Sorting Plastic Bottles for Recycling

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...

A Goal Programming Approach for Plastic Recycling System in Thailand

Plastic waste is a big issue in Thailand, but the amount of recycled plastic in Thailand is still low due to the high investment and operating cost. Hence, the rest of plastic waste are burnt to destroy or sent to the landfills. In order to be financial viable, an effective reverse logistics infrastructure is required to support the product recovery activities. However, there is a conflict betw...

Fiber reinforced plastic composites using recycled materials

This work investigates the feasibility of using recycled high density polyethylene (rHDPE), recycled polypropylene (rPP) and old newsprint fiber (ONP) to manufacture fiber reinforced composites. The boards were made through air-forming and hot press. The effects of the fiber loading and coupling agent content on tensile, flexural, internal bond properties and water absorption and thickness swel...
