Pyrolysis Plants A Solution to Plastic, Rubber, and Oil Sludge Waste.docx

This article explains the cost of building a pyrolysis plant.

1. Pyrolysis Plants: Addressing Plastic, Rubber, and Oil Sludge Waste
The globe is grappling with a severe environmental challenge due to the rising
volumes of plastic, rubber, and oil sludge waste. These materials are hard to get rid of
and threaten the environment. Fortunately, pyrolysis plants provide a way to tackle
this issue by transforming such wastes into valuable outputs like fuel oil, carbon
black, and gas.
1. Waste Plastic
Plastic waste is a significant global environmental concern. Common types of plastic
waste include pure PP/PE/PS plastics, pure ABS plastics, pure white plastic sheets,
food packaging bags, paper mill waste, plastic household trash, and aluminum-plastic
composites. These materials have an oil content ranging from 50% to 95%. However,
PVC and PET are not suitable for processing in pyrolysis plants. Plastic wastes take
centuries to decompose and harm the environment, but pyrolysis plants can process
them into valuable products. Through pyrolysis, plastic waste is broken down into
smaller molecules, which can then be further refined into useful items.
2. Waste Rubber
Waste rubber is another major environmental problem. It comes in various forms:
rubber powder, large car and truck tires, small car, motorcycle, and bicycle tires,

2. conveyor belts, rubber soles, and other rubber products. Typically, rubber has an oil
content of 35% to 52%. In addition to producing fuel oil and carbon black, waste tires
can also yield steel wires, which can be sold directly.
3. Oil Sludge
Oil sludge is a hazardous waste that is tough to dispose of. It is a mixture of oil, water,
and solids generated during oil refining. Oil sludge occupies precious landfill space
and poses environmental risks. This category mainly includes oil sludge, oil sands,
coal tar residues, and drilling muds, with oil content ranging from 20% to 70%.

3. From the above materials, pyrolysis plants produce fuel oil, carbon black, and
combustible gas. Fuel oil can be used in steel mills, boiler heating, heavy oil
generators, and cement plants, or refined into diesel. Carbon black, with its high
calorific value, can be burned or refined for making new tires, shoe soles, and paints.
Combustible gas can be used directly to heat the reactor—saving energy—or for other
heating purposes.
In short, pyrolysis plants offer multiple advantages. First, they reduce the amount of
waste sent to landfills, preserving valuable landfill space. Second, they cut down on
waste incineration, lowering air pollution. Third, they decrease reliance on fossil
fuels, helping to reduce greenhouse gas emissions. Finally, they turn waste into
valuable products, conserving natural resources.
