Bisket Labs Develops Sustainable PCB Substrates from Farm Waste
Bisket Labs is a company that makes the base part of electronic circuit boards, called substrates, from farm waste instead of the usual materials made from oil.
This is good for the environment because it uses less oil and reduces farm waste.
The company started by making a sticky liquid from farm waste and then turned it into a hard material.
They tested it for many uses and found that making circuit boards was the best idea.
The new material works like the old one but is made from things like rice straw and sugarcane waste.
It can be composted in about eight months.
The company is working with local factories to make sure the new material works well in real production.
They are starting with simpler electronics like LED lights and home appliances.
The founders believe this can help countries make their own electronic parts without relying on imports, which is good for both the environment and the economy.
Bisket Labs is developing a PCB substrate made from agricultural waste to replace traditional FR-4 substrates.
The material is 80% bio-based by volume and can compost in soil in about eight months.
The company is working with local PCB manufacturers to test and refine the material for commercial production.
Current applications include single-layer PCBs used in LED lighting, home appliances, industrial controls, and power supplies.
The technology aims to reduce agricultural waste, decrease dependence on fossil-derived materials, and build more resilient domestic electronics supply chains.
