First, let’s establish that every process must follow normal scientific molding protocol. With pack and hold at zero, the shot should be 95 to 98% full. Temperatures and pressures should be kept as ...

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 ...

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 ...

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 ...

There are essentially three widely used technologies for manufacturing plastic products: Injection molding, extrusion, and blow molding. Injection molding is the most commonly used process for the ...

A new way of chemically recycling single-use plastics might offer an incentive to keep them out of landfills. Ivan Radic via Flickr under CC BY 2.0 New research may offer a way to keep single-use ...

Scientists invent process that converts plastic bottles into paracetamol, which is a common drugstore painkiller used in ...

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 - ...

In the late 1940s, following wartime-driven innovation, the mass production of inexpensive plastics revolutionized American ...

Progress toward a legally binding global treaty on plastics pollution stalled and went into reverse this week. The United Nations Intergovernmental Negotiating Committee meeting in Geneva, Switzerland ...
