Marlow Foods in Stokesley, UK, which produces the plant-based brands Quorn and Cauldron, reported a 4.8% drop in revenues in 2021. Other companies also seem to be experiencing a slowing of sales. Gut feeling: building a picture of Latin American microbiomes But after the initial excitement, sales slowed, and they have remained about the same since 2020.

When meat-substitute company Beyond Meat in El Segundo, California, went public on the stock market in 2019, its share price rose by 163%. Meanwhile, sales of plant-based alternatives to meat that are designed to reduce the demand for cattle farming - an industry responsible for 65% of all livestock emissions - seem to be stalling. And the global market of the vertical-farming industry is expected to grow from US$3.7 billion in 2021 to $10.5 billion in 2026. Several start-ups (including Infarm in Berlin and Aerofarms in Newark, New Jersey) use the system to produce vegetables such as lettuce for human consumption. The use of vertical farming has grown rapidly over the past few years, spurred on, in part, by advances in LED lighting, the cost of which fell by 94% between 20. This is given to fish, pigs and poultry, taking the pressure off conventional agricultural land use.Ĭattle farming is a target for emissions-reductions measures. However, because mealworm burgers are, at the moment, unlikely to sell out in your local supermarket, Ÿnsect grows insects for animal feed. With the global population expected to reach almost 10 billion by 2050, United Nations forecasters have warned that food production will also need to increase by as much as 70%. “Insect protein is one very realistic and obvious solution to mitigating some of those challenges,” he says. So why farm insects at all? “The world is facing a huge food sustainability crisis,” explains Hubert, an environmental engineer. And some researchers have concerns about the effects on the environment, ranging from whether escaped insects might disrupt local ecosystems to the impact of insect ‘factories’. But various attempts by companies to market insects as a mainstream food source in Europe and North America have fallen flat and largely been dismissed as a fad. To produce the same amount of protein, for example, crickets require around six times less feed than do cattle, four times less than sheep, and half that of pigs and chickens 2. Insects also have a high food-conversion ratio when compared with livestock.

A direct nutritional comparison shows that edible insect species have greater protein potential than do conventional meat products - 100 grams of mealworm larvae produces 25 g of protein, whereas 100 g of beef contains 20 g of protein 1. Insects have come under the spotlight over the past few years, as scientists seek alternative sources of protein to feed the rapidly expanding global population. Will cell-based meat ever be a dinner staple? The beetles are raised in this way from larvae to adult, at which point they meet a quick death in steam before being harvested into oil, protein and fertilizer. Nutrition, growth and moisture levels are all recorded for analysis, and human visitors are allowed to inspect the trays only from a distance - to prevent contamination of this prized ecosystem. Each of their stacked plastic trays is kept at an optimal 60% humidity and a balmy 25–27 ☌. The company’s chief executive and co-founder, Antoine Hubert, says that the beetles have a good life, as far as being an insect goes. At 17 metres high, this is the world’s largest vertical insect farm - home to at least 3 trillion mealworm beetles ( Tenebrio molitor). With it comes the realization that this is not a typical factory.
