No? My guttering is all metal? Plastic guttering is a very unsustainable thing to do... Mine is cast aluminium on the chapel and powdercoated and aluminium, I assume extruded, on the new building.
However: the foul water pipe from pumping station to reed bed would be plastic, of an inert quality, buried 60 cms under ground.

In order to use human excrement safely on food crops, it needs to compost for a minimum of 3 years.

Which is why reed beds are better really... Mind, I am only using that in the food forest, where crops are perennial, as per guidelines.
Annuals would absorb "bad stuff" into their edible parts, whereas trees, shrubs etc filter this out themselves...

I have very little plastic on site, both in my buildings, including the house, and outside.
Exceptions: IBT tanks for water collection and things like chainsaw, strimmer, hoover, lawnmower, drill, where it is impossible to get ones that don't use plastic... There is plastic on the car as well

Thank you @Hanneke for the information. So using the human excrement compost after a year on trees and shrubs should be ok?

Can I clear something up.
Nothing wrong with using plastic in the right contexts. It's lightweight, durable and as strong as alternatives.
It also takes less energy (less embodied carbon) than some alternatives to process.
And it *is* recyclable.
So let's not damn all uses of plastic please.
The issue is single/disposable use of plastic.
Not use of plastic per se. The message has been corrupted by well meaning, but information poor people.

Mind, in the UK, if the excrement producer is say, me, there is no risk of oral-faecal spread of pathogens as there simply are none. Obviously, this is only controllable if you live in a small social unit, in my case, 1. Then the reason for not being allowed a compost loo:
Making medicine
Having clients who, by the time they get to me, are often very ill! I have seen a few cases where years of deteriorating health was due to parasites picked up on an exotic holiday....
Do the maths if they use your compost loo...

Guttering, of the plastic variety, is almost classed as single use! It deteriorates rapidly exposed to UV and needs to be replaced every 3 to 5 years!
However, my ex-orange juice IBTs will last me a LOT longer. Plus: re-used rescued from landfill
