Waste Plastic Conversion into Chemical Product Like Naphtha

Catalytic conversion of waste low density polyethylene into fuel oil

Waste Low density polyethylenes (LDPE) represent a source of energy and valuablechemicals, were pyrolysed catalytically in a batch reactor under atmospheric pressure. Calciumcarbide was used as a catalyst to explore its effect on pyrolysis product distribution. The effect oftemperature, amount of catalyst and time on the yields of the pyrolysed products wasinvestigated. The effect of catalyst o...

Turning Waste into By-Product

This paper studies how the conversion of a waste stream into a useful and saleable by-product affects a firm’s optimal operating strategy. We determine whether local implementation can be optimal, i.e., continuing business-as-usual to produce the original product and merely converting the collaterally generated waste stream into by-product, or whether global implementation – that re-optimizes t...

Environmentally Harmful Low Density Waste Plastic Conversion into Kerosene Grade Fuel

Plastics wastes from a municipal solid waste (MSW) plant have a high-energy content and are suitable for fuel generation. Thermal cracking is one of the possible ways to obtain petrochemical feedstock from polymer wastes. Municipal waste plastic of LDPE conversion to kerosene grade fuel experiments were carried out under atmospheric conditions at temperatures between 150 ̊C and 420 ̊C. Low densit...

Microwaves and microbes turn household waste into biodegradable plastic

Marine pollution. Plastic waste inputs from land into the ocean.

Plastic debris in the marine environment is widely documented, but the quantity of plastic entering the ocean from waste generated on land is unknown. By linking worldwide data on solid waste, population density, and economic status, we estimated the mass of land-based plastic waste entering the ocean. We calculate that 275 million metric tons (MT) of plastic waste was generated in 192 coastal ...
