Lab Grown Meat
- Cell-cultivated chicken, also known as lab-grown meat, has received approval from the U.S. government for production and sale by two California-based companies.
- This development is seen as a significant step in reducing carbon emissions associated with the global food industry.
- Cell-cultivated meat involves isolating cells that makeup chicken meat and providing them with the necessary resources to grow and multiply in a controlled environment.
- The process takes place in a bioreactor or cultivator. The cells are then processed with additives to enhance texture and appearance before being used in various recipes.
Importance
- Lab-grown meat is being developed to address concerns related to emissions, land use, animal welfare, food security, and customization.
- It has the potential to reduce greenhouse gas emissions and land use associated with traditional livestock farming.
- It offers customization options for healthier and more sustainable alternatives.
Lab Grown Diamonds
- India is a leading player in growing lab-grown diamonds, with exports reaching over $1.67 billion.
- Lab-grown diamonds offer a more affordable alternative to natural diamonds and are considered eco-friendly.
- They are around 20% cheaper than their naturally-formed equivalent
- India is the largest producer of lab-grown diamonds through CVD technology and contributes to nearly 25% of global LGD production through CVD technology.
- But overall, India accounts for 15% of the global production of LGD.
- World’s first ever Lab Grown Diamond was created at a General Electric Facility(USA) in 1954.
- Two processes are utilized for this :
- High Pressure High Temperature(HPHT)
- Chemical Vapour Deposition
- CVD technology offers consumers the purest type of diamond.
- LGDs produced through the HPHT method are grown through a different technique in China and do not have the same hardness as a mined diamond or a CVD-grown diamond and also contain metal impurities.
