Urea: Make or Buy
The policymakers are pondering over a question whether it is worth “making” urea at $ 400 per tonne or more when you can import (“buy”) at under $300?. Other sections advocate for achieving self-sufficiency in this critical nitrogenous fertilizer. Why India must augment the capacity of local production? The domestic production cost also involves customs ..

Tezpur University‘s researchers develops a low-cost filter to remove arsenic from water
Researchers at Assam’s Tezpur University have developed a simple and cost-effective filtration system – Arsiron Nilogon – that may help reduce the health burden caused by arsenic and iron contaminated groundwater. The system filters out 99.9% of the arsenic contamination from the groundwater to make it suitable for drinking. The chemicals used in the filtration ..
