Zeri project: Monfort Boys' Town
ZERI have some great food security projects like this one: pigs, fish farming and polyculture veggies.
"The students at Montfort Boys' Town collect the sludge from the local brewery in Suva. This free input of barley mash becomes perfect substrate on which to grow mushrooms. This provides a local food source and more practical skills for the students.
"The students at Montfort Boys' Town collect the sludge from the local brewery in Suva. This free input of barley mash becomes perfect substrate on which to grow mushrooms. This provides a local food source and more practical skills for the students.
The substrate, mixed with rice straw or sawdust, is inoculated with fungus spores. As the mushrooms grow, they produce an enzyme that unlocks the protein in the grain, transforming it into nutritious animal feed. After the mushrooms have been harvested, the substrate is fed to pigs, eliminating the need to buy feed.
The waste from the pigs is collected and sent through a biodigester, a simple device that allows for treatment of solids and separation of gas. The methane gas from the biodigester is captured, bottled and used as an energy source for lighting and cooking.
The biodigester is the heart of the system, removing over 60% of the BOD (biological oxygen demand) and COD (chemical oxygen demand) of the waste within 3 to 6 days through anaerobic processes.
After the waste has gone through the biodigester, the remaining 40% of the BOD and COD is handled by using aerobic processes in shallow pools. The output of this process is algae, which becomes perfect feed for the adjacent fish ponds, accommodating a wide variety of fish.
The dykes surrounding the fish ponds are covered with a polyculture of various high-protein and fast-growing crops that require minimum attention. This biodiversity on the dykes also serves the crucial function of providing biological control of "pests," preventing the use of toxic chemicals.
Up to half of the surface of the pond is also being used to grow crops hydroponically, creating more local food, additional income and valuable experience for the students."

Not deliberately. Not sure mildew counts :) I tried to grow a box of mushrooms last winter but I my temperature control wasn't good enough, although I am not confident that the supplier gave me a decent starter block. Do you grow mushrooms?

Fourth of July on the Lake
This past weekend was the annual celebration at the lake house in Connecticut. It is amazing that the lake is still so clear and beautiful after all these years. The watershed association has done a wonderful job protecting these waters from the damaging effects of development.The wood grill was finally ready to cook on, so we didn't miss the propane tank fueled grill anymore. The food actually tasted fresher than in the past and was easy to keep fueled.Dad was very proud of the solar hybrid…See More
Stinging Nettle
In this blog post I will focus on a plant that is abundant in our nature, and which is immensely nutritious. It's of course the Stinging Nettle. Let's start with the chemical constituents of this plant:37 % Non-Nitrogen-Extracts19 - 29 % Ash9 - 21 % Fiber4 % Fat22 % ProteinOnce the leaves are drid, their protein content can reach an astounding 40 %, which is much higher than beef, which even under the best of circ**stances can never exceed 31 % protein. In addition the Stinging Nettle consists…See More
The meal
It is 7'oclock, I was late home from work due to an assignment that i wanted to get ahead on. By the time I get home I am feeling extremley tired and I cannot be bothered to make a proper meal. I walk to the fridge and open it to see what there is for me to eat. All of the out of date foodstuffs have been automaticaly thrown away by the fridge, they will be recycled tomorrow as animal feed or something. I see i have organic local eggs and some local cheese. Foods are vacc** sealded for easy…See More

Food was bought up xawayx at once. There were no more food supplies in any shops. The economy was all crushed down. All the…See More
public servants
The exchange works directly for state and public workers and servants. It gives them credit in exchange for the amount of public work they contribute to the community. The more constructive they are based off a base rate the more credit they recieve.
