Used plastic wrappings and containers make good fuel if incinerated, but are also dumped in huge quantities on landfill sites. Researchers are developing a compostable packaging tape that can be disposed of more cheaply, and ultimately creates less waste.
Companies often have to dig deep in their pockets to get rid of plastic packaging and the adhesive tape that holds it together. It costs about 100 euros to dispose of a metric ton of plastic waste by incineration and about 60 euros if it is dumped at a landfill site. “But there is another alternative – composting – that costs half as much as landfill disposal,” insists Dr. Ulrich Wesselmann, managing director of LogoTape, a company that manufactures self-adhesive tape products.
His company has teamed up with researchers at the Fraunhofer Institute for Environmental, Safety and Energy Technology UMSICHT in Oberhausen to develop an entirely biodegradable packaging tape that, moreover, is made mainly from renewable resources. If oil prices continue to rise and manufacturing costs can be brought down, it will be possible to sell the “organic” packaging tape for about the same price as conventional products.

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
Scientists have discovered that the electrical resistance of a copper-oxide compound depends on the magnetic field in a very unusual way -- a finding that could help direct the search for materials that can perfectly conduct electricity at room temperatur
What happens when really powerful magnets--capable of producing magnetic fields nearly two million times stronger than Earth's--are applied to materials that...
The quality of materials often depends on the manufacturing process. In casting and welding, for example, the rate at which melts solidify and the resulting microstructure of the alloy is important. With metallic foams as well, it depends on exactly how the foaming process takes place. To understand these processes fully requires fast sensing capability. The fastest 3D tomographic images to date have now been achieved at the BESSY II X-ray source operated by the Helmholtz-Zentrum Berlin.
Dr. Francisco Garcia-Moreno and his team have designed a turntable that rotates ultra-stably about its axis at a constant rotational speed. This really depends...
If certain signaling cascades are misregulated, diseases like cancer, obesity and diabetes may occur. A mechanism recently discovered by scientists at the Leibniz- Forschungsinstitut für Molekulare Pharmakologie (FMP) in Berlin and at the University of Geneva has a crucial influence on such signaling cascades and may be an important key for the future development of therapies against these diseases. The results of the study have just been published in the prestigious scientific journal 'Molecular Cell'.
Cell growth and cell differentiation as well as the release and efficacy of hormones such as insulin depend on the presence of lipids. Lipids are small...
