GREEN CHEMISTRY Q&A

GREEN CHEMISTRY Q&A

Top Frequently Asked Questions:

 

  1. Q: What is the food vs fuel debate?
    A: Food versus fuel is the dilemma regarding the risk of diverting farmland or crops for biofuels production to the detriment of the food supply. The biofuel and foodprice debate involves wide-ranging views, and is a long-standing, controversial one in the literature.

  2. Q: So Biofuels aren’t a green solution?? How come?
    A: Evidence of the contribution of biofuel policies to rising and increasingly volatile world food prices, This “led ten international bodies – including the IMF, the World Bank, the FAO and UNCTAD – to recommend in 2011 that G20 governments abolish biofuel mandates and subsidies globally. So far the EU has failed to act on these calls.” Laura Sullivan.
    A: Ex. Half of the corn harvest ending as agrofuel instead of on the plate.
    A: Industrial monoculture landscapes continuously expand and pollute soil and bodies of water with insecticides and fertiliser.
    A: After crops have been processed (fermented, distilled) they are no longer available as feed.

  3. Q: What is Chitin?
    A: Chitin is a biopolymer composed of long acetylglucosamine chains that is produced by many organisms.

  4. Q: Where do you find Chitin?
    A: In the external skeleton of insects, crustaceans and the cell walls of fungi, which makes chitin one of the most abundant polymers on earth.

  5. Q: Why focus on chitin?
    A: We need to create better and more environmentally friendly products for the industries. (To replaces petrochemical source materials)

  6. Q: When used in the textil industry, could it be toxic?
    A: In contrast to other substances such as silver threads, which are incorporated into functional socks, chitosan is non-toxic and biodegradable.

  7. Q: It been said Insects have some effect over microbes, what about their chitin?
    A: YES, but further optimisation work is needed, properties are being achieved, the researchers will transfer this positive antimicrobial effects characteristics of chitosan to textiles.

  8. Q: BSFL fatty acids profile vs common biodiesel feed-stocks?
    A: The comparison of the insect fatty acids profile from the energy insect black soldier fly larvae with common biodiesel feed-stocks showed suitability of the insect for production of biodiesel.

  9. Q: How come, we have not been benefiting from this option?
    A: it is still largely seen as waste, rather than a raw material.
