Infrastructure supporting the circular economy and resource recovery: energy-from-waste, anaerobic digestion, and recycling facilities.
Environmental and waste assets earn on throughput plus output. The core is a contracted gate fee, a price per tonne to take and process waste under a long-term municipal or commercial contract, layered with the sale of what the process produces: power and heat from energy-from-waste, biomethane from anaerobic digestion, recovered commodities from recycling.
That second leg is where the risk lives: output revenue is exposed to power and commodity prices, so margins range from the capital-heavy stability of energy-from-waste to the thinner, more cyclical economics of recycling. The references below work through all three.
