Sustainable toilet technology

Enclosed Long Term Composting

Nothing less than revolutionary new thinking about toilets:

Inadequate toilet facilities -- a real killer

• 2.5 billion people worldwide lack access to toilets !

• 5 million people die each year from diarrhea and dehydration.

• More people die from diarrhea than from both HIV and malaria together.

• Every 15th second a child dies of diarrhea related disease.

Safe toilets -- the missing link• Every DAY, around 10,000 people die because they

drink water that has been polluted by unprocessed toilet waste.

• In India 3 out of 4 have NO toilet. Others may have toilets, yet feces may still leach out to infect the available drinking water.

• We may think this is only a problem in India, China or Africa but it is NOT…

Sewage making people sick

• In London, for days after a rain the Thames river has raw sewage gushing into it

• In vacation resorts around the world, sewage infects the beaches

• Sewage is by far the largest polluter of oceans and estuaries(here seen as fish food)

Sewage treatment is out of date

• “Sewage treatment” mainly consists of attempts to separate the waste from the drinking water which no one can do at a reasonable cost.

• The result is just less polluted sewage effluent and a large amount of toxic sludge which no one knows what to do with … all that at an enormous cost !

A costly and perilous deception

• Since neither the sewage industry nor governments know what to to with toxic sludge, they simply re-name it

• They now call it “BIO-SOLIDS” and spread it on food producing land … it is poisoning and it stinks

This is a problem everywhere!

• The flush toilet was invented some 200 years ago to discretely send the queens body-waste out of Windsor castle, that’s all it was meant to do … getting rid it, out of sight, out of mind …

• Today this practice is the root of water pollution problems everywhere: a destructive old habit of mixing drinking water with human waste (which we are, now sadly, all too used to)

• Today we have the means to go in a new direction, to stop destroying our drinking water AND the plant-nutrients in our manure, as well as protecting our environment AND make the visit to the toilet a more pleasurable on …

The ingenious alternative is:Enclosed Long Term Processing:

• Contains feces with its pathogens (and medical residues) for up to 40 years

• Yields plant nutrients as a clean, safe-to-use liquid fertilizer for agriculture

• Cuts 90% of the cost of waste handling: WASTE TRANSPORTATION

• Saves water used for flushing toilets• Prevents sewage from becoming pollution

What does it mean ?

• 1. For the user

• 2. For the up-keeper

• 3. For the architect

• 4. For the environment

• 5. For the greater picture

For the user, a toilet that is

• Odor-free and quiet

• Pleasing to the eye

• Comfortable to use

• Low maintenance

• Cost effective

Always odor-free

Always odor-free:• Before during and after

use• Constant air-flow down

the toilet ventilates the whole house and bathroom through the toilet

• Does not attract flies …

A silent fixture

• There is only a faint whisper of the fan

• Nothing to annoy you or wake you up at night if someone “goes”

Pleasing the eye --

• Pleasing design• Glossy white sanitary

outer surface• Scratch-resistant

acrylic coating• Easy to keep clean• Takes up little space• This is all users will see

Pleasing the eye -- inside

• Easy to keep clean

• On the inside, the optical illusion of … NOTHING

• Inside liner and tube are black -- so it blackens out anything that might be offensive to the eye.

Comfortable to use“Use and walk away”

• No flushing• No splashing :-)• Heated sit-ring

for cold nights• … and again

ALWAYS ODOR-FREE

Upkeep, service and maintenance

• CompostEra works for decades without the need to remove solids … very low maintenance.

• The liquid end-product is an odor and bacteria-free fertili-zer for use on-site or off-site

• The essential service consists of just cleaning the bathroom

For the architect

• The most reliable installa-tion is when the tank is under the bathroom floor …

• Simple and safe, no mechanical failures and the least service

• Excellent for remote locations where no grid electricity is available

For the architect

The treatment tank can also be inserted through the wall of a building and installed as a bench toilet

For the architect

� Or placing the treatment tank next to the outside wall of the house and open a bay in the wall of the bath-room. Can be done with a full floor or a bench toilet …

Bench toilet

Extended bay with floor

For the architect

� For use in a larger apartment building a Jets, on-demand vacuum system can be used.

For the architect

� For sports arenas, a Jets, on-demand vacuum system can bring the toilet waste to a central long-term composting reactor saving both water and eliminate pollution.

For the environment

This is where the Long-Term Processing excels above all others:

• There is no discharge so no pollution !• The process generates its own energy• It neither uses nor pollutes water• Pathogens and drug residues are contained and

isolated in the process for several decades• The liquid is the best safe fertilizer there is

containing both macro- and micro-nutrients

For the environment

• The liquid (from urine) undergoes a process called nitrification, generating nitrite and nitrate causing natural disinfection

• This takes place in the permanent filter-bed in the bottom of the tank

For the greater picture …

When we render human and animal waste safe to use as fertilizer, we also cut pollution in half since we don’t get run off from both chemical AND animal fertilizer !

For the greater picture …

• Animal fertilizer is the best fertilizer we can imagine, as it contains a full spectrum of macro- AND micro nutrients

• Chemical fertilizer only contains NPK (Nitrogen, Phosporous,Potasium) and will deplete soils of the crucial micro nutrients

For the greater picture…

• After repeated use of only chemical fertilizers, the micro-nutrients in the agricultural soils are depleted

• Then plants have less resistance to bugs and mold, requiring more pesticides …

For the greater picture …

• Chemical fertilizer makes crops LOOK big and colorful but it profoundly impacts nutrition, taste and smell.

• A typical supermarket tomato has no smell, no real flavor and no nutrition -- we can eat a basket full without feeling naturally satisfied

• An organic tomato has great scent, tastes good and after one or two we are naturally satisfied … “we feel full”

For the greater picture …

� So instead of poisoning our agricultural land with toxic sludge from sewage treatment plants (receiving everything that anyone wants to get rid of), it is high time to stop mixing drinking water and “wastes” and catch the plant nutrients before they are permanently destroyed by heavy metals, drug residues and persistent chemicals …

For the greater picture …• Enclosed Long-Term Com-

posting is our best bet to break a destructive cycle started by the effort to get the queens waste out of Windsor castle.

• Thomas Crapper designed the first successful flush toilet. It unfortunately set the norm for the whole world.

• Now we no longer need to use water to move toilet waste. We can safely and easily process it on site

Long-Term Composting

Let’s make this the technology of the future: Non-polluting, odor-free, silent, low energy consumption, and generating the best fertilizer there is for agriculture …

Public reaction to a new idea

The reception of new ideas that break with old habits, is said to go through 3 stages:

1. The new idea is met with ridicule

2. Then it meets with violent opposition

3. Finally, the people first opposing it will say

that they actually thought that way all along …
