Recent chemical breakthroughs convert plastic waste into fuel without the need for expensive, energy-intensive sorting. Advanced methods use specialized catalysts—such as cobalt-nickel or aluminum molten salts—to break down long hydrocarbon chains in plastics like polyethylene and PVC, converting them into aviation fuel or gasoline-like hydrocarbons.

Recent chemical breakthroughs convert plastic waste into fuel without the need for expensive, energy-intensive sorting. Advanced methods use specialized catalysts—such as cobalt-nickel or aluminum molten salts—to break down long hydrocarbon chains in plastics like polyethylene and PVC, converting them into aviation fuel or gasoline-like hydrocarbons. 
The main chemical approaches transforming plastic into fuel include:
Alkaline Thermal Treatment (ATT):- This method mixes plastic with sodium hydroxide to chemically "cut" the polymer chains at a molecular level, producing high-purity hydrogen gas for clean energy. 
Catalytic Hydrogenolysis: -
Used by researchers in China, this two-stage tandem reactor system uses custom catalysts (such as ruthenium on cobalt-aluminum oxide) to cleave internal carbon bonds, converting 80% of waste polyolefins into aviation-grade C₈ - C₁₆ hydrocarbons. 
Molten Salt Catalysis: -
Developed at the US Department of Energy's Oak Ridge National Laboratory, this method uses cheap aluminum salts to convert stubborn polyethylene waste into gasoline and diesel-like fuels without needing external hydrogen.
These methods bypass the traditional, highly polluting processes of melting or incineration by selectively separating carbon bonds, paving the way for scalable, sustainable chemical recycling.

State-wise carbon emissions in India show a concentration in western and southern states, with byd as major emitters, particularly from the manufacturing and energy sectors. The highest total CO2 emissions have been linked to states like Maharashtra, Andhra Pradesh, Uttar Pradesh, Gujarat, Tamil Nadu, and West Bengal, though the specific ranking can vary depending on the data year and the specific pollutants included.

Hydrogen at home — It's the end of solar and wind power

  Hydrogen at home — It's the end of solar and wind power         Statement "1000 pounds" per day of hydrogen at home — It's the end of solar and wind power in the world" is not accurate.     While hydrogen can be produced from renewable energy sources like solar and wind power, it's not a replacement for those sources themselves. Hydrogen production via electrolysis, using renewable electricity, is a promising avenue for decarbonization, but it doesn't negate the need for solar and wind power as direct energy sources.  Cause behind its is as under. Hydrogen as an Energy Carrier:-     Hydrogen is an energy carrier, meaning it stores energy produced elsewhere (like from solar or wind) and can be used to power fuel cells or for other applications.  Electrolysis:-     A key method of producing "green" hydrogen involves using electricity from renewable sources (like solar and wind) to split water into hydrogen and oxygen throu...

Solar Generation in Night hrs

How to get get Solar generations in Night        While standard solar panels cannot generate electricity at night,     New technologies are being developed to address this limitation.      These advancements focus on harnessing the earth's heat or using infrared radiation emitted by the Earth to generate power, potentially creating 24-hour renewable energy sources.  Key Concepts and Technologies :- 1) Anti-Solar Panels (Thermo-radiative Cells):- How they work:-    These panels, also known as thermoradiative cells, work in reverse of traditional solar panels. Instead of absorbing sunlight, they emit infrared radiation into space, which is then converted into electricity.    Nighttime energy:-     They can generate electricity from the difference in temperature between the panel and the surrounding environment, essentially converting the heat escaping into space back into usable power.  Potential:-  ...
