Choice of location is key.

Being close to (but higher than) a natural watercourse solves the human waste problem with simple drainage, as the loss of land drainage pumps and commercial water extraction will raise groundwater levels hugely and toxin removing reed beds and other forna/flora are surprisingly efficient at breaking down nasties. they also proliferate surprisingly fast in the sort of marginal water environment that would form in no time.

Burning waste oil (sump oil, old chip fat Etc) in converted stoves produces far less ash and requires less volume for a given heat output than solid fuel and is more easily stored... I have one 1200 litre UV resistant tank and access to several more.

Plastic food containers (which would have already been cleaned of food remnants) make tremendously usable building materials by either filling them with earth and using as bricks/stone, for windbreaks, enclosing areas etc, or by using empty/sealed as an efficient insulation blocks.

Plastic bags/wrapping can be welded together (with practice) and used to protect items from the elements, insulate drafty shelters/walls/floors, or as a cover to encourage early growth of tender plants.

Iron oxide (rust) has a surprising number of uses, so you can leave your clean tins, to degrade naturally, outside. Clean aluminium cans can be cut with scissors and stored as flat sheets, in a small area awaiting use.

Wood/paper ash can be kept and used in water to create an alkaline solution that can be used to clean and disinfect. (moderately). It can also be used to adjust soil PH when growing food plants and mixed with boiled and curdled milk it creates a very strong glue, capable of joining any porous material.

In a long term situation, there should be little waste anyway, so finding the raw materials is likely to be harder than disposing of the waste it creates.
