Diet 2.0 – How Insects Help Make Your Food Waste Disappear

Roughly one third of all the food produced in the world for human consumption is wasted, according to the Food and Agriculture Organization. That is just not sustainable! Thankfully, insects are here to save our asses.

“Practically every substance of organic origin, including cellulose, is fed upon by one or more species of insects, so it is only a matter of time before successful recycling systems will be developed.” Gene R. DeFoliart, a professor at University of Wisconsin-Madison Department of Entomology (1)

Insects are biowaste conversion machines

Insect species such as the black soldier fly, the common housefly and the yellow mealworm are very efficient at bioconverting organic waste. These species could collectively convert 1.3 billion tonnes of biowaste per year (2). Other insect species, such as crickets, can also be fed organic side streams to help make insect farming more profitable (3).

Black soldier flies make protein from food-waste

This is not just all theory. Companies are already finding ways to utilize insects as waste management tools. For example a start-up Mad Agriculture feeds black soldier flies with food-waste from a local juicery to produce protein that serves as feed for farmed animals and fish, and is a viable candidate to replace soy.

"We can produce the equivalent to an acre of soybean protein in two weeks in this little tiny refinery (a room about the size of a shipping container) when it's fully cranking," says the founder, Phil Taylor. "Not requiring any fertilizer, no water, no arable land."

Crickets can be fed organic waste

Insects don’t have to be animal feed only. They can be a big part of human nutrition too. For example crickets that we use in our bars can be fed on organic waste like banana peels or rice bran. They make protein, essential vitamins, and minerals from plant matter that would normally be thrown away.

“The natural food of the cricket is not very well understood. We suspect they are omnivore insects, they eat several different food sources, mostly from decaying organic matter, vegetable organic matter, but they are also capable of eating animal food.” Juan Morales-Ramos, a research entomologist for USDA’s Agricultural Research Service

Skvelá chuť a výborná a hlavne zdravá alternatíva bežných ........ Nebudem ďalej prezrádzať čoho, nechajte sa prekvapiť!

Bigman powder!

This is the best protein powder on the market. I enjoy it after good and hard climbing session, and since i started using SENS' protein powder, i feel much than ever!

Fantastic bar!

The taste of the bar is so delicious. I enjoy it the most when i'm out climbing and so i can get that extra boost of energy.

Proteínové tyčinky

Proteínové tyčinky od SENS chutia jednoducho skvele! Pomer proteínu 20g na 60 gramovú tyčinku je výborný. O kvalite svedčia tiež poctivé, kvalitné suroviny priamo z farmy. Ak sa náhodou zaujímate o udržateľnosť, SENS je tá pravá voľba!

Výborný protein shake!

Proteín sa veľmi dobre rozpúšťa ako vo vode tak v mlieku (osobne preferujem kombináciu s vodou). Pre mňa ako človeka, ktorý sa snaží žiť ekologicky a využívať čo najviac eko produktov, je toto skvelá alternatíva k bežným proteínom. V porovnaní s ostatnými vysoko kvalitnými proteínmi je cena veľmi dobrá a spoločnosť sa ju snaží ešte znížiť. Za mňa TOP voľba! :)
