  12. 12. Petro-Plastic Woes• Non-renewable (geological timeframes to produce but consume in 1 to 10 years)• Generally nonbiodegradable with devastating affects on ocean life 6 times more plastic than plankton by mass• Demand and production skyrocketing• Plastics industry supports more drilling• Recycling and reuse low• Health impacts (polymers differ) Agalita Marine Research Foundation www.sustainablebiomaterials.org
  13. 13. Fossil-Fuel-Plastics & HealthPolymer Common Applications Health IssuesPolycarbonate (PC) baby bottles, sports water can leach out bisphenol A, bottles a hormone disruptorPolystyrene (PS) foam insulation, packaging uses benzene, styrene peanuts, plastic utensils, and 1,3-butadiene. meat trays, egg cartons, Styrene is a neurotoxin take-out containers, and is known to be toxic to single-use disposable the reproductive system. cups PS releases toxic chemicals when burned.Polyvinyl Chloride building pipes, siding, made from the vinyl(PVC or vinyl) membrane roofing, chloride monomer; high flooring, and window chlorine and additive frame; shower curtains, content. Toxic additives beach balls, credit cards, such as phthalate cooking oil bottles softeners leach out. PVC releases dioxin and other persistent organic pollutants. www.sustainablebiomaterials.org
  14. 14. How Exposure to Polystyrene Affects the Human Body  Polystyrene in made from the monomer styrene (vinyl benzene)  Styrene remains present in polystyrene (no polymerization process is 100% efficient)  Styrene = a neurotoxicant and reasonably anticipated to be a human carcinogen  Styrene impairs the central and peripheral nervous systems.  Exposure to styrene in the workplace has also been associated with chromosomal aberrations, thus is considered a mutagen.  Carcinogenic Effects: Proven that it causes cancer in animals, but there are no long- term studies showing that PS causes cancer in humans.“The ability of styrene monomer to migrate from polystyrene packaging to food has beenreported in a number of publications and probably accounts for the greatestcontamination of foods by styrene monomer.” – World Health Organization www.sustainablebiomaterials.org

To avoiddeception, the manufacturer shoulddisclose that the package is not suitablefor home composting. Source: http://ftc.gov/bcp/grnrule/guides980427.h www.sustainablebiomaterials.org
  57. 57. CA AB 1972 and AB 2071• AB 1972 (DeSaulnier)–Solid Waste: Plastic Bags: Food and Beverage Containers (effective 1/1/09) This bill modifies two chapters in current law: one on biodegradable and compostable plastic bags and one on plastic food and beverage containers. In both programs, the sale of an item labeled "compostable" or "marine degradable" is prohibited, unless the item meets specific ASTM Standard Specifications, or in some cases, a standard adopted by CalRecycle. (Chapter 436)• AB 2071 (Karnette)–Plastic Bags: Plastic Food and Beverage Containers: Enforcement (effective 1/1/09) This bill establishes penalties for failure to comply with labeling requirements for compostable, biodegradable, and degradable plastic bags and plastic food and beverage containers sold in California. (Chapter 570) www.sustainablebiomaterials.org
  58. 58. CA Senate Bill 567 The Truthful Environmental Advertising in Plastics Law• SB 567 expands the scope of current California law beyond plastics bags and food packaging to all plastics products.• Approved by Gov.

  59. 59. Bioplastics and Organic Certified Compost• USDA’s National Organics Program ensures credibility of USDA Organics label• One rule requires compost feedstock to be free of non NOP- authorized synthetics• The Organic Materials Review Inst. determines which input products are allowed for use in organic production/processing.• OMRI has ruled that compostable and biodegradable products are not acceptable.• The Canadian Organics program and the European Organics program both accept biodegradable plastic in their feedstock.• BPI is developing and executing a plan to seek NOP approval for use of plastics that meet ASTM D6400 and D6868.• Meanwhile, composters will be bound by restrictions placed on them by certification organizations. www.sustainablebiomaterials.org

  63. 63. Genetically Modified Crops • Can be toxic, allergenic or less nutritious than their natural counterparts • Can disrupt the ecosystem, damage vulnerable wild plant and animal populations and harm biodiversity • Increase chemical inputs (pesticides, herbicides) over the long term • Deliver yields that are no better, and often worse, than conventional crops • Cause or exacerbate a range of social and economic problems • Are laboratory-made and, once released, harmful GMOs cannot be recalled from the environment.

  68. 68. USDA acknowledges biobased is not necessarily betterQ. Are biobased products safer than non-biobased products for me and my family?A. Not necessarily. Read the label fully. <snip>Q. Are biobased products better for the environment?A. They can be. There is an expectation that the increased use of biobased products will reduce petroleum consumption, increase the use of renewable resources, better manage the carbon cycle, and, may contribute to reducing adverse environmental and health impacts.Q. Does a higher percentage of Biobased content mean a product is “better”?A. Not necessarily. There is no guarantee that higher content makes the product perform any better (or is safer for humans or the environment).Q. Why is a life-cycle assessment (LCA) not required for the certification?A. The purpose of this certification and label is to verify the presence of biobased ingredients, and to be explicit in just how much biobased content is incorporated into labeled products. The label is not meant to impart environmental attributes to biobased products; rather it points to biobased content-- agricultural materials, forestry materials, and marine and animal materials. <snip>Source: http://www.biopreferred.gov/files/Label_FAQ.pdf www.sustainablebiomaterials.org
