The Benefits of Using How to Get Fuel Oil from Waste Plastic Pyrolysis

Nowadays, pyrolysis technology is more and more widely used in the waste plastic management instead of landfill or recovery through granulation. Everything has two sides, and let's see what is the general advantage and disadvantage of this plastic pyrolysis oil technology in the following article.

Pyrolysis technology converting plastic to oil

Advantages of using pyrolysis technology to convert plastic to oil:

1. High efficiency

Pyrolysis technology is suitable for almost all kinds of waste plastic except PVC and PET, no matter if it is clean or unwashed and unsorted. For a batch waste plastic pyrolysis plant, there is even no need to do the shredding work. All the processes from plastic to fuel oil are carried out inside the waste pyrolysis reactor together with its accessory system, very convenient and man-power saving.

2. Resource Recover

Pyrolysis plant allows for the recovery of valuable resources from plastic waste, such as fuel oil, carbon black, and combustible gas. This helps in reducing the dependence on fossil fuels and conserving natural resources.

(1)The obtained plastic oil is a good heating fuel for heavy industries, such as boiler heating factories, heavy oil power plants, steel factories, cement factories, glass factories, etc. And it can also be refined into diesel fuel for further uses.

(2)The carbon black can be briquetted by heating or refining for further uses. You can also sell it directly.
(3)Syn-gas can be directly used for heating waste plastic pyrolysis plant, saving machine operation cost.

3. High profit

(1)Economic benefits

Waste plastic such as PE(polyethylene), PP(polypropylene), PS(polystyrene) and ABS, etc. has higher oil yield above 50%, which means from the above 10ton waste plastic, you can extract at least 10tonx50%=5ton pyrolysis fuel oil. And the waste plastic is cheap and easy to collect. Some governments even publish policies and give subsidies for developing waste plastic recycling projects. It is a process to convert waste into new energy, so this project is absolutely profitable.

(2)Environmental benefits

Converting plastic waste into oil via pyrolysis plant can help in reducing greenhouse gas emissions and environmental pollution associated with plastic waste. It provides an environmentally friendly method of waste management.

Disadvantage of using pyrolysis technology to convert plastic to oil:

1. High Initial Investment

Setting up a waste plastic to fuel oil pyrolysis plant requires a substantial initial investment. This includes the cost of acquiring land, machinery, obtaining licenses, and complying with safety and environmental regulations. It will take time, effort, and capital.

2. Technical Complexity

Plastic to oil pyrolysis technology requires skilled personnel to operate and maintain the equipment. Technical expertise and intelligent monitoring are necessary to ensure efficient operation and optimum product quality.

From a comprehensive comparison, the advantages of using pyrolysis technology to convert plastic to oil outweigh the disadvantages. Plastic to oil pyrolysis technology is very good, but you need to be careful to choose the right pyrolysis plant supplier. High-quality suppliers can help your plastic pyrolysis project achieve twice the result with half the effort.

Only a fraction of discarded plastics are recycled

The current state of plastics recycling is a significant challenge to our environment and society. Even though plastic is one of the most pervasive materials used in modern life, only 9.1% of all plastics in the US are ever recycled. Of this, most plastic waste ends up in landfills or incinerators, which can take centuries to break down. Moreover, due to the wide variety of different types of plastics present in waste streams, recycling facilities typically extract only high-value plastics for reuse. This means that re-processing techniques such as pyrolysis are required for lower-value plastic waste recycling.

The Pyrolysis process is particularly effective for waste plastics that may otherwise be difficult or impossible to recycle. This process converts these plastics into valuable chemicals and fuels, providing a viable pyrolysis solution for their reuse or disposal in an economically and environmentally responsible manner. Ultimately, pyrolysis can offer a sustainable way of managing plastic waste to reduce its impact on our environment while also providing a profitable opportunity for businesses. Although this process has a promising future, it's not without challenges, particularly regarding technology.

Unique challenges of pyrolysis recycling

Varied economical and technological challenges of pyrolysis.

Pyrolysis challenges are diverse and varied, with each one presenting unique difficulties. Difficulties include:

• Challenging fluids
• Corrosion and fouling
• Environmental factors
• Economics
• Scalability
• Water management

These issues are important for pyrolysis recycling facilities to address to ensure success of their operations. It is also important to know what solutions are available to these challenges.

Corrosion and fouling

Corrosion and fouling are constant challenges in pyrolysis processing due to the acidic, oxygen-sensitive nature of pyrolysis oil. Its corrosive effects damage process equipment beyond repair. Furthermore, co-processing with contaminants like calcium, sodium, iron and magnesium lead to heavy fouling in catalysts and other process equipment. These issues lead to the need for costly replacements. But this goes beyond the cost of the equipment itself. Unreliable equipment causes disruptions in operations. Ultimately, this downtime is an additional cost. Regular maintenance reduces the need for replacements, but frequent maintenance can also be an issue, again costing time and money.

Financial implications

Although pyrolysis is promising in managing environmental waste, the process often comes with substantial financial considerations. The cost of consistent feedstocks, cost-effectively upgrading pyrolysis oil and making pyrolysis oil production competitive against combustion are economic challenges all operations face. The availability and cost of feedstock vary greatly, making accurate forecasting of ROI challenging. To reduce both CAPEX and OPEX costs and make it more affordable for businesses to install within existing footprints, py-oil producers must make intelligent process integrations throughout the value chain. Modularization is one solution but still challenging as modularized solutions are only now beginning to become available, limiting options. Although subsidies and incentive availability will improve as the process matures, the current lack of subsidies or incentives is a definite barrier, as there needs to be more to offset the financial burdens. These economical challenges make breaking into the market unfeasible, raising questions about its long-term viability.

Scalability of operations

The demand for products derived from the pyrolysis of plastics is very high. Yet, suppliers cannot meet these demands due to the limited availability of consistent feedstock, limited technology for the industry and the high costs of both. Tight timelines further complicate this scalability challenge for launching new technologies, limited space for expansion in most plants and a need for flexible solutions that are only sometimes available. Ultimately, this has led to a situation where the sustainability of plastic chemical recycling operations is at risk before it even gets started. These challenges negatively impact production rates, energy consumption, waste management and budgeting.
