“Advance recycling” and “chemical recycling” including waste-to-fuels, plastic-to-fuels
Advanced recycling, also known as “chemical recycling,” is an umbrella term for processes that use heat or chemicals to turn plastic waste into fuel or reclaimed resin to make new plastic.
Many so-called “advanced recycling” projects have emerged in recent years in response to a global explosion of plastic waste. More than 90% of it gets dumped or incinerated, according to a landmark 2017 study published in the journal Science Advances.
Not only is all this plastic rubbish choking landfills and despoiling oceans, it’s contributing to climate change because it’s made from fossil fuels. At a time when all of us are trying to find ways to reduce emissions, the oil industry is doubling down on plastics. Plastic production – which industry analysts forecast to double by 2040 – will be the biggest growth market for oil demand over the next decade, according to the Paris-based International Energy Agency.
So they need to sell a story that all this plastic rubbish can be recycled. It can’t.
Most of the advanced recycling proposals use a form of pyrolysis, the process of breaking down matter using high temperatures in an environment with little or no oxygen.
Pyrolysis has been tried before on plastic. British oil giant BP Plc, German chemical maker BASF SE and U.S. oil company Texaco Inc – now owned by Chevron Corp – all separately dropped plans to scale up waste-to-fuel pyrolysis technologies more than 20 years ago due to technical and commercial problems.
These processes consume large amounts of energy, generate toxic waste, such as dioxins, and are incapable of capable of transforming unsorted garbage into high-quality fuel and clean plastic resin. Instead what you get is highly contaminated synthetic gas (syn-gas) and a range of toxic waste streams.
