Gate fees, the avoided cost of disposal

A dairy, a food factory, or an abattoir pays to dispose of sludge, waste liquids, and screened solids. When the landfill refuses the load, that cost is stranded. BioJejak matches the waste to a biogas plant and records the gate fee the plant is paid to take it, the same cost the producer would have paid for disposal. The tanker is scanned in, and the biomethane, bio-CNG, and biofertiliser that leave carry that intake on the record. The purpose is a disposal cost turned into a paid, verified feedstock.
