Bio-feedstocks, Chemicals and Polymers. Trends, Success Stories and Challenges. KISBP 2012 January 30, 2014.
Presentation Outline Bio materials definitions. Present and Emerging Bio-Feedstock's. Emerging Bio Chemicals and Players. First Generation Bioplastics. Second Generation Biobased Plastics. Bioplastics Growth Projections and Market Trends. Applications in Use Today for Bioplastics.
Basic Definitions for Bioproducts. Biobased Products Must be organic and contain some percentage of recently fixed (new) carbon found in biological resources or crops. Focus on renewable resource based origin. Uses C 14 content measurement. Biodegradable or Compostable Bioplastics Meet all scientifically recognized standards for biodegradability and compostability of plastics and plastic products. Independent of carbon origin-(i.e. Ecoflex, PBS, PLA ). Focus is on end-of-life or disposability.
Common Renewable Feedstocks Sugars: Sugar Beet, Sugar cane, sweet sorghum, corn dextrose. Starches: Corn, Cassava, sorghum, sweet potato, wheat. Oils & Fats : Edible: Coconut oil, palm oil, sunflower seed, soy beans. Non Edible: Castor beans, Jatropha.
Concerns with Existing Feedstocks from Food Crops The Food versus Fuel debate: Food Crops Diversion to Fuels/Plastics Land Use Fertilizer Use Pesticide Use The Ripple Effect Use of GMO's
Biomass Feedstocks Under Consideration Lignocellulose (wood, corn stover, other agricultural residues) Oil seeds (soy, rape/canola, palm, coconut, Jatropha) Microalgae Macroalgae (kelp) Waste: MSW, food processing (cellulosic) Used fats and oils Animal processing wastes (rendering, feathers, hair, manure, etc.)

Projected Biomaterials Trends Bioplastics are still less than 1% of the approximate 240 million tons of plastics in use today.
Sales Trends in Bioplastics 205KT 500KT 1.2MT Jim Lunt & Associates LLC. Projections
Why The Change? Continuing lack of infrastructure for use and disposal of compostable plastics. Compostables performance v durables. Increasing demand for biobased, semi-durable and durable products for household goods, electronics and automotive applications. Increasing interest and developments in existing and new monomers from renewable resources.

Challenges for Bio Materials. Oil pricing continuing to increase. Improved performance/ reduced cost. Composting/recycling infrastructure developments. Expanding from single-use compostable to durable applications. Moving to non-food source feedstocks. Competition from carbon dioxide based plastics. Natural gas dynamics on polyolefin/ aromatics Pricing.
