      The final product is dried and harvested, with minimized water, land and energy use, Galy says.

      That’s why. Cotton is notoriously bad in all of those categories. To that I would add the most cotton grown commercially is paired with a lot of pesticides as well.

      • From an EU briefing on textiles and the environment:

        Cotton accounts for 24 % of global fibre production, according to Textile Exchange. It can be problematic because it can require huge quantities of land, water, fertilisers and pesticides and cannot easily be recycled into virgin fibre. However, the environmental impacts of organic cotton can be reduced drastically compared with conventional cotton, as it uses less water and pollutes less.

        The huge quantities of land required should absolutely not be underestimated as a climate problem. If we’re going to survive this we absolutely need to give land back to nature at a massive scale, and the easiest (humanely tolerable) way of achieving this is to produce the same goods at a much lesser surface area. Lab cotton could, hopefully, be efficiently grown in a high rise building with a minimal physical footprint.

        • Would be interesting to see how easily vacant office space can be converted to vertical farming, since developers seem insistent that it can’t be turned into residential space for various reasons. There’s rather a lot of it in the wake of work-from-home and the AI revolution.

        • Lab cotton could, hopefully, be efficiently grown

          While there are not many details this is hopefully a great step toward more efficient cotton production. There are a number of possible reductions from this method (hard to know without full details though), that being lower usage of land, water, pesticides, herbicides, and shipping.

          Longer term what I find exciting is the some of these lab grown systems may work well “closed loop” which mean they might work off planet at some capacity or another. That is a much longer term vision though and we have a long way to go before we master that aspect.

          • I guess for water getting a closed loop should be almost without challenge. I’m more interested in the potential of making life livable on earth though, at least in the short term. Still, the requirements are similar - lowered use of resources. :)

      • To make the Galy cotton, a team collects samples from a plant and harvests its cells. The cells are grown in bioreactor or fermentation vessels in a cell culture process similar to beer brewing. The final product is dried and harvested, with minimized water, land and energy use, Galy says.

        Maybe I just misread the sentence. But the full quote seems deliberately obtuse to me. They don’t explicitly say that they need less water than traditional farming.

      Cotton is one of the worst things to grow in 99% of the world yet we do it as a cash crop.

      In Australia cotton farmers are turning rivers dry, and if you know Australia we don’t have much water to begin with.

      In theory it could use far less land, water, fuel, and pesticides to achieve a similar output of a superior quality product, In theory. There’s a lot of labor resources and energy that goes into growing cotton. You could likely replace many hundreds of acres of cotton fields with a modest factory on 20 acres of land.

    • Cotton requires a lot of water and is considered a high risk crop with climate change. There are already failing crops, and cotton takes long enough to establish that it’s hard to adjust quickly. This is grown from cotton cells anywhere we can stand up a factory.
