On average, a bottle of water, what do Americans collectively use 2,500,000 plastic bottles every hour.1 you do with the bottle? Few of these bottles are recycled or reused. Many of the plastic Throw it away? It has to go bottles that you use today somewhere.

We use stores, restaurants, businesses, plastics for so many things. research labs, and many other places. Just look around for a It’s not realistic to eliminate minute and you’ll see how many things are made of plastic! the use of it completely. That’s why it’s important Some types of plasticS degrade faster than others, but depending to find solutions such as on the type of plastic, it may never break down. Much of it goes biodegradable plastics to landfills, where trash gets buried under ground between and make the choice to layers of dirt. Other plastics end up littering our planet. You use them as sustainably as have probably seen it on the side of the road, in water ways, and possible. sometimes even on a hike in the middle of the woods. This is becoming a huge problem for our environment and our wildlife because it can be very detrimental and destroy habitats for ourselves and other organisms. One great example of this type of pollution is known as the Great Pacific Garbage Patch. It’s a massive body of trash (mainly plastic) located in the middle of the ocean, 1,000 miles away from land. But how did it get there? Most rivers and streams eventually empty into the ocean. When these waterways are polluted, it all flows into our oceans and begins to build up. 1 Fantastic Bioplastic The ocean’s currents can Get With the Lingo force garbage pollution into certain areas, creating other patches of trash as well.

  • Extrusion Foaming of Bioplastics for Lightweight Structure in Food Packaging
    EXTRUSION FOAMING OF BIOPLASTICS FOR LIGHTWEIGHT STRUCTURE IN FOOD PACKAGING A thesis submitted for the degree of Doctor of Philosophy by Sitthi Duangphet School of Engineering and Design Brunel University December 2012 i Abstract This thesis reports the systematic approaches to overcome the key drawbacks of the pure PHBV, namely low crystallisation rate, tensile strength, ductility, melt viscosity, thermal stability and high materials cost. The physical, mechanical, thermal, and rheological properties of the pure PHBV were studied systematically first to lay a solid foundation for formulation development. The influence of blending with other biopolymers, inclusion of filler, and chain extender additives in terms of mechanical properties, rheology, thermal decomposition and crystallization kinetics were then followed. Creating lightweight structures by foaming is considered to be one of the effective ways to reduce material consumption, hence the reduction of density and morphology of PHBV-based foams using extrusion foaming technique were studied comprehensively in terms of extrusion conditions (temperature profiles, screw speed and material feeding rate) and the blowing agent content. The material cost reduction was achieved by adding low-cost filler (e.g. CaCO3) and reduction of density by foaming. The thermal instability was enhanced by incorporation of chain extender (e.g. Joncryl) and blending with a high thermal stability biopolymer (e.g. PBAT). The polymer blend also improved the ductility. Adding nucleation agent enhanced the crystallization rate to reduce stickiness of extruded sheet. The final formulation (PHBV/PBAT/CaCO3 composite) was successfully extruded into high quality sheet and thermoformed to produce prototype trays in an industrial scale trial. The effect of the extrusion conditions (temperature profiles, screw speed and material feeding rate) and the blowing agent content are correlated to the density reduction of the foams.

  • Biodegradable Packaging Materials from Animal Processing Co-Products and Wastes: an Overview
    polymers Review Biodegradable Packaging Materials from Animal Processing Co-Products and Wastes: An Overview Diako Khodaei, Carlos Álvarez and Anne Maria Mullen * Department of Food Quality and Sensory Science, Teagasc Food Research Centre, Ashtown, Dublin, Ireland; [email protected] (D.K.); [email protected] (C.Á.) * Correspondence: [email protected]; Tel.: +353-(1)-8059521 Abstract: Biodegradable polymers are non-toxic, environmentally friendly biopolymers with con- siderable mechanical and barrier properties that can be degraded in industrial or home composting conditions. These biopolymers can be generated from sustainable natural sources or from the agri- cultural and animal processing co-products and wastes. Animals processing co-products are low value, underutilized, non-meat components that are generally generated from meat processing or slaughterhouse such as hide, blood, some offal etc. These are often converted into low-value products such as animal feed or in some cases disposed of as waste. Collagen, gelatin, keratin, myofibrillar proteins, and chitosan are the major value-added biopolymers obtained from the processing of animal’s products. While these have many applications in food and pharmaceutical industries, a sig- nificant amount is underutilized and therefore hold potential for use in the generation of bioplastics. This review summarizes the research progress on the utilization of meat processing co-products to fabricate biodegradable polymers with the main focus on food industry applications. In addition, the factors affecting the application of biodegradable polymers in the packaging sector, their current industrial status, and regulations are also discussed.

    LITERATURE REVIEW & INVENTORY Greenhouse Gas Impacts of Disposable vs Reusable Foodservice Products JANUARY 2017 T STOP WASTE BEFORE IT STARTS Acknowledgements This study was written by Bill Sheehan, Ph.D. with supervision, review and input provided by Clean Water Fund staff, Miriam Gordon and Samantha Sommer. This project has been funded in part by the United States Environmental Protection Agency under assistance agreement X99T38501 to Clean Water Fund. The contents do not necessarily reflect the views and policies of the Environmental Protection Agency, nor does mention of trade names or commercial products constitute endorsement or recommendation for use. Clean Water Fund thanks the Roy A. Hunt Foundation for supporting this work. T STOP WASTE BEFORE IT STARTS ReThink Disposable, created and implemented by Clean Water Fund (CWF), works in partnership with municipal stormwater and zero waste programs to engage food businesses and institutions (academic and corporate campuses) and consumers to minimize disposable take-out food and beverage packaging at the source to reduce plastics and trash that pollute our waterways and the ocean. This award winning program takes a pollution prevention approach to the ever-increasing problems of solid waste and marine debris. Based on research CWF conducted with five San Francisco Bay Area local jurisdiction partners in 2011, ReThink Disposable learned that food and beverage packaging is the primary component of trash (67%) entering the San Francisco Bay and polluting local creeks. Since 2012, ReThink Disposable has worked with more than 100 food businesses and five corporate and university campuses to reduce over 150,000 pounds of waste and the use of over 15 million disposable packaging items from food service operations, each year.
