Bismuth is a highly useful metal for engineers. And bismuth compounds abound in medicine. Yet high doses can dangerous. So we need a method to detect it in food, water and environment. Researchers from Coimbatore have now come up with one.

Mercury and Methylmercury: detect and discriminate

Mercury in the environment is dangerous to human health. Methyl mercury is even more so. Nilanjan Dey from BITS Pilani, Hyderabad has designed a cost effective and highly sensitive method to detect both.

Dealing with Dyes: Fungi to the rescue

Lakshmi Tiwari and Barkha Sharma from the G B Pant University of Agriculture and Technology, Pant Nagar have come up with a cute solution to water pollution by the dangerous dye, Congo red: agar plugs containing mycelia of the fungus, Penicillium crustosum.

Microplastics in Ballast Water: saving the seas

To stabilise ships in oceans, water is pumped in or out of the ballast depending on the other loads on the ship. If the water being pumped out is filtered ships can save the oceans from the emerging microplastic pollution, say Indian scientists.

Wastewater Reuse: Decentralising treatment plants

Centralised water treatment plants in urban areas have high cost of maintenance. Researchers from IIT Madras have now come up with a solution: an optimised network of grey water and wastewater treatment plants. A must read for municipal authorities.

Ethanol from Wheat Straw: Cheaper pretreatment

Researchers from IIT Madras have found a way to make the process of making ethanol from agro-waste cheaper. A move towards increasing farmers’ income, fulfilling fuel needs and reducing pollution from burning agricultural residues.

Heat loving Bacteria from the Himalayas: Breaking cellulose

Researchers from the CSIR-Institute of Himalayan Bioresource Technology have isolated a heat loving bacteria from the cold Pangi Valley of the Himalayas. The ability of the strain to break down cellulose very rapidly will find many industrial applications.

Hydrogen from Food Waste: Piloting the process

An estimated seven crore tonnes of food waste is thrown out by Indians every year, polluting the environment. Converting this waste into biohydrogen energy is an economic opportunity, say researchers from CSIR-IICT. Municipalities need to listen to this.
