Biotechnology to expand use of biomass in China

0
Novozymes, a global bioinnovation company based in Denmark, and Dacheng Group, a major starch processing company based in China, announces an agreement to make plastics from agricultural waste. The two companies have agreed to expand their cooperation in developing biochemicals derived from biomass and to promote the industrialization of plant-based glycol. Glycols are biochemicals used in household cleaning products, cosmetics, and used as building blocks for making polyesters and plastics.

Flexible Landfill Cover Uses Flexible Solar Cells

0
The old saying that things are bigger and better in Texas just might apply to landfill management. Republic Services, Inc. has unveiled a 5.6-acre exposed landfill cap with photovoltaic (PV) cells adhered directly to the geomembrane. It's all taking place on a portion of the 680-acre site along Tessman Road in San Antonio, Texas. Firestone manufactured the green-colored geomembrane, and United Solar manufactured the flexible PV laminates.

Does EC Make a Difference?

0
While the term "best management practice" (or, BMP) may be misleading, especially since agencies from town to town may disagree on which BMPs are acceptable--that is, which are actually "best"--erosion control is clearly of need. You can see this on a very large scale around Las Vegas. The Review Journal looks back at 10 years of major erosion control and bank stabilization projects and how sediment loads have been reduced by 75%, 38,000 native plants have returned, more than 100 species have returned, and much more.

Raven Reports 3Q Results

0
Raven Industries released strong third quarter results on Wednesday. The Flow Controls Division continues to perform well while the Engineered Films Division (which includes Raven's geomembrane lines) saw 23 percent growth in third quarter sales. Raw material costs (including the often volatile resin market) pinched some profit, but overall volume was good and high demand in the oil and gas industry for pit and pond liners continued to be one of the company's signature successes.

Bechtel's Blackout in Tennessee

0
A major expansion is under way at the US Department of Energy's Oak Ridge nuclear landfill in Tennessee. In December, Bechtel Jacobs and its subcontractor, ESI, completed installation of a high-density polyethylene (HDPE) geomembrane on a new cell that adds 465,000 cubic yards of disposal space for low-level radioactive waste and other hazardous materials. The total burial volume is now 1.7 million cubic yards. The project team has referred to the approach as a "blackout," because the membrane is black. Learn more here.;

GSE Environmental Seminars Announced for Australia and Virginia

GSE Environmental's "Geosynthetics for Success" Technical Seminar Series returns with two dates in August and another in October. These events bring top-tier speakers together on major engineering topics, new technologies, new designs and more. For attendees, it is an opportunity not only to learn about the latest regulations and engineering approaches but advances in geosynthetic technologies that are helping make some applications possible and others more economical and sustainable. Professional development credits are also available for attendees. In August, the technical seminar series will arrive in Australia, first in Perth (August 7) and then in Brisbane (August 9). In October, the seminar returns to the USA for a session in Chantilly, Virgina. Learn more.

More Unlined Facilities in Kingston?

0
The Tennessee Valley Authority (TVA) was in charge of the unlined, Kingston, Tennessee coal ash storage facility when it broke in December 2008 and released more than 5 million cubic yards of coal ash across a couple hundred acres. Cleanup is expected to cost well more than $600 million. Currently, TVA is construction a gypsum storage pond, but the plans call for only a clay liner. Local officials are pushing for a geosynthetic lining system. Learn more here.;

Bringing a Pond Back

0
Monument Valley Park in Colorado Springs, Colorado once had a beautiful pond. But with the city under budget constraints, management of the pond was suspended. The water slowly drained back into the groundwater, leaving behind an empty pond bed. The city's parks and trails manager is evaluating the possibility of installing an EPDM pond liner, or perhaps some clay, but nothing will be considered until the money is available. It's possible that some late summer rain will relieve the parks of irrigation costs, and if so the money might be available to fix the pond. Learn more here.;

BioDiesel
