New Technique Converts Plastic Waste to Fuel

Very little this waste is recycled, and close to 80 percent of it sits in landfills or in the natural environment, where it harms wildlife, leaches harmful chemicals, and emits greenhouse gases. Nearly a quarter of all plastic waste is polypropylene, used to make things like food containers, bottles, pipes, and clothing.

How coal can be saved from a global meltdown < Coal Fire

The problem with plastic waste is that it's a by-product of a process called bleaching. When a plastic product bleaches, the chemical reaction produces a chemical compound called methylene chloride, which is then released into water. This is a by product of a chemical reaction that occurs in the coal plant.

What You Should Know About Metallurgical Coal

Metallurgical coal, also known as coking coal, is used to produce coke, the primary source of carbon used in steelmaking.

What is Activated Carbon and How is it Made?

A carbonaceous source, which can exist as coal, peat, or any organic carbonaceous material is carbonized, which means the pure carbon is extracted by a heating method known as pyrolysis. Once the material is carbonized, it needs to be oxidized, or treated with oxygen, either by exposure to CO2 or steam, or by an acid-base chemical treatment.
