At number 13 on IE's 22 best innovations of 2022, we look at the world’s first lab-grown wood.
Stop cutting trees! Will this slogan remain a slogan forever? We have been slaughtering trees as if they grow in a day and as if they are unlimited in number.of the total tree population on Earth, although it is common knowledge that uncontrolled deforestation is one of the main causes of frequent heat waves, droughts, and tsunamis.We still cut trees in large numbers on a daily basis for making products like paper, wax, medicines, rubber, and furniture.
So no deforestation and no wastage, like what happens in the case of traditional furniture. This was achieved by treating common zinnia cells first with a liquid medium and then with a gel solution. The latter comprised hormones and nutrients.By changing the concentration of these hormones, the researchers could control the stiffness, strength, density, and various other physical and mechanical properties of the lab-grown plant matter.
It is also the first-of-its-kind method that employs tissue engineering for producing plant matter in a lab. Until now, scientists have used this method for only animal cell culture. “Analogous concepts have not been translated to the plant culture space, particularly with respect to the production of materials. This work thus represents a first look at a cellular agriculture approach to plant material generation,” the researchersBeckwith and her team are now planning to 3D print timber in a lab from cells of trees like pine. Once this happens, deforestation would surely become a thing of the past.
