Sorting Plastic Bottles for Recycling

High Reliability Plastic Packaging for Microelectronics

This Laboratory Directed Research & Development (LDRD) project conducted in fiscal years 1996 and 1997 under case 3526.030 was devoted to the development of test structures and associated measurement methodology for assessing the reliability of plastic encapsulated microelectronic devices. The end goal was the conceptual specification of one or more Assembly Test Chips (ATCs) which could be use...

Near Hermetic Air Cavity Plastic Packaging for

This paper will detail the design and manufacturing elements of near hermetic air cavity packages produced by injection molding of low moisture diffusivity polymers. The R-Pak process uses a patented sealing methodology to take maximum advantage of the properties of the starting polymeric material. The material properties and advantages will be presented. The very low moisture diffusivity of th...

Facing the Plastic Bottleneck: Rethinking Recycling

In order to gain a frame of reference for the current and future state of solid waste generation and treatment, trends pertaining to the use and disposal of plastics were analyzed to project plastic waste for the next decade. By extrapolating per capita plastic waste data, a logistic function was fitted to suggest that the annual per capita value is headed to stabilize at 94.97 thousand tons. W...

Recycling Techniques of Polyolefins from Plastic Wastes

Disposing of plastic wastes to landfill is becoming undesirable due to legislation pressures, rising costs and the poor biodegradability of commonly used polymers. In addition, incineration meets with strong societal opposition. Therefore, recycling either mechanical or chemical, seems to be the only route of plastic wastes management towards sustainability. Polyolefins, mainly polyethylene (LD...
