A new process to recycle existing plastics indefinitely and reduce the flood of plastics into landfills is being developed by scientists at the University of California, Berkeley. From sandwich bags ...

Weima America, a Fort Mill, South Carolina-based manufacturer of size reduction equipment for the metal, wood, paper and plastic industries, and the Plastics Industry Association, Washington, have ...

A radical new process “vaporizes” plastic bags and bottles to help make recycled materials. American scientists say the innovative chemical procedure turns ubiquitous waste items into hydrocarbon ...

Erie Pa. — A low-pressure injection molding machine that can use multiple extruders that heat the melt in an electrically heated barrel, then pump the material into the mold gives low shear, lower ...

The injection blow moulding process is a key conventional process that enables the production of hollow plastic parts from a pre-moulded semi-finished piece, commonly referred to as a preform. It ...

Plastics are a victim of their own success, so inexpensive, easy to use and versatile that the world is awash in plastic waste. Now researchers have reported a new method of producing polyolefins -- ...

A radical new process "vaporizes" plastic bags and bottles to help make recycled materials. The innovative chemical procedure turns the ubiquitous waste items into hydrocarbon "building blocks" for ...

Waste conversion. A process that converts end-of-life plastics into carbon nanotubes is the subject of a patent application from Trimtabs Ltd. of Swansea, Wales. The patent application points out ...

Polyethylene plastics -- single-use bags and general-purpose bottles -- are indestructable forever plastics. That also makes them hard to recycle. Chemists have found a way to break down the polymer - ...
