The correct answer to your question - it all depends.
Tipping fees are market driven. In areas where environmental policy is aggressive, the fee can be quite high. In other developed areas it could be half the high end price. In less developed countries, $ 10 per ton is fair game. While the gate fees may be posted, you may need to share the revenue with the collector of the wastes.
Tires in the US have varied prices for disposal for much of the same reasons. Again, you need to share the tipping fee revenue with the collector - hauler. Steel from tires is priced cleaned and delivered to the steel mill. If you deal with a broker or scrap yard, you could lose 50% of the steel mill price. Size is a big issue. Cleaned and under 4 inch in length is ideal.
Pyrolysis oil, if clean, trades at a discount to WTI as there is no established market for it yet domestically. If it dies not meet ASTM standards then the discount can be $ 20 per barrel. Tank ready pyrolysis diesel is a different story. It will get closer to the wholesale price of fuels. There can be a big gap between retail (after tax) and the wholesale (pre-tax).
Unless there is a firm industrial buyer or other captive buyer, you are often at the mercy of the power distribution monopoly.
As for carbon credits, these are more of a political creature than conventional income sources. Some credits are fungible between markets and others are not. They need to be measured and independently verified before they can be marketed. Given the typical fixed costs to verify the volumes, generators often will wait a year or so to bite the bullet. From a cash flow perspective, they should be treated as deferred revenue.
The amount of energy derived from the system depends on the type of the input, the amount of inert elements which cannot be converted, the inherent humidity of the feedstock, the size of the input and so on. If you have a single unit, you need to consider downtime for cleaning out the system, preventative maintenance and a good annual overhaul. So, in a 24 hour day, look at an average of 20 hours of productive time. So, when the supplier says you will get x tons per day, are they talking per gross hour or net hours?
