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 of plastics and chemical recycling

The pyrolysis of plastics process diagram.

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:

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.

Q:

How does APChemi ensure compliance with different countries' environmental standards?
A:

APChemi has experience working with various international environmental standards, including strict UK incineration norms. For each project, we collaborate with local environmental consultants and emissions control equipment providers to ensure full compliance with local regulations. We provide emissions data from our systems to local partners who then design and guarantee compliance with local environmental standards.

Q:

Does APChemi have facilities for testing client materials before full-scale implementation?
A:

Yes, APChemi has a state-of-the-art R&D facility where we can test client materials to develop a Technology Performance Statement. Our facility includes pilot plants for pyrolysis (2kg and 100kg capacity) and pyrolysis oil purification (15L and 100L capacity). This allows us to validate technology performance with specific feedstocks before scaling up to commercial operations.

How pyrolysis and pyrolysis oil purification enable sustainable advanced recycling of Single-use Plastics? 

A:

Pyrolysis transforms single-use plastics into pyrolysis oil through thermal decomposition in an oxygen-free environment, offering a sustainable recycling path. The subsequent purification of pyrolysis oil refines it into high-quality feedstocks for new plastics production (PUROIL&#;), closing the loop on plastic waste and contributing to a circular economy, while reducing the carbon footprint by 50 to 70% compared to incineration.

&#;

Q:

How biochar captures carbon?

A:

Biochar, a type of charcoal made from organic waste, sequesters carbon by trapping it in a stable, solid form, preventing it from returning to the atmosphere as carbon dioxide for centuries. This process effectively reduces greenhouse gases and offers a scalable, investment-worthy solution for carbon capture and storage.

&#;

Q:
How can plastic waste be converted into naphtha/SAF/diesel?

A:

Converting plastic waste into naphtha/SAF/diesel involves several steps:

1. Upgrading plastic waste to a quality suitable for use as feedstock in a pyrolysis plant.Upgrading the

2. Pyrolyzing the plastic waste to convert it into pyrolysis oil.

3. Purifying the pyrolysis oil to remove catalyst poisons and corrosives&#;our pyrolysis oil purification technology can add immense value here.

4. Fractionally distilling the pyrolysis oil to separate the diesel fraction.

5. Hydrotreating and mild hydrocracking.

6. Adding additives to enhance the stability and performance is if necessary

Starting with your specific raw materials, you can establish a technology performance statement in collaboration with our research and development facility before venturing into commercial-scale investments.

&#;

Q:
Which types of raw materials can APChemi's technologies effectively process?

A:
APChemi's advanced Pyrolysis technology is versatile and capable of processing a variety of materials including mixed plastics, tyres, and biomass all in one reactor. Additionally, our Pyrolysis Oil Purification technology is specifically designed to handle mixed plastic waste, even when contaminated with challenging materials such as PVC, PVDC, PET, and more. This technology meticulously removes contaminants including Chlorine, Oxygen, Fluorine, Bromine, Nitrogen, Silica, and Metals from Pyrolysis oil. The result is a highly purified pyrolysis oil, ready to be transformed into valuable products such as food and pharma-grade circular plastics. Furthermore, our plastic to synthetic bitumen technology is adept at converting mixed plastic waste into value.
