Definitions
- the present disclosure relates generally to the field of recycling and waste processing, including organic waste processing and byproducts thereof.
- Various systems, methods, and products relate to recycling and/or organic waste processing, including byproducts that can be obtained using methods related to processing, recycling and/or disposal of organic waste and/or green waste.
- Waste products have been filling landfills across the world for decades. In recent years, cities and countries have struggled to deal with the increased waste. Attempts at waste management have involved various programs, including recycling programs. How the waste material is treated often depends on the content and/or makeup of the waste material. For example, inorganic waste material, such as plastics, can often be transformed into other products or reused for other purposes. Similarly, some organic waste material can be turned into compost or fertilizer. Yet some organic waste material does not biodegrade very quickly and may require additional processing. For example, certain types of organic waste material may be too fibrous and therefore may take years to decompose or degrade on its own.
- a stopgap solution may be to simply cut the waste material into smaller fragments before disposal.
- these stopgap solutions are often insufficient.
- An example of these types of organic waste material includes palm fronds.
- landfills themselves cause many problems. For example, landfills produce toxic liquids that can get into groundwater and other waterways. This is particularly true for nonbiodegradable waste materials. Moreover, landfills are where many products go to decompose, yet not all of even these waste materials are exposed to oxygen and therefore are not able to decompose aerobically. Therefore, landfills produce high volumes of greenhouse gases that are emitted into the atmosphere.

For example, placing raw palm fronds into a tub grinder may not produce palm fronds that are sufficiently chopped to be used in feeds. Additionally, raw palm fronds are generally too wet to be thrown directly into a tub grinder or other grinding or chopping machine. A variety of processes can be used to put the palm fronds into a form suitable for feed before combining them with dates or other products.
- Figure 1 illustrates one method that can be used to process the raw palm fronds in combination with raw dates.
- palm fronds once palm fronds have been collected, they can be laid out in wind rows. This can allow the wind and/or ambient air to dry the palm fronds. Steps can be taken to ensure growth of mold within the palm fronds is prevented or limited.
- the wind rows can be sized such that the palm fronds are not packed too tightly or thickly, allowing fronds in the middle to dry.
- the fronds can be periodically turned over or mixed to prevent the growth of mold and to make sure that the fronds dry evenly.
- the palm fronds are arranged for drying in a manner that limits the amount of heat generated by the stacked palm fronds during the drying process.

It is understood that "hay" is a broad term and are used in its ordinary sense in this application, including, for example, to refer broadly to a dried and cut herbage which is used for fodder.
- cube is a broad term and is used in its ordinary sense in this application, including, for example, to refer broadly to a compressed feed mixture.
- References to a cubed shape can refer to a generally square or rectangular shape or to having a generally square or rectangular shaped cross section, but other shapes and cross sections are possible and contemplated, such as, for example, pellets and/or generally cylindrical shapes and/or shapes with a circular or rounded cross section.
- Cubed feed may have one or more sides or dimensions that are longer than one or more of the other sides or dimensions.
- different cubes within a batch of cubed feed may have different dimensions from other cubes within the batch. Additionally, the cubes do not necessarily have defined shapes, sides, edges or corners.
- cubes or other forms of compressed feed can be formed with a feed compressing machine, such as a cubing machine or an extruder (e.g., pelletizer).
- the machine can include a grinder that can mix and/or grind the components.
- the grinder of the feed compressing machine can be used in addition to or instead of a grinder during the process described with respect to Figure 2.

- a mixture can pass through multiple filters.
- a grinder may include a filter, and it may be desirable to pass the ground material through a second filter before it goes into the grinder or after it comes out of the grinder.
- Cubing the feed can present a variety of advantages. For example, cubed feed can be generally easier and more efficient to ship and/or store. As a further example, because cubes can be compressed when formed, they can have a greater density than loose feed allowing for more feed by mass to fit within the same volume. In some embodiments, cubes can be shipped and/or stored in large containers, such as sacks, boxes, or other containers. In some embodiments, containers can be sized to hold 1000 lbs of cubed feed. In some embodiments they can hold more or less. In some embodiments, cubes can be stored and/or shipped loosely.

- the scraps of the first feed product that remain within the mill (referred to as the "mill run") can be picked up by the base feed and mixed in with it as an additive.
- a palm frond and palm fruit mixture can be passed through a mill that had previously had wheat or other grains pass through, such as sorghum, milo, corn, etc.
- the mill run can act as an additive to the palm frond and palm fruit mixture and can add a protein component to the mixture. In some embodiments, this can provide a desired nutritional content for the resulting feed and can also serve to clean the mill run from the various components of the mill, such as tanks, flues, and/or chutes. This can help minimize and/or eliminate cleaning costs that would otherwise be incurred.
- the addition of a palm fruit to a base feed passed through the mill can help collect mill run by helping the base feed to adhere to the mill run. Additionally, as the base feed passes through the mill, the mill can help adequately mix the mill run with the base feed.
- FIG. 5A illustrates one embodiment of this method.

- Many animals may fit into multiple categories and may be able to eat feeds having a range of diameters and/or lengths.
- FIG 11 illustrates a system 1100 of pelletizing byproducts of organic waste (e.g., palm fronds). Palm fronds are collected together and stored in a palm frond storage 1104. Waste management facilities or other facilities may collect palm fronds by receiving them from government officials and/or private citizens. The fronds may include the rachis, spines, and/or one or more leaflets. The storage may include bins, piles on the ground, a trash compacter, and/or placement of palm rows or some other formation (e.g., wind rows). Preferably during the collection, the palm fronds are allowed to dry to below a maximum moisture threshold, though this is not necessary.
- the palm fronds may be sun-dried, wind dried, spin dried, tumble dried, heat dried, and/or simply allowed to air dry over time. In some cases, the palm fronds are allowed to dry for at least a day, preferably at least a week.
- the maximum moisture threshold may be less than 25% by weight, preferably less than 18% by weight, more preferably less than 15% by weight. However, depending on the arrangement of the waste disposal system, a higher moisture content may be possible.
- palm fronds are placed in a first grinder 1108 to be ground to a first length and/or diameter .
- the first grinder 1108 is outfitted with a first screen having holes with a first diameter. These holes will help ensure that only palm fronds having a first maximum length and/or diameter pass through the grinder 1108. Because palm fronds can be difficult to grind using traditional methods, grinding the palm fronds the first time at a larger first length and/or diameter before grinding them a second time at a smaller length and/or diameter has proven to be effective.
- the diameter of the holes in the first screen 1108 may be between about 1 to 3 inches, preferably around 2 inches.
- the first grinder is manufactured by Vermeer.
- the first screen may be outfitted with a baffle to help minimize the number of particles (e.g., fibers) of palm frond with a length and/or diameter greater than the first maximum length and/or diameter that pass through the first screen 1108.
- the baffles are discussed in more detail below.
- the palm fronds may be a second grinder 1112.
- the second grinder 1112 may be different from the first grinder 1108.
- the second grinder 1112 is the same as the first grinder 1112 except that the first screen has been replaced with a second screen.
- the second screen regardless if it is on the first grinder or on the second grinder, has holes having a second length and/or diameter.
- the holes in the second screen will help ensure that only palm frond particles having a second maximum length and/or diameter will pass through the second grinder 1112.
- the second screen may be outfitted with a baffle, as with the first screen, to help ensure that no particles having a length and/or diameter greater than the second maximum length and/or diameter pass through the second grinder 1112.
- the second maximum length and/or diameter may be between about 1/8 inch and about 11 ⁇ 2 inches and is preferably between about 1/4 inch and about 3/4 inch. While smaller particle sizes help in later parts of the system (e.g., with mixing, pelletizing), it also creates challenges in throughput and/or efficiency of the grinder 1112. In particular, too small of a second maximum length and/or diameter can create clogging and/or backlog problems in the disposal system, as more fully described below. In some embodiments, a suitable second maximum length and/or diameter is 1 ⁇ 2 inch. Other lengths and/or diameters are also workable.
- the first and/or second screen may be curved and/or flat but are preferably curved.
- the palm fronds that have been ground a second time to a second maximum length and/or diameter are mixed with other materials in a mixer 1116. These materials may include grains, nutritional supplements, roughening additives, fruits (e.g., dates), binding agents (e.g., canola), fill material, and/or other additives.
- the mixer 1116 may stir, shake, knead, compress, rotate, and/or blend the ingredients together to form a mixture.
- the mixture may be as described elsewhere herein.
- the mixture comprises a base feed.
- ingredients may be added according to prescribed ratios and/or percentages (e.g., by weight, by volume) described elsewhere herein. Additionally, the ingredients and their proportions may be selected in such a way as to achieve a target nutritional content. For example, the waste byproduct may be used as an animal feed for certain types of animals with particular nutritional needs. These nutritional needs may vary by animal.
- an extruder or pelletizer 1120 forms the mixture into a pellet.
- Pelletizing the waste byproduct can increase the ease of transportation, disposal, and/or storage. For byproducts that will be used for feeds, palletization can make the feed more accessible and/or appetizing to animals.
- the pelletizer 1120 may comprise a pellet mill and/or other machine. Generally, the pelletizer 1120 heats the mixture and forces it through a plate with holes having a certain hole diameter. The hole diameter determines the diameter of the pellets (e.g., Figures 10A through IOC). The hole diameter may be between about 0.1 inches and about 0.4 inches, depending on the use of the pellet.
- the hole diameter may be less than 0.1 inches or greater than 0.4 inches.
- the hole diameter is about 0.8 inches.
- the length and/or diameter of a resulting pellet may have a length and/or diameter of any of the hole diameters described above.
- the pelletizer (e.g., pellet mill) 1120 heats the mixture up to a minimum temperature in order to pass the mixture through the holes.
- the minimum temperature may depend on the formulation of the mixture that is used.
- the pelletizer uses steam to achieve the minimum temperature and/or to serve as a binding agent for the mixture. The steam may also be used to lubricate the mixture as it passes through the holes.
- some embodiments include a cooler that reduces the temperature of the plate. The cooler may also be used to cool down the mixture after it has exited the holes.
- the plate comprises a thermally insulating material (e.g., wood, plastic) that does not require a cooler for its operation.
- the plate may also comprise a layer of metal having a thickness configured to dissipate heat rapidly enough to minimize or negate the need for a cooler.
- the pelletizer cuts the mixture into particular lengths of pellets. However, in some embodiments, the mixture is allowed to freely exit the plate and break off due to its own weight, thus creating a range of pellet lengths.
- Figure 12 illustrates an example embodiment of a palm waste disposal system 1200. Though the use of palm and dates are illustrated, other waste products may be used instead and/or in addition. Embodiments illustrated by Figure 12 include preferred elements (in solid lines) and may include optional elements (in dotted lines).

- the resulting first palm particles may be sorted by a trommel screen 1216.
- the trommel screen may include a rotor to move particles from one end of the trommel screen to another. As the particles move to the end of the trommel screen 1216, some of the smaller palm grinding 's may be filtered out.
- the trommel screen 1216 may comprise a screen having openings with a maximum size smaller than the diameter of the holes in the first screens. This will permit relatively larger palm particles to pass through to a second grinding while the smaller palm particles can bypass the second grinding.
- the maximum size of the openings in the trommel screen 1216 may be comparable to the size of the holes in the second palm grinder 1228.
- the openings may be between 0.1 inches and about 0.9 inches in diameter.
- some of the resulting palm particles may later be used for palm hay 1224. The palm hay may undergo further processing and/or treatment in the system 1200. Alternatively, it may undergo different processing not shown here.
- the trommel screen 1216 may be physically situated between the first palm grinder and the second palm grinder so that the first grinder 1212, first sorting 1216, and second grinding 1228 may automatically and smoothly move palm particles from one system element to the next without significant human intervention.
- first grinder 1212, first sorting 1216, and second grinding 1228 may automatically and smoothly move palm particles from one system element to the next without significant human intervention.
- conveyor belts, rotors, and/or hoppers may be included to facilitate the movement of the palm particles.
- Some of the resulting particles can be useful for various aspects. For example, some particles may be somewhat larger and may be useful in the creation of palm hay, as described in more detail herein.

- the holes in the second screen will help ensure that only palm frond particles having a second maximum length and/or diameter pass through the second palm grinder 1228.
- the second screens may be outfitted with baffles, as with the first screens, to help ensure that no particles having a length and/or diameter greater than the second maximum length and/or diameter pass through the second grinder.
- the diameter of the holes in the second screens may be between about 1/16 inch and about 15/16 inch and is preferably between about 1/4 inch and about 3/4 inch. In some embodiments, the diameter is about 1/2 inch. Holes of 1/2 inch can help prevent clogging and/or backlog problems in the disposal system 1200 while allowing proper mixing of the palm with other additives, as more fully described below.

- the pelletizer may use steam to achieve the minimum temperature and/or to serve as a binding agent for the mixture and may include a cooler.
- the plate may comprise a thermally insulating material (e.g., wood, plastic).
- the plate may also comprise a layer of metal having a thickness configured to dissipate heat rapidly enough to minimize or negate the need for a cooler.
- the pelletizer may cut the mixture into particular lengths of pellets. In some embodiments, the mixture is allowed to freely exit the plate and break off based on gravity, thus creating a variety of pellet lengths.
- the pelletizer 1280 may optionally send the finished pellets to a bagger 1288.
- the bagger 1288 fills one or more bags with the pellets and then sends the bagged pellets to a wrapper 1292, which separates the bagged pellets into separate packages of product.
- the finished byproduct 1296 can be used as animal feed, erosion protection, bait, fill material, and/or sandbagging.
- the hopper assembly 1300 includes a receiving bin 1304, a funnel 1308, a flu 1312, a chute 1316, and an auger (not shown). Material may be fed into the receiving bin 1304. The material is guided by the funnel 1208 and through the flu 1312. The flu may have a diameter of 12 inches, 24 inches, or 36 inches. Other diameters are also possible. The auger may be 9 inches, 12 inches, or some other dimension.
- the hopper assembly 1350 also includes a flu 1312, a hopper bowl 1354, and an input chute 1358. The chute 1358 has rounded corners whereas the hopper assembly 1300 has sharp corners.
- the rounded corners of the chute 1358 are preferred over the sharp corners of the chute 1316 because the rounded corners prevent backups and blockages in the flow of material through the system 1300.
- Either hopper assembly 1300, 1350 may be used as the first hopper 1268 and/or the second hopper 1276.
- FIG 14 schematically illustrates a screen assembly 1400 that includes a screen 1404 and a baffle 1424.
- the screen 1404 includes a plurality of holes 1408 through which material generally having a length and/or diameter less than the hole diameter 1412 may pass.
- screens are generally imperfect since they sometimes allow particles having a larger length and/or diameter to pass through.
- a baffle 1424 can be attached to the screen 1404. The baffle 1424 slows the movement of particles through the holes 1408 and thus allows the grinder and/or mill to further reduce the size of the particle while it is stuck on the baffle the screen 1404 as a screen depth 1416, and the baffle 1424 has a baffle depth 1428.
- the screen depth 1416 and the baffle depth 1428 can be adjusted to achieve a target flow rate and/or particle size consistency.
- the adjustment may be made using a screw mechanism.
- specific baffle elements e.g., baffle strips
- the screen 1404 and baffle 1424 are separated by a separation distance 1420.
- the ratio of the hole diameter 1412 to the separation distance 1420 may range between about 1:4 to about 3: 1. In some embodiments, the ratio is between about 1:2 to about 2: 1, preferably about 1: 1. In certain configurations, a ratio of 1: 1 strikes a suitable balance between rate of flow of material and consistency of the particle size.
- certain embodiments of the system 1200 have been found to work with particular efficiency and speed of grinding palm fronds.
- the baffle 1424 may include one or more baffle strips (not shown in Figure 14). Each of the one or more baffle strips may be welded on the screen (e.g., the separation distance 1420 would be zero).
- the baffle strips can allow for using a larger hole size in the screen while maintaining a similar quality in the grinding of the palm.
- the baffle strips can be configured, for example, to slow the flow of palm particles therethrough. This slowing may be between about 1 ms and 500 ms, relative to a screen of the same hole size without the baffle strips. The slowing may be between 25 ms and 1200 ms in some embodiments where palm particles may need more time to be ground (e.g., when the palm has a higher moisture content).
- the slowing may be between 45 ms and 2500 ms.
- the baffle elements may allow for grinding palm that has a higher moisture content.
- the higher moisture content palm may have greater than 15% moisture content by weight, greater than 30% moisture content by weight, greater than 50% moisture content by weight, and/or greater than 60% moisture content by weight.
- the baffle may include a piece (e.g., strip) of metal welded across the length of the back of the screen, so that the baffle covers a portion of one or more holes 1408. In some embodiments, the baffle does not cover a center of the hole 1408.
- the baffle strips may cover a certain percentage of the area of one or more of the plurality of holes 1408. For example, the baffle may cover between about 5% and 70% of each hole of at least one or more of the plurality of holes 1408. In some embodiments, the baffle may cover between about 10% and 55% of each hole of at least one or more of the plurality of holes 1408.
- the baffle strips cover between about 15% and 45% of each hole of at least one or more of the plurality of holes 1408.
- the baffle strips may be welded parallel to an orientation of a row of adjacent holes such that the baffles trip may be able to cover approximately the same amount of each adjacent hole.
- the baffle strips may be disposed on an interior side (e.g., the grinding side) of the screens 1416. Additionally or alternatively, the baffle strips may be disposed on an exterior side (e.g., the exit side) of the screens 1416. In some embodiments, the baffles may be alternated on the interior side and the exterior side of the screens 1416.
- the baffles may be associated with screens on one or more of the first and second grinders disclosed herein (e.g., the first palm grinder 1212 and/or the second palm grinder 1228 of Figure 12).
- other grinders and/or mills e.g. the hammer mill 1272
- One or more of the baffle strips may be disposed parallel to one another. This may be true even in embodiments where not all of the baffle strips are disposed on the same side of the screen 1416.
- the baffles 1424 (e.g., the baffle pieces) may provide added strength and durability to the screens 1416.
- the baffles 1424 may comprise a metal (e.g., iron, aluminum, steel, etc.).
- a baffle may be a screen-like attachment to a screen configured to ensure that the palm fronds are ground to a proper length/diameter before being discharged from the grinder.
- the baffle may have holes itself.
- the baffle holes may have a different size hole as the screen to which it is attached.
- the holes may be larger or smaller than the holes of the screen.
- the baffle is a second "screen" identical to the screen to which the baffle is attached. In this way the baffle can provide some of the benefits described herein with respect to the baffles.
