Bio-derived Foam

Researchers at the Indian Institute of Science (IISc) in Bengaluru have developed an innovative, eco-friendly bio-derived foam recently.

  • It is a bio-derived foam that offers a sustainable alternative to plastic materials used in traditional Fast-Moving Consumer Goods (FMCG) packaging.
  • The foam is made from bio-based epoxy resins, made from non-edible oils approved by the US Food and Drug Administration (FDA) and hardeners derived from tea leaves.
  • It is an alternative to conventional expanded polystyrene (EPS) and polyurethane (PU) foams.
  • It disintegrates in landfills without contaminating groundwater, offering a sustainable alternative to traditional plastic foams.
  • These bio-foams can disintegrate within 3 hours when exposed to eco-friendly solvents at 80°C.
  • The foams contain chemical bonds that can be broken and reformed in response to external stimuli.
  • This allows the material to be mechanically reprocessed or dissolved in eco-friendly solvents within hours.
  • It is sustainable packaging solutions, offering industries an environmentally responsible.

Each year, around 2.3 million tonnes of plastic foam are produced worldwide, but less than 1% of it is recycled.

  • Significance - Researchers said the production of 10,000 traditional plastic foam cups results in approximately 308 kg of greenhouse gas emissions.
  • The Indian foam market, valued at USD 7.9 billion in 2023, is expected to grow to USD 11.1 billion by 2032, with a compound annual growth rate (CAGR) of 3.85%.

International Chess Federation (FIDE)

An Indian prodigy, Anish Sarkar, has become the world’s youngest chess player to be ranked by the International Chess Federation all at the age of three.

  • The International Chess Federation (FIDE) is the governing body for international chess competitions and the organization that connects national chess federations.
  • FIDE regulates all international chess competitions and is responsible for organizing chess and its championships at the global and continental levels.
  • Founded in - Paris, France on July 20, 1924.
  • Its original name in French is Fédération Internationale des Échecs, which is where the acronym FIDE comes from.
  • Headquarters - Lausanne.
  • Motto - FIDE's motto is Gens una sumus, which is Latin for "We are one Family".
  • Member federations - 201 member federations.
  • The International Olympic Committee (IOC) recognized FIDE as a Global Sporting Organization in 1999.
  • FIDE also keeps records of players' ratings.

FIDE Rating system

  • According to the FIDE Qualification Commission, players get official ratings by participating in FIDE-rated tournaments.
  • The FIDE Rating system is a numerical system in which fractional scores are converted to rating differences and vice versa.
  • Its function is to produce measurement information of the best statistical quality.
  • Eligibility - To become a FIDE-recognized tournament, certain regulations on time limits for a game, a minimum rating for players and other criteria must be met.
  • Also, to be included in the rating list, a player must be registered through a national chess federation which is a member of FIDE, unless otherwise approved by FIDE Council.
  • The federation must not be temporarily or permanently excluded from membership at the time.
  • Types of rating - Standard, Rapid and Blitz, which reflect different game lengths.
  • In order to get a Standard rating, you will need to play at least 5 games against players who are already rated, and score at least ½ point (a draw) in those games.
  • Currently, FIDE awards chess’s highest honor to a player who is able to achieve a FIDE Classical or Standard rating of 2,500, plus 3 Grandmaster norms.
  • These norms are defined by a set of complex and rigorous rules regarding tournaments, games, and players, set out in the FIDE Title Regulations.

Microplastics

Recently, the researchers founded that microplastics could be affecting weather and climate by producing clouds.

  • Microplastics - They are fragments of any type of plastic less than 5 mm (0.20 in) in length.
  • They can originate from larger plastic waste as it breaks down, Resin pellets, Microbeads, Tires, Synthetic clothing.
  • The problem with microplastics is that like plastic items of any size they do not readily break down into harmless molecules.
  • On beaches, microplastics are visible as tiny multicolored plastic bits in sand.
  • In the oceans, microplastic pollution is often consumed by marine animals.
  • Types of Microplastics - Primary microplastics and Secondary microplastics.
    • Primary microplastics - Any plastic fragments that are already 5.0 mm in size or less.
    • Secondary microplasticsThey are arise from the degradation (breakdown) of larger plastic products through natural weathering processes.
  • Research findings – They act as ice-nucleating particles that produce clouds in conditions where they would not form.
  • They are suspended in small droplets of water and slowly cooling these droplets to observe how the microplastics affected ice formation.
  • The average temperature at which the droplets froze was 5-10 degrees warmer than droplets without microplastics.
  • They are insoluble as a defect into a droplet, it can nucleate ice at warmer temperatures.
  • They are interacting with the climate system and the process of cloud formation is triggered by microplastics.
  • Clouds effect on weather and climate If microplastics are present, they could cause ice crystals to form, potentially increasing rain or snowfall.
  • They reflect incoming sunlight away from the Earth's surface, which has a cooling effect.
  • They absorb some radiation that is emitted from Earth’s surface, which has a warming effect.
  • If microplastics increase the presence of ice particles in clouds compared with liquid water droplets, this shifting ratio could change clouds’ effect on Earth’s energy balance.

The world is producing 57 million tons of plastic pollution per year.
