Renewable chemicals presentation final

  1. 1. Renewable Chemicals: Boon or Bane? By Yakindra Prasad Timilsena
  2. 2. Problem statement• Currently around 90% of all organic chemicals synthesized from mineral oil or petrochemicals (IFEU Institut, Heidelberg)• Increase in prices of mineral oils• Mineral oils- non renewable resources• Biomass easily and abundantly available locally• the growing ability of certain microorganisms to yield higher productivity of the desired chemicals
  3. 3. Introduction• Application of industrial biotechnology for the production of chemicals (also called green chemicals) by the use of biomass as a renewable feedstock (i.e. replacing petrochemical feedstocks)- an emerging technology• Area with extensive R&D potential for the development of a renewable feedstock based technology• Engineered microorganisms are being used to synthesize chemicals and polymers that are used in our everyday lives to produce everyday products
  4. 4. Major driving force• Increased consumer consciousness and demand of biobased products• Governmental support for green products that reduce greenhouse gas emissions.• Renewable chemicals also reduce dependence on finite non-renewable petroleum resources• biobased products industry accounts for over 5,700 direct jobs, and is likely responsible for over 40,000 jobs in the united states only.
  5. 5. Why Renewable chemicals• Environmentally benign (Cleaner environment) - greenhouse gas emissions could be reduced by 1.0 -2.5 billion tonnes of CO2 equivalent by 2030 through the development and implementation of biobased products and other industrial biotechnologies (WWF, 2009). - The manufacturing process of bioplastic from renewable feedstock lowers GHG by 50 per cent, compared to the manufacturing process of Nylon 6 from non-renewable feedstock.
  6. 6. Why Renewable chemicals• Sustainable (Better Business) - Depletion of fossil fuel is inevitable• Alternative - Replacement of petrochemicals- reduces dependency - In the US, 8.4 million barrels petroleum per day are used to 1 produce chemicals and plastics (Bio, 2010)• Cheap raw material (Better lives) - Industrial, household and municipal waste materials utilized - also make municipal waste more manageable
  7. 7. Why Renewable chemicals• Reliable• Low cost• Domestic raw materials• Abundant raw materials• 1.3 billion tons of biomass potential in US*• Enough for 165 billion gallons of biofuels (40 x current)• Could theoretically meet 100% of current US gasoline demand of 140 billion gallons per year *U.S. Department of Energy
  8. 8. Why Renewable chemicalsEnvironmental Profile• Bioplastics – Could cut US petroleum consumption by 145 million barrels/year• Compostable: could cut plastics in waste stream by 80%• Cellulosic Ethanol – Could cut US GHG emissions 22% by 2050• Enzyme bleaching - (paper, textiles) textiles)* – Reduces chlorine use by 10-15% – Cuts energy use 40% – Cuts water use 18%•

  16. 16. Fast moving consumer goods (FMCG)• Soaps, cleaning agents and detergents• Cosmetics• Personal care• Paints, varnishes and inks
  17. 17. Biopolymer• The polymer market is currently the strongest area for renewable chemicals. Synthetic bio-based polymers which are biodegradable (polylactic acid, polyhydroxy alkanoate) serve niche markets such as food packaging.• Bio-plastics- carbon neutral as the carbon dioxide is absorbed while growing the sugarcane to offset the carbon released during the production process and during the final decomposition process.• Production typically involves processes such as fermentation, dehydration and polymerization.
  18. 18. Platform chemicals• These building block chemicals have a high transformation potential into new families of useful molecules.• Major investments made in the development of processes to produce renewable intermediates like propylene glycol, succinic acid, 3-hydroxypropionic acid, and ethylene.

  20. 20. Currently most important products• Bioethanol• Amino Acids• Vitamins (e.g. Vitamin C)• Citric Acid• Enzymes (e.g. detergents, food, feed)• Sweeteners (e.g. Aspartame, sugar-alcohols)• Lactic AcidBiomaterials and biopolymers from renewablechemicals are a market reality and have consumerdemand, more so now than ever before.

  30. 30. Scenario of biomass for chemical products Fats and oil Carbohydrates Others (a.o. proteins)10% of the feedstock in the chemical industry (US and Germany, 2000)
  31. 31. Cons views• The strong point against the production of chemicals from biosources especially food crops is taken as a serious crime towards humanity. There are already 1 billion people who are forced to go to bed without food and if food crops are converted to chemicals, it will definitely increase the number of hungry people especially in developing and poor countries.
  32. 32. Cons views• "Soybeans and corn are showing up in carpets, disposable cups, salad bags, candles, lipstick, socks, surfboards, cooling fluid in utility transformers, and even the body panels of Deere & Co. harvesting combines” (Wall Street Journal, 2007).• One of the main cause of hike in price of food grains is the use of food grains for bioethanol and renewable chemical production.
  33. 33. Cons views• "a $3.25 bushel of corn can generate $15 worth of bio- plastic allowing for much greater profit margins than would come from turning the corn into food ingredients or livestock feed.” (Kilman, 2007).• Use of heather and wheat straw for extraction of chemicals lead to shortage of fodder to animals

  43. 43. Cons views• The most worrisome is the impacts on the natural environment. Growing corn to produce ethanol and other renewable chemicals consumes 200 times more water than the water used to process corn into biochemicals (U.S. National Academy of Sciences, 2007).• Use of food crop in biochemical production will impose a pressure on the forest to find more arable land for feeding the growing population
  44. 44. Cons views• “large increases in biofuels production in the United States and Europe are the main reason behind the steep rise in global food prices“ (WB Report, 2008)• Corn is used to feed chickens, cows, and pigs. So higher corn prices lead to higher prices for chicken, beef, pork, milk, cheese, etc.• The grain required to fill a 25 US gallons (95 L) fuel tank with ethanol will feed one person for a year (Brown, 2006)
  45. 45. Cons views• 800 million people are permanently malnourished,• the number of livestock on earth has quintupled since 1950.• Farming crops for chemicals will encompasses mass starvation and the eradication of tropical forests• Use of wood based raw material will lead to cutting down trees for chemicals which enhances the problem of climate change.
  46. 46. Ways Forward• The use of industrial crops for direct large scale chemical production beyond traditional products such as starches, sugars and oils still under development.
