The vermicomposting toilets are located just inland from the sea at Sombrio Beach on the southwest coast of Vancouver Island of Port Renfrew, British Columbia, Canada. The system has 2 pit toilets sitting over the outside chamber. There are 6 chambers, 3 for each of the 2 toilet buildings that sit atop of the constructed pit as shown in the photo. Once the first chamber is full, the toilet is slid over to the second chamber, and so on.

Essentially the wooden constructed area below the pit toilet building is lined with a fine mesh screen, so that urine can escape and insects together with the small animals can’t enter the system. All the human excrement deposits in this area and wood shavings are added periodically to the pile. Each chamber is approximately 12 square feet in size and with initial compost worms or red wigglers density of 4 handfuls or about 2 pounds of worms including bedding per chamber. When the area below the pit toilet is filled with excrement and shavings, the toilet is moved to the adjacent chamber.

As shown in the photo that along the wooden wall there are cross walls creating separate square chambers, each the size of the toilet building. Essentially there becomes the pile of excrement and wood shavings that has plenty of air flow. With the help of the compost worms and beneficial soil microbes, the pile is decomposed to a smaller pile of soil that can be excavated as humus from the chamber; so that the vermicomposting toilet building can eventually be moved back over it again for use.

The effectiveness of vermiculture and vermicomposting in human pathogen reduction for USEPA (United States Environmental Protection Agency) biosolids stabilization has been studied in Orange County, Orlando, Florida by Eastman et al (2001). A field experiment tested the feasibility of vermicomposting as a method for eliminating for four human pathogens indicator (fecal coliform, Salmonella spp., enteric viruses, and helminth ova) obtain USEPA Class A stabilization in domestic wastewater residuals (biosolids). It is an honor for me to be one of the co-authors of the article above.

The conclusion is that compost worms Eisenia fetida have a consumption rate of 1.5 times their biomass every 24 hours proportionally with the percentage of compost worm biomass to biosolids at a 1.7 ratio weekly. Additional biosolids should not be incorporated for a minimum 6 days to maximize pathogens reduction. Compost worms should not be harvested before this time.

Vermiculture – vermicomposting is safe for the environment, however due to compost worm population, sustainability and fluctuation, the stabilization time will need to be proportionally adjusted until a stabilization equilibrium is obtained and maintained as confirmed by sampling analysis.

According to the applied finding above, the baseline guide for quantity of compost worms and amount of biosolids to be stabilized and safe for the human can be described: Kilogram of biosolids divided by 7 = Biosolids per day divided by 1.5 (consumptive rate of compost worms) = Kilogram of earthworms required for stabilization.

There is no good or bad living creature in nature, all are the same and each has its own role in the natural environment. In a man-made environment living creatures are always sorted, beneficial creatures are cultivated or domesticated, while those which harm are eradicated. Domestication of plants and animals plays an important role in human history.

Domestication is totally different from natural selection. This artificial selection activity if not well controlled, will disrupt the natural balance (homeostasis) and slowly but surely turn out to be chaotic, or even fatal. The coronavirus pandemic this year is an example of the environment out of control by humans after the virus went beyond its carrying capacity in its natural host, presumably bats and then attacking humans.

Just remember that together with some scientists in North America once I conducted sanitation applied research in the early millennium regarding enteric (gastrointestinal tract) viruses along with other abdominal diseases namely fecal coliform bacteria, Salmonella spp. bacteria, and helminth ova (parasite of stomach worms). The four diseases are common in dirty areas and can naturally be controlled by earthworms.;jsessionid=8B25DCC845A1D907E7AD47D24AF1A405?doi=

In this research decomposer or saprovore, a detritus or dead particulate organic material-eating animal, the earthworm is symbiotic with beneficial soil microbes during the formation of soil, which can control the enteric virus naturally. Virus is a dead object containing debris in the genetic material of DNA or RNA, an infectious agent that can only breed in the body of living creatures ranging from bacteria to humans. Because it is not a living creature then viruses cannot be killed.

Amazingly the oldest animal in the earth that has nearly the same age during the cooling down of earth, an earthworm can control the population of the enteric virus by decomposing them.

One of the group of earthworms is the compost worm. This living creature is already on earth, evolved since millions of years ago. This compost worm produces antimicrobial which is called Fetidin to adapt in the “dirty” place that many living creatures cannot survive. Until now there has been no scientific report that earthworms become sick. They are disease resistant, they die by being killed, drought, or eaten by predators.

The cleansing or sterilization of COVID-19 outside the human body is one way that controlled distribution stops infecting and killing humans. Keep in mind this action also kills many other microbes that are beneficial for humans. This needs to be observed and anticipated, as well as how the food security and human immune system can be decreasing or less resistant to the disinfectant trials.

I was dreaming that the virus particularly coronavirus is like the virus in tulip flowers or tobacco plants, which can make the plant stronger and the color of the flower more vibrant. In fiction you may remember the young Batman received “power” after experiencing with a colony of bats in bad condition. Sure, someday the coronavirus can make us stronger (in immunity and economy) and reset our peace of mind to be more efficient in taking care of our community, environment, and living soil in the one and only world we have.

Over a year ago Bill Gates held up a beaker of human feces at the reinvented toilet expo in Beijing on November 6, 2018 to bring a message: unsanitary conditions are dangerous for our health as it was reported by Business Insider. From the outside, the toilet looks like any other pit latrine. The toilets involve no traditional flushing and aren’t hooked to a sewer system. Instead red wigglers or tiger worms or compost earthworms are introduced in a container below the toilet, and they feast on feces.

This idea is brilliant because clean water is getting to be too much a luxury to flush human feces in many countries. Giving the rest to the compost worms and the beneficial soil microbes to do their job as decomposers is a great innovation. The amazing creatures’ activity leaves behind a mix of water, carbon dioxide, and a small amount of worms’ poo or worm castings or vermicompost, Even it’s much less toxic and more nutrient-rich than ours.

Since 2015, a creative new type of toilet called the Tiger Worm has been introduced for testing in India. The Bill and Melinda Gates Foundation awarded $4.8 million in grant money to the London School of Hygiene and Tropical Medicine for research to improve the technology and USAID supported $170 thousand for initial testing in India, Myanmar, and Uganda. “We estimated that by 2030, the opportunity here is over $6 billion a year,” Gates said.

Most of us don’t really care about Bill Gates business for other reasons, but we like this idea. Now, after years of development and field testing around the world, the technology is finally reaching people who need it most.

The facts about worm toilets or vermicomposting toilets:
– Worm toilets require no traditional flushing and aren’t hooked up to a sewer system; instead, worms compost human waste.
– More than 4,000 such Tiger Worm Toilets have been installed to date across India, in homes of people who were previously defecating in the open area.
– The worm toilets smell a lot better than a pit latrine, and don’t breed mosquitoes and germs either.
– Here’s how a $350 prototype toilet powered by worms could change the world and saves lives.
– The worms and soil microbes produce a water, carbon dioxide, and worms’ poo or worm castings, that’s much less toxic and more nutrient-rich than ours for the fertility of this planet.

Vermicomposting toilet is safe for the environment, however due to compost worm population, sustainability and fluctuation, the stabilization time will need to be proportionally adjusted until a stabilization equilibrium is obtained and maintained as confirmed by sampling analysis.

Oxford Committee for Famine Relief (Oxfam) and International Institute for Hydraulic and Environmental Engineering (IHE) Delft have been developing the Tiger Worm Toilet in Rakhine State, Myanmar since last year. This type of toilet operates at a communal level to serve up to 20 people in refugee camps. One of the biggest challenges in refugee camps is sanitation and the management of human feces. The compost worms convert the human waste into a dry and easier to handle dry worm castings or vermicompost. The photo is courtesy of IHE Delft, The Netherlands.

Nomadic vermiculture – vermicomposting is organic waste management in situ (on-site), mostly outdoor or in the greenhouse using the compost worms or red wigglers. Compost worm is epigeic or surface-litter dwelling earthworm that can help to process the organic waste from the plantation (fruits, leaves, succulent stems, and processing wastes), farm (manure, bedding), and food waste from the village nearby become high quality worm castings or vermicomposts to create the living soil.

The process of vermiculture – vermicomposting is in the trench or garden bed nearby the plant canopy. The worm castings produced during the vermicomposting will not be harvested but will be used directly by plants, so it will save the energy and time for the worm castings application. The excessive compost worm population will be harvested and transferred to the next new trench around the plantation with different mature trees.

Unlike nomadic vermiculture- vermicomposting in the trench or garden bed, worm tower is a permaculture (permanent agriculture) innovation designed to allow compost worms or red wigglers to compost food waste, garden waste, farm waste etc. in a closed container with holes at surrounding. This allows worms to come, stay, and go as they wish in the garden. The basic idea is that the compost worms will be safe, not eaten by the predators (e.g. birds, rats, raccoons etc.). They will do their job to decompose the food waste become worm castings or vermicompost for plants, and the container with holes will aerate the soil; so that it has a healthy and less foul smell soil.

Although the red wigglers are not real deep burrower earthworms, they can thrive in the environment with rich in organic matters inside the worm tower. Moreover, worm tower can create a better soil environment and invite the native earthworms (anecic or deep-burrowing earthworms and endogeic or upper-soil earthworms) that can be used as a bioindicator of the healthy and productive living soil toward the natural way of farming.

The concern with the size of the worm tower, it should not be too small at least in 1 foot diameter and 2 feet depth so it will not lack the surface area as the red wigglers like most to thrive. The density of the red wigglers at least 2 handfuls or about a pound of worms including original bedding from the vermiculture activity. This bedding is important because it contains beneficial soil microbes that will act as a probiotic starter for the worms.

Moreover, the bedding is creating a suitable environment for the worms to thrive through their cocoons (compound eggs) production. Enough organic waste in the worm tower will warm-up the temperature during the harsh winter and cool-down the temperature during the hot summer. And pouring rain will not disturb the worms inside as there are enough holes around the worm tower and the water content of the earthworm is over 90%. The soggy waste will be okay for them, as far as in aerobic condition and the water can escape well through the soil. Watering may needed during the dry summer.

Composting has a long history since Marcus Porcius Cato mentioned it in his manual on running farm “De Agri Cultura” (On Agriculture) in the early Roman Empire in 160 BC. Traditionally people at that time piled organic materials until the next planting season. The term and concept of organic farming originally was introduced in 1920s by Sir Albert Howard in the United Kingdom based on his work with organic gardening at Indore, India. Basically, he was promoting the concept of management of a farm as a living unit or whole system. Before the development of synthesized fertilizers and pesticides, practices of crop rotation and fertilization with animal manures and legumes were the options available to most farmers to maintain crop productivity.

Indore ninety-day process of composting was found by Sir Albert Howard. He offered genuine help to his neighbors by demonstrating composting methods they could easily afford and use through layer by layer carbonaceous and nitrogenous materials with regularly turning to keep thermophile microorganisms thriving. What was truly revolutionary was Sir Howard’s finding the amount of nitrate nitrogen in the finished compost was higher than the total amount of nitrogen contained the materials that formed the heap. Composting in North America was developed by Jerome Rodale and his friends at the Rodale Organic Gardening Experimental Farm in 1940s.

For the beginning composting lovers, Cornell composting is the most comprehensive and simple guide for doing basic and up to date composting around the globe. Start from the science and engineering of composting (casual composters, background information, getting the right mix, composting experiments, compost engineering fundamentals), composting in schools (teacher’s page, compost quiz, composting indoors and outdoors, weird and unusual composting, frequently asked questions, glossary), and hundreds composting fact sheets. Their mission is: “Everything you ever wanted to know about composting, but were afraid to ask? Not quite, but we do hope we’ve assembled some useful information.”

The progress of composting around the globe is amazing but still cannot process all organic waste produced by human activities. The Cornell’s Composting can be used as a model of the large-scale composting. Each year Cornell University at Ithaca through the Farm Services composts about 4000 tons of organic waste annually into a quality compost originally from: 2700 tons of animal bedding and manure from research and teaching facilities. 300 tons of plants debris from campus greenhouses, orchards, and farms. 850 tons of food scraps and other organic waste from their All You Care to Eat dining rooms and their retail dining eateries. The rest is from other waste streams, such as building-specific compost collection programs and special events.

It was reported by Schwarz and Bonhotal (2018), in 2013 Cornell University Farm Services diverted about 6714 tons of organic waste to the compost facility. It was calculated the Cornell’s compost facility emitted 104.6 metric tons carbon equivalent (MTCE) and saved 201.4 MTCE through compost use for a total carbon footprint saving of 96.7 MTCE per year (carbon negative). This equates to 0.0154 MTCE per ton feedstock emitted 0.03 MCTE saved through compost use for a total carbon footprint saving of 0.0146 MTCE per ton fresh organic waste. These values are specific to this facility, but the calculations can be used by other compost facilities to calculate the carbon footprint of composting.

It’s a great pleasure to visit the compost facility of the Cornell University in Ithaca, New York this Winter and they always keep a warm welcome. The main goals of the visit is to do networking and forecasting that at least 10% of the compost facility and capacity should try to use vermiculture – vermicomposting to speed up the process and increase the quality of the finished product vermicompost or worm castings, also to produce protein from the worms biomass.

The photo above was taken at the compost facility nearby the Cornell University campus in Ithaca, New York last December 2019. Nothing to lose, composting – vermicomposting cooling the earth and warming the universe.

Amicus humani generis, friend of the human race. Photo by the author. Permission is needed for the publication.

There is a misunderstanding about earthworm in the old scriptures. Many people believe worms as an expression of lust, covetousness, greed, selfishness, destruction, putrefaction, weakness, and humiliation. Most of them referred to the larva of beetles (grubs) or larva of moths (caterpillars) as pests and larva of flies (maggots) which eat directly the fresh flesh. Everything is considered disgusting because it is related to death.

In fact, all earthworms are saprovores or decomposers and they love dirt! The nutrition they eat comes from things in soil and compost, such as decaying roots, leaves and other organic wastes. In symbiotic mutualism or friendly relationship way, they eat living microorganisms such as protozoans, bacteria, and fungi in soil to be able the beneficial soil microorganisms to thrive and the plants to grow better with the additional humus layer produced by earthworms.

In the book: Opening the Door of Your Heart: And Other Buddhist Tales of Happiness (2005), Ajahn Brahm mentioned that worms are in a dirty, low-level place so they need to be saved. On the other hand, saving the worms can be considered waste time and full of risk because they think worms can bring contamination and they are dirty. Actually, salvation that is forced often shows arbitrariness and useless. Especially if the worms are happy in their habitat. Salvation is full of mystery and can be fierce.

One fictional story about earthworm started from here. There are two monks who have lived together in a monastery for years; they are good friends. Then they are getting older and died almost at the same time. One of them is reborn in the heavenly realm, the other one is reborn as a worm in a pile of dung.

The monk in heaven who is very happy and enjoying all the pleasures of heaven begins to think of his friend. “I want to know where my old friend is.” He observes all the heavenly realms and does not find any trace of his friend. Then he observes the human realm, but he does not find any trace of his friend there either. So, he looks in the animal kingdom and then lowest-level creatures on the ground.

Finally, he finds his fellow monk while in the world, reborn as a worm in a pile of dung … Wow! He thinks: “I can help my friend, sure, I will go there to that pile and bring him to the heavenly realm so that he can also enjoy the heavenly pleasures and happiness of living in this beautiful realm.”

Then he goes to the pile of poop and calls his fellow. And the little worm stretches and says, “Who are you?”. “I am your friend.” But the worm says, “Go away, you are lost!” “I am your old friend, I live in the heavenly world”, and he describes the beautiful heavenly world to him. The worm says, “No thanks, I’m quite happy here in my pile of poop. Please just go.”

Then because of the influence of the heavenly mind, the ex-monk thinks: “Well, I’ll just grab him and take him to heaven, so he can immediately see by himself.” So, he grabs the worm and begins to pull it towards him; and the harder he pulls, the harder the worm sticks to the pile of excrement.

One hundred eight times the deva (in Zoroastrianism deva means evil) tries to lead the “poor worm” out from his miserable dung pile, but the worm is so attached to his lovely pile of dung that he always wriggles back! Eventually, the deva has to go back up to heaven and leaves the “foolish worm” to his lovely pile of dung as infinite and renewable resource.

Worms are a metaphor of guilt. The guilt that departed souls experience when they leave this world. The worms indicate the pain that the deaths go through, leading to suffering after death. Moreover, historical religious events have been told in the Abrahamic (descendants of Abraham) religions using worms as the main cause behind them.

In the real world, earthworms are friends of the human race, amicus humani generis that most people, farmers, breeders, and scientists understand and have proven their role in soil fertility, as a bioindicator of soil productivity, and in resource waste management including protein production. Once it was reported by the National Geographic magazine that earthworms are the most influential species of all evolution on earth. They may save us, and save this planet through the healthy soil.

It was a great pleasure to share this idea with the staff from the Cornell Lab of Ornithology and Compost Facility, and the director of Cornell Waste Management Institute at the Cornell University, Ithaca NY last month. Also for the tour to see all possibilities to exchange the experience,

My first visit at the large compost facility abroad was at the waste management company at VAM (Vuil Avfoer Maatchappij) in the Netherlands in Summer at the end of the last millennium. I was impressed with the waste transportation by train operated by the company from the towns directly to the facility, control system for monitoring the processes of composting, and thousands seagull birds at the compost facility. Seagulls can be used as a bioindicator during the early stage of the decay of the organic material can still be used as food to create the energy for them before doing a long migration facing the Winter. As far as the composting facility is not nearby the airport, the high density of the bird traffic may not disturb the human air traffic.

One of the largest birds of prey in North America is the bald eagle. It is very beautiful with the plumage of an adult with dark brown, white head and tail, and bright yellow beak and claws. Most of the bird watchers will enjoy much to watch the bald eagle, unfortunately in nature they always fly high and stay at the highest tree. It was found that the bald eagles stay nearby the compost facility during the winter and become tame. They enjoy the warm climate and abundance food at the compost facility. It was reported recently by CBC (Canadian Broadcasting Corporation), during the Winter almost 800 bald eagles were counted on a single day at the composting facility in Delta, British Columbia. They keep warming and feasting on organic scraps and seagulls instead of salmon.

The most amazing story is about the bird that make a compost pile. In Australia, there is a bird called the brush-turkey (Alectura lathami) that builds large nests made of leaves, other composting material, and dirt. They build compost pile to incubate their eggs so that they will not have to sit on them. The heat produced by the microbial decay maintains the eggs at about 33 – 35°C or about 15°C warmer than the ambient air temperature. Because each nest generates more than 20 times the heat production of a resting adult brush-turkey, many more eggs can be incubated this way than if they relied on warmth from the parent birds. Male brush-turkey builds the compost pile on shady areas beneath trees (about 80% shade) to attract the female to lay eggs that can be up to 24 eggs per mating season.

Each nest can be 1 to 1.5 meters high and up to 4 across meters. The largest brush-turkey’s nests were on Kangaroo Island in South Australia, where the average mound measures about 12.7 cubic meters and weighs about 6,800 kg. Scientists have constructed a computer model using data on mound size, ambient temperature, and the nest’s rate of heat production, water content, dry density, and thermal conductivity. The model predicts that as little as 1 cm of litter added to the mound will raise the core temperature about 1.5°C. Experiments indicate that the composting nests require (1) a critical mass of fresh litter (about 3,000 kg), (2) sufficient water content (more than 0.2 ml/g dry material), and (3) occasional mixing of the litter. This bird is clever by instinct and doing.

Nature gives a chance and everything. The Australian brush-turkey checks the temperature by sticking its beak into the compost pile. The temperature of the pile is regulated by adding or removing material to maintain the temperature in optimum. Like in some reptiles, incubation temperature will affect the sex ratio of chicks. It was reported that the sex ratio in brush turkeys is equal at the incubation temperature of 34°C, but results in more males when cooler and more females when warmer. Whether the parents use this phenomenon to manipulate the sex of their offspring by selecting the nesting site accordingly is still unclear.

The photo is courtesy of Esther Beaton, Australian Geographic. A pair of brush-turkey female (left) and male (right) on the compost pile.

It seems that we can use the warm climate and leftover resource specially during the Winter time to create the rest energy at the compost facility for other purposes. It is not only for the organic waste management and producing the compost, but also for producing beneficial soil microbes and protein such as single cell protein, bird protein, and worm protein in the near future.

Forgetting is a natural process, it is impossible to be resisted if it’s time to forget. Forgetting once is human as long as you don’t forget too often. The worst is three types of forgetting: First, if we pretend to forget. Second, it’s hard to forget something that is less pleasing to us. And third is forgeting everything due to neurocognitive or degeneration disorder such as Alzheimer disease, which causes dementia syndrome in more than 60 – 80% of the elderly.

One of the traditional medicines or supplements to fight forgetfulness is Ginkgo biloba. There are two different approaches of using Ginkgoes in Eastern and Western medical literature. The medicinal uses Ginkgo extracts mainly using the seeds in the East, and mainly the leaves in the West. It is well known that these herbs can be used to restore a better memory. Although it has not been clinically proven yet, many people try the Ginkgo extracts, and there are those that are suitable to get the benefits.

Ginkgo biloba is good for two choices of fighting forgetfulness. It seems that the Ginkgo extract is a kind of placebo, a kind of treatment just for pleasure that is more psychologically useful (mental suggestion) than physiologically (bodily functions). The plant tree has existed since two hundred million years ago since the Permian geological period, at the same age with dinosaurs. The remaining plants are more than two thousand years old and are often called living plant fossils because of the disease resistance and long life. Taking Ginkgo biloba extract is more to appreciate this plant, to thin the blood, and if it is suitable it will not cause allergy like itching. Who knows that it will be useful for some of the believers in alternative medicine?

What is very difficult to forget is the smell of female plant flowers (ovules) which fall out of a very smelly, smell like vomit. Male plant flowers (cones) smell neutral and need for pollination. Ginkgo seeds taste good when boiled. If the raw is not processed the seeds are very poisonous because they contain neurotoxins. They look a bit like a pistachio. There are records of the seeds eaten by dogs, badgers, squirrels and others, and they do not feel good afterward, so they vomit. This must be part of a dispersal system of the Ginkgo seeds. Recently there are more likely some mammals died because eat too much the Ginkgo seeds. There is a hypothesis that the Ginkgo seeds smell would have attracted dinosaurs to eat it because it is nutritious like meat.

Every time I was under Ginkgo tree, whether male or female, young or old, I always remember that Ginkgo tree has been passing the long natural selection exposed by the natural harsh weather during the earlier development of earth since many generations and they can survive well until now. Learning from the resilience of Ginkgo biloba, hope that we can pass the climate change, to be strong like a Ginkgo tree with disease and pollution resistances, high adaptation, and long life.

As we are approaching the end of this year, we must not forget that the climate change is getting worse for the sustainability of the young generation. The climate change can affect on earth’s geophysical (e.g. global warming, swift of the magnetic field, extreme or unpredictable weather, earthquakes, etc.), geochemistry (e.g. ozone depletion, drinking water depletion, increasing environmental hazard, etc.), biological (e.g. loss of biodiversity, global spread of infectious diseases, migration, foods shortage, decreasing soil fertility, etc.), ecological system (e.g. floods, drought, forest fires, crops and farms availability, change in land-use, etc.), and disruption of the polar vortex at the earth’s atmosphere that cause cold-snap, tropical cyclone, any kind of storms but not the Winter storm.

Sure, that the Ginkgo tress passed the survival of the fittest against climate change in the past and will survive in the future, but human may suffer seriously if we do not take any action seriously.
