Nomadic waste management
The task of managing waste looms large in the life of a nomad. This is especially true of managing human waste. A nomad may not have easy access to the means of disposing of waste. Yet, any laxness in the disposal of waste can quickly overwhelm a nomadic operation. Thus, the first daily task of a nomad is to act with alacrity to collect and dispose of waste.
Human waste management options: plumbing, composting, landfill
Most human waste management in America begins in rooms in buildings and vehicles variously referred to by terms like “bathroom”, or “restroom”. These rooms have a place where human waste is deposited. This is the case for nomads and non-nomads.
From that place in the room, the human waste is generally managed in one of three ways.
1. Plumbing in conjuction with a municipal treatment plant or septic system
3. Disposal in a landfill
In cities, water is mixed with the waste and the mixture is transported via pipes to a central processing area.
In more rural areas and in vehicles, water is mixed with the waste and the mixture is introduced into a septic system.
For a house, the septic system involves a septic tank followed by treatment in an underground or an overground processing area near the house known as a septic field or a sewage lagoon, respectively.
For a vehicle, the mixture is stored in a septic tank which is incorporated into the vehicle. The septic tank is periodically emptied at special facilities.
Another waste disposal system uses composting. A composting toilet typically mixes waste with some sort of absorbent material and is set up to allow the waste to begin decomposing. The composting toilet is periodically emptied into a humanure compost heap.
Another option for waste disposal involves packaging the waste. The package of waste is later picked up and transported by a truck to a landfill. Typically, this option is used for the disposing of baby diapers.
The van system for solid waste
This latter option, using a landfill, can be modified and adapted for adult use. This is a popular system used by road nomads, especially those living in vans or other vehicles that don’t have a septic tank or a composting toilet. This van method is suitable for disposal of solid waste.
For those interested in this method, I recommend videos on the subject on Bob Well’s Cheap RV Living YouTube video channel.
One simple implementation of the van system is a 5-gallon bucket lined with a plastic bag. The opening at the top of the bucket has a toilet seat attached. The nomad sits on this contraption as with any other toilet, except that he feels slightly silly. The expelled waste remains deposited in the bag; then the bag is closed and set aside. The bag with waste is later put into a container outside that is in turn emptied by municipal workers into a truck which transports the waste to a landfill.
The Hippo system
The Hippo system has two components. It uses a modified and streamlined version of the van system for solid waste disposal. It also uses the standard method of liquid waste disposal.
The Hippo system involves using Hippo Bags. Hippo bags are plastic bags that have handles. Boasting a 5-star rating with over 1,200 reviews on Amazon, you know these bags are good. When bought in bulk, each Hippo bag costs $0.15.
Hippo bags are made from a thicker type of plastic than some other bags in its 13-gallon league and have reinforced bottom seams to avoid breakage at the critical points where plastic bags tend to tear. Each bag has two handles.
Here is how the Hippo bag is used for nomadic human waste management.
1. The nomad uncovers their body in preparation to expel waste.
2. The nomad grabs the Hippo bag handles and positions the bag behind him, a handle on each side of the body.
3. The bag opening is positioned so that as solid waste exits the body it enters the bag.
4. The nomad bends their knees and proceeds to expel the waste into the Hippo bag. The body cleanup material, typically paper, is also deposited into the Hippo bag.
5. The bag is closed and set aside.
In essence, the Hippo system is the 5-gallon bucket method without the bucket and toilet seat. It is recommended, however, that a 5-gallon bucket with a gamma seal be used to store bags containing waste that are awaiting further disposal.
The long handles on the Hippo bag facilitate closing. It’s a simple matter to make a knot with the handles. Furthermore, the relatively large size of the bag compared to its contents allows for the bag to be folded over on itself, increasing its integrity.
A recommended addition to the Hippo process is to pre-fill and/or post-fill the Hippo bag with sawdust, wood shavings, or coconut husk fiber. This assists in odor control and mitigates disaster on the off chance the bag ever tears. These items are all available on Amazon.
For economy’s sake, a Hippo bag with waste can be reopened and used again over the course of several hours, or even days in an emergency or when one is low on bags, assuming some wood shavings or other absorbent material has been added. The Hippo method can make the original van system seem downright sophisticated and elegant in comparison.
The Hippo system for liquid waste
The Hippo system utilizes a standard method of liquid waste disposal.
Disposal of liquid waste involves using glass or plastic containers such as jars and bottles. Typically, the liquid is expelled into a jar. If it’s a small jar, the contents can be immediately transferred to a larger bottle.
Final disposal of liquid waste is more complicated than disposal of solid waste. In general, liquid waste must be brought to a toilet connected to municipal plumbing or connected to a septic tank and disposed of there. Disposing of liquid waste onto the ground directly is sometimes an option, preferably after diluting the liquid waste with water.
Summary of the Hippo system of disposing of human solid and liquid waste
Overall, the Hippo system works. It has notable cons:
-The method can be tricky because it requires sequestering the solid and liquid waste.
-The method is labor intensive because it requires more than just flushing waste away.
-It is not sustainable because it uses plastic bags for the solid waste.
However, assuming the nomad has a private area where to utilize the method, the Hippo system provides freedom from a dedicated bathroom. Thus, the Hippo system is an important technique in the nomadic toolbox.
Some more notes on the Hippo system
Toilets have a long history.
Scientific research indicates that squatting, as opposed to sitting, may be the more natural way to expel waste. According to one website, the ideal angle is 35 degrees; that is, the angle between the part of the back of the leg above and below the knee, with the knee as the vertex of the angle.
Best for a nomadic diet
The Hippo system works well for nomads because the nomad diet is a high fiber diet incorporating sufficient quantities of olive oil and water. This means that the consistency of the waste can be soft and is expelled quickly. The entire process from preparing the Hippo bag to closing it can take under a minute.
Not suitable for all diets
The Hippo method may not be suitable for some diets. Some diets tend to bind the waste tighter leading to harder, drier stool. This in turn can lead to a slower defecation process. Squatting, as required by the Hippo system, may become tiring.
Privacy is required for the Hippo system no less than with any other human waste management method. One can imagine utilizing the Hippo system in a car. The windows can be blocked. Or a sheet or blanket can be draped over the person. The person can place their feet on the back seat while facing towards the back of the car.
And for those ready to shell out the nomadic big bucks, there is this, a portable popup privacy portal.
Sorry. Not for me. Nosirree.
As with any new endeavor, the Hippo experience may initially seem strange, unnatural and even uncomfortable. For a child, so does the potty at first. With practice, these feelings are subject to change.
About that mason jar you were going to recycle….
Mason jars of various sizes can be used for liquid waste. A funnel and a gallon bottle, such as an empty apple cider bottle, can be used as a secondary disposal bottle.
A method for men for liquid disposal at night is a condom catheter system. This method obviates the need to get up when lying down in a cold environment. This method can get expensive. It is useful in other situations beyond cold nights, too, such as when travelling and stopping and/or finding a private location is problematic.
Why can’t the Hippo bag be used to contain liquid waste also?
It can be. One can expel both solid and liquid waste into a Hippo bag.
It’s just not recommended.
If one must use a Hippo bag in this manner, it is recommended to pre-fill and post-fill the bag with a bit of wood chips, sawdust, and/or coconut husk fiber. It is also recommended to double bag. That is, before or after hippoing, put the hippo bag inside a second outer bag.
