# what are the cons of converting plastic to fuel

I have been trying to read how to fix plastic problems, there seems to be 3 outstanding solutions

1. Re-use
2. Recycle
3. Decompose to Fuel

Recycling is expensive, requires lots of water and the quality degrades on each recycle. I can partially understand why companies won't recycle

However I am unable to understand why would we not decompose to fuel. I have tried reading following articles:

It seems the primary way is Anhydrous pyrolysis requires no water, limited sorting and seems to convert 80% of plastic to fuel. I am unable to understand why would everybody not do this ? seems a viable solution and a profitable business

• Perhaps better is to use plastics as fuel directly, in high capacity, high temperature facilities, providing electricity or hot water. – Poutnik Aug 17 '19 at 7:58
• Following the previous comment, what kind of "fuel" are you looking for? Not all fuels are made equal. Wood is useful as a fuel, but so is ethanol. – Buck Thorn Aug 17 '19 at 10:08
• @Poutnik using plastics as fuel directly has more pollution impact than converting and using it. – Gaurav Shah Aug 17 '19 at 11:18
• @BuckThorn Looking at petroleum fuel - diesel, petrol etc – Gaurav Shah Aug 17 '19 at 11:18
• @Gaurav Shah I would say the opposite. There is environmental impact of conversion and small local device combustion has worse parameters. – Poutnik Aug 17 '19 at 11:24
