Biofabrication Leather, Modern Meadow
(This is the type of Polynucleotides, comprising RNA and DNA)
Modern Meadow CEO and co-founder Andras Forgacs, they “biofabricates” its leather in labs and foundries made without animal hides. This new material, called Zoa, can even be made in a liquid leather form and is animal-free.
Present-day Meadow is a New Jersey-based trying to eliminate killing animals from the calfskin making process. Current Meadow has dispatched the world’s first bio calfskin brand — Zoa. With this bio manufactured bio fabricated leather, we can pour, shower paint, utilize 3D printing, make it thick, slender, and so forth, and do whatever other special treatments that you cannot do with traditional leather.
HOW IS IT MADE?
Zoa is produced using collagen developed from yeast in a lab. Collagen is a protein found in creature skin that gives flexibility and gracefulness and is vital to the attractive attributes of leather.
Biofabrication includes the plan of cells to create and assemble collagen and different proteins to yield leather that is “naturally indistinguishable” to traditional types.
Utilizing DNA-arrangement altering, common cells are changed into little production lines that produce collagen (primary protein structure in animals).
As they beat, the cells are quickly developed on a diet routine of nutrients until their collagen form a network structures.
The stringy sheet is then prepared into a “hide” that can be tanned and molded into different items.

The company didn’t show a sample that mimicked calf leather, which is the smooth, soft-yet-durable leather
- mimicking the type of animal hide they would like to reproduce, such as lamb hide versus cowhide.
- Plus this material can be grown to the size and shape needed, it is not limited by the size and shape of an animal, as with traditional leather.
- the desired aesthetics, dimensions and properties, it goes through a tanning and finishing process to finalize it into the leather.
- Marble swirl and a golfball-like stipple are not like any leather you’d find in nature.

Here is the process in pictorial form
- Take some skin sample from the animal
- Isolate and multiple cells are culture
- Deposit shell into sheets and induce collagen production
- Layer sheet together and leave to culture
- Fuse layers to form solid hide
- Tan hides into fewer chemicals and steps than required for conventional rawhide
- Finish, dye, & condition leather
- Fashion into finished products
