Kruno,

For the purposes of my own research here, I’m not considering sewage as part of solid waste. I once read about the active market that used to exist in and around London for domestic toilet waste - and indeed would be taken to agricultural use. That disappeared with structured sewage systems. It arguably didn’t smell good and probably had health implications. But again, replacing a local solution for a fast-paced industrial one makes people less aware of their own impact in the world. Allienated of their own shit.

Don’t know if Alexandre Freire is still on this list, but I remember he telling us that the first sustainability measure he and his brother had to consider when building a house in an island off the coast of Sao Paulo state was precisely that of recycling their own shit - as most of the island is inside a natural reserve.

First of all, there must be a steady influx of recyclable materials, preferably already cleaned up and sorted according to type and quality. There must be an industrial plant with the proper equipment, methodologies, workforce, sources of energy, social responsibility measures and environmental licenses. Finally, there must be an active market willing to buy recycled materials."

There is steady influx (we go to toilet all the time), it can be sorted (solid to solid, liquid to liquid), mechanisms can be installed locally (your own separating toilet, no to centralized filtering and sewage plant, your own composting facility), source of energy is gravitation and ventilation (that can be powered locally by solar), social responsibility actually only requires all to sit down when at composting toilet so the process of separation would continues (as it is already done in our bodies), but this can be further developed by design. And active market is agriculture (ideally permaculture) that needs manure - compost from solid and nitrogen rich fertilizer from liquid. Can that be argued as cradle to cradle circle?

New roads were made, mayor was wining votes, toxic sludge was decomposed. I can't see the need for sewage system, plants, energy, filters, etc, as toxicity was still there, in the ground, ready to be taken by rains to drinking water and further to the environment.
