Pollution Prevention Advisory BoardAdvanced Technology Grant ProgramANNOUNCEMENT: Due to the passage of HB 1018 (Waste Tire Program), the Advanced Technology Grant Program ended on June 30, 2010. Grants listed below will continue until their projects are completed.The Advanced Technology Grant (ATG) Program is intended to fund research that will increase or improve recycling techniques and technology; create marketable uses for discarded materials, including but not limited to, strategies pertaining to waste tires; address problems caused by inappropriate disposal of solid waste materials, including but not limited to, waste tire stockpiles; and, make use where possible of the research capacities of Colorado institutions of higher education. Fiscal Year 2011 grants are listed below. Grants began February 1, 2010 with project time lines up to 24 months.Colorado State UniversityProject Title: Feasibility Study for Highway Traffic Noise Barriers from a Spray Dryer Ash and used Rubber Composite ($91,374) Flue gas desulfurization in new coal combustion power plants is required by the Clean Air Act to combat the effects of acid rain. The Rawhide Power Station, managed by the Platte River Power Authority (PRPA) in Northern Colorado, uses this process. One by-product of the extraction mechanism results in the production of spray dry absorber material known as spray dryer ash (SDA). Eventually, all coal burning power plants in Colorado and the entire United States will be required to use this procedure to maintain a clean environment. In 2007 approximately 3.5M tons of SDA were produced in the U.S. and it is estimated that 18M tons will be produced by 2017. Currently, only 8.3% of SDA is put to beneficial use with most of that utilized in the mining industry. One positive aspect of the production of this material is that the SDA has many properties that are similar to fly ash, which is widely used in a number of different applications. The negative aspect is that its chemical makeup is such that it is not covered by any of the standards and specifications for fly ash usage in engineering materials, and therefore the SDA produced locally typically finds its way to landfills in the state of Colorado. The investigators have worked with SDA for several years and have had numerous discussions with commercial and municipal agencies about the broad range of applications and products that can be developed using this product. This project will do an extensive feasibility study to engineer highway traffic noise barriers from a combination of SDA and rubber from used car tires, both normally disposable products, focusing on (1) durability; (2) structural aspects; (3) acoustics; and (4) aesthetics. University of Colorado-DenverProject Title: Beneficial Use of Waste Tires for Concrete Production in Colorado ($103,285) This project is a research study that will examine the reuse potential of crumb rubber "recycled tires" in concrete production in Colorado. Specifically, the effects of low and high volume sand replacement with crumb rubber on concrete properties will be determined. The sand component within concrete will be replaced in 10% increments up to 50% (replacement rates of 10%, 20%, 30%, 40%, and 50% crumb rubber) and 25% increments thereafter (75% and 100% crumb rubber). The concrete compressive strength, flexural strength, permeability, and freeze/thaw resistance will be tested in order to determine an optimum sand replacement with crumb rubber. In addition, leaching tests will be performed on the crumb rubber concrete to determine whether any hazardous materials are leached from the material. The primary objective of this research study is to determine the maximum amount of sand replacement with crumb rubber in concrete mixtures without compromising the structural integrity of the concrete. Once a maximum replacement rate is determined, additional mixtures will be evaluated that incorporate partial replacement of the cement, rock, and sand with fly ash, recycled concrete aggregate, and crumb rubber respectively. Roofs To RoadsProject Title: Recycled Asphalt Shingle and Ground Tire Rubber Paving Research Project ($168,235) For the Roofs to Roads experimental paving project using Recycled Asphalt Shingles (RAS) and Ground Tire Rubber (GTR), we will partner with CSU Fort Collins’s Department of Construction Management, Boulder County Transportation Department (BCTD), Parkland Homeowners Association (PHA), Asphalt Specialties (ASCI) and Modified Asphalt Solutions (MAS), to research the performance of RAS/GTR pavement. Our goal is to compare the performance of conventional asphalt pavement to pavement incorporating asphalt from waste asphalt shingles, ground rubber from waste tires, and recycled asphalt pavement (RAP). The project’s goal is the development of Colorado-specific construction and materials specifications for RAS/GTR asphalt that will both ensure long-term pavement performance and promote the continued use of RAS/GTR. To this end, our research project will develop initial guidelines and best practices for construction of RAS/GTR pavements, for use by Colorado counties, cities, towns, and municipalities. The project’s objectives include: 1) promote increasing landfill diversion and recycling of Colorado’s roofing and tire waste; 2) conduct two years of side-by-side performance testing of RAS/GTR pavements for ease of installation, durability, performance, wear and life-cycle; and 3) implement a proven alternative asphalt pavement technology, successfully used in other states, as an immediately marketable and industry-ready product in Colorado. City of Colorado SpringsProject Title: Taking Testing to the Next Level: Pavement Condition Analysis, Sound Study, and Materials Testing of Terminally Blended Tire Rubber Asphalt (TBTRA) Test Sections in Colorado Springs ($85,953) The City of Colorado Springs’ Terminally Blended Tire Rubber Asphalt (TBTRA) Test Section Program has been on-going since 2006. The primary goals of this program are to extend road life on city streets, while increasing safety, lowering road noise, recycling Colorado waste tires, and demonstrating the viability of this product for use in Colorado’s unique, high-altitude climate. Testing is a key factor in the successful documentation and research of this product. Specifically, the testing program includes regular pavement quality analysis, sound studies to track baseline noise levels and their degradation over time, and materials testing to ensure quality test sections are being placed for long term comparisons. City & County of DenverProject Title: Increasing Residential Organics Waste Diversion in the City & County of Denver ($186,936) The grant will continue the current residential composting collection pilot program for an additional nine months. The project will capture additional seasonal data on the organics waste stream, gather more accurate participation data, and test some alternative transportation and processing methods. The City will partner with A1 Organics to test the feasibility of pre-processing organic material (increasing density and minimizing air space) in Denver prior to transporting the material to A1 Organics’ Keenesburg composting site. This continued pilot will provide data unprecedented in Colorado to support permanent implementation and includes expected diversion rates, public acceptance, staffing needs, operational needs (including route sizes, number of trucks, residential carts needs, public education, contamination limits, etc.), and the value of pre-processing materials, transportation and other costing information. Immediate environmental and economic benefits are waste diversion, job creation, new data on organics diversion that can be extrapolated throughout Colorado, and participant education. Final implementation of a citywide service will create jobs, actively spur growth of Denver’s composting infrastructure, divert waste from landfills, and create compost (that will reduce water use, positively impact local food production and more). Colorado Association For Recycling (CAFR)Project Title: Electronics Devise Recycling Task Force ($24,737) The grant is to fund the Electronics Devise Recycling Task Force, through HB-1282, which will develop legislation for handing disposal of electronic devises in Colorado. The task force will research other state laws and hold public meetings for input regarding concerns and issues from local government, non- and for-profit entities, and the general public regarding the benefits and consequences of establishing a landfill disposal ban for electronic devices. The intent is to collect as many electronic devices as possible for refurbishment and/or recycling so that the toxic elements in them are not released into a landfill environment, which in turn may at some point be released in soil, water and air. Fiscal Year 2009 grants are listed below. Grants began February 1, 2009 with project time lines up to 24 months.3R Roofing LLCProject Title: Roofs to Roads ($59,300) In partnership with Boulder County’s Transportation Department, Architects Division, and Resource Conservation Division, 3R Roofing LLC will investigate the feasibility of bringing Recycled Asphalt Shingle (RAS) technology to Colorado. This will be achieved through a demonstration project that will compare conventional asphalt to asphalt with 5% RAS shingles from tear-offs at up to three paving installations in Boulder County. The Colorado Department of Transportation (CDOT) Research Division has expressed significant interest in this technology and will provide technical assistance to this project. A Colorado hot mix asphalt (HMA) contractor, Asphalt Specialties of Erie, Colorado, will provide an accumulation and processing site, and will make available a new RAS grinder they have recently purchased for this project. San Luis Valley Resource Conservation & Development Council*Project Title: Combined Sanitation District for Recycling and Diversion of Municipal Solid Wastes in the SLV ($46,915) The project objective is to take a waste or waste stream that is currently non-productive or even potentially harmful to the environment and convert it into products that are marketable. Currently 90% of municipal wastes are deposited in the local landfills. The recycling processes will take place within the San Luis Valley Sustainable Environmental and Economic Development Park (SEED Park), which is designed to address specifically the economic needs of the San Luis Valley (SLV) and create 100 or more livable wage jobs based on enterprises that are sustainable in this high desert region. * Contract was terminated in July 2009 due to SLV no longer wanting to continue the project. Skumatz Economic Research AssociatesProject Title: Getting the MOST from Colorado's Existing Recycling Programs and Infrastructure - Best Management Practices (BMP) in Education as the CHEAPEST and Most Efficient Technology/Technique to Increase Recycling in Colorado ($49,983) The project aims to deliver more recycling tons for the same money by making better use of existing outreach expenditures – increasing recycling for "free", sustainably, and with NO NEW ROUTES OR CAPITAL. About 90% of Colorado residents already have curbside or drop-off recycling. Getting MORE from the programs that exist – using well-designed social marketing technology / techniques – may be the cheapest and most cost-effective way to dramatically increase Colorado’s recycling rate. Most importantly, these approaches are completely transferable to other Colorado communities, can increase recycling AND bring source reduction and composting into the fold, and do it inexpensively. University of Colorado-DenverProject Title: Trash to Treasure: Using Crumb Rubber from Recycled Tires for Stormwater Pollution Control ($96,660) University of Colorado-Denver proposes a promising market to turn this trash into treasure: Using crumb rubber, a tire-derived material, in granular media filters to treat stormwater runoff. Because stormwater runoff carries sediments and contaminants that degrade aquatic habitats and impair water supplies, Colorado requires stormwater to be treated to the maximum extent practicable. Crumb rubber has been used successfully to filter treated sewage, and has the potential to remove suspended solids, organics, nutrients, and pathogens, which are also main concerns in stormwater runoff. This proposal outlines a series of laboratory experiments to determine the safety and effectiveness of crumb rubber filters, a market research plan to estimate the demand for crumb rubber filters, and a technology transfer plan to disseminate results to researchers, business, and government. Colorado Department of TransportationProject Title: Use of Waste Tires (Crumb Rubber) on Colorado Highways ($300,000) The Colorado Department of Transportation (CDOT) will evaluate the feasibility of using waste tires (crumb rubber) in the construction of asphalt pavements. As part of the evaluation, CDOT will build two pilot test sections and a control section using the Superpave Performance Grade, PG 64-28 asphalt binder in dense graded hot mix asphalt (HMA). The two pilot test sections will be built with crumb rubber modified (CRM) asphalt mix using the wet method (crumb rubber is first reacted with asphalt binder in an open system plant before mixing with the aggregates) and the terminal blend method (a special form of the wet process in which reaction takes place in a closed system plant). The ultimate goal of the research project is to develop applicable Colorado-specific materials and construction specifications for rubberized asphalt that will ensure long-term pavement performance and at the same time promote the continued use of CRM. Also, the research project aims to develop guidelines and best management practices for the construction of rubberized asphalt pavements that the local government entities including counties, cities, towns, and municipalities may use as appropriate. This project will end in 2014. Fiscal Year 2008 grants are listed below. Grants began February 1, 2008 with project time lines up to 24 months.Colorado Department of TransportationProject Title: Feasibility and Plan for Building the Best Practical Noise Mitigation Walls Utilizing Waste Tires along CDOT Highways ($160,000) Colorado State UniversityProject Title: Field Construction of Expansive Soil Rubber Mixtures for Civil Engineering Applications ($149,320) Green Giant RecyclingProject Title: Creating Engineered Structural Building Components from Laminated Oriented Strand Board that has been diverted from Landfill Waste Stream ($72,100) University of Colorado-DenverProject Title: Recycling Solid Waste into High Performance, Environmental, Structural Insulated Panels ($240,245) University of DenverProject Title: Promoting Rubberized Asphalt and Other Scrap Tire Products in Colorado ($96,601) Engineered Vinyl ProductsProject Title: Noise Mitigation Walls Using Recycled Tires on 6th Avenue Frontage Road ($244,000) University of Colorado-BoulderProject Title: Premixed Rubberized Insulation Mortar ($133,929) If you have any questions about these projects or this grant program, please e-mail
