Plastic is everywhere, and so is the resulting plastic waste. Oil companies have touted recycling to sell more plastic, but an England-based company, Recycling Technologies, has produced a refinery machine, the RT7000, that can convert plastic into oil. This process, called pyrolysis, involves thermochemically breaking down plastic waste at temperatures above 350 degrees Celsius. This causes the plastic to physically melt and change its chemical composition, reverting to boiling liquid and eventually gas. As the gas escapes, it enters a separate container filled with water, which cools it down and converts it into oil. This oil can be further processed to produce diesel, kerosene, and gasoline. Other companies, such as OMV with their ReOil solution, and the Niutech Environment Technology Corporation, have also developed similar technologies to turn plastic back into oil.

Pyrolysis: Plastic-to-oil conversion method using high temperatures
Pyrolysis is a process that uses high temperatures to convert plastic back into oil. It works by thermochemically breaking down the plastic at temperatures above 350 degrees Celsius in the absence of water. This causes the plastic to physically melt and changes its chemical composition, reverting it into a boiling liquid and eventually a gas. As the gas escapes, it is funnelled into a separate container filled with water, which cools it down and converts it back into oil. This oil can be burned as-is or processed further to produce diesel, kerosene, and gasoline for use in vehicles, stoves, and more. While the process is not the most energy-efficient, it is still beneficial as 1 kg of plastic can produce around 1 L of oil, whereas burning the same amount of plastic would release 3 kg of CO2.
One company utilising pyrolysis is OMV with their ReOil solution. ReOil has achieved a conversation rate of 86% of waste plastic into fuel, with approximately 1 gallon of fuel extracted from 8.3 lbs. of plastic. The process requires minimal energy as the machine uses its own off-gases as fuel, and the water used for cooling remains uncontaminated. In addition to diesel, the processor can also produce petroleum distillate, naphtha, petcoke, and off-gases.
Another example is the Niutech Environment Technology Corporation (Jinan Eco-Energy Technology Co., Ltd) in China, which has developed the Industrial Continuous Waste Plastic Pyrolysis Production Line. This process uses low-temperature catalytic pyrolysis in safe, environmentally friendly, and highly efficient conditions. The technology has been commercialised in several countries, including Germany, Estonia, Thailand, and Taiwan, and has been shown to improve oil yield rate and quality while prolonging the lifetime of equipment.
Pyrolysis offers a promising solution to the problem of plastic waste by converting it into a valuable resource. While it may not be perfect in terms of energy efficiency, the process can help reduce the environmental impact of plastic by recovering valuable oil that can be used for fuel and other applications.

ReOil: OMV's solution to convert plastic waste into fuel
Plastic waste is a pressing global issue, and with plastic being made from oil, it seems logical to convert waste plastic back into fuel. This is exactly what OMV has done with its ReOil solution.
ReOil is a process that converts plastic waste into fuel. It works by thermochemically breaking down the plastic at temperatures above 350°C in the absence of water. This melts the plastic and changes its chemical composition, turning it into a boiling liquid and then gas. As the gas escapes, it is funnelled into a container of tap water, which cools it down and converts it into oil. This oil can be used as fuel or further processed to produce diesel, kerosene, or gasoline for vehicles or stoves.
The process is not the most energy-efficient, but it offers a way to complete the life cycle of plastic. For every 1 kg of plastic, around 1 litre of oil can be produced. This is a much better outcome than burning the plastic, which releases 3 kg of CO2. ReOil's process has a high conversion rate, turning 86% of waste plastic into fuel, with approximately 1 gallon of fuel extracted from 8.3 lbs of plastic.
The ReOil solution has been so successful that a larger plant was built in 2018 with 20 times the capacity of the previous one. This plant continues to produce high-quality fuel, and the process has been commercialized in several countries, including Germany, Estonia, Thailand, and Taiwan. With companies like OMV leading the way, we can address the global plastic waste problem and create a more sustainable future.

Misleading recycling claims: Oil companies touted recycling to sell more plastic
Plastic is made from oil, and it is possible to convert plastic back into oil. Pyrolysis is a process that involves thermochemically breaking down plastic at temperatures above 350°C in the absence of water. This process melts the plastic and changes its chemical composition, turning it into a boiling liquid and eventually a gas. As the gas escapes, it is cooled down with water and converted into oil. This oil can be further processed to produce diesel, kerosene, and gasoline. While this method may not be the most energy-efficient, it is still a way to complete the life cycle of plastic and potentially reduce its environmental impact.
However, it is important to address the misleading recycling claims made by oil companies. An investigation by NPR and PBS Frontline revealed that the oil and gas industry used the promise of recycling to sell more plastic, despite knowing that large-scale recycling of plastic was not feasible. Internal industry documents and interviews with former officials exposed that the industry sold the public on an idea they knew was not economically viable. Even as early as 1974, an industry insider expressed doubts about the effectiveness of recycling plastic.
The investigation found that recycling plastic is costly and challenging, and it degrades each time it is reused, limiting its reusability. Nevertheless, the oil and gas companies spent millions of dollars promoting recycling to the public. This led to a false sense of environmental security, as people believed that recycling was an effective solution to plastic waste management.
While the oil industry claims to be committed to ensuring all plastic is recycled, the reality is that recycling plastic is a complex and expensive process. The investigation highlights the discrepancy between the promises made by the industry and the actual feasibility of recycling plastic on a large scale. As a result, it is clear that the oil companies' recycling claims were misleading, and the true motivation was to increase plastic sales.
Despite the misleading recycling claims, there are still efforts to address plastic waste and explore alternative solutions. Companies like OMV have developed the ReOil solution, which aims to extract fuel from plastic waste. This process has been successful, with a bigger and better ReOil plant established in 2018, producing outstanding results. Additionally, the Niutech Environment Technology Corporation in China has developed two methods for handling waste, including one specifically for transforming plastic into oil through low-temperature catalytic pyrolysis. This technology has been commercialized in several countries, demonstrating ongoing innovations in plastic waste management.
