. Preferably, the moisture content is between 40% to 50% of total mass. The aerobic composting process commences when the compostable waste is placed into the aerobic composting unit. An example of a composting unit is described in the above international application (PCT/NZ01/00171). For example, a composting unit will have a stationary composting chamber with an inlet and outlet end. The inside of the chamber may contain a series of discrete arms which can mix and agitate composting materials placed in the inlet and transport the composting materials to the outlet at the other end of the chamber. Depending on the temperature, moisture level and stage of decomposition of the compostable waste material, the composting unit may mix the composting material periodically (for example, the composting unit may churn the composting material within the chamber once per hour). After mixing, the composting material is not agitated until the next cycle of mixing. Although mixing the composting material may not be necessary, mixing the composting material may speed up the composting process and thus may provide commercial benefits to do so.
[0331] When the composting material rests inside the chamber during the aerobic composting process, heat is naturally generated as a by-product of the microbial breakdown of compostable material. The amount of heat produced depends on the size of the composting material, moisture content, aeration carbon to nitrogen ratio. Typically, the temperature inside the chamber should range between 55-65° C., which can last for 10 to 16 days depending on the volume of the composting material and composition of the ingredients. The heat produced in the aerobic composting process is essential for destroying thermosensitive pathogens, fly larvae, and weed seeds. Generally, the temperature of the composting material is kept below 65° C. to ensure beneficial microbes are not destroyed in the composting process. However, if the temperature of the composting material gets too hot, mixing or aerating the composting material will assist in dissipating the heat.
[0332] When the composting material begins to cool, agitating the composting material (such as turning or mixing) will result in a new temperature peak due to the replenished oxygen supply and the exposure of compostable matter that has not been thoroughly decomposed. However, when temperature drops and is not restored by agitating the composting mixture, the composting material enters the “curing” or maturation stage.
[0333] The curing stage occurs after the composting material is expelled from composting unit. At the curing stage, the temperature of the compost material is close to ambient temperature (for example, 25 to 35° C.) and chemical reactions continue to occur to promote the stability of the remaining compostable matter thus enabling it to be suitable for use with plants.
[0334] Generally, the composting process within the composting unit will take 10 to 16 days until the composting material is removed from the chamber and placed in a storage hopper and/or aeration crates where the curing stage takes place. Oxygen is necessary for the metabolism and respiration of aerobic microorganisms, and for oxidising compostable molecules present in the composting material. Therefore, maintaining an aerobic environment is necessary and the composting material may still require mixing in the aeration crates to maintain an optimum level of oxygen.
[0335] In order to maintain a balance level of moisture, heat and good air circulation, the size of the aeration crate may be in the range of 900 mm to 1500 mm in one dimension at least. In a particular preferred form, the width dimension is 1200 mm. In a particular preferred form, the height of the aeration crate is 1200 mm. In a preferred version, the aeration crate may be in the form of a cylinder of approximately 1200 mm diameter. In a particular preferred form, the aeration crate is approximately one cubic metre in volume. The walls of the crate may be of any material or construction which allows aeration. For example, the walls may be made of a mesh material having apertures. In the preferred form the apertures may be circular apertures of diameter in the 5-15 mm range. In most operations, the size of one cubic metre in volume is preferred for ease of transporting the aeration crates within the facility from storage racks where the aeration crates are stored in stacks and transported to a desired place by forklift trucks. In a version suitable for larger scale plants, aeration takes place in a ‘wall’ made of any material which allows aeration and is in the range of 900-1500 mm thick. An example of a wall is illustrated in
[0336] Probes may be inserted into the aeration crates to continually monitor the moisture, temperature and oxygen levels of the composting material. Tubes which carry warm/cold air may be added to control temperature and improve aeration. Hoses or misters may be added to control the moisture level.
[0337] Throughout the composting process, various parameters such as the carbon to nitrogen ratio, composting temperature, pH of the finished compost, moisture content and the presence of potential pathogens (e.g. coliform bacteria) are monitored to assess the quality and stability of the compost, and where the compost is outside the parameters, adjustments are made to bring the parameters into a suitable range.
Inoculation
[0338] Inoculating beneficial microbiology into composting material can speed up the growth of microorganisms in the composting material and improve the quality of the compost. In this invention, specific types of inoculants may be added into the composting material so that a particular type of compost is produced. For example, fish hydrolytes or other substances of similar effect may be added to produce fungal-dominant soils for specific types of plants (such as fruit trees) which prefer soil dominated with fungi. In another example, molasses or other substances of similar effect may be added into the composting material to produce bacteria-dominant soils suitable for specific types of plants (such as salads and certain vegetables) which prefer soil dominated with bacteria. By providing the correct type of soil to plants, it will encourage the plants to grow in the preferred condition.
Further Processing of Non-Compostable Waste Streams
[0339] Non-Compostable waste streams may be sold directly to third parties but may also be processed into higher value goods. For example, plastics may be used to produce fuel/or oil, or extruded into various forms including building materials. PET may be used to manufacture clothing. Polystyrene may be processed to produce activated carbon, or products such as surfboards, picture frames etc.
[0340] It is a feature of this invention that the above processes do not necessarily take place in one location. One of the significant challenges of waste management is that waste is a high-volume, low value product, and it is therefore uneconomic to transport. Overwhelmingly, the current solution to this is to compact waste in a compactor truck for transport. As mentioned above, once compacted, the opportunity for gathering data on the waste to an individual source, and for separating the waste streams into useful products, is lost. This invention takes a different approach to the challenge of transporting waste, which allows it to separate and process waste into useful products in small facilities which can be co-located with the source of the waste.
[0341] The above describes only some embodiments of the present invention and modifications, obvious to those skilled in the art, can be made thereto without departing from the scope of the present invention.
INDUSTRIAL APPLICABILITY
[0342] Embodiments of the present invention may be applied to transport and process waste material. In particular forms some processing may be done prior to transport. In other forms, additional processing may be done at a location separate from the initial point of pick up of the waste material. In particular forms, valuable and usable product is produced by the processing.
