田纳西州如何利用废物流映射

田纳西州有数千吨工业废料from numerous manufacturing processes that have monetary value. However, manufacturers don’t have the connections to return that material back to the economy. Tennessee is working to change that by conducting an in-depth study of the types of waste materials produced by the state’s top industries.

In 2014, the Tennessee Department of Environment and Conservation’sOffice of Sustainable Practicessaw an opportunity. By connecting companies located near each other, the department hoped to help facilitate potential opportunities for synergy through waste stream reuse and repurposing. These potential opportunities have become a reality through the Waste Stream Mapping Project, a collaborative effort between the department and the田纳西大学工业服务中心.

The Waste Stream Mapping Project summarizes the waste streams from four manufacturing industry sectors in Tennessee: automotive; building products; food; and furniture. The project resulted in a physical representation of geographic clusters of wastes that helps to quantify waste streams from the four industry sectors and identifies whether they are disposed of in landfills or reclaimed, reused or recycled. Many results of this study were encouraging, surprising and sometimes frustrating.

Unilever is as committed to a sustainable economy as anybody, but there are still some materials that are waiting for a market to develop.

The four industrial sectors, which included a total of 265 companies, do an excellent job of recycling common materials because there are existing markets for paper, cardboard and most plastic. Tennessee’s automotive industry produces 38 percent of the state’s industrial output from nearly 600 automotive manufacturers and suppliers, and recycles at a rate of over 90 percent. Food, furniture and building product manufacturers are not far behind at a recycling rate of just over 70 percent.

这些令人鼓舞的人物在一个具有增长空间的回收基础设施状态。

“田纳西州有30多家公司使用可回收材料作为主要的原料，每天有近8,000名田纳西州的田纳西人在这些公司工作。”东南回收发展委员会, a network of governmental and non-governmental organizations that seeks to develop sustainable recycling solutions for the 11 states in the Southeast.

The council sees potential for further growth in infrastructure for the exchange and reuse of industrial waste materials within Tennessee. Sagar noted, "There are still markets that need improving in Tennessee, like plastics, which often get processed in adjoining states."

According to the Waste Stream Mapping Project research, high-end and high density plastic materials from Tennessee industries often don’t make it back into the Tennessee economy. Other materials such as fabric and some types of oils and rubbers don’t have enough of a viable end-market to justify the logistical issues of transporting the material.

对于想要被指定为零废物的公司而言，具有明显价值的材料通常是挫败感的来源。

Materials with obvious value such as rubber hose trim, phenolic slate and process oils are often sources of frustration for companies wanting to bedesignated as zero-wastewithout diverting materials through waste-to-energy.

"It’s nice to have the option for energy recovery, but I’d rather have a true market of recovery for certain stuff," said Larry Gibson, plant manager of Unilever in Covington, Tennessee. "

该研究的最出乎意料的结果之一是，某些被认为在整个州均匀分布的材料几乎完全集中在一个位置。由于潜在的运输效率，这可能会使市场好用的买球外围app网站在重新利用单个公司或小型地理区域中的一组集群公司产生的单一材料的重新使用。

"One company generates nearly 97 percent of all the spun glass waste in the entire state," said Albert Tieche, solutions consultant with the University of Tennessee Center for Industrial Services and primary administrator for the Tennessee Waste Stream Mapping Project.

According to Tieche, "There’s currently no market [for the glass], but the company is working diligently with us and with the Tennessee Department of Environment and Conservation." Spun glass is a major component of fiberglass insulation, used in the construction industry.

The food sector serves as another example where 85 percent of plastics waste comes from only one facility.

Tieche is quick to point out the positive:"The potential economic impact of recycling the [materials that are currently] disposed [of] … across all four manufacturing sectors is estimated to be a minimum of $11 million with the potential to create between 1,800 and 2,600 jobs." The potential for expansion is tremendous and suggests that good things are coming to Tennessee’s economy and workforce.

The Tennessee Department of Environment and Conservation is working with theU.S. Business Council on Sustainable Development通过在田纳西州创建工业废物交换计划来实施废物流映射项目的结果。商业委员会在丹佛，底特律和俄亥俄州以及德克萨斯州奥斯汀的行业中成功地为行业提供了重新使用市场，该委员会的总部设有其总部。
