Pyrolysis, specifically multi-stage pyolysis in an oxygen vacuum has the ability to deal with far more than just plastic waste. In stage 1 the temperature is maintained at a low level. Stage 2 at a higher temperature is used if there are contaminants left from stage 1.
This technology should be paired with an effective recycling policy (recycle all material that can be cost effectively recycled) and diversion (divert what cannot be processed by the pyrolysis (batteries, pyrolysis is not effective on solid metal it is effective at removing coatings from metals).
It makes significantly more sense than introducing producer responsibility charges which don't impact waste but simply collect revenue for the government!

Dealing with WASTE PLASTICS in Ontario using pyrolysis?
Is it the solution to Landfills, Waste and Energy that we have been looking for?

Thanks for this Dan,
The pyrolysis system look like a good solution to the immediate problem of plastics pollution since 5 t of plastics is used to produce 4000 litres of fuel which displaces 4000 litres of diesel from the O&G industry which is produced from a much larger quantity of crude (not to mention all the CH4 emissions along the way). If the CO2 is captured and used in greenhouses to grow food then that’s an another co-benefit.
Curious about one thing: 5 t of plastics produces less than 4 t of fuel so there’s a ton or more of solid waste which should be mainly pure carbon—since all the volatiles have been driven off. Is this is in a form that could be used in some way? Re the dioxin question, the pyrolysis process should break down most of the complex chemicals, which is good. In a landfill they may eventually leach into groundwater.
Longer term of course we need to reduce the use of plastics, but we will always have plastics. We can’t build wind turbines or EVs without them!
Typically emissions from burning natural gas for example to heat a pyrolysis kiln are released into the environment. We are proposing to capture these emissions and sequester them in plants grown to feed people.
There are two technologies at play. Thermal decomposition is not incineration. Thermal decomposition typically separates carbons (reducing potential emissions!) and other solids from hydrocarbons in plastics or other waste streams. I am talking about incineration for the pyrolysis derived hydrocarbons or fuel. Instead of assuming that all incineration is bad, I am proposing that you look at the science of the incineration. For the time being we are stuck with diesel and the various diesel alternatives as a source of fuel for transportation. Mixing pyrolysis derived fuels with the various diesel fuels (bunker fuels and so forth) reduces the overall diesel emissions significantly. 10% pyrolytic fuel and 90% diesel reduces the overall diesel emissions by 20%! Compare this to biodiesel which when you add the emissions from making the biodiesel back to the emissions from burning the biodiesel, you end up producing more greenhouse gas emissions than result from burning regular diesel.
To the best of my knowledge there is no way to mix plastics from different technologies or to clean plastics of contaminants (the person who takes food grade plastic, stores rat poison in it and puts it out for recycling). We need solutions that work for all materials and all situations.
Essentially I am proposing that the smartest path to the greatest greenhouse gas emission reduction involves using real science that exists today to solve problems now and not hope that people will change how they will do things in future through taxation or other attempts to force behavioral change. This won't work in the short term. I welcome long term strategies that make sense but lets also make a difference today.
