Startups Are Using Insect Larvae To Produce Protein-Rich Ingredients For Animals (nytimes.com) 57

An anonymous reader quotes a report from The New York Times: AgriProtein is among a small number of start-ups that are using insect larvae to produce protein-rich ingredients for animal feed. This nascent industry could help feed a growing human population in a way that's less damaging to the environment. Protix opened one of the world's largest insect farms in June in the Netherlands, while other producers, including Enviroflight, Ynsect and AgriProtein, are building large facilities to turn billions of insects into animal protein every month. Large farming companies like Cargill and Wilbur-Ellis are also investing in this sector. By breeding insects in vertical farms, these companies can produce large amounts of feed in less space than traditional farms, their proponents say. Proponents say this industry makes sense from a biological standpoint because insects are part of the natural diet of many animals, especially chicken and fish.

Despite the possibilities, the insect protein industry faces many challenges. Regulatory hurdles have hampered its growth in Europe and the United States, where black soldier fly products can be used to feed poultry and some fish species but not other animals, and there is no regulatory approval for the use of other insect species for this purpose. But companies are confident that regulators in the United States will lift those restrictions soon.
The report notes that black soldier fly larvae is favored by the "insect protein" industry because it "can become 200 times bigger after eating organic waste for 10 days."

      Indeed. Silkworm larva are quite tasty once you get used to them (better fried than boiled). Mealworms can be roasted, ground to a powder, and added to bread flour.

      People have also been using grubs as animal feed for thousands of years. I raise mealworms for my chickens. I also turn the compost every few days so they can chow down on the earthworms and maggots.

      • The excellent thing about mealworms is they're supposed to be able to feed on polystyrene. A vertical farm of these could solve a second problem as a useful recycler of waste that traditionally only goes to the landfill and is seen as a real problem.

          That would be an extremely inefficient way of breaking down polystyrene. The process requires feeding the mealworms a mix of bran and polystyrene which contains 5-10% polystyrene (by weight) and 90-95% bran.

          It would be far more efficient to process PS into synthetic diesel fuel, except that we are currently engaged in a global war on the most efficient ICE thermodynamic cycle in existence today, because we're stupid.

If nothing, they will be smaller engines that always run at their best efficiency and power batteries which in turn power the ship and larger, more powerful electrics to move the ship.

Diesel is efficient but the lean burn and high pressure tends to produce a lot more compounds that are difficult to deal with.

There are some people who say that we'll need to insect based protein in the future as meat production becomes limited in various ways, but there's long list of protein rich plant based meals I'd much sooner eat.

        Feeding insects to livestock is one thing, but as for me, if given the choice between a bowl of stir fried veges on a bed of mixed grains & legumes (which can very easily constitute a complete protein) or some s

            That is my main issue.. It's not the concept of eating insects... if you grind them into a meal I'm sure I wouldn't mind. But I already don't like seeing them much less touching and certainly not putting them in my mouth...

            Making a protein bread by mixing powdered insects with flour sounds like an idea :D.

      • I'm left wondering if this is such a concern why we keep incentivizing population growth in Africa and if we intend to continue to provide food for Africa, why these "eat maggots" "eat grubs" type solutions are targeted at western nations which as a percentage of the worlds population are rather negligible. I mean, looking to say 2060 which is around the timeframe these stories are concerned about, people of European decent are expected to only compose 10% of the worlds population...

        • Who's incentivizing population growth? It's probably that we're not doing enough to curb it.
          When people are poor, healthcare is bad and women don't work birth rates are high. When those places undergo economic development and a cultural shift where women working is the norm birthrates go way down. The only reason Africa's birth rate are so high is because they have yet mostly to undergo that process. Whether they'll get there before the Earth implodes due to human overpopulation is anyone's guess

      "Indigenous peoples" isn't a more woke way to say "savages", you know. Either way you're reducing them to their primitiveness.

    • Most cultures have some sort of Arthropods in their diet.
      Lobster, Crabs, even Grasshoppers are acceptable to western pallets.
      However most bugs in western cultures are associated with disease and decay. Which make us snub our noses at them as a good source.

      • Most of the association between insects and disease came from two insects in particular - flies and mosquitoes. The former because they hang around and consume things humans generally find disgusting (rotten food/corpses/etc, fecal material, stuff like that), and the latter because of fun things like West Nile and Malaria. And then of course we have insects like cockroaches, which happily compete with us for our own food, or wasps and fire ants, which inflict pain (and sometimes allergy reactions).

    • The difference between this and the debacles with the sheep carcass and mad cow is that you have species which naturally digest anything.You are not trying to feed them something which is utterly unnatural like feeding meat and bone (albeit processed) to a herbivore. A fly larva eats stuff which even pigs do not eat, it has evolved to digest it and defend itself against pathogens it may get from the feed (including eating its brethren).

    What does that mean for eating protein rich flies that have been feasting on organic shit for 2 weeks?

    • Nope. Major advantage of insect farming is quick turnover. Lifespans are short, so generations are short.

      That means the insects are born, grow up, give birth and die quickly. So harvesting must be done quickly - once a week at most. Most likely they would be killed and freeze dried or otherwise processed on site, every single day.

      As such, at any one time the number of insects held would be relatively small compared to the area they could escape to. The number of native insects would almost certainly

    The black soldier fly larvae have an additional trait that make them ideal for use in waste disposal systems.

    They can be self harvesting.

    They have an instinct to crawl away from their food sources when they prepare to pupate. Given an appropriately shaped container they will studiously crawl up a ramp and drop into a collection container. This allows continuous feeding and harvesting instead of the batch-type production common with worms and mealworms.
