SAF fuel made from Sewerage?
Guess some farmers got plenty of muck???

Somebody with thought disorders!

Light oils come from growing sunflower or rape seed not sewage. If rain falls then some farmers will make a shilling or two!

Will that be some bright spark growing oilseed with biosolids? Claiming reduced fert inputs due to the sludge.... and making it seem more sustainable blah blah blah? Running 8 wheeler bulkers from sewage plant to farm with 20 tonnes of sludge isn't going to be C neutral......is it?

Absolutely not!

What would be a more a better outcome for the Sludge, Landfill ? Dumping at Sea ?
Is recycling sewage that’s already been through an AD plant to generate electric not better than digging up Phosphate and making N from gas ?

Sewage sludge should end up on the land where it originated. Unfortunately, it usually contains plastic crap that no land-owner wants plus oils and fats. It should never be sent into rivers or the seas. It could be screened and treated so that it becomes a useful compost. However, water treatment companies do not want to spend a penny.

I agree, it should be recycled 100%, without elevating levels of pollutants within soils so that future food production and habitats aren't compromised..... straightforward sh!t is fine, it's just the modern cocktail of other consumables that gets into the system that sometimes isn't so fine!

I was more taking the pee, in that here we go again with some new greenwashing bulls**t to make flying seem acceptable in the eyes of the unsure consumer...... 'don't worry everyone we're being super innovative and you can all keep flying and not bother a jot about the need for humans to deviate from the business as usual trajectory'. f**king ridiculous!!

It makes no difference what is used as fuel for a highly destructive jet engine. Jets require enormous volumes of air that contains oxygen in order to operate. Biofuels will make no differences to the amounts of nitrogen dioxide and carbon dioxide emitted into your air.

if humans were meant to fly they wouldve had wings

 

[dave78+]

People who fly at high altitudes inside transatlantic aircraft only have the benefit of 73% of sea-level pressure of air. This means that their lungs are not fully inflated but are instead retracted without their knowledge. For the duration of their flights, they suffer from oxygen deprivation (hypoxia). Travel agents do not provide holiday-makers with such information. I do not foresee that the operators of planes with jet engines are ever likely to be buying fuels derived from sewage.

They will need public support if they want pure sewage.

Just drop this bilge man. Seriously. Go and learn the physiology and come back- nobody's lungs are 'fully-inflated'- it doesn't matter anyway because at rest the rate of exchange between the outside air and the blood is perfusion limited.

Are there any known health effects from this ? I know a few ex cabin crew and they all seem pretty healthy to me.

The answer is probably yes. However, they are complicated and subject to arguments galore. There are various other methods of being deprived of oxygen. I myself suffered from a low cabin pressure 30-years ago and was diagnosed 5-years later with an inner-ear tumour known as an acoustic neuroma. I think flying is a bad human habit.

In the UK, a considerable amount of used cooking oils and fats are disposed of via kitchen sink or toilets. This unlawful habit causes fatbergs that risk flooding if a sewer becomes blocked. I think that water treatment companies should pay to have their sludge taken away for processing and a lawful means of disposal. Unfortunately, there seem to be insurmountable obstacles that bar such a business. Most of the sewage ever produced in the UK before the construction of sewers went onto the land.

Still does. Where do you think the sludge from sewage works ultimately ends up?

Rivers and the seas.

I see what you did there

When doing some research about 14-years ago, I looked into the death of a young singer named Lena Zavaroni. I found my document today on an old memory stick. Lena had died aged 35-years in a Cardiff hospital following neurosurgery for an alleged mental illness. She died as a result of an infection.
I had concluded that Lena had so often been subjected to abnormally low barometric and aircraft cabin pressures that she had become a victim of decompression sickness. She had suffered with depression and anorexia for many years. However, anorexia is not mental illness. My view had been and still is that her brain had nothing wrong with it and that she had never be properly diagnosed prior to undergoing neurosurgery.
