A process that would be a plastics recyclers nightmare may help farmers deal with the disposal of agricultural and domestic plastics by creating burnable, energy-efficient plastic nuggets, according to a Penn State agricultural engineer.
"In plastics recycling there are two unbreakable rules," says James W. Garthe, instructor in agricultural engineering and cooperative extension specialist. "You cannot mix types of plastic, and the plastics must be clean. This process does both since mixed plastics burn just fine and the dirt and debris come out with the coal ash anyway."
Agricultural plastics, such as mulch films, greenhouse films and pots, flats and silage wraps are universally dirty, and the cost of cleaning them before recycling would be expensive. Also, while mulch and greenhouse films are generally low-density polyethylene, nursery pots are polypropylene and soda bottles and milk jugs are polyethylene terephthalate and high-density polyethylene respectively. The plastics found on farms, nurseries and landscape yards are a variety of plastics that would never be mixed in conventional recycling.

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
