Crop Waste like rice husks, sugarcane bagasse, and fruit peels are being transformed into biodegradable plastics (bioplastics) by using their cellulose and starch content, offering sustainable alternatives for packaging and other products, with processes involving grinding, binding, and sometimes microbial fermentation to create materials that break down naturally, reducing plastic pollution and utilizing agricultural byproducts.

Crop Waste like rice husks, sugarcane bagasse, and fruit peels are being transformed into biodegradable plastics (bioplastics) by using their cellulose and starch content, offering sustainable alternatives for packaging and other products, with processes involving grinding, binding, and sometimes microbial fermentation to create materials that break down naturally, reducing plastic pollution and utilizing agricultural byproducts. 
How it works
Sourcing raw material:-
 Agricultural waste rich in cellulose and starch, such as corn, potatoes, banana peels, rice straw, and sugarcane bagasse, is collected.
Processing: -
The waste is cleaned, dried, and ground into fine powders or dust.
Extraction/Fermentation:
Cellulose-based: -
Cellulose is extracted and converted into cellulose acetate.
Starch-based: -
Starch is fermented into sugars, then into lactic acid, which is polymerized into Polylactic Acid (PLA).
Microbial: -
Some processes use bacteria to produce PHA (polyhydroxyalkanoate) from organic matter.
Blending & Forming: -
These biopolymers are blended with natural binders and molded or extruded into various forms like plates, cups, films, or insulation.
Biodegradation: -
The resulting bioplastics can decompose in soil or water, breaking down into natural elements, unlike conventional plastics. 
Examples and applications
Rice Husk Plates:-
 Strong, water-resistant plates that decompose in 90 days.
AgroRenew: -
Turns melon and pumpkin waste into bioplastics.
IIT Madras: -
Uses mycelium grown on agricultural waste for packaging.
German Researchers (EcoPBS):- Developing polybutylene succinate (PBS) from crop waste for medical, auto, and packaging uses, resembling traditional plastics in strength. 
Benefits
Reduces plastic pollution: -
Offers an alternative to petroleum-based plastics.
Manages agricultural waste: -
Turns unwanted byproducts into valuable resources.
Lower carbon footprint: ,-
Significantly smaller carbon footprint than traditional plastics. .

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:-  ...

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...

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.
