DYNISCO (Franklin, Massachusetts)

www.dynisco.com Contact: Mike Davis, Mike.Davis@dynisco.com

In October 2012, Dynisco introduced the VertexTM mercury-free pressure sensor, which employs a radically different sensing technology. Not only is the sensor significantly safer and friendlier to the environment, it is also a drop-in replacement for existing sensors, with performance that is comparable or better, so barriers to market acceptance are extremely low. VertexTM is a safer product to own and use, and it eliminates hazardous waste and related costs for both users and the manufacturer.

Dynisco has long been aware of the environmental hazards posed by mercury, a key component in most high temperature pressure sensing devices. While mercury used in its devices is strictly monitored and controlled, the best sustainable alternative is to remove mercury altogether. Dynisco is also a staunch supporter of IMERC, the Interstate Mercury Education and Reduction Clearinghouse. Established by environmental officials in eight states in the northeastern U.S., IMERC advocates for laws and programs aimed at getting mercury out of consumer products, the waste stream, and the environment.

For their environmentally conscientious mercury-free sensor, Dynisco is being recognized in “Design for Sustainability” award category.

DEVELOPMENT OF FILAMENTS FOR 3D PRINTING

Ya-Haddy Salla and Travis Walker

Manufacturing and Mechanical Engineering Technology Department, Rochester Institute of Technology (RIT), Rochester, NY 14623

Abstract: 3D printing is a mechanized method of making 3D objects on a machine from a Computer Aided Drafting (CAD) and model on a computer screen. Conventional 3D printing filaments are usually petrochemical-based polymers; ABS is the most common type of filament material. The purpose of this research is to develop new biodegradable hybrid polymer filaments to replace the existing petroleum-based filaments for 3D printing.

The hybrids of biodegradable filaments were made by mixing PLA (polylactic acid) with LDPE (low density polyethylene) using a single screw extruder. Two different ratios of the hybrids were 30 wt% PLA and 60 wt% PLA with LDPE balanced, respectively. No compatibilizer was used in making the hybrid filaments. The extruded hybrid filaments were then tested as per ASTM standards: Tensile testing (ASTM D638), Differential Scanning Calorimetry (DSC, ASTM D3418), Melt flow Index (MFI, D1238) and Thermo-gravimetric Analysis (TGA, E1131). The testing results of the biodegradable hybrid filaments were compared to the filaments of ABS and 100wt% PLA for applications in 3D printing.

The results of the MFI test showed that the MFI of the PLA-LDPE hybrids increased from 5.06 g/10 min. to 7.14 g/10 min. as the weight % of the PLA increases from 30% to 60%, respectively. The data of the tensile testing showed that the tensile strength of ABS filaments were higher than those of the 30% PLA and 60% hybrid-filaments, but the % elongation of the PLA-LDPE hybrids was significantly higher than the ABS filaments. We will report the mechanical and thermal properties of the new biodegradable filaments to replace the petroleum based ABS filaments for 3D printing in the future.

RECYLING PLA PLASTICWARE ON A UNIVERSITY CAMPUS

Waneta Kratz, Robert Michitsch and Aga Razvi

University of Wisconsin - Stevens Point, Stevens Point, WI

Abstract: Municipal solid waste (MSW) management is a costly necessity. Petroleum-based plastics are commonplace in MSW of modern, throwaway societies. Petroleum-based plastics do not breakdown from natural processes in landfills and take up large amounts of valuable space. Compostable plastics offer a sustainable solution to petroleum-based plastics. Polylactic acid (PLA) is a plastic made from 100% renewable resources, is compostable at industrial composting conditions (high heat, high moisture) and also easily breaks down in a recycling process. Published research describing responsible waste management of PLA waste is scarce. This research compares two end-of-life options of PLA: industrial composting and chemical recycling. To test industrial compostability, PLA products were composted in a controlled environment in two separate experiments. The preliminary study shows that PLA composted at 50°C successfully degraded an average of 97% (weight loss) after 120 days, while PLA composted at 40°C did not successfully degrade after 120 days. Compost containing degraded PLA was then applied to plants and physical and nutrient analyses were performed. A more thorough composting experiment was then performed using controlled conditions at 55°C and 60% moisture comparing the degradation effects on 5, 10, 20 and 30 % (by weight) additions of PLA cups vs. paper cups. All PLA treatments degraded over 99% after 12 weeks. Paper treatments did not show consistent breakdown with average weight loss of -19.4, 25.38 and 67.89% for the 5, 10 and 20% treatments respectively. A subsequent germination trial evaluated the effects of this compost on plant growth. Composting of PLA will be compared to chemical recycling of PLA. Industrial rinsing methods for chemical recycling of post-consumer PLA will be assessed. The University of Wisconsin-Stevens Point (UWSP) currently implements PLA plastic ware at dining facilities on campus. Collection for chemical recycling has been implemented, titled the FRESH project, and is being evaluated by the WI Institute for Sustainable Technology. Post-consumer waste from this project is being used to test for industrial rinsing method effectiveness on the lactic acid product resulting from PLA chemical recycling.

Abstract: With the use of conventional plastics today, there comes a multitude of drawbacks, such as the large amount of energy that is required to produce the plastic and the waste that is a result of plastic production and use.  In order to reduce the negative effects of plastics use, it is necessary to examine other sustainable sources of feedstock for plastic production.  One possible source of a feedstock for plastic production is algal biomass:  they do not require arable land in order to be grown and can also be used to remediate contaminated water.  With use of algal biomass, it is possible to produce different types of products, such as sheets and films while at the same time limiting the amount of energy spent and environmental damage incurred.

The research conducted in this poster is the examination of the microalgae species Spirulina platensis and Chlorella vulgaris, and the mechanical and viscoelastic properties of the bioplastics that have been produced from them through the use of compounding and extrusion.  When molded, it was found that the extension and modulus for both Spirulina and Chlorella-based bioplastics decreased when only glycerin is used to plasticize the material.  As for the thermoplastic blends utilized in this research, their static mechanical properties were then compared with models known in the art.  In terms of the plasticizer used, when higher amounts of glycerin are used, the initial modulus decreases, with an increase in the Tan δ initially, as well as more elastic properties at lower temperatures.  This research further Helped to show how these particular biolplastics will change based on the type of microalgal species used, as well as the amount of glycerin utilized as a plasticizer.

Abstract: Bio-based and biodegradable composites are a renewable and environmentally friendly alternative to conventional polymers and their composites. However, many lignocellulose-based biocomposites suffer from a poor polymer-fibre interface and require compatibilisers, chemical treatments, or surface treatments to improve the mechanical and thermal properties of the composite. These are occasionally performed using non-environmentally friendly processes which can drastically affect the after-life biodegradability of the biocomposites.

Biocomposites incorporating polylactic acid and maple hardwood fibres were compounded at various fibre loadings, with and without sequential surface treatments on the maple fibres. All composites were compared in terms of mechanical, thermal, and biodegradation performance with the aim of developing composites with improved mechanical and thermal properties, but also the use of environmentally sound processes to produce or maintain a 100% ‘green’ biocomposite.
