Water scarcity situation occurs when high rate of aggregate demand from all water-using sectors exceeds available supply, under the prevailing infrastructural conditions. From Cape Town to sub-Saharan Africa to Asia’s teeming megacities, there’s a global water crisis affecting millions of people. Water scarcity affects every continent and was listed in 2019 by the World Economic Forum as one of the…

PV module waste management – The next big challenge for the solar sector

Solar Photovoltaic (PV) technology has emerged as one of the most promising technologies for improving energy security and mitigating climate change. This market is growing rapidly world-over, and further exponential expansion is expected in the coming years. In addition to its positive impacts on energy security and climate change, PV technology is also among the most favoured renewable energy technologies, particularly when evaluated from a life-cycle viewpoint. In India as well, solar power capacity has grown from a mere 2,300 MW in 2013 to over 27,000 MW in 2018 at a CAGR of 64%, making India one of the top…

Can Plastic Roads be an Answer to the Global Plastic Waste Crisis?

Global Plastic Waste Crisis

One of the gravest environmental challenges facing mankind today is plastic pollution. According to conservative estimates by the United Nations, humans today produce more than 300 million tonnes of plastic waste every year and this figure is continuously on the rise. Even worrisome is the fact that only 9% of this waste gets recycled, 12% incinerated and the rest – more than 75% – gets dumped in landfills, water bodies and the natural environment worldwide. As a result, plastic waste has become a major environmental hazard polluting our cities, farmlands, rivers and even our oceans. Researchers estimate that at this…
