Tires are an integral component of automobiles and are manufactured using raw materials such as natural rubber, nylon, tire cord fabric, and carbon black. Rubber chemicals and synthetic rubber, including styrene-butadiene rubber and poly-butadiene rubber, are also used in manufacturing tires. Low rolling resistance tires are essentially green tires and their usage enhances fuel efficiency, vehicle performance, and safety. It also helps to reduce vehicular emissions.

Biodegradable materials are materials that are decomposed naturally through microorganisms. Biodegradable packaging differs from conventional non-biodegradable packaging in terms of raw materials, production technology, applications, and composting. Packaging includes a wide range of materials such as paper, board, plastic, metal, glass, wood, and other materials. Biodegradable materials such as bioplastic and paper are widely used in packaging applications because of their sustainable nature, properties, and appearance. Biodegradable packaging materials are used in all levels of packaging including primary, secondary, and tertiary packaging.

BOPP is a polypropylene film widely used in packaging. Biaxial orientation is a process that involves heating the cast film continuously to bring it to a stretchable temperature, after which the film is stretched in a machine and subsequently drawn in the transverse direction. This process is carried out by tenter and bubble methods. BOPP films are UV resistant and have a smooth surface, good clarity, and excellent chemical and abrasion resistance properties.

As the price of petroleum and material costs escalate and pressures of maintaining the sustainability of our environment, owners must continually find methods to decrease material costs and maximize their benefits. This paper presents the findings of laboratory characterization of HMA mixtures containing high reclaimed asphalt pavement (RAP) content with crumb rubber (CR) additives. Five mixtures were examined in this study. The conventional mixture contained a styrene-butadiene-styrene, polymer-modified asphalt cement, Performance Grade (PG) 76-22M and no RAP. The second mixture utilized 15 percent RAP and PG 76-22M asphalt cement binder. The third mixture contains no RAP, 30 mesh CR additives blended (wet process) with a PG 64-22 binder. The fourth mixture contains 40 percent RAP, 30 mesh CR additives blended (dry process) with a PG 64-22 asphalt cement binder. The final mixture utilized 100 percent RAP with CR additives. Laboratory mixture characterization includes the Asphalt Mixture Performance Tests (Dynamic Modulus, E*, and Flow Number, FN), Semi-Circular Bend test, Dissipated Creep Strain Energy test, and the Modified Lottman test. In addition, Loaded Wheel Tracking, LWT, test was performed. Results indicate that the addition of CR additives as a dry feed to carry rejuvenating agents is promising. Mixtures containing high RAP content and CR additives exhibited similar performance as conventional mixture with PG 76-22M binder.

The Office of Waste Processing, within the Office of Technology Innovation and Development, funded the development of an enhanced Caustic-Side Solvent Extraction (CSSX) solvent for deployment at the Savannah River Site for removal of cesium from High Level Waste. This effort lead to the development of the Next Generation Solvent (NGS) with Tris(3,7-dimethyl octyl) guanidine (TiDG). The first deployment target for the NGS solvent is within the Modular CSSX Unit (MCU). Deployment of a new chemical within an existing facility requires verification that the new chemical components are compatible with the installed equipment. In the instance of a new organic solvent, the primary focus is on compatibility of the solvent with organic polymers used in the affected facility. This report provides the calculated data from exposing these polymers to the Next Generation Solvent. An assessment of the dimensional stability of polymers known to be used or present in the MCU, Defense Waste Processing Facility (DWPF), and Saltstone facilities that will be exposed to the NGS showed that TiDG could selectively affect the elastomers and some thermoplastics to varying extents, but the typical use of these polymers in a confined geometry will likely prevent the NGS from impacting component performance. The polymers identified as of primary concern include Grafoil (flexible graphite), Tefzel, Isolast, ethylene-propylene-diene monomer (EPDM) rubber, nitrile-butadiene rubber (NBR), styrene-butadiene rubber (SBR), ultra high molecular weight polyethylene (UHMWPE), and fluorocarbon rubber (FKM). Certain polymers like NBR and EPDM were found to interact mildly with NGS but their calculated swelling and the confined geometry will impede interaction with NGS. In addition, it was found that Vellumoid (cellulose fibers-reinforced glycerin and protein) may leach protein and Polyvinyl Chloride (PVC) may leach plasticizer (such as Bis-Ethylhexyl-Phthalates) into the NGS solvent.

Flame retardant properties of ammonium polyphosphate (APP) and its two kinds of microcapsules,MFAPP with a shell of MF resin and EPAPP with a shell of epoxy resin,were studied in styrene-butadiene-styrene rubber (SBS).The results indicate that the microencapsulation of APP leads to an increase in LOI in SBS compared with APP.When dipentaerythritol is incorporated into the SBS composites containing APP microcapsules,a further improvement in flame retardancy of the composites is observed.Moreover,thermal decomposition behavior and mechanical properties of the SBS composites are investigated.
