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...

Sorting of plastic waste for effective recycling

Separation of plastic from various types of waste streams represents one of major problematic process in energy recovery through different thermochemical processes. The sorting of plastics is a very essential step in different waste management technique. Manual sorting is suitable when plastic component are present in large amount but it is a labor intensive process. In automated sorting techni...

Feedstock recycling of plastic wastes in cokemaking

The carbonization of coal to produce metallurgical coke is an alternative route for the feedstock recycling of plastic wastes of different structures and origins. Individual plastics or mixed plastics of domestic origin can be incorporated into typical coking blends as secondary raw materials. The effects of the composition of the plastic wastes on the thermoplastic properties of coal, coking p...
