Two students from Indraprastha Vidyalaya in Mangaluru used Binbli juice to make eco-friendly rubber, and as a result bimbli sped the process of coagulating rubber latex by ten hours. While it usually takes formic acid close to 16 hours for the process, it took the fruit extract only six hours!
While a litre of formic acid costs up to Rs 325, the farmers spend another Rs 300 for para-nitrophenol (used to give the sheets colour). Naturally grown bimbli cuts down these costs completely while making the entire process of rubber sheet production eco-friendly. The same process that requires 100 ml of formic acid can be executed with merely 60 ml of non-toxic bimbli extract.
